In this archaeology activity, learners consider ways in which excavating an underwater site is different from excavating a terrestrial site.

In this activity related to plant biotechnology, learners extract DNA from fruit to investigate how it looks and feels.

In this activity, learners extract DNA from wheat germ. Use this activity to introduce learners to DNA, biotechnology and genetic engineering.

In this activity, learners explore phosphorescence and how certain materials can absorb and store energy from a light source.

In this activity, learners will design a protective package for an egg that will allow the egg to withstand a fall without cracking.

The purpose of this plant biotechnology activity is to demonstrate the effect of changes in the environment on the growth and fertility of landscape grasses and crop grasses such as wheat and rice.

In this physical sciences activity, learners explore insulation. Leaners investigate how insulation can be used to slow down the conduction of heat from one side of a wall to the other.

In this activity, learners make an electromagnet motor to demonstrate the most basic method of changing electrical energy into mechanical energy.

In this activity, learners discover how solar energy can be used to heat water.

Learners construct and launch paper helicopters.

In this computer science activity about finite-state automaton (on page 45 of the PDF), learners use a map and choose various pathways to find Treasure Island.

In this activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

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.

In this activity, learners use a compass, powerful magnet, and copper magnet wire to build a special generator known as a dynamo.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.

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

In this activity, learners use a microscope to examine three different microbes: bacteria, yeast and paramecia. Educator will need to prepare the yeast solution one day before the activity.

In this activity, learners work in groups to build simple solar stills filled with salt water. After the stills are complete, learners observe what happens when they place the stills in the sun.

Learners play the role of materials engineers as they test the flexibility of different materials.
