Required practicals
Ruler test
drop ruler from curtain height so that the other person can catch whist the ruler being dropped in the same place with the position of the arm in the same place as well
exposure of light
take 3 petry dishes and add mustard seed to all. they should all have the same amount. then adding water to each one same amount again. Then the plants will be place with no light. light at the side and light above
Quadrates test
1) place 1m2 quadrate on the ground at a random point within the first sample area.2) Count all the organisms with in a quadrates. 3) repeat steps 1 and 2. 4) workout the mean number of organisms per quadrate within the first sable area

Waves in air, water and solids
Sound in water and sound in air are both waves that move similarly and can be characterized the same way. Sound waves can travel through any substance, including gases (such as air), liquids (such as water), and solids (such as the seafloor).The amplitude of a wave is related to the amount of energy it carries.

Rate of reaction
the rate of reaction is how fast the reactants are changed into products. one of the slowest is the rusting of iron. other slow reactions include chemical weathering like acid rain damage to limestone buildings.an example of a moderate speed reaction would be the metal magnesium reacting with an acid to produce a gentle stream of bubbles. burning is a fast reaction but explosions are even faster and release lots of gas. explosions reactions are all over in a fraction of a second.
