In this activity, learners discover the primary physical properties used to separate pure substances from mixtures.

In this activity, learners explore what happens when polarized white light passes through a sugar solution.

In this activity, learners will make their own slushies and learn some of the science behind how the process works.

In this activity (located on pages 23-24 of the PDF), learners are introduced to structural engineering and encouraged to practice goal-oriented building.

In this demonstration, learners observe the effects of air pressure. They will watch as marshmallows inside a bottle expand as a vacuum pump removes air from the bottle.

In this chemistry activity, learners are asked to form a hypothesis about the behavior of milk as household detergents act upon it.

In this activity (25th on the page) about learning and memory, learners explore a training method that animal trainers employ called "shaping." Working in pairs, learners will attempt to "shape" each

In this activity, learners explore chemistry and the microbial world by making their own sourdough starter and bread at home using only flour and water.

Learners set up three different bowls, each with a different mass of oatmeal. Learners monitor the temperature of the oatmeal and find that larger masses take longer to cool.

Perform this classic inertia demonstration to illustrate the transfer of potential energy to kinetic energy.

In this activity about olfaction (9th activity on the page), learners smell 10 different items with different odors, including some edible food items.

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.

In this activity, learners use food scraps from the kitchen to grow new vegetables.

In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.

DNA is the thread of life. Encoded in its genetic sequence is the information that makes each of us unique. This activity allows you to see long, stringy strands of DNA extracted from wheat germ.

In this chemistry activity, learners perform three chemical reactions in a sealed zip-top bag. Learners will record their observations and classify the changes as chemical or physical.

In this chemistry activity, learners use spaghetti to explore density and chemical reactions.

This is an activity about robotics programming. Learners will discover how precise programmers have to be as they instruct a friend to make a peanut butter and jelly sandwich.

In this genetics activity, learners discover how to extract DNA from green split peas.

In this activity, learners model hot spot island formation, orientation and progression with condiments.
