Most of the wires are only 2 hair-size strands. My 9 yr old mentee had difficulty inserting wire in motor terminal holes. Wires likely to break. A larger solid wire would make threading the motor terminal easier. LED light was missing so we did not make a vinegar battery. Base of battery powered car is very flimsy (we will glue a popsicle stick under it to prevent buckling), but the car worked very well. Solar powered propeller worked very good when sun came out, and any shadow stopped the prop. Good educational experience about power of sun. Solar cell produced 0.56 volts DC in bright sun. Prop would not turn under a kitchen spot light. We had difficulty identifying the large capacitor. A small switch between solar cell & motor would help.
We had a good time Energy Wiz: The Race to Save the Planetgetting started with this kit. Guide book is very helpful listing parts. My mentee has younger brother & sister, so he did not take it home. Followed the warning about small parts.

My son picked this for his 5th grade science project. It was a great kit with instructional book and all supplies needed for the project. We completed the project and it was super easy due to this kit.
Best Deals for ScienceWiz / Energy Experiment Kit
I bought this for my son, 3th grader. He chose it by looking at the box cover. When he received it, it disappoints him. He was expecting the box ingredient would be the same as cover.
The information about physics and solar are good. But my son got bored after a while I explained to him. I think it has too much info for him. Half of the parts look very CHEAP. That is one reason which loses attraction. But the motors and the capacitors are really good. I think it could have been improved to be more attractive to kids.
In summary, it is more like lab experiment kits. If it can be improve to attract young kids like my son. But anyway, the cover needs to be changed. It looks like false advertisement.
Honest reviews on ScienceWiz / Energy Experiment Kit
This product really helped my 10 year old son gain an understanding of circuitry. BEWARE though, the wires do get hot and smoke if they cross or stay hooked up too long. Highly reccomend with some parently supervision.

This is a great kit for teaching young elementary kids about energy. The experiments were fun and we found the instructions easy to follow. The explanations of most scientific concepts were excellent. The writing definitely does emphasize the importance of clean energy and problems of climate change. If you have an anxious child and were hoping to just learn about energy without having to read to them about the horrors of climate change (like mosquitoes with dengue fever) there are probably better kits for you (or just skip a couple of sections). We were a little disappointed to find that our kit was missing a few small items that it said were part of the kit. I contacted the company and was told that those items were no longer included--I guess they did not bother to include an update noting this. Overall though we still loved it an learned a lot from it. The solar cell experiments were a huge hit with my 7 year old!
