I'm going through my physical science notes from my first year of high school. One of our very first labs (if you can call it that) was learning about the properties of matter with Gobstoppers, and step two was to compare the Gobstopper to our pencil or pen. Here's my chart.
Similarities:
1. Both hard
2. You can choke on both of them
3. Both are matter
4. Both inanimate
Differences
1. Gobstopper tasty; pencil not (I assume no one in my group sampled the pencil)
2. One is food; the other is not
3. Gobstopper round; pencil not
4.Gobstopper has no lead (We'll ignore the fact that the 'lead' in pencil isn't really lead)
Then we had to list four properties of the Gobstopper. My list said: Yellow, round, tasty, hard
I amuse myself so.
