In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

Learners observe working lava lamps to understand how they work (included in PDF link).

In this activity, learners will discover what it takes to be a frog. By dressing up like one, learners can visualize how each part of the frog plays an important role in surviving its habitat.

Learners observe and discuss a simple model of a wet scrubber, a device for cleaning industrial air pollution.

In this activity, learners experiment with their voices and noisemakers to understand the connections between vibrations and the sounds created by those vibrations.

This highly visual model demonstrates the atomic theory of matter which states that a gas is made up of tiny particles of atoms that are in constant motion, smashing into each other.

In this chemistry challenge, learners systematically investigate which combination of four solutions produces a deep red color.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners build a Wilberforce Pendulum, a special coupled pendulum in which energy is transferred between two modes of vibration, longitudinal ("bounce') and torsional ("twist"), on a

In this activity, learners make self-assembled polymer spheres.

In this activity and demonstration about electricity and magnetism, learners observe how the current generated when one copper coil swings through a magnetic field starts a second coil swinging.
