Water VS. Barrier/Non Barrier
Question:Would a barrier reduce/delay erosion.
Hypothesis:We do think the barrier will reduce erosion.We believe we are right because we have seen beaver dams that have worked
-Popsicle sticks x2
-Stream Table x2
Variable:We will change barrier vs. no barrier
Observe/measure:The amount of erosion of barrier against no barrier.
Same:our observation of erosion.
Conclusion:Our hypothesis was correct because the barrier did slow it down.
Our picture supports information by showing a diagram.the water got slowed down by the Popsicle stick and sand.The less water in the bucket.It made erosion delay.
Why our was correct is the things that we tested showed that because the sand and wood delayed the flow the water.
