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

Learners examine the manufacturing process while they make picture frames from cereal boxes.

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

Using paper, paper clips, an index card, and tape, teams of learners design flying devices to (1) stay in the air as long as possible and (2) land as close as possible to a given target.

Learners build a simple electromagnet, then use this electromagnet to transform a yogurt container into a working speaker. They can connect their speaker to a radio and listen as it transmits sound.

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.

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.

Learners build simple catapults and use them to launch cotton balls.

Learners investigate weight by building a spring scale. They observe and record how it responds to objects with different masses.

Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Learners develop awareness and understanding of the daily air quality using the Air Quality Index (AQI) listed in the newspaper or online.

Learners investigate how drag affects the falling rate of objects.

Learners tour their school or home looking for sources of indoor air pollutants (IAPs).

Working in groups, learners model the continuous destruction and creation of ozone (O3) molecules, which occur in the ozone layer.

Learners create beautiful fluid motion. They explore fluid dynamics, surface tension, solubility, and buoyancy while mixing liquids together.

Learners develop an understanding of air pressure in two different activities.

Learners build devices from rubber bands to test for invisible air pollutants.

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

In this activity, learners determine whether thermal energy can be used for work.

In this activity, learners demonstrate and discuss simple circuits as well as the differences between parallel and serial circuit design and functions.
