Wind Racers: Science

In science, we have been making wind racers. It had to go as far as possible under the power only of a leafblower. We were allowed limited resources including paper, cardboard and tape. We were also supplied a little cart that our racers would be built upon. Lots of other groups came up with regular sail designs, but Robbie (the mastermind of our group) came up with a radical design the consisted of a cardboard back and a whole lot of masking tape. It would have small strips of cardboard around the sides, a longer piece down the middle as a support, and a large piece for the back, and the rest would be covered by tape. It didn't look very good, but we thought it would work reasonably well. It had a large area for the wind to hit and propel it forward, an aerodynamic design to minimize wind resistance and light materials. Lots of people doubted us, but when we came to the actual testing of the racers, we flew. The test was to see how far they got. We chose to go sixth (for whatever reason) out of seven, so we at least got to see how well the others did before ours. Some others tried and did alright but not great. But then when someone went further then everyone's so far, so they did a victory lap. Then it was our turn. We hoped it would make their victories premature. And it did. The so far best was just over 2 metres, ours went and blew it out of the park, 3.1 metres. The last racer didn't get anywhere clos to that. We did another run after that and it went 5 metres! It's fair to say people were jealous. We then got to redesign our racers for another run. We didn't change much apart from putting a little tape edge around the outside of the back. Other groups were adopting large cardboard on the back of theirs like we had done, and so as a back-up plan if theirs somehow became better, we would put lynx spray on the wheels to grease them up and decrease friction. Others weren't happy. But the teacher said it was fair game, if they were going to take our basic design advantage, why not make a new one. We didn't end up going further, eventually going 4 metres, but it was still the best.

I had a lot of fun with this activity and hope I could do more like this in the future.

Thanks for reading my blog, please give feedback that could help my learning

Gymnastics - P.E

In P.E we have been doing gymnastics. It's not my favourite thing but here is my best

Trampoline (mind the annoying idiots that are my friends):

My routine is something on the trampoline. I chose this sequence because it was the first one on the list. I think I have improved on this sequence as before I used to take a long time to do it

Technology and Change

In social stuies we have been doing technology and change. We learnt about the Stone age, the Ancient Egyptians, and the Romans.

Stone age: We learnt about the different ages, the Paleolithic and the Neolithic, the different tools they used, and the cave paintings they made. Then we made our own. Mie was some people praying to an almighty fish lord

Ancient Egyptian: We learnt about what they used to make the pyramids such as sandstone and limestone. We also learnt about hieroglyphs and mummifying. We then made mummies ourselves.

Romans: We learnt about the way that rome was run and all sorts of different thing they invented. Then we made a display about how Julius caesar was assassinated. Then we presented it at an exhibition. 

The exhibition was really cool and I liked all the displays.

Here is a video of everything

Thank you for reading my blog, I had a lot of fun in this unit.

Speeches in english

In English, we have been doing speeches. It was fun, especially when Nathan did his about why Donald Trump is not racist

What was your presentation about?: Why everyone should be excited about the Bathurst 1000 2019 (it's lit)

Which part of your work are you proud of?: The part where I mentioned golden gaytimes

Were there any challenges?: Not really, just writing it I guess

Would you do anything differently next time?: Make it shorter as it was 6 minutes long

Investigating Levers

Aim: To investigate the advantage of using a lever to lift a load

Hypothesis: I think the more you move the pivot point the less load it will carry

Equipment: 30 cm ruler, a pencil, 2 plastic cups, 20 marbles, blue tak

Method: 

1. Tape the two cups to either end of the ruler centred on the 2 cm and 28 cm mark
2. Place the pencil under the ruler at the 15 cm mark. The pencil will act as the pivot point
3. Add 10 marbles to the cup at the zero end of the ruler
4. Add the marbles one by one to the other cup (at the 30 cm end) until the cups are balanced
5. Record how many marbles were needed
6. Move the pencil to the 13 cm mark and repeat steps 4 and 5
7. Move the pencil to the 10 cm mark and repeat steps 4 and 5

Results/Conclusion: The more we moved the pivot point, the fewer marbles were able to be carried

Egyptian Pyramids

The ancient Egyptian pyramids were large stone triangles in the middle of Egypt. They were and still are marvels of engineering. Commonly made of limestone and other stone materials used to form large structures that were the eternal home of the dead pharaohs and nobles. The oldest pyramid in the world is the Pyramid of Djoser. The largest pyramid is the Great Pyramid of Giza at 139 metres tall

In social studies, we made our own pyramids out of Mega Bloks. My group's pyramid was the largest and probably the Great Pyramid of Giza out of the lot.

I had fun with this and hope we can do more with the mega bloks
