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.

The demonstration/experiment provides quick proof that air has mass.

In this activity, learners test the Law of Reflection based on experimental evidence. Learners produce raw data and explanations based on their data: pencil tracings of incident and reflection rays.

In this two part activity, learners work in pairs or individually to discover how vectoring the thrust from a jet engine affects movement of an airplane.

Learners will understand the relationship between climate change and sea-level rise.

In this activity, learners set up an experiment to investigate the effects of hot air on the path of a laser beam.

In this activity, learners explore the devices used over time to measure changes in temperature.

In this activity (Lesson 1), learners work in groups to create tide simulations.

In this activity, learners explore conservation of energy by experimenting with a solar cell light device.

Learners build and investigate pendulums of different lengths. They discover that the longer the string of the pendulum, the longer the time it takes to swing.

In this activity, learners calculate the number of milliliters of water a nearby tree transpires per day.

In this chemistry activity, learners use the lowered freezing point of water to chill another mixture (ice cream) to the solid state.

In this physical sciences activity, learners explore how passive solar design increases energy efficiency.

In this activity, learners build penetrometers to test leaf toughness. Biologists measure leaf toughness to study the feeding preferences of insects and bugs.

In this two-part activity about luminescence, learners explore the chemistry that happens inside glow sticks and other light producing reactions.

This activity helps learners understand how the angle of the Sun affects temperatures around the globe.

Through discussion and hands-on experimentation, learners examine the geological (ancient) carbon cycle.

Learners design their own experiment to determine which M&M color dissolves the fastest in water.

In this meteorological activity, learners get to build their very own anemometer (instrument for measuring wind speed) using a paper cup.

In this activity related to microbes, learners make slides of cells from an onion skin and Elodea (American or Canadian waterweed) to observe under a microscope.
