How I Use It
I use a number of these in my classroom when simulating a lab experience makes sense. I particularly appreciate the "gizmos" on color addition and subtraction, as well as the "gizmos" on calorimetry. The site has pre-made student lessons that students can work through. I almost always create my own process for the students to work through.
I have found the explorelearning simulations to be an asset to my class. They are well done and allow for a visualization of some science concepts that I could not achieve in a standard lab experience.
