A statement that sums the important point learned from the experiment.

The Hypothesis as a statement and not a question (if correct)

ReasoningReasoning

Must explicitly tie the claim and the evidence

Should describe the scientific principles (Look in your notes or textbook)

Claim:Claim:

Creating a wide base and a thinner tower creates the tallest tower.

Creating a wide base and a thinner tower creates the tallest tower.

Evidence:Evidence:

Our tower was the tallest tower, 2.5m and had a wide base and narrow tower. Smaller towers (<1m) with narrow bases fell down.

Reasoning:Reasoning:

“If the center of gravity of an object is above the area of support, the object will remain upright.” Page 205 in Conceptual Physics Textbook.

The wider the area of support, the easier it is to balance the object.

The wider the area of support, the easier it is to balance the object.

Errors:Errors:

1. We measured the tower with 3 meters sticks. Measuring is difficult when the object is taller than the measuring device.

2. We didn’t personally measure the width of other towers.
