Button loves "Get Well Soon" on Cbeebies and so when we asked her what topic she would like to do next, she asked to study the body.
Our first lesson was on blood. Button is really into the t.v show "Get well soon" and very interested with any cuts she receives from falling over. So I thought I'd start with blood. We
first talked about where blood was in her body and how the heart pumped it around her body. We felt her heart pumping and then she drew red lines around her body drawing leading to her
Blood sensory tub
You will need
Red water beads - red blood cells (carry the oxygen around)
White blood cells - ping pong balls, toy golf balls or white marbles (fight off germs, bacteria and viruses)
Platelets- red foam cut into strips (heals cuts)
Plasma- water (carry the blood around the body)
I left her to play with this alone but spoke to her about what each thing did for the body. We went over it a few times as she sucked all the plasma out and then cut the red blood cells up. She explained to me that she was taking blood and making medicine. It was fun to watch and she sat there for about an hour on her own.
We also briefly talked about which food groups were good for your blood (you can leave this bit out but Button has become obsessed with what is good and bad for you. So we took the opportunity to explain a little more about food when talking about each part of the body.) So iron, protein and vitamin c. Found in red meat, green leaves, fruit, cheese etc
We kept things simple for Button, as she's still very young. We focused on the words skeleton, skull and ribs. We read funny bones, which she really enjoyed and used that to make our craft skeleton.
You will need
Ear buds (cut to different sizes)
First we worked together to lay the ear buds to look like a skeleton and then glued them in to place (this craft you don't need the white paint). While doing this we talked about bones, and what
they did. Mostly focusing on the skull and ribs. She enjoyed this and we sung the song from the Funny bones book.
For the second skeleton craft, we painted our hands in white paint and printed them onto the black card. We then stuck the ear buds where we thought we had bones. Button loves painting so she really enjoyed this craft. We then stuck the hand skeleton to the body we drew the week before
Kitchen roll tube
Double sided tape
X ray picture print outs
We wanted to show Button how x-rays work and so decided to make a simple x-ray machine. We also thought it might take the fear factor away should she ever need to have a real x-ray.
We cut a hole the width of the tube in the bottom of the liquitab box. We then pushed the tube through the hole. From then on it was just a case of covering the whole thing with white paper, using double sided tape. An alternative would be to paper machè it.
We then used the x-ray machine to "take x-rays" against a black background. Finally, we took a clear A4 (ish) flat and rectangular tupperwear tub and put a mobile (with the torch switched on) in it. We then put our x-ray print outs on the improvised light box so that the light shined through them like a real x-ray. We discussed what the x-ray was of and what it could help us see in terms of broken bones. It then became a role play game of doctor and patients which Button loved.
This was one of our more scientific lessons, that possibly impressed us slightly more than Button!
1 small coke bottle
1 elastic band
We took a small coke bottle and cut the bottom off. We then attached a balloon to a straw using a loose elastic band and fed the straw up through the neck of the bottle. We used the plasticine to seal the neck and hold the straw in place with the balloon hanging within the bottle. We then took another balloon and tied a knot in the neck. We then cut the balloon at its widest point. The top of the balloon was discarded and the bottom was stretched over the open cavity of the bottle with the tied neck hanging down. The final thing was to blow a tiny bit of air down the straw into the balloon.
Your lung is now ready. The bottom balloon represents a diaphragm. By pulling gently and releasing the tied neck of the balloon it changes the pressure in the cavity of the bottle (the ribs). This causes air to be drawn in and out of the straw which represents the windpipe. This in turn causes the lung (the intact balloon) to inflate and deflate a little and so illustrate how we breathe. Easily made but visually very effective!
