BODY MOVEMENTS-ACTIVITIES

  1. Place a scale length-wise on your arm so that your elbow is in the centre. Ask your friend to tie the scale and your arm together. Now try to bend your elbow, Are you able to do it?
  1. Roll a strip of paper into a cylinder. Make a small hole in an old rubber or plastic ball (under supervision of teacher) and push the paper cylinder into it as in Fig.8.2 You can also stick the cylinder on the ball. Put the ball in a small bowl. Is the ball rotating freely inside the bowl? Is the paper cylinder also rotating? Now, imagine that the paper cylinder is your arm and the ball is its end. The bowl is like the part of the shoulder to which your arm is joined. The rounded end of one bone fits into the cavity (hollow space) of the other bone .Such a joint allows movements in all directions. Can you name another such joint you can think of, recollecting the body movements we tried at the beginning of this section?
  1. Let us look at the kind of movement allowed by a hinge. Make a cylinder with cardboard or thick chart paper, as shown in Fig. 8.4 in text book. Attach a small pencil to the cylinder by piercing the cylinder rat the centre, as shown. Make a hollow half cylinder from cardboard such that the rolled up cylinder can fit inside it easily. The hollow half cylinder with the rolled up cylinder sitting inside it, allows movement like a hinge. Try to move the rolled up cylinder. How does it move?
  1. Take a deep breathe and hold it for a little while. Feel your chest bones and the back bone by gently pressing the middle of the chest and back at the same time .Count as many ribs (bones of the chest) as possible. Observe and compare with what you feel of the chest bones.

Then place it on a smooth glass plate or any slippery surface. Observe its movement now. Is it different from that on paper? Do you find that the earthworm is able to move easily on a hard slippery surface?
