Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

Design a vessel that tests the limits of wind power given a set of off the shelf and recycled materials.

In this activity, learners build a "pneumatic trough," a laboratory apparatus used for collecting pure gas samples over water.

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

In this activity, learners will use chemistry to create a night sky watercolor painting. They will experiment to learn the effects of mixing crayon, salt, and lemon juice with water color paints.

Learners observe a flask with a balloon attached over the mouth and inverted inside the flask.

In this activity, learners use a pneumatic trough (see related activity) to generate and collect pure oxygen.

Bones are stiff, which helps us lift heavy things and walk around, but they are also somewhat flexible, which lets them bend slightly.
