Learners will build a lung model to understand how their lungs and diaphragm work to make them breathe.

In this activity, learners explore clouds and how they form.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

This creative lesson plan provides a visual way for learners to gain knowledge about the finite amount of fresh water on Earth and encourages the discussion of the various ways to conserve this resour

In this space science activity, learners explore transits and the conditions when a transit may be seen.

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

Learners will understand the relationship between climate change and sea-level rise.

Learners observe a simple balloon model of an electrostatic precipitator. These devices are used for pollutant recovery in cleaning industrial air pollution.

Learners observe and discuss a vacuum cleaner as a model of a baghouse, a device used in cleaning industrial air pollution.

Using recycled materials, learners will design a transportation vehicle to carry an egg in an egg toss (a rudimentary model of a shock absorbent transport vessel).

In this activity, learners simulate the separation techniques that materials recovery facilities (MRFs) use and then design their own series of recycling techniques.
