4M Clean Water Science - Climate Change, Global Warming, Lab - STEM Toys Educational Gift for Kids & Teens, Girls & Boys

The media could not be loaded. We have tested this product with both the suggested dirty water and water colored with food coloring and it worked on both cases. It should be noted however that the filtering materials are vert small quantities, so using a big amount of water dirt or colors will make it less efficient faster. I would suggest to do the test with small amounts, I think 50 ml is more the enough to demonstrate the principle. For the dyed water I ended up using only 20 ml.My daughter used it for her science project and it was very fun for her to do and she assemble it herself with my guidance to explain the instructions. She is first grade so I do not think it is very challenging bu fun and educating to observe.I added a video of the assembly and the final product and function. I would suggest to use a heavy glass container as a collector as they suggested because it was too flimsy when my daughter used a plastic cup and needed to add a support cup as seen in the end of the video.

Arrived when expected. Easy to assemble. Worked as described. Reasonable price.

I got this for my son who is in the 2nd grade for Christmas. He loves science experiments! It was a BIG hit! He was super excited about it upon unwrapping it. So the surprise/excitement factor was there. When it came down to doing the actual experiment, the instructions were simple and easy to follow. Most everything you need is included & items that are not included are items that most people have on hand at home or in their kitchen(ie: cooking oil, dirt, water). Not only was the water purification experiment enjoyable for my 2nd grader but my kindergartener enjoyed it as well. So, it was a definite "crowd pleaser"(even for the adults involved). Also, there is more than one experiment included. So, you get more "bang for your buck" from that aspect while also getting another activity/experiment to do for another day. Although this was given as a gift, it would also work well for any homeschool, private or public school science curriculum. It is just an all around great buy!

Super fun and easy! Great value for my money. Perfect activity for age range. Kids felt awesome after installation.

Purchased as a gift for the child I babysit. This was a fun STEM project for us on a rainy day, and provided about 3 hours of learning and entertainment.We only managed to get the robot to “go,” for a few seconds but all other attempts were unsuccessful.Some of the pieces were very small, with complex instructions and would likely be difficult for a child under 11 to complete without lots of instruction, assistance, etc. I am 26 and I had to check and re-check to ensure we were doing it correctly.We enjoyed putting it together but we’re disappointed that it didn’t move for more than a few seconds.However, the price was extremely low and it provided us with 3-4 hours of intrigue, entertainment, and learning. With SO much of school being online right now, this was a very solid and inexpensive way to keep the kiddo occupied for a while.

This was a lifesaver for an overdue science project my Son needed to get done for his 4th grade class. The instructions were easy to follow, the science was clear to understand and explain in his report, and he and his Dad had fun building it and testing it out. It worked just as promised and the light is clear to see. It got here fast and was very afforable... just an all around great product! Thank you!

The media could not be loaded. Took my daughter to the coast recently and drove past the windmill farms. She was fascinated and full of questions so we decided to look into a project. Glad we went with this one. Easy to assemble just wish it was a little better quality. Took quite a bit to get the screws tightened.

So educational and fun for all ages! My daughter loved it and she is a teen but she loves science and it was something fun we can do together!
