Question: Describe a time when you used your imagination.
One time I used my imagination was when my teacher was cleaning the blackboard.
At that time, I noticed that a lot of chalk dust was flying all over the classroom, and many students in the front were coughing.
I thought it was bad for us because we did not want to breathe in so much chalk dust.
So I used a wet sheet of tissue and wrapped it around the blackboard eraser.
Because the tissue was wet, the chalk dust did not fly everywhere when the teacher cleaned the blackboard.
After that, no one was coughing, so I thought this idea was quite useful.
However, several hours later, the tissue became dry, and the same problem came back.
When I got home, I designed a new blackboard eraser.
It contained a small bottle of water and a sprayer.
Before cleaning the blackboard, the teacher could spray some water first and then erase the board.
In this way, the water could help absorb the chalk dust.
I think this was a creative idea because I did not just complain about the problem. I tried to use a simple tool to solve it.
