Temperature test of colours1

Do white cars usually get hot quicker than black cars?

So we tested it on  a silver can and a black can. How did we do it?  We put hot water into the cans and put the temperature probe in both cans. We had to test the temperature every 5 minutes.

The results

The silver can had a higher temperature than the black can.

Balloons with a candle!2

In science a few weeks ago we decided to find out if a balloon would take longer to pop near a candle

with water in it or just air. In my group (Grace, shiloh, Belinda and I.)We did air first none of us wanted to do it

because we would’ve got a fright so Shiloh was the brave one to do it. She was blocking her ear and holding the balloon at the same time. It only took a few seconds to pop and of cause we all screamed because of the fright.

Next we did the ballon with water and air Shiloh did it once again. It took longer for the balloon with

water to pop. So the one with water to longer to burst.
