1 Similarities and differences | Students observe pictures of organs belonging to different organisms, learn how to interpret a phylogenetic tree and guided to conclude common descent using classification, cross-matching, and discussion | C → E I ↔ E C → I | I ↔ E C ↔ E I ↔ C (All) |
2 Mitosis-Meiosis | They collect data from chromosome tabs, create and use model organisms, make predictions, and describe and discuss how the activity is related to theoretical terms, focusing on the analogies | C ↔ E I ↔ C | All |
3 Mutations | They play a Chinese whisperer’ s game, link the activity with ideas through cross-matching, justify the observed differences using theoretical terms | C ↔ E I → C | All |
4 Natural selection | They pretend to be birds competing for seed collection, record and process their data, draw conclusions and describe the phenomenon under study | C → E E → I I ↔ C | All |
5 Genetic drift | They simulate genetic drift using pom-poms, record and analyze data and make predictions | C → E I → E C → I | All |
6 Evolution’ s mechanisms in action | Using a digital simulation, they test given scenarios or make new ones in order to investigate how evolution mechanisms affect population sizes | C → E I → C | All |
