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 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 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 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.

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 classic hands-on activity, learners estimate the length of a molecule by floating a fatty acid (oleic acid) on water.

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 on page 10 of the PDF, learners detect the amount of energy that can flow through a sodium chloride electrolyte solution with a light sensor.

Learners design their own experiment to explore the permeability of different materials such as soil, sand, gravel, and marbles.

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

From the Weather Watchers featured theme on the CYBERCHASE website. Learners will conduct experiments to discover how air temperature and humidity work together to make condensation, dew, and fog.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

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.
