Lung Experiment- 4th Class Room 8

Lung Experiment

Equipment- 3 balloons, 3 straws, plastic bottle, scissors, glue and sellotape. (Rubber Glove)

Method

  1. Cut plastic bottle in half using scissors.
  2. Cut straws and glue together.
  3. Secure balloon to end of each straw with tape.
  4. Make hole in lid and put straw through and secure.
  5. Cut other balloon in half and tape to the bottom of bottle.

Result- When we pulled the balloon at the bottom of the bottle it did not work. We replaced it with a rubber glove. When we pulled the glove down the balloons expanded.

Conclusion- When we breathe (inhale) the diaphragm pulls down making the chest expand. This causes air to be sucked into the lungs. When the diaphragm relaxes the air is pushed out of the lungs (exhale).

Signs of Spring! Room 3

We had great fun searching for signs of spring this morning around our beautiful school grounds. We had a checklist to complete with our partner.  We found insects in the bug hotels and a frog splashed in the frog pond. We saw daffodils, crocuses, catkins and snowdrops. We saw birds returning from warmer countries and we even spotted a nest in a large tree.  We were lucky to see a squirrel from our classroom window yesterday that must have awoken from hibernation.
