I. Project Planning

As we were brainstorming, we came up with many ideas. However, we decided not to use these ideas because they were unrelated to the UN 17 goals, and the one that we wanted to do, which was about the type of roots that can hold the soil together, was already taken by another group. Thus, we decided to go with our initial topic: “Investigation of the centre of mass on balancing toys.” However, as our group was moving on with the drafting of the proposal, we realized that the topic did not have many real-world applications, rendering it useless. Moreover, we could not think of a suitable experiment for the topic. Thus, we finally came up with the topic “Investigation of the angle of light hitting solar panels,” which we’re currently doing.

Our Research Question:

How does the angle of the light source affect the voltage output of the solar panel?

Our Research Hypotheses:

H1: The lower the degree of the light source relative to it being directly above the solar panel, the more voltage output there will be

Our Independent variable:

The independent variable is the angle of the light source

Our Dependent variable:

The dependent variable is the amount of voltage output from the solar panel.

Our Controlled variables:

a) The sampling data should be in a dark room

b) The distance between the light source and the solar panel

c) The duration of each of the readings

d) The intensity of the light from the light source should also be kept the same to allow for correct readings.

e) The light source used should be kept the same

f) The amount of natural light in the room should be kept the same
