Science Week Rm 26: Playing the Bananas

We had a great time during Science Week.


In our classroom we learned to use how to play the bananas and the bongo pencil case.

We used:

  • The Classroom Computer
  • The Interactive Whiteboard
  • A Makey Makey Circuit Board
  • Bananas
  • Pupils
  • Items from our pencil case

First we connected the bananas to the Makey Makey circuit board and the circuit board to the computer.

We held one wire and touched the bananas to close the circuit and play the bananas.


We also tested items from our pencil case and found out that the wood of a pencil and the nib didn’t work but pencil lead drawn on paper worked. We also found out that plastic, markers, pencil grip and rubber didn’t work, but a paper clip, a metal key-ring, the metal part of a pen did work.


After that, we tested how many people could carry the current in the circuit and play the bongo drums. We held hands and the first and last person in the line held the clips attached to the circuit board. We figured out that it would travel through 32 people and still work.

We had a great time!!

Rm 26: Testing the Fish Tank

Every week we test how the fish are in our fish tank are. We test the water to make sure it is healthy for our fish and plants.

We test the Nitrates, Nitrites, Iron, PH and Ammonia. We also check the temperature. The chemicals in the tests cause a reaction. We wait 5 minutes for the results. It is amazing to see the colour changing as we wait.

We also add nutrients to the aquarium for the fish and plants. This is very good for the fish tank, it keeps the fish healthy and happy. It is very exciting and enjoyable to do the tests. We learn a lot from taking care of our fish and plants. It is good for the environment.
