MysterystoneScience Experiment for Kids Electricity and Magnetism Kit for Students Stem Kit Physics Lab Basic Circuit Board Kit for Learning Starter

The kit arrived in good condition. There are a lot of things I like about it and I think it's well-designed. The panel meters are gorgeous and big, just as you would want them if you're trying to excite young minds. Overall, the components and wiring technology are well-chosen for letting kids "see" the circuits they're working with. I really like how the bell ringer comes apart so you can use its electromagnet separately. Some components are made a little cheaply, as might be expected at this price point. The knife switches look flimsy but they work fine. The ringer for the bell didn't quite reach the bell, so I had to bend it into shape with pliers. The kit says it comes with 3 3V lamps and 3 2.5V lamps, but there is no way to tell which bulb is for which voltage. One of the bulbs that came with the kit was non-functional. I was surprised that the ammeter, on the 0.6A scale, seems to have a resistance as high as 2 ohms or so. The voltage drop across that resistance can really affect the operation of circuits when the ammeter is inserted.The instructions are pretty reasonable for a lot of the experiments but the level is definitely uneven. If you already understand electricity, you'll easily be able to know what to do and how to explain it, but otherwise in some cases you may be a little mystified. Also, there is a piece with two LEDs in it that is never used in any experiments. I found that one of the LEDs is red (with a forward voltage of about 1.9 volts) and the other is blue (with a forward voltage a little over 3 volts).

Bought for my grandson to help decide what he wants to explore in future schooling.....it will either make him or break him lol. Nice kit and plenty of opportunity to learn!

Yes, it helps if the parent knows that blue LED's have a voltage drop of 4 volts so they will not light up with a single battery cell, but my son, figured it out by himself.

It's only an ok deal for 50 bucks considering what you get. That said, it come with a number of neat devices for a child to wire up. The bell, and open frame motor are favorites of my toddler. The bell is great in that it is NOT a legit bell. I had a real one when I was a kid and it was absolutely deafening. This one is much more pleasant. The storage box is actually usable. If you throw away the internal tray, everything fits without perfect placement. Overall we're happy with it. If you buy some alligator clips as well, it's easy to incorporate random electrical parts from around the house (motors, leds and such).

Great Kit

The kit is great in theory, the booklet and the projects are explained and presented well and in a way that can be understood and practiced by a 10 year old. But there a a few problems that I can't overlook, 1, many of the pieces are labeled in chineese, 2, it includes 4 plastic rods instead of 2 glass rods and 2 plastic rods (which in turn nullifies the 1st lesson in the booklet (not a great first impression)), 3, the hand crank generator continues to slip out of place and causes fingers to scrape on the plastic while turning it.All in all, I love the concept, but I would not purchase this from this vendor again.

I like the modularity of it and the partial assembly required makes it more interactive learning meaning you can dissect it and see what components are needed and why. $50 is a bit on the pricey side but considering the meters that are included and the tangible knowledge that it offers the kids it is worth it absolutely!

Missing parts….i was very disappointed
