The
children in 2nd class become budding scientists in our classroom this week, in
honour of our annual Science Week.
Many
experiments were carried out and discoveries were made!
Egg Floats
Firstly,
we investigated whether an egg would sink or float in normal tap water (It
sank). Then, we added lots of salt to another glass of tap water, to
investigate whether this made any difference. Result: the egg floated in
salty water.
The
children made predictions before the experiment and recorded the results
afterwards.
We
had a chat about the difference between swimming in a lake (fresh water) and
the sea (salt water) - it's easier to float in salt water. The Dead Sea
is the saltiest area of water on Earth, so you can easily float there.
However, it is too salty for any fish or sea creatures to live in!
Here
are some photos of our egg float results - the salt water is on the left
Gummy Bear Experiment:
The next experiment involved observing what happened to Gummy
Bears when they were submerged in 3 different liquids: water / salt water /
vinegar for 2 hours.
Firstly, the children made their predictions
Next, we submerged the gummy bears
After 2 hours, we examined the bears and observed results
We compared the results to a control bear, which had not been
submerged,
We recorded the results: the bear in Vinegar expanded the
most, next was the bear in Water. The
bear in Salt Water did not expand very much.
Skittles
experiment: mixing skittles with water
Step 1: Arrange coloured skittles around the edge of a plate
Step 2: Predict what will happen if they are partially
submerged in warm water
Step 3: Carry out procedure and record results – photos below!
The
children enjoyed the experiments so much that they brought their notes home and
many of them re-created the experiments over the weekend. We hope that
the parents enjoyed the science labs at home!
Design and Make
Children designed
and made a toy, inspired by the story “The Most Marvellous Thing”, in
conjunction with their digital homework through Seesaw. A record of their work is saved in their individual
folders on Seesaw
