In this simulation of natural selection, learners use binder clips in three different sizes to represent the diversity of beak sizes in a bird population.

In this activity, leaners will observe the process of natural selection on a population of birds called 'Springbeaks' over four seasons of breeding on an isolated environment called 'Clippy Island.' L

Just like birds, some dinosaurs had air-filled (pneumatic) bones, which made the dinosaurs' skeletons lighter.

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

In this activity, learners count and measure kidney beans to explore natural selection and variation. Learners measure the length of 50-100 beans.

This guided inquiry three-part activity engages learners in thinking about the mechanism of natural selection by encouraging them to formulate questions that can be answered through scientific investi
