Great for the young inventor

The kit is pretty well done and complete. It has several interesting projects and the instruction books contain a lot of background and information.
I wish the box would have been more clear that it required a AA battery as this was a gift. (I found that out in advance from other reviews.)
A minor criticism is that while the books are really informative, they are at times pretty text dense for the target age group. It's fine with some parental help. Again, this is a super minor thing. I'd totally buy this again.

My first grader and I utilized this kit as a mini sesh for a science replacement due to covid 19 school closures. We love it! It has tons of fun experiments that don’t take very long. Yes, it is for older than 1st graders, but it is perfect for us. Wish it had more materials that is in the “needed materials area” such as black cardboard, wood sticks, copper wire and strong wire. It would be even better that way! Also some instructions weren’t very clear, but in knew what we were doing so all is well!

Great for young scientists!

My 8 year old son wants to be a scientist when he grows up and this kit has so many things that he is able to learn and try out for himself! The books that come with this kit not only give directions, but it also explains why and how the results happen. You do need to use some of your own household supplies, like batteries, scissors, yarn, etc, however there are plenty of things to try if you don’t happen to have something available at that moment! My son loves this kit! It was fun for the whole family and we still have so many more of the “experiments” to try!!

Playz Ridiculous Inventions Science Kits for Kids

Reviewed in the United States on September 4, 2019

Verified Purchase

This kit is so fun to do with kids . My 11 yr old daughter enjoyed doing them all with her siblings ages 5 and 8 and was able to complete most without much help. They learned a bunch of things and it helped teach them to follow instructions. Each experiment had most items needed but did require us to find other items not included. Most we had around the house though. The favorite one was electric circuits , they had a blast with it. My daughter is also very much interested in history and she loved the facts about samual morris , it invited a lesson on him . Overall great price for all thats offered and comes in a sturdy box to store everything in when not in use.

Most of the experiments had to be built exclusively by the parent.

Reviewed in the United States on August 28, 2019

Verified Purchase

This did not come with everything needed. As a busy mom I’m always in need of things that come open and go! Several of the things in this kit that are necessary were not included. So I had to hunt them down or we were not able to do the experiment. I also really disliked the need to cut out small things. Some of this kit had perforated items which were nice, but most were hand cut. And they were tiny! This was heavily indeed parental help . So my kids got bored VERY quickly. But when they were finished my kids enjoyed them and we talked about it. But during the process wasn’t fun for them. Ages 3-7-9-11-13. There are lots of experiments which was really good for the price. The paper quality and print was well done and the quality of material was also good. I think overall it’s a quality box. more independent activities, and NO CUTTING would make it great!

Instructions written were very easy to follow. There so many different things you can do with this kit. Their favorite thing my kids life is learning about the positive and the negative and how only positive can go with positive and negative can only go with negative. They love Making The different things from the robot to a rolling c The different things from a robot to a car . When building the inventions it teaches a variety of things from magnets to electric Circuits . My boys want to order another something like because they loved this one so much .It’s a great thing for busy mines and boys.

Neat and educational!

Reviewed in the United States on December 30, 2019

This science kit is pretty neat. It explains the science behind each project. It's a little too much for my 8 year old to follow so I have to help her, but so far it's worked pretty good. I would say it's a little expensive for the amount of stuff that's in the box, but the educational part of it is worth it I guess.

Great for curious minds and kids stuck at home!

Reviewed in the United States on March 21, 2020

Verified Purchase

I bought this as my daughters school is currently closed due to the COVID-19 outbreak across the world. I have been trying to think of different ways to make her school work she is continuing to do a little more fun than just normal studying. We had an interactive (by way of cutting out and sticking pieces down) science book but still required writing and research. This set has now brought the theory to life. When it arrived she even squealed and loved unboxing it all. She has only done a couple of the experiments so far as trying to stretch them out over the next few weeks. Cant wait to see what she learns, as she actually wants to do this. Highly recommend to those parents and kids stuck at home the next few weeks/months.
