Week of 04/11/22 - 04/15/22 (6th Period) by Queen Nikki

You will need your book. You will read chapter 9 on your own and mark the text using the guide on the projector. Read the whole chapter, it is pretty short.

Next, you will watch the videos below (Click on each link) which will play the lab for you. You will use these videos to make your observations and fill out the front of student sheet 9.1.

Once you are done with those steps you will answer the following questions on the back of Student Sheet 9.1 - guiding questions, observations, and analysis questions. The questions can be found in Teams or they will be written on the board as well.

Observations:

Procedure Part A: Soap Bubbles

Complete the procedure and record your observations here.

How can you explain what you observed?

Questions:

Particle Structures:
1. How are particles structured in different states of matter?

Change in state:
1. What would you do if you wanted to cause a change in state, such as melt some ice or boil some water?

2. How do you think adding or removing thermal energy will affect a gas?

Guiding Question:

1. What happens when gas particles are heated or cooled?

Before Activity:

After Activity:

Analysis Questions:

Scientists search for cause-and-effect relationships that help to explain phenomena. One phenomenon you observed in Part A was the expansion (increase in size) or contraction (decrease in size) of a soap film.

a. What cause-and-effect relationships did you observe with the soap film investigation?

b. Use what you know about particles to write an explanation for this relationship.

2. Which explanation do you agree with? Create an argument using evidence from your investigation to support your decision. In both Part A & Part B of this activity, you investigated that effects of temperature on gas particle movement. The following are two possible explanations for the effects you observed:

*The number of air particles inside the test tube (and syringe) increased with an increase in temperature, and the number of air particles decreased with a decrease in temperature.

*The number of air particles inside the test tube (and syringe) stayed the same, but they took up more space when the temperature increased and took up less space when the temperature decreased.

If you don't finish, this will be homework. Be sure to get this done because I will give you a grade for each part (marking the text, student sheet 9.1, and the questions on the back).

Once you finish your work, you may read, work on something else, draw, do a word search, or you may go to this website and explore the games. https://mrnussbaum.com/games/science-games
