Writing Conclusions Each part should be 1 (maybe 2) sentences
Claim • A statement that sums the important point learned from the experiment. • The Hypothesis as a statement and not a question (if correct)
Which of the following claims are true? • Lightning doesn't strike the same place twice. • Organic chemicals are safe. • Rubber tires protect a car from lightning. • The Earth is closer to the sun in during our summer. • Studies show vaccines cause autism.
Evidence • Data from the lab that supports the claim • Use specific numbers with units • Qualitative observations
Reasoning • Must explicitly tie the claim and the evidence • Should describe the scientific principles (Look in your notes or textbook) • May describe part of the procedure
Errors • State how two or more ways the data could be inaccurate • May be measuring errors (Be specific) • May be something that should have been tested or was tested incorrectly.
Tallest Tower Lab How do you make the tallest tower out of 3 sheets of paper?
Claim: Creating a wide base and a thinner tower creates the tallest tower.
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: “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.
Errors: • We measured the tower with 3 meters sticks. Measuring is difficult when the object is taller than the measuring device. • We didn’t personally measure the width of other towers.
