Test Your Foods for Starch

STEM Activity

68 reviews

Have you ever heard about starchy and non-starchy foods? What is the difference? Starchy foods contain the carbohydrate starch, which is converted to sugar (glucose) inside our body for energy production. How do we know which foods contain starch and which do not? There is a simple chemical test that you can do to detect starch, which involves an iodine solution. The iodine solution turns any food that contains starch dark blue. Try this activity and watch it in action yourself! Read more

Make String from Algae

STEM Activity

225 reviews

Did you know that the seaweed you've seen in the ocean or even eaten as a snack is inspiring innovators to imagine new materials? Large brown algae, like kelp, contains polymers—long chains of molecules—that are more environmentally friendly than the ones in most plastics. These natural polymers (alginates) could eventually be used to create sustainable everyday objects. Try your hand at using a bit of chemistry to turn biodegradable polymers from algae into your own custom… Read more

Color-changing Cabbage Chemistry

STEM Activity

60 reviews

What if you could take a single liquid, and change it into a rainbow of colors without using food dye. You can! In this activity you will use red cabbage to make what is called an indicator solution. Indicator solutions can change colors depending on what you add to them. In this case adding something acidic (like lemon juice) will change it to one color while adding something basic (like bleach) will change it to another. Try and see how many colors you can make using different household… Read more

Dissect a Flower

STEM Activity

93 reviews

Springtime is when nature comes back to life. Trees are growing their leaves again and flowers are sprouting, displaying their beautiful colors and spreading their delightful smell. But have you ever looked at a flower in more detail? What parts do flowers consist of? Are all flowers alike? In this activity, you will find out by dissecting, or taking apart, a flower piece by piece. How many plant parts do you think you can identify? Read more

Human Body Ratios

STEM Activity

29 reviews

Our bodies are amazing! They are full of mysteries and surprising facts like this one: did you know that you are about a centimeter taller in the morning, when you have just woken up after hours of lying down, than you are in the evening? You might never have noticed it. These interesting facts only reveal themselves when you look closely, measure, and compare. That is what this activity is about: measuring, comparing, and discovering how the human body measures up. Read more

Stacking Liquids

STEM Activity

63 reviews

Did you know that not only can solid objects sink or float, but liquids can, too? It is actually possible to stack different liquids on top of each other in layers. The key is that all the different layers must have different densities. You can stack them by either picking several liquids with a range of densities, or by varying the density of one liquid by adding chemicals like sugar or salt to it. If you choose colored liquids, or add food coloring to each layer, you can even create a whole… Read more

Make Marbled Cards Using Science!

STEM Activity

86 reviews

Do you like both, arts and science? Then this is the perfect activity for you! You will create beautiful marbled paper cards and practice science at the same time! The only materials you need are shaving cream, food coloring, and sheets of paper. It might get a bit messy, but that is part of the fun! Read more

Measure Surface Tension with a Penny

STEM Activity

21 reviews

Have you ever noticed how, on a rainy day, water forms droplets on a window? Why does it do that instead of just spreading out evenly over the whole surface? And what could that possibly have to do with washing the dishes or doing laundry? It all has to do with something called surface tension. Try this activity to learn more! Read more

Build a River Model!

STEM Activity

117 reviews

Earth is a very watery place! More than 70% of the Earth's surface is covered by water. This is due to the many water bodies that can be found everywhere on our planet. What types of water bodies do you know? They are all very distinct from one another in their appearance, size, shape, and movement. In this activity, you will explore the distinct characteristics of a river by creating a river model inside a pan with sand, pebbles, and real water! After that, you can continue to model other… Read more
