A question and a hypothesis is not actually the same even though they seem similar.
A question is what you ask (like what you want to know the answer to).
Example: What would happen if a caterpillar eats grass every other day?
*A question has a question mark "?" at the end ALL the time.
____________________________________________
A hypothesis is similar to a question but a hypothesis is an explanation made from limited evidence. A hypothesis contains an "If...then,...because" statement.
Example: If I place one plant in the sun and the other plant in the shade then, the plant in the sun will grow faster because a plant needs sunlight to perform photosynthesis in order for it to make it's own food since it's a producer.
*Not all hypothesis es need to be long in length but they need to contain the proper variables (like an independent variable).
