Experiment to observe how rate of reaction depends on the surface:

I) Aim:

Prove that the rate of reaction depends on the surface.

II) Hypothesis:

Smaller the particle size is, faster the reaction will be completed; because when things are smaller, they are completed quicker.

III) Materials:

> 4 beakers

> 1 timer

> 1 frizzy tablet

> 1 knife

> 1 thermometers

> 600 ml of water

> lab coat and safety goggles

IV) Method:

* We cut the frizzy tablet in quarters.

* We put 150cm3 of water in a beaker.

* We put the quarter of frizzy tablet in it.

* We time the reaction and we measure the temperature.

* Then we put another 150cm3 of water in a beaker.

* We cut the second quarter in four pieces and then we put it in the beaker.

* We time the reaction and we measure the temperature.

* Then we put another 150cm3 of water in a beaker.

* We cut the third quarter into
