This activity shows you how to make a mold terrarium using a jar and leftover food.

In this activity, learners investigate feeding relationships. Learners complete a food web and then make a mobile to represent a food chain.

Make snack time into measuring time and learn to read Nutrition Facts labels. Try this when you’re using “pourable” foods, such as cereal, yoghurt, or juice.

This is a hands-on activity that uses bread and household materials to grow mold. Learners collect dust from a room, wipe it on food, and contain it. One to seven days later, mold has grown.

Use this activity to build division and number sense into any snack time or whenever there is a limited set of things to share among a group: If we deal these out, could everyone get two pieces?

In this activity, learners will estimate how many seeds are in a fruit or vegetable, then count to find out. The result: mix estimation with healthy eating.

In this activity, learners explore how eating unhealthy food can damage a heart and arteries.

In this introductory activity, learners discover that sugar and food coloring dissolve in water but neither dissolves in oil.

Choose a recipe to double (or triple, quadruple, or halve). Show everyone the recipe and engage them in figuring out: How much will we need to increase the recipe to feed everyone?

This is a quick activity that shows how large amounts of rock and sediment are added to the edge of continents during subduction.

In the kitchen, learners can perform their own density investigation.

In this science trick, learners get an egg to stand-up on its long-axis vertical to a table's top.

In this activity, learners thread gumdrops together to make a model of a polymer.

In this activity (last activity on the page), learners make a model of the eardrum (also called the "tympanic membrane") and see how sound travels through the air.

In this activity, learners make their own rock candy. Crystals will grow from a piece of string hanging in a cup of sugar water. The edible crystals may take up to a week to form.

In this activity, learners explore how their sense of smell affects their taste buds. Learners taste different flavored jelly beans while holding their nose.

Your tongue can sense about 6 different flavors (salty, sweet, bitter, sour, umami/savory, and fat), but your nose provides a lot more "taste" information than you realize when you eat.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

In this physics demonstration, learners are challenged to break a raw egg just by squeezing it. Learners will be shocked by their inability to complete the deceivingly simple challenge.
