Buzzer game

On Tuesday, we made our own buzzer game.

Once we had all the equipment we needed, we began to put the electric circuit that would make the game work together.

We made our wire maze shape and fixed it to a wooden frame.  We also made a wire loop wand to help us play the game.

We then tied the end of the black wire from the battery pack to the end of the wire maze and fixed the other red wire to the bulb. 

When they were secure, we fixed the black wire from the buzzer to the light bulb and then, using a crocodile clip, fixed one end to the wire wand and the other to the bulb.  

The game was then ready to play!  Everyone had great fun.  It was a bit trickier than we thought to get from one end to the other without buzzing!

Electromagnets

This term, we have been learning about electricity and how it works.  We have made different electric circuits and found out about different types of electricity such as static electricity.

Today, we looked at how electricity can make items magnetic.

We wound a length of wire very tightly around a nail.  Once we made sure it was tight, we put a rubber band over a battery and place the bare ends of the wire over each end of the battery.

We took the end of the nail and held it over some paper clips and watched what happened.  The paper clips began to lift up and stick to the end of the nail.  The flow of electricity from the battery, through the wire produced a magnetic force which flowed through the nail, enabling it to pick up the paper clips.  

We all enjoy taking part in the experiment and were fascinated at the result!

Giant Tetrahedron

On Friday afternoon, we joined up with the other P7 classes to work on a Giant Tetrahedron Challenge,  which a few people from Robertsons Construction came in to school to do with us.

We started off working on our own to make individual tetrahedrons.  It was a bit fiddly but we soon got the hang of it and helped each other.

After lunch, we all went to the hall.  We were all unsure of how it was going to be put together!

We went into four groups and were given four of the individual tetrahedrons to put together to make a bigger one.  It took a bit of figuring out but eventually we got there!

We then had to construct an even bigger tetrahedron with these...

And then the final giant tetrahedron!

It was super fun.  Everyone helped each other and showed great team working skills.  It was a shame we had to take it apart!
