To help students better understand the difference between chemical and physical changes, we spent some time using our laptops to further explore both concepts this past Thursday. Students progressed through a number of activities at their own pace to review and exercise their knowledge.
Using Kidblog, my best friend and sharing platform, I made a post with five different links for students to explore. Students who finished before others had fun spending additional time creating chemical bonds through the final link.
Online Activity 1: Compounds and Mixtures
This interactive, created by BBC, begins by allowing students to combine two elements. They are then prompted to try to pull them apart, but will be unable to do so. This interactive activity gives students a clear visual of compounds and chemical reactions, as well as the difference between a mixture and a compound (chemical bond). For my class, this provided a good review on separating mixtures as well, which we already explored thoroughly in a number of labs. This activity ends with a short quiz that provides immediate feedback. I think some of the questions are rather tricky for 5th graders, so I allow students to go on to the next activity without completing it.
Added bonus: My students were thorougly entertained by the voiceover’s accent.
