Today we will discuss how to measure objects using appropriate tools for comparison. We will then learn how to communicate the precision of our tools through calculations.
Look at the class data for the burning iron lab.
- How did the mass change as your stretched the wool?
- Does this change makes sense? How can you explain this?
- How did the mass change when the wool burned?
- Is this what you expected?
- What could possibly explain this result?
- If you were to do this lab again, how could you improve your results?
- Learn how to appropriately communicate the precision of our measuring tools when we record measurements
- Learn how to round calculations to communicate the precision of our measuring tools
