Athletics day

At school we did athletics day we did high jump, long jump, shot port, discus, 100m sprint and relay.

For high jump you do not need that much speed and you should more focused on the jumping.

With long jump just run as fast as you can and do not do bigger steps at the end it slows you down just run.

Shot put all you need to do is throw with your strong arm.

Discus you use your strong arm and throw it flat of it whould go slower.

For the sprint and relay you just run as fast as you can to win.

I some times brought my PE gear.

When I did it my results were:

High jump: 90 cm

Long jump: 1.85 m

Shot port: 5.64 m

Discus: 13.57m

health work about heart attacks

 Hello here is a slide about heart attacks and all information I know.

dry ice

Hello i am going to talk about dry ice.

Dry ice is Frozen carbon dioxide that is so cold that when you but in hot water the bubble are so cool when they pop the make a cloud of gas and it looks so cool.

Dry ice does not turn into liquid is turn straight into gas and that is called sublimation.

Here is a picture of dry ice and how cold it is.

gravity

 Hello I am doing this blog post to explain about gravity and doing the question that my teacher have given me too do.

Question 1: Is gravity the same on all planets? No because some of the planets are made out of gas and some are so big and some that are so small that smaller planets has low gravity and big planets has a lot of gravity.

Question 2: How does gravity relate to mass? If you don't know what mass means it means how big is something, gravity relate to mass because the size of a plant means the high the gravity so the size of the plant means the different power of the gravity.

Question 3: Calculate 30 kg on the other plants in our solar system. On Jupiter you 30 kg can turn into 70.2 kg and on Mercury it turn into 11.3 kg and if you are on a lower gravity planet your body will full a part. Here is a link to the site were I found this information

Question 4: How would your life be if you were on a different planet with higher gravity or lower gravity? It would be hard to run and swim with higher gravity and with lower gravity it will be hard walk or jump because you will jump really high and it would be easier to climb up stuff and the hard thing is about higher gravity is it will be hard to make shelter because the gravity will crash you shelter. 

Question 5: What would happen if you try to land on Jupiter? If you try you will not hit rocks at all because Jupiter is a gas planet a gas planet when the planet is made out of gas and the gravity is so strong that you space ship can not go up and with the wind on that plane you can not stay straight and the gravity will get stronger when you get closer to the centre and when you get closer to the centre it will get hotter and hotter soon it can get up to 11,000 degrees at the Centre.

about a leaf

 A leaf has a lot of thing they can collect sun light and when the tree mixes water and sun light together it makes sugar but not normal sugar this sugar is food for the trees. Here is a photo of leafs and there parts.

Me and my team mate made this and it taken a bit to draw them.

Sorry about the photo is sideways.

every thing I know about gold mining

All I know about gold mining is they have support pillars holding the mine up and they have tracks for the carts to wheel them up and down the track so they can move the stones and the gold, the people that are mining are wearing a helmet that has a flash light on it and the hat can protect you for any falling rocks for the top of the mine. Some time they get some dynamite and make a big hole for more mining. There are generators that give you power in the mine.

Discrimination mean's when there are a lot of people on a bus going on but he does not let you on because you are a different colour it is like racism.

I am going to make another blog posts but I'm going to have more information to write about.
