Teaching Earth Science for the first time | Posted in Earth and Space Science

I don't remember where I got this (possibly Facebook - or here!) but I use an inflatable globe and throw it out to a student. The student catches it and tells me how many of their fingers are touching water. They then share something about themselves and toss it to another student. Tally up the number of fingers touching water for each student and then calculate the average at the end It should be close to 70%, the amount of the planet's surface covered with water.

I am developing a lesson on speed and how weight can affect it. Does anyone have any materials and/or resources that could help supplement the lesson?

Project-based learning in a geology classroom | Posted in Evaluation and Assessment

Hi Anna --

The February issue of NSTA's Science Scope has the theme of project-based learning. Although this is a middle school journal, I suspect that the activities could be ramped up a bit for high school. There are good articles on co-designing projects with students and managing group work.
