4M Kidzlabs Lemon Powered Clock, Chemical Electrical Science Lab Experiment - STEM Toys Educational Gift for Kids & Teens, Girls & Boys 12 Count (Pack of 1)

Our son loved this! He played with it for over an hour. He was fascinated at positive vs negative force, as well as how to make different creations with what is in the kit (with no help at 10yrs old). This is one of the cheaper of the gifts and he played with it for a very long time, and was learning while doing it. Great job, KidzLabs.

Fabulous. I put two of my second grade daycare students on it and they assembled it without my help in less than ten minutes, as the diagram was spot-on. Highly recommended.

This is as good a magnet kit as I could easily and affordably find online. It was quickly delivered and worked well for demonstration purposes in my First grade classroom. The coin shaped magnets placed on the axle made for the most exciting demonstration. One magnet levitates due to opposing poles. Lots of oohs and ahhhs, leading to enthusiastic student investigation.

An interesting physics experiment can be done by using the 2 circular magnets and the fishing rod.Use one circular magnet as the base,insert the pole in it,and drop the 2nd circular magnet (hole)onto the rod (making sure that the poles of the 2nd are set (flip?) so that the 2nd magnet is repelled.The 2nd magnet will oscillate a bit and then come into equilibrium (motionless). What has happenedis the repulsive magnetic force just cancels out the attractive gravitational force. Some extras:(1) weighing the 2nd circular magnet will tell you the magnitude of the repulsive magnetic force(2) adding the 2 block magnets to the base - for example-arranged so that they attract each other, the newbase will raise the equilibrium position of the 2nd circular magnet(3) My 7 year old grand son asked why the suspended 2nd magnet was tilted. I told him my guess is thatwe didn't have complete circular symmetry (the block base magnets) or imperfectionsin the magnetic domains(4) by holding the 2nd circular magnetic against the base and then releasing it,it will fly off the rod.Undoubtedly kids will love that (parents no so much)

I have no issue with how this product works. It does exactly what it is supposed to. However, it would have been just as easy for me to use stuff from my house and get directions off of Pinterest. I didn’t realize that before I purchased it. My preschoolers loved it and that is what mattered most. If you do not have wires, an old watch, and nails, this is a great kit for you. If you have stuff laying around, use Pinterest instead.

We bought these for our grandson aged 10. This is a STEM Learn set that includes 25 pieces for a variety of building and learning activities. The magnets are strong and come in a variety of sizes with suggestions on what to build but then let your imagination go and come up with other magnetic ideas. This is a great kit fr the price and get them thinking scientifically through play.

My 8 and 10 year olds have had hours of fun with this kit! It was easy enough for them to complete all of the projects with minimal assistance. The only negative is that the string provided for the fishing pole is very short, was difficult to tie to the proper pieces, and even double tied, came undone easily. Any string, yarn, or real fishing line can be substituted to resolve that small issue. Otherwise, this is a fantastic value, and something that kids can play with over and over again.

Bought this for my 10 year old son, after he fell crazy in love with Snap Circuits. We're homeschoolers, so the link between electricity and magnetism required the purchase of several books and at least one hands-on magnet activity.It came today. He, my 13 year old daughter, and my 49 year old husband :) spent quite awhile exploring, playing, learning. It definitely sparked my son's interest in learning more about magnetism, which means it's accomplished it's primary purpose. They had fun, which is a secondary purpose. My daughter feels it was a bit too simple, but then, the kit is not geared to her age group.The only drawback is that there only 10 projects in the kit. They've already done all of them. In one evening. My son will have lots more fun coming up w/ his own experiments and simply playing, but still. If it cost more but offered more, it would be an even better deal. Though I'd absolutely buy it again. It cost about the same as a movie ticket and offers immeasurably higher value. Start with Snap Circuits, though.
