Changing Circuits - Science
As part of our science topic for changing circuits, today we investigated how the amount of bulbs in a circuit affects the brightness of the original bulb that was in the circuit.
Before carrying out the investigation we made predictions about what we thought we would see – some of us had very different opinions!
We found that the more bulbs you added to the circuit, the dimmer the original bulb got. In some cases we even found that the original bulb became so dim you could not tell it was lit, but the second or even third bulb still had light coming from the filament.
We also wanted to know what would happen to the bulbs if we increased the voltage in the circuit – we did this by adding more cells (batteries) to the circuit.
STEM Learning Project Week 3
The focus of our third Bloodhound SSC session, was to build our aluminium wheels. Each member of the group needed to build a wheel. The group then judged which was the best by rolling them along the desk, or testing the strength, or any other creative ideas they come up with. Each child then explained their product to the rest of the group and the group discussed to decide which is best.
The best wheel was then used and a set of four identical wheels was made, with advice and instructions from the winning designer being given throughout the process.
All parts of the wheel were made from aluminium, so the groups also needed to think about creating a hub to hold their wheel securely on the wooden axle.
Safer Internet Use - Visit from West Yorkshire Police
PC Luke Carson visited us on Wednesday 30th January 2019 to talk to us about keeping safe online. He talked a lot about knowing the appropriate age to be using online applications or games and we thought about the meanings behind the different PEGI symbols.
PC Luke Carson also spoke to us about the dangers of sharing our personal information online. He introduced us to a number of different accounts for people and asked whether or not we would be “friends” with them online. From this activity we discovered some of us are far too trusting and it made us think about the people we come in contact with online in gaming and on social networks.
STEM Learning Project Week 2
Today, for our second Bloodhound SSC session, our focus was the test car. Each group needed to:
- Cut out, hole punch, crease, fold and glue their cardboard test cars into shape
- Measure and cut the wooden garden sticks and straws to size.
After we had the body of the car ready each group then needed to think about the best way to test their wheels on their Hakskeen Pan model.
Like a pilot study, they needed to consider different ramp heights and angles, different methods of measuring distance, time taken and observing their car (such as using slow motion video), and how they could then show how they keep these variables the same for each test.
STEM Learning Project
Today we were introduced to a really exciting new project that we are going to be working on in groups for the next 5 weeks. We have been registered to enter a competition to design an all-terrain wheel for the Bloodhound engineering project.
After an introduction to the bloodhound project we thought about the following three research areas:
- the material properties of aluminium
- how BLOODHOUND SSC’s wheels were made
- how articulated wheels are currently being used
After looking at these research areas we had a better idea of the task ahead of us to design some all-terrain wheels for the bloodhound.
Some members of our class have been attending a break dancing afterschool club on a Tuesday evening. As a treat for Keystage 2 the afterschool club and the dance coach Kye performed some of their routines on Tuesday 8th January. There were some amazing moves on show and Kye talked us through the different styles of flips, spins and footsteps that you can use in break dancing.
