The Build 2018

Week 10: 20th April 2018

Today was the day! We finally went full power today - wow,  it was speedy!

At the start of the seesion, we remembered all our safety rules and made sure that we had all the safety equipment necessary. We set out the slalom course and thought about how we would take the corners in order not to knock any of the cones and this would give us time penalties on race day. We realised that if we went towards the outside of the turns, we would beable to anticipate the next turn and still manage to get through cleanly. 

 

 

It was great to get back into the car after the Easter break and we are now very excited about our confirmed entry into Seaford College on the 3rd June. 


Week 9: 23rd March 2018

At the start of the day, whilst everyone was arriving, Isobel, Beth and Charlie began to finish the paper mache. Once everyone had arrived, we worked as a team to finish the paper mache.

Later on in the session, we rolled out the car to drive it on a slalom course. We had to think about the best way to approach the turns so we did not knock into the cones. We also learnt how to park in a bay.

  

We also worked out that, to be fair, the pusher would be the next driver so it was easy to keep track on who had driven. When everyone had finished driving Isobel and Beth had the responsibility to carry the battery inside.

In the end, the team work helped us get to our classes 5 minutes quicker than normal and with huge smiles on our faces! We rate this session 9 out of 10 because it was successful and fun to do.

Week 8: 16th March 2018

This week, we continued with the paper mache bodywork, which we started last week. Once again, we had to use a lot of wall paper paste and newspaper to make many layers. 

 

Once we had finished that, Maddie and Isobel attached one battery pack to the back of the car and secured it, so that we were able to test drive the car for the first time.

  

After the battery was secured, we took the car outside and had a safely talk. We learnt that we had to stay behind the car and make sure we wore safety equipment when driving: a helmet, overall, gloves and goggles. 

We also learnt that in order for the driver to start, we use a pusher. This is someone who turns the safety key at the back to turn the electrics on and then push the car when the flag waves. The pusher has to push quite hard so that the car can have the best possible start.

Each of us had a go at driving and it was amazing!

Week 7:  9th March 2018

Due to an unseasonable amount of snow last week, GreenPower was unable to take place so we had to work doubly hard this week!

This week, we focussed on the exterior design of the car. We learnt that some materials are composite materials, which means they are made of more than one material, and can often make the materials far stronger. 

The first step was to discuss the designs of the car. We split the group in half, with one group concentrating on measuring and cutting out templates for the front, back and sides of the bodywork.

 

While this was going on, the other group mixed up wallpaper paste and started to create a paper mache side section. We used strips of newspaper and layered these up, in different orientations, using the wallpaper paste.

 

Overall, we stuck at least 9 layers of our panel (35inchs x 17inces in size).

We also thought about how important it was to ensure all of us know about all parts of the build so we ensured that we swapped groups and helped in both activities. 

As we are hoping to test drive the car next week, we also checked all the construction of the car to ensure that it is 100% safe.

Week 6:  23rd February 2018

This week, we achieve an enormous amount. These include: fuses, attached wires, batteries (positive and negative connections), electrical circuits and bolting in the seat belt.

First of all, we discovered the difficulties of attaching the seatbelt because the washers and nuts would not screw in easily; another complication was tightening the nuts and bolts due to the fact that the spanners did not slot into the slots in the frame.

  

Secondly, we acquired the knowledge about the batteries and how every battery has a positive and negative end. We realised that if we swapped the positive and negative connections we could make the car reverse!

 

We realised that fuses are really important to keep us safe as they only allow a certain amount of electricity to flow through. If there is too much electricity in the circuit, the fuse breaks and the circuit is incomplete. Therefore, the car will stop, keeping us safe.

Week 5: 9th February 2018

Today in Greenpower, we were attatching the steering column, so that, when the car is finished, we will be able to steer it. We also added the brakes. We had to take the steering column off a couple of times: once because we couldn't get a screw through to attatch the rods connected to the wheels.

    

Mr Tanton showed us how the brakes work, and how fiddly they are! We have also been thinking of what we could put on the car's design. Next time, we will probably be adding the eletric parts to our car. 


Week 4: 2nd February 2018

Another cracking week at the GreenPower Club.

This week, we have been eagerly awaiting replies from potential sponsors as the letters were sent out last week. Fingers crossed.

Today, we continued to construct the frame of the car, making sure that we tightened every bolt. We didn't just check twice - we checked three times.

   

Once we were sure everything was fixed, we tightened the seat onto the frame and then got to work on the front axle. Now, that was tricky!

    

At first, we thought we could have a quick look at the manual and then remember all the things we needed to do but we soon realised that the manual was our best friend and we had to look carefully at it MANY times.

  

Eventually, we worked it out, making sure the components were all fixed in the right order!


Week 3: 26th January 2018

What a week! We started with lots of different components and finished with something that is almost resembling a car!

We are starting to get really good at reading the instruction manual and understanding the different codes for all the nuts and bolts, which is making the process far quicker.

 

 

It is amazing how much we can get done when we work together. Sometimes we need 3 or 4 people to do one part – someone to hold the parts, someone to fix the bolts and someone to check.

We have realised how important it is to check our work. After all, we wouldn’t want to car to fall apart half way through racing would we!

The time whizzed by and, before we knew it, the session was finished. One of our GreenPower members was heard saying, “This is addictive! I could build all day!”

We reflected upon our day’s work and could not believe the progress we made!


Week 2: 19th January 2018

Another bright and early start, getting to school at 7:20am!

We knew what we had to do this week so we worked as a team to finish the construction of the seat! It was rather tricky as we had to use an Allen key at the same time as using a spanner in order to hold the bolt in place! We also had to remember which way we had to turn the spanner to tighten the bolts!

Lefty – loosey , righty – tighty!

We were so efficient with the assembly of the seat (mainly due to our fantastic team work!) that we were able to then start on the roll bar. A roll bar is really important on a car as it keeps us safe and protects our heads if the car rolls over in a race. This was a rather tricky thing to start so we had to persevere.


Week 1: 12 January 2018

The day has finally come, GreenPower club has started!

It was a first for us to come to school in pitch black (7.30am) but it was all worthwhile! This year there are 8 of us in the club.

During the past few weeks, we were set the task to write persuasive letters in order to seek sponsorship from local companies.

Fingers crossed we will have more information about whether we get some sponsorship from these letters in a few weeks!

Firstly, we thought about what we wanted to get out of the GreenPower club this year and understood the expectations and health and safety that we need to be aware of. After all, we are working with heavy equipment and tools!

Following that, we looked at the building manuals and nuts and bolts (there are thousands of them!) The manual was a little bit like a grown-up Lego manual but we noticed that we will have to look very carefully at the detail so we don’t make mistakes.

It was time to start the build!

We learnt about the different types of equipment: spanner (ring and open ended, adjustable and socket) as well as Allen keys.

We started with the seat so we could get the hang of finding the right nuts, bolts and washers. It was a bit tricky but we managed to start it, ready to finish next week.
