We did do all of them in just two days. I would read him what science concepts would be learning from the booklet I got from TndrBox along with the directions and he was able to do most of the experiments on his own. Many of the experiments we conducted were at night and the pictures I took didn't come out well. We redid some of them so I could take pictures. Most came out with the same result and some came out better. I am glad we repeated them.
JDaniel took a couple of minutes to get the hang of it, but once he got the paperclip moving he had a great time.
Disclaimer: I was sent a monthly kit for review. My thoughts and opinions about it are my own. When original experiments were done the pictures were too dark to share here. We redid them using green as the theme one morning when the light was better.
