In this activity, learners demonstrate the effects of cold-working (strain-hardening) and annealing. Learners discover that these processes change the load that a wire can support.

In this activity, learners create models of ionic compounds and observe the chemical formula of binary molecules they have created.

In this activity, learners determine the elastic and plastic properties of different types of metal wires.

In this activity, learners stain fabrics--on purpose!

In this activity, learners electrically plate zinc onto brass objects.
