Is your arm span equal to your height?

Did you know arm span ( or reach ) is approximately equal to height? We tested this out against a wall using chalk to mark reach and then standing next to the wall to see if it matched height. You should measure from finger tip to finger tip and not have a flat hand as in this photo.     We found my 6 year old’s arm span did equal his height and my 4 year old was a little taller than hers.

Z has been learning about plants at school so was very keen to tell his sisters and I about the purpose of the roots, which we could see beautifully when we removed the beans from the pot.   We rehoused the peas and beans into our planters from last year,...

What’s inside our body?

Todays activity wasn’t planned it just happened, which is my favourite way to do things. My girls decided they wanted to draw around each other and me. We’ve done this before to work out how many  DUPLO bricks tall they are. We used the activity as a great opportunity to learn about the body. Once we’d drawn around everyone we talked about who was the biggest ( me ) and who was the littlest ( H ) and then while H and...

Jelly Science – changes of state and colour mixing

Why does Jelly set? Do you know? It is because of a protein called collagen which is found in our bodies. Collagen is made up of three protein fibers wrapped around each other. Jelly contains gelatin, which is made from collagen which comes from animal bones and skin. When the gelatin is heated and mixed with water the protein fibers unravel and come apart, so the jelly from the packet melts. As the jelly cools the fibers coil up...
