GAS BEHAVIOR
DAY 1
WARM-UP (7 MIN)
In your notebook, always include the date, the lesson title, and do the warm-up task associated to that date.
Task: *Complete the Musical Warm-Up: "What is that?"*
WARM-UP DISCUSSION (3 MIN)
*When you control the volume of a gas, what happens to the pressure?*
LAB: *BOYLE'S LAW* (15 MIN)
In your notebook, always include the date, the lesson title, and do the warm-up task associated to that date. FOR LABS, IF NO SHEET IS PROVIDED, YOU MUST RECORD STEP TITLES AND YOUR ANSWERS IN YOUR SCIENCE NOTEBOOK
Purpose: To help us visualize Boyle's Law.
Materials: Computer, Wifi, A plastic bottle, Balloons, Scissors
Procedure:
STEP 1: UNDERSTANDING BOYLE'S LAW: First, write the vocabulary definitions and key concepts for the lesson. They are located in "THE NOTES" Section of this web page.
STEP 2: BOYLE'S SYRINGE Go to the Boyle's Law Simulation by clicking this link. You may have to download the simulation which is fine. Next, click all the red check boxes in the simulation. Draw the apparatus including the pressure gauge and the molecules moving inside. Play with the top of the syringe and answer the following questions.
When you lower the volume of the syringe, what happens to the pressure?
When you raise the volume of the syringe, what happens to the pressure?
Why does the syringe go back to 50mL when you release it?
STEP 3: HIGHER LEVEL QUESTIONS: This might be tough, but try to answer the questions on the simulation. Write the word "Done" when finished.
STEP 4: Follow the directions in the video at the bottom of this web page. I'll provide the balloons.
THE NOTES: DAY 1 VOCABULARY (10 MIN)
*Write these down in your notebooks!*
Pressure - the force of a gas’ outward push divided by the area of the walls of the container
Boyle’s law - Boyle found that when the pressure of a gas is increased at a constant, the volume decreases. At a fixed temperature and a fixed amount of gas, volume and pressure behave inversely.
Charles’s Law - Charles found that when the temperature of a gas is increased at a constant pressure, its volume increases. When the temperature of a gas is decreased at a constant pressure, its volume decreases.
EVALUATION (10 MIN)
We'll wrap it up here with today's assessment in your learning management system. Feel free to study your notes and/or the videos below. We always recommend viewing the videos the night before the lesson.
TIME TO TRY IT!
TRY THE BOYLE'S LAW EXPERIMENT
In your lab notebook, write the procedure for a 10 year old to follow.
EXPLAIN WHY THIS HAPPENS. FIGURE IT OUT!!!!
