Problems and solutions by Sanaa

Problems we had:
The weather was cloudy, so we couldn’t get a sun light. We used a lamb (solar light) instead sun light.
We couldn’t transform the unit of the light density (LUX) to the unit of energy (watt).
We didn’t do the experiment several times, so we couldn’t determine the accuracy.
We didn’t use the photovoltaic panel that we sat to measure the sun energy.
In order in improve the lab:
Find sunny day to do the experiment, using the photovoltaic panel to measure the sun energy and how it will affect the water.
Do the experiment several times to get accurate value.
