Fairtrade

We've been helping to make bunting for the Fairtrade challenge. Mrs Rendall has used them to decorate the Green swans board until it's time to send them off to be added to the official bunting string.

Even more rocket fun!

Our latest rocket experiment involved trying out different shapes of rockets to see which ones flew best. This time they were powered by a puff of air.

We made these ones with paper cuts outs and stuck bendy drinking straws on the back. The straws had to be bent so that the air did not go right through.
We flew them by putting them into a wider straw and puffing air into it.
We measured how far they flew.

We realised that it was important to make sure the rockets were powered by puffs of equal strength to make the test fair. Also we had to start at the same point. The rockets were all the same length too but had different shaped wings or bodies.

Here is a short video clip to demonstrate our techniques!

World Book Day

To celebrate our love of reading we had a secret book swap on World book day. We brought in books we had finished, wrapped them and stuck on a label with just one word to describe the book.


There was a good variety of books to swap and it was fun choosing which one to have.

Let's see what I got!

 

We enjoy reading the new books that were added to our library recently.

More rocket experiments!

Today we made rockets with long balloons, straws, tape and fishing line.  It was quite tough to blow the balloons up but we discovered that Casey was an expert! Ross went a bit red when he tried too!

We know that when air comes out of the back of a balloon it shoots forward in the same way that a rocket is propelled. We taped straws to the balloons and threaded some fishing line through so that we could control where they went.
We had to go into the hall to get enough room to fly the rockets.

Not all The rockets worked well however!
We discovered that short bits of straws worked better than long bits.
Can you tell which rockets had shorter bits?
We had great fun!

Rocket propulsion

We have been experimenting with different ways of propelling objects. Our first experiment was with denture cleansing tablets, water and balloons. We discovered that the tablets reacted with water and made a gas which inflated the balloon. This is what happened.

We tried putting a tablet in a film canister with water and putting the lid on. Some reacted quickly but others had a wee while to wait!
