Core Ideas:

  • 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.

Periods 2, 4, & 6- Learning Activities:

  1. Do Now– Get out your science notebook and add to your Table of Contents- “Molecules in Gas-p.34” (Left Side). Open your notebook to page 34 and head it properly with “Molecules in Gas-Model & Conclusions-12/1/16.” Periods 4 & 6- Complete the Lab Safety Checklist questions #1-5 under After Lab is Completed.
  2. Science Friday– Jump in Jerboas
  3. Review HW– Questions 4 & 5. Tape the Activity handout as a flip page to page 35.
  4. Animation– Particles of a Gas- What did you notice about the molecules of a gas: Do the molecules of a gas have strong or weak attractions? Are the molecules of a gas randomly or orderly arranged? When the molecules of a gas hit each other, do they normally stick together or bounce off?
  5. Model & Conclusion- On page 34 of your science notebook, draw a model of the air molecules in the bottle when it is placed in hot and cold water based on your observations of bubble on top of the bottle. Make a conclusion about whether heating or cooling affects the molecules in a gas and use your observations as support. Observe animation of heating and cooling gas in a bottle to adjust your model & conclusions.

Periods 3 & 7- Learning Activities:

  1. Do Now– Get out your science notebook and open to page 34. What do you see?
  2. Science Friday– Jump in Jerboas
  3. Investigative Phenomenon–Why does a balloon grow when it is heated? Using what you learned about the effect of temperature on the motion of molecules in a gas from the investigation of air in a bottle, create a model to explain what is happening to the balloon in the hot car. (Write-Pair-Share). Observe the animation “Heating Molecules of a Gas” and refine your model. Trim and tape your model as a flip page to p.34.
  4. Comparison of Particles in Liquids, Solids, & Gases-Questions 8 handout
