Amazing Air Resistance

In our last science lesson we learnt about the effects of air resistance.

In groups we created parachutes and launched them out of the window in hope they would protect an egg!

We found that the larger parachutes with a big surface area fell slower, this was because they faced more air resistance which helped to protect the egg.

There were only a few breakages!

Science Morning

We were lucky enough to have an amazing team of people from Colyton Grammar school, in this morning. They were teaching us all about friction. We were apart of some very fun science experiments and got to complete some of our own.

We sat in hover chairs, had a tug of war over a yellow pages, rode skateboards and made our very own mini hover boards! It was a very exciting morning.

They will be back again next term to look at some of the experiments we complete in school.

Science: Forces

This week we have started a new topic in science. We have been looking at forces.

In our first lesson we looked at the force of gravity and learnt that the weight of an object is how hard gravity if pulling down on an object (measured in Newtons) and the mass of an object is how much matter is inside it (measured in g or kg).

Larger objects (like the Earth)  have a greater pull of gravity.

Through an experiment, we found out that the mass of an object is 100x greater than its weight. So 1N = 100g.

In these photos we are using forcemeters to measure the weight and mass of objects around our classroom.
