Letterbox Lab – Get Moving

Letterbox Lab – Get Moving

We are now onto box six of Letterbox Lab and this one included one of the best things I’ve ever made with the children.

This sixth box is all called ‘Get Moving’ and contains five experiments. It is a little different to the boxes before in that one or two of the experiments aren’t instant – so you do have to wait a little time to see the results.

So, the first experiment saw the children learn about potential energy. I’m not sure they entirely grasped the concept fully on this one but they did enjoy playing with the popper. We quickly moved onto the solar power, which was also about stored energy. We prepared the seeds by placing some wet kitchen roll into a petri dish and sprinkling the seeds over them.

We left our seeds in the dark inside the box for a couple of days and they were amazed to see the quick transformation of them when they re-opened the box (and a discussion about why the top of the box has changed shape as the water was evaporating). We have now left one set of seeds on the window sill in sunlight and the other are back in the box hidden away. It’s a good way to demonstrate just why plants need sunlight.

We promptly moved onto the third experiment, which sees the water move between glasses and is a good way of demonstrating how plants take water from soil – D and E loved this one and I managed to share a couple of videos on my IG stories as we worked through this experiment. We did leave this one set up on the table for about an hour to see how much water would move across – it moved pretty quickly and didn’t take as long as I’d anticipated it might do and the children really enjoyed this one.

Usually, we complete the boxes in one sitting, but this box was so jam-packed with things we actually covered it over a couple of days. The next two Robo Hand and Reach for It were both ones that needed me to do most of the setting up of as they required a bit of cutting out etc, but the effect was worth it. Robo Hand is a great way of demonstrating just how the tendons in your hand work and it prompted lots of conversation between the children and I as well as lots of checking out our hands and observing just how our fingers bent around and what we use to manipulate larger and smaller objects. This was really superb and such a fabulous way of demonstrating the idea to them.

D, in particular, spent a long while examining the hand and seeing how the fingers moved as he pulled on the strings, and then moving his own fingers. It was lovely to see him puzzling over it and then going back to it a few times in the day again. The building of the ‘reach for it’ grabber is a good follow-on and a great way to demonstrate just how complex the range of movement is in the human hand and it’s been fun watching the two children try to grab with it.

This box has prompted so much discussoin between the children and I and I can see we will end up making more of the robo hands at some stage in the future when they’re a little older. They really got to grips with some of the scientific ideas in this box and it was lovely to see them playing and learning.

I was sent this box in exchange for a fair and honest review

    It’s always interesting to see what you are all up to. I could do with a grabber.
