This is my presentation me and my best friend study on a experiment to make worms with worm juice.

Properties of 2 and 3 Dimensional Shapes

We are trying to see the Properties of 2 and 3 Dimensional shapes by playing a game with a partner when you read a test that tells you the vertex of the shape and how many sides the shape has.

Task

Work on this Doc together with a partner.

What 3 ingredients are needed for rust to occur.

Water

Iron

Oxygen from air

Write a brief paragraph explaining the rusting process (why rusting occurs)

Oxygen from air mixes with water then the iron surface of the nail reacts with oxygen mixed in the water. It forms iron oxide. Iron oxide reacts with water it forms hydrated iron oxide-the red stuff we call(rust). This processes continues until the iron is eaten up.

How could you prevent something from rusting?

You  could use zinc to sacrifice itself so the iron doesn't get rusty from the moisture and the oxygen.

Write 3 sentences explaining something new you’ve learned from this reading.

I’ve learnt that you could use zinc to sacrifice itself so the iron doesn't get rusty from the moisture and the oxygen.I learnt that if you boil water and then put oil in the water and put a nail inside the water you can stop a nail from getting rusty.I also learnt that rusting is caused by water and oxygen from the air.
