One is on experimental probability. The part designed to teach students the concept was designed and built by sswe903 and he was kind enough to share it with me. After seeing what he has created, and some of the shortcomings I have designed an add on activity to allow the students to use experimental probability to estimate unknown probabilities in game.
The other map is on gravity. One of the upcoming topics I am teaching is Forces, and this includes gravity. As I was discussing this with sswe903 I had a thought, why couldn't we measure gravity in Minecraft. Performing experiments and using our results to discuss real life gravity and some of the limitations of our experiment.
This is the video I recorded talking about these 2 maps. I am really beginning to think that simple maps that focus on a specific concept are the way for me to move forward. Perhaps linking all of these together into a learning sequence is a job for me in the future.
