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 food science activity, learners conduct an experiment that demonstrates the importance of light to plants.

In this physics activity, learners attempt to lift a jar full of rice using only a spoon.

This is an activity about friction as well as kinetic and potential energy.

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.

In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.

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 review the history of gumball machines and explore potential and kinetic energy, while working in teams to build a gumball slide.
