As a model of acid rain, learners water plants with three different solutions: water only, vinegar only, vinegar-water mixture.

In this activity, learners construct a simple air pressure launcher for paper rockets.

In this activity, learners make different shapes that hold exactly one mole of gas (air).

In this activity, learners examine raindrop bottles (prepared ahead of time) to observe in slow motion the behavior of falling droplets and explore concepts such as drag and terminal velocity.
