Wet stones experiment

Aim: To find the reason for some stones being wet on the river beach.

Focused aim : To investigate the level of wetness on different rocks & how different colours & sizes effects the wetness level of rocks.

Variables:

Control variable: Number of stones

Dependant variable: Amount of moisture

Independent variable: Size & Colour of rocks

Apparatus:

* Digital measuring machine

* Calculator

* Thermometer

Hypothesis:

* Lighter the weight, dryer it is.

* Higher the weight, more wet it is.

Risk Assessment:

* Since condensation level was high in the morning, Stones tend to be wet, Rubber boots are therefore recommended to wear while collection of the stones.

* Since current levels were strong in the morning, not too much close contact with the stream while collecting the rocks is recommended.

Method:

* First we investigated what time to start the project since condensation level is high in the morning & therefore rocks would be wet in the morning.

* Next, we searched
