Sixth class were busy this week designing and making their own electric quiz. They had learned about circuits last week and put that knowledge into practice to make their own quiz. Fourth class had the opportunity to have a go at the quiz!
Make hole in lid and put straw through and secure.
Cut other balloon in half and tape to the bottom of bottle.
Result- When we pulled the balloon at the bottom of the bottle it did not work. We replaced it with a rubber glove. When we pulled the glove down the balloons expanded.
Conclusion- When we breathe (inhale) the diaphragm pulls down making the chest expand. This causes air to be sucked into the lungs. When the diaphragm relaxes the air is pushed out of the lungs (exhale).
For ‘Engineering Week 2019’, we have been learning about different types of engineers and their various roles.
After discovering some really interesting facts, we were tasked with an engineering challenge of our own!
We had to work as an engineer to design and construct a rubber band powered car.
We began by exploring our materials (cardboard, axles, wheels, elastic band, paper clip) and planning our design.
Then we moved onto the construction stage. This involved folding the cardboard into a box shape (also known as a chassis) and fitting the axles through the front and rear holes on the chassis. Next, we had to fit wheels to the end of each axel. Finally, we had to wrap the rubber band around the rear axle and then attach the rubber band to a fixed position on the front axle of the car.
Although we found it rather difficult to fit the rubber bands, we eventually managed to complete the design.
The final part of our challenge required us to test the rubber band car.
To do so ,we hand to wind up the real axle that was attached to the rubber band and then let it go. This caused the car to move forward.
When you wind up the car’s axle you stretch the rubber band and store potential energy. When you release it the rubber band starts to unwind, and the potential energy is converted to kinetic energy as the car is propelled forward.
What a fantastic week we have had here in St Clare’s! We have been busy this week taking part in different activities for European Week of Sport. To finish off the week today, 6th class took on the teachers in tug of war. The teachers definitely need to work on their strength as 6th class beat them 2-1. Congratulations 6th class!
Well done everyone for participating so well in a superb week of sport!
