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, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this very hands-on lesson, learners will investigate dendrochronology (the study of tree rings to answer ecological questions about the recent past) and come up with conclusions as to what possible

In this activity (p.25 of PDF), learners investigate spores. Mushrooms produce millions of spores which are equivalent to the seeds of plants but without the massive food reserves.

This game introduces learners to the scale of the greenhouse gas problem, plus technologies that already exist to dramatically reduce our carbon emissions and prevent climate change.
