This video was easy to follow and very informative. You included key terms in your lesson and got to the point of your lesson. The way you set it up was like reading a lab with equipment required and then step by step instructions for the lab.

Hi Paul,

You did a very good job! I like the music very much, motivating your audio and getting them excited about learning the content through video! I also like the idea of demonstrating the decomposition reaction through hands-on experiment,very cool. A few observations: The "decomposition" didn't seem to be spelled out correctly in the video. In addition, the step-by-step instructions could be strengthen by integrating more texts to effectively enhance video content.

Paul,

I liked your audio at beginning of the video. It grabbed my attention. Also, introducing the materials was a nice way to start. Actually performing the experiment yourself was a strength of the video. Nice job.

Music was perfect! Showing the materials was a great touch, especially since that is part of the scientific method. You spoke clearly and really chose a good demo for this!

Paul, great job, I thought your video was planned and organized.You had all the materials and used the hands-on approach. Good job on the demonsrating the process.

This was a great job. I liked the way you stayed in a lab like format. I also enjoyed how you performed the experiment yourself.

I liked how you set the experiment up, explained it and proceeded to demonstrate it, the music in the beginning I thought was a good idea, you seemed a little unsure of yourself at times.

I liked the experiment. I thought that you explained the process very well. A couple of ideas might be to put the crip notes behind the camera so you will be looking at the camera. Safety glasses would be a good idea. Was there a specific amount of chemicals we should use? overall great job!

Nice job, I liked the music in the beginning of the video because hogh school kids can relate to it. You explained the experiment well and you made it easy to follow

Your step by step instructions were very easy to follow. You got the point of your lesson across very well. Very well done in a step by step perspective. good job

Nice video. I liked the opening music. The information was straight forward and easy to understand. The only negative I noticed was that you looked off camera quite a bit and that was a little distracting.
