This is an activity about prediction. How far can you hop in 5 seconds? Could you make it to the door? Across the room? Everyone lines up and tries it.
In this electrochemistry activity, young learners and adult helpers create a battery from a potato to run a clock.
In this activity, learners make an equatorial sundial, which is simple to construct and teaches fundamental astronomical concepts. Learners use the provided template and a straw to build the sundial.
In this activity (on page 12 of the PDF), learners make a sundial (shadow clock) appropriate for their geographic location in the northern hemisphere and use it to tell time.
In this activity, learners explore how the pendulum has been a reliable way to keep time for centuries.
In this activity, learners build a simple mechanism that regulates the "escape" of energy released by a falling weight by portioning it into discrete amounts.
Learners construct one or more of the following kinds of sundials: a shadow plot, a horizontal sundial, and a diptych sundial.
