How can we identify an objet simply by touching it?
Experiment: Sense of touch
Hypotheses: Ask children how they would be able to identify objects simply by touching them. Discuss shapes, textures, materials, size, temperature, etc.
- An opaque bag with drawstrings.
- Many objects with different textures and shapes.
- Pompons, sand paper, coin, modeling dough, crayon, toothbrush, felt,
small car, piece of a plastic bag, marble, eraser, spoon, etc.
- Sit in a circle with your friends.
- Your daycare worker will sit in the center holding a bag filled with familiar objects. She will present the bag to each of you, one at a time.
- When it is your turn, plunge your hand into the bag.
- While your hand is in the bag, try to identify the object you are touching.
- Pull the object out of the bag.
- If you correctly identified the object, place it in the middle of the circle. If you did not identify it correctly, put it back in the bag.
- When all the objects have been identified, sort them by category (rough, smooth, soft, hard, round, pointed, etc.).
Explanation: Your skin is covered with tiny cells which are invisible to the naked eye. These cells send messages to your brain. They help you distinguish the objects you touch. They play a very important role when you need to differentiate something which is pleasant to touch from something which could be dangerous. For example, if you touch a hot stove, the receptive cells in your hand will send your brain a danger signal telling you to remove your hand immediately.
has a Bachelor's Degree in Biological Science. She has worked in a laboratory and tested her knowledge. She has taught Math, Chemistry, and Physics. She has also developed a simplistic and innovative approach designed to introduce young children to scientific experiments, old and new. She created her friend Globule. This character is sometimes red, and sometimes white. He guides little ones through their scientific experiments and discoveries. It is clear to see Angélique is passionate about children and science. Globule's Approach.
