In this lab activity, learners explore how to initiate a density current. Learners measure six flasks with different concentrations of salt and water (colored blue).

In this electrochemistry activity, learners will explore two examples of electroplating.

Learners build a simple one-cell battery and use an ammeter to measure the flow of current.

Learners test solutions of water, sugar, salt, and hydrochloric acid for electrical conductivity. They immerse leads from a lighting device (a battery pack connected to an LED) into each solution.

In this demonstration, cook a cake using the heat produced when the cake batter conducts an electric current.

In this activity, learners create a battery from fruit. This activity helps learners explore electricity, electrochemistry, and series circuits as well as the process of scientific inquiry.

In this activity, learners light an LED with five cents. Learners use two different metals and some sour, salty water to create a cheap battery.

In this activity about chemistry and electricity, learners form a battery by placing their hands onto plates of different metals.
