KiwiCo Review: Kiwi Crate for 5-8 year olds – THE HUMAN BODY


This is a fabulous hands on box for learning about the human body! There is a giant wall poster that shows multiple systems including: skeletal, nervous, digestive, and muscular.

Make your own x-ray of a broken bone

We loved the ‘magic paper’ that allowed us to explore the skeletal system and make our own x-ray of a broken bone. We started with a clear sheet of plastic that we blu-tak’d to the poster and then carefully applied bones to create the hand and forearm (ulna and radius). We put the sheet of plastic on top of the ‘magic paper’ and placed it in bright sunlight; later (in a dark room), we removed the plastic and admired our x-ray of a break in the radius. Note: There are a range of bones that you can choose from and they can be removed easily so that you can try more projects.

Tip: You can also use the magic paper to create your own experiments! We used black paper to create a Stegosaurus silhouette and thus created our very own dinosaur magic trick!

Make your own stethoscope

Provided in the kit were the materials to make our own stethoscope – it really works for listening to a heartbeat! It also comes with a fun double-sided wipe-clean examination sheet so that kids can play doctor.

Make your own plush organs

The art project for the box means you can make your own super cute plush organs (brain, heart, and stomach). The felt comes with pre-pierced holes which makes threading easier for children.

Want more ideas for learning about the human body?

The Explore magazine in the kit gives some craft ideas that you can do at home. We’ve used various resources such as an ExperiSenseNZ Human Body learning kit, Factivity: Amazing Body Sticker Activity BookWrite & Wipe Wellbeing Book, and a poseable art mannequin for exploring movements and joints.


This is not a paid review. I spent a lot of time searching the internet to find out more information about the Kiwi Crate and Atlas Crate boxes before deciding to try them and found the blog posts / photos that people shared were really useful!

What I like about the Kiwi Crate kits is that they use a combination of Science, Technology, Engineering, Arts, and Mathematics to explore a concept or idea. There’s no obligation to sign-up in an on-going capacity so it’s easy to tie them in with birthdays / Christmas; the boxes are quite compact so they also store easily in a cupboard for bringing them out on a rainy day. Mind you, this only works if you spot the package on the door-step first – children become quite adept at recognising the green Kiwi Crate box and screaming with delight at it’s arrival!

The boxes are sent randomly so there’s no way to know what will come in the future; however, you can log-in to your account at the start of each month to see what box has been selected. Your box history is kept which means that even if you cancel and then pick-up again the following year they can make sure that you aren’t sent repeats of boxes.


The Kiwi Crate is aimed at ages 5-8 years. It comes with a copy of the Explore magazine which opens with a fun comic about Steve the Kiwi and his friends. [As a side note, these are made by an American company despite the use of our New Zealand native bird]. These comics are really approachable for younger kids and a great way of exploring the concepts being introduced in a relateable manner.

The Explore magazine provides a range of information on the topic, it might include some simple games or tricks to try at home, and provide ideas for additional crafts / activities using simple materials. It also has a sticker [unique to each box theme] to put on your Kiwi Crate chart.

The box also includes an instruction manual and the materials that you need to build the main craft. Generally, there are two activities to do – one that is more art related, and one that is more mechanical engineering. What makes the kits special, is how well crafted the engineering components are. They really are designed for the intended age group so that they can either build themselves or help assist an adult. There are handy visual images and checkpoints to make sure that things are aligned correctly. There is no super-bonding-fingers-together wood glue to use with these projects (which makes them great for highly sensory children); instead parts come with double sided tape finely engineered on so that you just need to remove the backing strip of paper.

EXPERISENSE NZ REVIEW: Exploring Science Homeschool Box

Lava lamp experiment


This kit is all about having some scientific fun with experiments and adding in artistic flair. I love adding a kinaesthetic dimension to our learning! The box provides seven learning activities to do that are fully aligned with the NZ Curriculum and are highly adaptable to age, interest, and special needs.

The kit comes with a guide that outlines how to conduct each experiment and also provides information on the scientific principles being demonstrated. It’s a great way for kids to build on prior knowledge, as well as asking new questions!

The ExperiSense NZ Science Box sells for NZD$27 online; I’ve bought and reviewed a number of their boxes with this one being received free in exchange for an honest review.

How to make your own lava lamp

Have you ever looked at a lava lamp and wondered how they work? Well, this experiment will let you make your own temporary lava lamp! We loved it to so much that we did it twice.

Fundamentally, it comes down to the fact that oil and water do not mix. This is because they are different densities (and oil will actually rise up to float on top of water – which you can see happen in the experiment). As you slowly drop food dye into the oil, watch how the droplets retain their own separate form (“immiscible” was our cool new word of the day). Once water is added, the food dye will slowly dissolve into the water but differences in density mean the oil will rise to the surface.

The magic happens when carbon dioxide gas is created by introducing a fizzing tablet! The chemistry being demonstrated means that as the solid tablet dissolves, bubbles of water-and-gas raise to the surface. As the carbon dioxide gas dissipates, density changes causing the bubbles to sink. FYI – in a real lava lamp what you are watching is caused by thermodynamic changes (i.e. the application of heat).

In our first experiment, we used 1/4 tablet, red + yellow food dye, the oil provided, and the cup provided. In our second experiment, we used 3/4 tablet, a recycled glass jar, our own kitchen oil, the blue dye provided + some red dye.

Extra Activities

The lava lamp experiment looks at both density and states of matter. You may want to explore these further with simple experiments such as:

Why do things float or sink? A great way to start is in natural environments, such as a river or beach, by gathering up materials such as driftwood, shells, rocks, and mangrove pods to experiment with. At home, consider experiments with buoyancy such as why an orange will float (unless you peel it!).

How does water demonstrate states of matter? I love using water to demonstrate how something can so easily change forms between solid > liquid > gas. A fun experiment relating to buoyancy is to freeze water in a bag (food delivery boxes can be great sources of pre-formed ice) and create an iceberg diorama in a sink or bucket; have fun seeing what toys can balance on the iceberg before it melts!

Oil and Water Painting

We really enjoy making marbled paper using shaving foam; this was our first time using oil. We used a large plastic tray and simply recycled our lava lamps (with some extra colours dropped onto the surface of the oil). We chose to use our own paper and dye, in addition to the card stock provided, and made lots of beautiful art work.

Tip: Have layers of cardboard and paper towels beneath your art so that it can absorb the excess oil. We waited until the next day (once the dye was dry) before layering the artwork between layers of paper towels and popping in hot water cupboard to finish drying.

Magic Trick: Once the paintings are completely dry, the oil will have changed the appearance of the paper but any ‘virgin’ paper will still appear white. If you hold the art up to a bright light then not only can you see your beautiful colours clearly but any ‘white’ corners will disappear and smokey ‘shadows’ will appear in their place instead!

How to make a rainbow

The kit comes with a very small prism that you can use to split light. As light enters the prism, it bends, and the different wavelengths will create a spectrum of colours as they exit. For us, the light exited onto the opposite wall and we found creating some shadow helped us see it more clearly. We lined up the prism with the sun after catching a wonderful rainbow that was refracting through our fish tank!

The kit also comes with a second rainbow experiment where a bendable ‘mirror’ is placed in a glass of water to reflect and refract light. We found this one a bit tricky but we did achieve a little colour splitting. Miss 6 actually most enjoyed casting shapes of reflected light onto the shadowed ceiling!

Extra Activity

Want to combine rainbows AND learning about the density of different liquids? Check out this fun experiment to make a sugar rainbow!

How to experiment with static electricity

The kit comes with a balloon, templates, and craft paper to make your own ‘jumping bunnies’ or frogs; we also had fun designing our own creatures in a variety of sizes. Rubbing the balloon energetically on clothes creates a temporary static charge which allows your creations to ‘jump’ or ‘dance’.

Extra Activity

Want to see and feel another invisible force? Pop one end of a straw partially into a balloon and secure the neck with a tight rubber band. Blow down the straw and watch the balloon inflate (just like a lung!) and then feel the air exit again out the straw! Talk about how some natural forces we can’t see (like gravity, or air in motion) but we can observe their effects on the world around us.

How to make magic tea

Beautiful colour changing butterfly tea!

The kit comes with two experiments for exploring acids and bases. One is experimenting with litmus paper and the other is making butterfly pea flower tea. I find the tea has a light floral flavour and like to drink it with a little liquid honey. When you brew it, the tea comes out a stunning vibrant blue; the addition of a little freshly squeezed lemon juice (changing the pH level) magically makes it a purple-pink colour!

Tip: Wet litmus paper can leave a yellow mark on benchtops (easily removed with Chemco) so it’s a good idea to place the strips on a piece of white card.

Tip: Hot water will have a more dramatic effect (than cold) when added to a teaspoon of baking soda (alkaline) or a teaspoon of baking powder (acidic).

Extra activities

Explore natural colour changing properties further by using a red cabbage to make a magic colour changing potion! Collect your magic molecules, make a potion, and use the rest to make your own litmus paper!

After watching how baking powder dramatically foams up when a little hot water is added, try making these light and fluffy scones and imagine how the baking powder helps the dough to rise when combined with the heat of the oven.

Life in Lockdown – Decorate our streets!

Making homemade chalk is easy a great way to connect as a family!

Life in New Zealand has changed rapidly. Our borders are closed, domestic travel restricted, our schools and shops closed, and we are asked to remain at home in order to restrict the spread of Covid-19. Cars are now to be used only for essential travel (the doctor, pharmacy, or supermarket) and people may only leave their house to walk nearby. Social distancing is everything.

Our big field trip for today was walking to the top of the driveway and drawing pictures that the kids in the houses nearby can see from their windows. Creating chalk, with a few simple ingredients from the supermarket, has been both art and science. It’s also a way to share a little love and kindness with the community around us.

Why not bring a little colour to yours?

Life in lockdown: Share some love and decorate our streets!

How to make home made chalk


  • Cornflour
  • Water
  • Food colouring
  • Cardboard tubes
  • Waxed paper / baking paper
  • Scissors
  • Sellotape or rubber bands

Note: Alternative ingredients include plaster of paris + tempera paint, or a 1:2 ratio of very finely crushed eggshell + flour.


  1. Prepare your moulds. Toilet paper rolls are a good size; I find a bread knife does a good job of sawing longer cardboard inner tubes into parts.
  2. Cover the bottom of your cardboard tubes with waxed paper and tape / elastic band into place. You then want to roll more waxed paper and slot it inside (you may need to trim to size).
  3. Pour cornstarch into a bowl and then add food colouring of your choice. Slowly add water and mix well. You want to add just enough water to create a very thick [viscous] mixture.
  4. Pour or spoon the mix into your moulds.
  5. Pop into a hot water cupboard (or somewhere warm to dry). You want as much of the water to evaporate as possible to dry before use (about 24-48 hrs).
  6. You can then removed from the moulds and let the kids have fun!


If you add too much water then it will have difficulty drying (and remaining contained within the moulds). Never fear! Treat it as a chemistry and physics lesson all-in-one for the kids. You have just created a non-Newtonian fluid 🙂 You can take your ooblek outside for messy play fun with the kids. Pour it into your hands and watch how it becomes a solid if you clench your fist but magically liquefies if you release the pressure!

Home Science: Make a colour changing magic potion!

These colour changing molecules can be changed from indigo to brilliant blue or bright pink with a few simple experiments!

Pigments are molecules that contain colour and the ones in red cabbage juice ( anthocyanin ) are pretty special. By adding a base or acid, we can both change their shape and their colour! The pigments are easy to collect and the basis for two easy home experiments: Colour Changing Magic Potions and Making Litmus Paper.

First, you will need to collect some magic molecules from a red cabbage: click here to find out how.


Change your purple cabbage juice to blue by adding a base and to red/pink by adding an acid.


  1. Pour your prepared red cabbage juice into two clear glasses or small bowls.
  2. Into one glass, stir 1 tsp of baking soda. Watch the solution turn blue – indicating that the pH has turned basic.
  3. Into the second glass, stir 3 Tbsp of white vinegar. Watch the solution turn red/pink – indicating that the pH has turned acidic.
  4. For fun, pour the glass containing vinegar into the glass containing baking soda and watch them foam! Tip: for less mess, pour both solutions into a big bowl!
Foaming magic potion fun!

Home Science: Making Litmus Paper

Make your litmus paper to test acids and bases – it’s easy!

You don’t need expensive chemistry kits containing dangerous chemicals to have fun doing science at home. This simple (and colourful) experiment will help you make you own litmus paper so that you can test acids and bases using simple household ingredients. You can also test these by making a colour changing magic potion!

First, you will need to collect some magic molecules from a red cabbage: click here to find out how.


  • Red cabbage juice
  • Paper towels
  • Water
  • Dishwashing Liquid
  • Lemon juice
  • Baking Soda
  • Baking Powder
  • Vinegar
Making home made litmus paper
Home-made Litmus Paper

Directions – Part 1

  1. You will need your red cabbage juice (cooled and strained) and some paper towels. I folded mine twice to make thick squares.
  2. Quickly dip / submerge the paper towels into the red cabbage juice. Don’t hold them under for too long as you want them to collect the colour pigments but not get so soggy that they fall apart. It’s a little like candle dipping – you may need to do a couple of dips to get a good colour.
  3. Place the purple paper towels on a clean tray (that won’t stain) and put them somewhere warm (like the hot water cupboard) to dry until the next day.
  4. You now have litmus paper! Cut them into strips for easy dipping.
Testing Acids and Bases

Directions – Part 2

  1. Using glasses or small bowls prepare the solutions that you want to test. Your litmus paper will stay purple in ph neutral solutions, turn red-pink in acidic solutions, and turn blue in basic solutions.
  2. Dip away!

We used:

Bases: soapy water, baking soda, baking powder.

Acids: vinegar, lemon juice.

Don’t worry if your experiment doesn’t go perfectly (ours didn’t!); simply use it as a talking point to discuss why things didn’t turn out as expected. In our case, the detergent and baking powder didn’t dissolve properly which meant that out litmus paper stayed purple (recognising the ph neutral water).

  • 1/2 red cabbage
  • Hot water
  • A food processor (or a big pot)
  • Bowl
  • Fine colander or flour sieve
Simply blending the red cabbage in boiling water produces amazing bubbles!


  1. Shred or coarsely chop the red cabbage.
  2. You can then choose whether to boil or blend. I chose blending and it’s meant to result in slightly better colour.
    • Boil: Pop in a pot with enough water to cover the cabbage and boil for 15 minutes.
    • Blend: Pop in a food processor with about 3 cups of boiling / hot water. Blend until the cabbage is finely processed and then leave to soak for 15 minutes.
  3. Allow the cabbage mixture to cool and then strain the juice into a bowl. Tip: The juice will stain so glass is great if you have it. I used a flour sieve to strain mine into a glass pyrex jug.

You now have the cabbage juice you need for your two science experiments!

Added Extras

You can also freeze leftover juice in ice cube trays to make all natural coloured icing for birthday cakes or cupcakes!

Caramel Crunch Cookies

Caramel Crunch Cookies

These delicious crunchy cookies are also a great opportunity to discuss science in the kitchen! STEM discussion points follow after the recipe 🙂


  • 125 butter
  • 1/2 brown sugar
  • 1 Tbsp maple syrup or golden syrup
  • 1 Tbsp milk
  • 1 1/2 cups plain flour
  • 1 tsp baking soda

Allergies: soy free, egg free, nut free.


  1. Start the oven preheating to 180’C / 350’F.
  2. Have a grown up mix the butter, sugar, maple syrup, and milk in a pot. Heat until the butter is melted and the mixture is almost boiling – you’ll be able to see the surface tension change as it begins to think about bubbling. Make sure that you stir constantly so that it doesn’t stick or burn.
  3. Remove from heat and allow the caramel to cool to lukewarm.
  4. Sift the flour and baking soda into the pot and mix into the caramel.
  5. Stir well and it will turn into a caramel coloured cookie dough.
  6. Roll the cookie dough into balls and flatten on a baking tray (either greased or lined with baking paper).
  7. Bake for 10-15 mins or until golden brown.

Science in the Kitchen (STEM)

  1. Gravity & Weight: When you’re using kitchen scales to measure out the butter, take a few moments to talk about why things have weight and why we weigh them. That butter would weigh about 20g on the Moon and about 315g on Jupiter.
  2. Solids, Liquids, Gas: It’s a good idea to have a grown up do the stirring with the caramel mixture as it gets very hot; keep young helpers interested by helping them to safely view the way the ingredients change. Ask them if the butter and sugar going into the pot are liquids or solids (the latter); then show them what happens when heat is applied (becomes liquid); as the mixture cools and is combined with the flour it’s state changes again (solid).
  3. Gassy Bubbles: Ask young helpers what’s different about the ingredients in this recipe. The answer is that it uses baking soda rather than baking soda. The baking soda causes small carbon dioxide gas bubbles in the cookie mix causing it to rise when it goes into the hot oven. Tip: Get the cookies in the oven quickly as the longer the mix is left at room temperature, the less the cookies will rise.
  4. Sweet Surprise: A great way to see baking soda in action is to make a candy version of these cookies. Have a go at making Hokey Pokey!
