Make a new hypothesis.
Why does my toast fall jelly-side down?
I think it falls jelly-side down because it's heavier on one side. ✓
Hmmm...every time I drop my toast it falls jelly-side down.
It's going to land dry side up if I add less jelly.
I'm going to test my idea by making new toast with less jelly. ✓
So, what happened here? The toast still falls jelly-side down.
My hypothesis is wrong.
X Incorrect.
