Science Fair Reflection

For our science fair, it was pretty difficult to choose a question to investigate. Finding just the right one to test and record was a tough decision because there are so many things that you can do, but are hard to record. I’d say the procedure was very helpful because it had all of the steps we had to do, and at times made us think deeper about our hypothesis and evaluation. Without the document, I may have forgotten one of the steps, and I wouldn’t have done as well because the questions were formed so well, that they made me think deeper.

I’d say that when I worked individually in some parts, I didn’t incorporate ideas from my partner, so they weren’t as good in the format of writing, but it would have been the same scientific quality more or less (less). Something we could have done differently is try working individually to improve my scientific language skills more, and trying a different question that can be tested in a much more fair manner. What I mean by fair, is that there aren’t so many problems with the experiment, to the point that they completely change the results by a large amount. There were so many factors in our cup investigation, next time I should try a more testable experiment. Maybe like at what diameter does an aluminium boat sink?

Something I’ve learned about conducting scientific investigations is that you can test many things, but they have to be in controlled areas with the same conditions. If these are not followed, then the experiment is not valuable.

Science – What We Just Did

How does the light bulb in a circuit work?

Before the circuit, is closed, there are already electrons in the wires. When the circuit is closed, the electrons start moving together, at the same time. Electric charges come out of the negative side of the cell/battery, and travel to the light bulb, where the electric energy is transferred to heat and light energy. Then, the charges go back to the battery to recharge their energy.
