Let's change the hose!

Our vegetable patch has a very old hose, with a lot of holes. We decide we have to change it.

We need to calculate...
How many metres of hose do we need for one patch?
270cm x 4
25cm x 2

Then we calculate for the 4 patches, so...

1130cm x 4= 4520 cm

That's the same as 45m and 20cm.

Let's change it!!

We need new hose, rings, measuring tape, pliers and scissors.

Morning eggs

Have you ever tried swimming in the sea? Did you notice that you could float more easily in the open waters than when you're swimming in fresh water or even in a swimming pool? This experiment will help you understand why!
