Link to my Mystery Model Observations:
Turtle tab. How long they live with infection.
Keep them in the box - heading 180 degrees - bounces directly off edge.
It helps to do the observation first then to look at the code. It helps students make connections and self-assess.
This mystery model could be used very well in using scientific process and using Scientific Talk and Argument. Students work together in small groups, make observations, and claims, then come together as a class to state their claims using evidence. It's a great practice for students to see that, depending on your focus, different claims can be made and they can all be correct. It's great to have them make connections to real world.
