STEM toys for toddlers

[IE00]

Hello, anyone have any toy recommendations for kids onto circuits, electricity, magnets? For toddlers so should be simple?

2.5 year old DS loves putting together food processor, blender, hoover, all unplugged of course. His new favourite phrase is "how does it go?". He asked me "where electricity" the other day! To top it off his dad found an old toy that was his which too can build a simple circuit that powers a fan. He figured it out himself. I want to encourage his interest but can't find any toys at his level. Does anyone have any recommendations? Even if it's aimed at age 5 we can do it with him. I've looked on Amazon but a lot of the circuit toys get bad reviews for being flimsy.

The Science Museum website has stuff like this. I've never actually used any of it, but I assume it's decent quality as it's from the science museum. They have an 'Easy Electrical Circuits' set, but it is from 8+, but maybe with supervision and help he could do it. Or there might be other sets, I haven't looked closely for a while!

Things like Duplo/Lego would also be good if he likes putting things together. Lego have sets with working parts too. Again, intended for older kids, but would be ok with help.

There are also set where you have to build stuff with screws (dinosaurs/diggers etc) that are good for kids with this sort of interest.

What might be best is to try and buy the individual components of a circuit from a school supplier. You can get battery packs, wires, light bulbs etc and build your own circuits.

He would probably be ok with a basic electronics circuits kit, might have to be careful about small parts if he still puts things in his mouth.

Duplo, magnetic tiles, marble run (or larger ball run for toddlers) all great stem toys.
Does he like puzzles? That has the same satisfaction of putting together.

We have this and it's been really fun, our version has a little rotor/copter that flies up in the air when it's powered.

Never had this but it looks interesting, perhaps a little old for your one ATM?

Also consider puzzles - there are hundreds of types of games that promote logical and processed thinking.
Think Fun are a very common brand

This is a fun one.

Thanks we are getting the top one!

My DS who is like this got endless hours out of the Bruder crane. He likes to winch things up.
