In this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate.

In this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates.

In this lab, learners evaluate the relative effectiveness of various chemical substances (i.e. garlic powder, bathroom cleaner, mouthwash, etc.) as antimicrobial agents.

In this activity, learners examine the different materials gardeners add to their soil, and discuss how these materials are important for plant growth.

Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

This is an activity (located on page 3 of the PDF) about the mixture of materials in bone and how they affect its strength.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners compare and contrast different forms of luminescence by observing how chemiluminescence, phosphorescence, and fluorescence produce or emit light.

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

In this activity, learners explore the concept of conducting or insulating electricity.

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

In this activity, learners explore and experiment how we can use our bodies everyday to get from one place to another.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

Learners carefully look at four known household crystals.

In this math lesson, learners explore the relationship between the thickness of a spaghetti bridge, the length of the bridge, and the amount of weight that can be supported by the bridge.

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

In this activity (on page 142 of the PDF), learners will compare breathing rates before and after hyperventilation to explore how reduced carbon dioxide levels in the blood lower the need to breathe.

Learners design their own experiment to determine conditions that either help or hinder the decomposition of carrots by soil microbes.

Learners investigate how drag affects the falling rate of objects.
