Learners use red cabbage juice and pH indicator paper to test the acidity and basicity of household materials. The activity links this concept of acids and bases to acid rain and other pollutants.

In this activity, learners build a carousel toy that spins when pushed down.

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 engineering challenge, learners design and build a crane out of cardboard to see how heavy a load it can lift.

In this activity about ramps, learners explore and measure the rate at which spherical objects roll down a ramp.

Working in teams of four, learners build tetrahedral kites following specific instructions and using specific materials.

In this activity, learners experiment with creating various types of bubble solutions and testing which ingredients form longer-lasting bubbles.

Learners take on the role of environmental engineers as they design water filters.

In this activity, learners explore the relationship between electric charges and magnetic fields.

In this experiment, learners construct an equilateral triangle using graph paper, a pencil, protractor and ruler. They also make a "laser triangle" using a laser pointer and front-silvered mirrors.

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

In this activity, learners discuss and investigate how cameras, telescopes, and their own eyes use light in similar ways.

Learners recreate the classic egg-drop experiment with an analogy to the Mars rover landing. The concept of terminal velocity will be introduced, and learners perform several velocity calculations.

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 engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

In this robotics activity, learners find ways to express emotions and feelings using only body movements, not facial expressions.

In this activity, learners explore the human influences on the carbon cycle and examine how fossil fuels release carbon.

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.
