In this activity, learners of all ages can become food scientists by experimenting with flour and water to make basic pasta.

In this activity about the relationship between food and energy (page 5 of PDF), learners conduct an experiment to compare how much energy is released as heat from two different foods.

In this activity about the relationship between food and energy (page 1 of PDF), learners observe and quantify the growth of yeast when it is given table sugar as a food source.

In this delicious activity, learners get to make, taste-test and compare their own "brands" of homemade strawberry ice cream.

In this activity, learners shrink the scale of the vast solar system to the size of their neighborhood.

In this two-part activity, learners will extract their own DNA from their cheek cells and learn how DNA is analyzed and used to solve crimes.

In this activity, learners build edible models of DNA, while learning basic DNA structure and the rules of base pairing.

In this kinesthetic activity, learners move pom-pom "ions" across a membrane to simulate how an action potential is propagated along an axon.

In this activity, learners use edible models of the DNA molecule to transcribe an mRNA sequence, and then translate it into a protein.

Learners build a simple solar oven from a shoebox, black construction paper, and aluminum foil. Over the course of a few hours, the oven heats up water enough to brew tea.

This is a classic exercise for visualizing the scale of the Solar System.

In this tasty activity, learners make their own ice cream any day of the year in an exploration of heat and cold. Highlights include freezing and melting and the transition from liquid to solid.

In this activity, learners will develop a method to test five similar-looking powders (baking soda, baking powder, cream of tartar, detergent, and cornstarch) with four test liquids (water, vinegar, i

In this activity about combustion and energy, learners observe a burning candle in a sealed jar and the burning of white sugar.

In this activity, learners create an electrical circuit and investigate how some dissolved substances conduct electricity.

In this experiment, learners will conduct chemical and physical tests to identify mystery substances.

In this activity, learners build models of comets, using edible materials, to learn about comets' structure.

Learners explore capillary action in plants (such as plants ability to move water from roots to leaves) in an investigation called Paper Blooms.
