This storyboard does not have a description.
We should time how long it takes for a worm to surface after putting water on it.
Instead, let's see how much water it takes for an earthworm to surface.
What about, if there is more water covering an earthworm, then it will surface!?!
Don't forget the 'because' statement!
We'll need potting soil, water, and a graduated cylinder.
I have what you need. Great work Girls!
We thought we'd find the amount of water it takes for an earthworm to surface.
Let's get to work on that chart!
Gracie and Sydney were talking about their science project. They came up with the question: How much water does it take for an earthworm to surface?
The genius girls then started on their hypothesis. They came up with: If there is more water covering an earthworm, then it will surface, because an earthworm must breathe and it has lungs.
Sydney told Mrs. Ward about the idea the girls thought of, while Gracie told the teacher what they would need. Once they got Mrs. Ward's approval, they made a chart.
