Plants don't get tired like people do. We should investigate
Hey! why dose our class plant look tired?
Maybe its tired!
Slide: 2
Exactly. Scientist use questions to figure out what they want to investigate
I have a question! Dose the amount of sunlight a plant gets affect how grows?
That's a great scientific question!
Slide: 3
Correct! You are predicting what you think will happen
I have a hypothesis! I think the plant that gets more sunlight will grow taller
A hypothesis is a testable prediction, right?
Slide: 4
Great! You are changing one variable so you can see what effect sunlight has.
We'll have two plants that are the same type and give them the same amount of water.
Let's test it!
But Plant A gets plenty of sunlight, while Plant B gets very little.
Slide: 5
Scientists collect data so they can see what happened during the experiment.
Plant A is 12 centimeters tall.
Time to measure!
Plant B is 7 centimeters tall.
Let's record the measurements every few days.
Slide: 6
(Ms.G) Excellent! Remember, scientist don't have to be correct every time. If a hypothesis is not supported, scientists use the results to learn something new
Plant A
Plant B
(Ethan) Our hypothesisWas supported by our results!
7cm
12cm
-Plant A grew more than Plant B
(Koris) Our conclusion is that the amount of sunlight affected the plant's growth
Slide: 7
Scientist are rarely finished
I have another question! Dose the amount of soil affect how fast the plant grows?
