1. Draw and label a picture of you experiment set up.
2. Make a data chart to record temperature differences/changes.
3. Describe the patterns or changes in the temperature data.
4. What can you conclude from you data? Include you claim,
evidence, and reasoning.
Claim: A statement that answers the investigation question
Evidence: Scientific data from investigation or research that is appropriate and sufficient to support the claim.
Reasoning: Scientific principles are cited or stated that link the evidence and claim. Shows why the data supports the claim and why it makes sense.
Write your conclusion on the What We Think Chart.
Evidence: The data shows that after _____ of time the thermometer in the violet read ____, yellow _____, red_____ and Infrared____________. The evidence shows that there is light beyond the red area because there was an increase in temperature in the area beyond the red area.
Reasoning:: Light energy is transformed to heat when it interacts with matter. The increase in temperature outside the red of the visible spectrum is evidence of light converting to heat energy. The addition of heat energy can be inferred from the increase in temperature.
