This download introduces scientific observations and measurements to introductory chemistry, physical science, or general science students. It contains:
- Powerpoint (.ppt): 11-slide presentation that introduces qualitative and quantitative measurements, and uncertainty in measurement.
- 2 Labs (.doc): Lab 1 gives students practice making observations, and Lab 2 allows them to take a series of measurements.
- Teacher's Guide for Labs (.doc)
This is also available as part of my bundled "Chemistry: Intro to Science Unit Bundle" product.
