In this physics demonstration, learners will be surprised when a lemon slice appears to magically levitate within a pint glass. This is a simple trick that involves several complex physical...

In this math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit. Learners practice using different...

Each learner chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days. By weighing the gum before and after chewing, they can determine the amount of mass...

In this activity (4th activity on the page), learners test to see if saliva is necessary for food to have taste. Learners dry their tongues with clean paper towels and then taste samples of salt,...

In this design challenge activity, learners build a shock-absorbing system that will protect two “astronauts” when they land. Learners follow the engineering design process to design and build a...

In this hands-on activity, learners make the world's simplest Cartesian diver, using only a plastic bottle, some water, and a condiment packet. A Cartesian diver is a classic science...

In this activity, learners follow a recipe to make hollandaise sauce. Learners discover how cooks use egg yolks to blend oil and water together into a smooth mix. In chemistry, this mixture is...

Using yeast, sugar, and water, learners create a chemical reaction which produces carbon dioxide (CO2) gas inside a 2-liter bottle. They use this gas to inflate a balloon. This reaction shows the...
