话题：

Writing: imagine a scenario or express your opinion
Density
Density refers to how compact something is. What is the density? What thing does it relate to? Why is it important?
This week's topic: They calculated the density... (90-110 words)

Suggestions:
1) building a metal alloy with a certain density
2) the density of ice is less than the density of water
3) density changes as temperature changes
4) population density
5) Instead of writing a scenario, feel free to comment on the story below.
