Tinker crates, kids activity used (RG12, Binfield)

Quite a few of these, photo is not all of them. They are educational science kits for kids aged 7-10 ish. My son has put the kits together and played with them, but as free things that could be played with for a day, with a leaflets that suggest further activities they may be fun? If not I will get rid, just thought I'd check!
Collection from near the old ski slope in bracknell
