Well, I finally caught up with Ms Zhang today! It’s been a while. I haven’t had her/seen her in quite a while. Whenever I visit the science staff room, she was always gone! So, Luckily I caught up with her today. And she gave me the healthy tick of approval.
I already prepared my method before this, I did it all in advance, I was just unsure before, that’s all. So here is my method, which still needs some improvement, but it’s a start, right?
Equipment:
- 3 sheets of plastic (for this, I used a plastic file sleeve)
- 10 different brands of black nail varnish
- A golf ball.
Method:
1. Draw ten 7cm by 7cm squares on the plastic sleeves. (use a permanent marker pen to draw the squares) Make sure that they are evenly spaced out; leave approximately 3-4cm gaps between each square.
2. Paint a layer of black nail varnish within the 7cm X 7cm square.
3. Repeat step 2 with nine different nail polishes.
4. Leave the nail polish to dry over a 10-24 hour period.
5. Using a ruler, drop the golf ball 3 times (50cm above the ground) onto a painted square.
6. Repeat step 5 with the remaining squares.
7. Measure how much varnish was chipped off. (Use percentages/ratios?)
8. Discuss and analyse the data collected.
Oh, I really hope this is ok for a start? I might make some changes later on. But this is just the basic structure, I guess. I was also thinking, the other day... Maybe I could also test the strengths of the nail polishes if I repeated this experiment, but paint a layer of clear varnish on top... ? I am not entirely sure. I don’t think I should do that, because it would totally change the whole point of the experiment. I hope this is ok for now. I’m off to buy more nail polish.
Oh, and also, if I don’t end up finding enough different brands of black nail polish, I’ll resort to a colour of similar shade... like a dark brown or red. I don’t know, we’ll see!
