Remember: As long as you act like a scientist when we do science, you will be treated like a scientist and conduct investigations. If not, you get to watch the rest of us do science.
- Gases and liquids are made of molecules or inert atoms that are moving about relative to each other.
- In a liquid, the molecules are constantly in contact with others; in a gas, they are widely spaced except when they happen to collide. In a solid, atoms are closely spaced and may vibrate in position but do not change relative locations.
Learning Activities (Periods 2 & 3):
- Do Now– Get out your science notebook and open it to page 31 and read the Key Question, Problem Statement, Hypothesis, and Experimental Design; On the slip of paper, write 2 things that you’ve learned about water as an example of matter.
- Investigation- Molecules in Motion- Is the speed of molecules in hot water different than in cold water? Read procedure and discuss and add controlled variables to procedure. Review Science Safety Regulations and complete Lab Safety Checklist- Before You Begin. Review Table Group Member Responsibilities. Begin Lab! Complete Lab Safety Checklist– After Lab is Completed.
Complete Lab Questions 1-4
Learning Activities (Periods 4, 6, & 7):
- Do Now-Get out your science notebook and add to your Table of Contents- “Molecules in Motion Experiment -p.31” (Right Side). Head page 31 properly with “Molecules in Motion-Investigation-11/10/16.” Look at your model of the water balloon popping and read your answers for questions 8 & 9 from yesterday’s handout. If you have not already done so, tape it to page 28 as a flip page.
- Driving Questions Summary Table (except period 7)– Complete the Summary Table on pages 26-27 for the Molecules Matter Activity
- Notebook– Set up page 31
- Investigation-Molecules in Motion- Is the speed of molecules in hot water different than in cold water? On page 31, determine a problem statement, hypothesis, and experimental variables for the key question. (Write- Pair- Share)
