Glucose + Oxygen --> Carbon Dioxide + Water
1 of 46
What is photosynthesis?
A chemical reaction in plants to create energy
2 of 46
What would happen to the rate of photosynthesis if there was more light?
It would increase
3 of 46
What is transpiration?
The process where water travels up the plant from its roots to leaves.
4 of 46
Why do plants transpire?
To get water from the roots to the leaves for cooling down and for photosynthesis.

What happens when hydrogen and oxygen are mixed?
Water is produced in a chain reaction
14 of 46
What produced when you mix Carbon and Oxygen?
Carbon Dioxide
15 of 46
Name the characteristics of Carbon Monoxide?

16 of 46
what are 3 magnetic materials?
nickel,cobalt and steel
17 of 46
how is a permenant magnet created?
by heating a metal attracted to a magnet then when it has cooled the domains line up.
18 of 46
how is a temporary magnet made?
a metal is attracted to a magnet then the domains line up and it is a temporary magnet.
19 of 46
how can you vary the strength of a electro magnet?
the more volts used the more powerful the magnet.
20 of 46
how is a magnet destroyed?
heated,hit or placed near other magnets
21 of 46

how does sound travel?
vibrating particles
25 of 46
why cant sound travel through a vaccum?
because there is no particles
26 of 46
which state does sound travel fastest through?
a solid
27 of 46
why does lightning come before thunder?
because light travels faster than sound
28 of 46

35 of 46
How does oxygen get into the blood?
The oxygen diffuses across into the blood
36 of 46
How are fossils formed?
A dead organism falls to the ground and covered by sediment, compressed under pressure and heat, bone degrades away and filled with cement-like stuff.
