BLOBS IN A BOTTLE
FOR SCIENCE WE DID AN EXPERIMENT CALLED BLOBS IN A BOTTLE. IT SHOWED THE REACTION BETWEEN OIL, WATER AND ALKA SELTZER TABLETS. WE LEARNT THAT IT WAS LIKE A LAVA LAMP AND THAT WATER IS MORE DENSE THAN OIL AND THEY DON'T MIX TOGETHER. WE LOVED WATCHING THE REACTION. AFTER WE DID THE REAL EXPERIMENT WE WONDERED IF IT WOULD WORK WITH LESS OIL AND MORE WATER. IT STILL WORKED. WE ALSO SHOCK THE CONTAINER TO SEE WHAT HAPPENED.

PLAYING WITH MAGNETS
Today we played with magnets. We started by putting a paperclip in a glass of water. We had to get the paperclip out without getting the magnet wet. We then had some wonderings; like what happens if it is a plastic container or we have leaves, sand or bark in the glass instead of water.
We learnt that we could only save our 'treasure' in water and oil and it did not matter if it was a plastic or glass container. So it only worked when it was a LIQUID in the glass and not a DENSE substance.
We then played with magnets to learn what was around the classroom that was magnetic.
