Warm-up Day 1 If everything is made of tiny particles, what do you think those particles are doing?

Day 1: Imploding Tanker Car Activity/Assignment Practicum Review Start new unit: Describing, Observing, and Measuring Particle Behavior Observations of imploding tanker Learning Targets Describe how particles move when a substance is in different phases (gas, liquid, solid).

Practicum Review

The amount of space that matter takes up is its ______________ There are 2 main ways we learned to measure volume: VOLUME

WATER DISPLACEMENT 4.8mL 5.6mL Volume = 5.6 – mL

MEASURING LxWxH 2+2+2= 2x3 2x2x2= 2 3

When we do labs, make sure that no one is a bystander. Everyone is responsible for learning. If your lab partner is doing the procedure, follow along and guide to learn the skills that you will be expected to know and use.

What do we know so far about PARTICLES?

This video shows a railcar that has been filled with steam to be cleaned Watch closely … What clues can you find?

What clues did you find?

FREEZE FRAME FREEZE FRAME Now it is time to record your ideas. What about particles? Before the railcar crushed – What was happening inside and outside the railcar? During the crushing – What was happening inside and outside the railcar? After it was crushed – What was happening inside and outside the railcar?

DURING: The rain is falling and the railcar begins to crush BEFORE: The railcar is sealed with steam AFTER: The rain is falling and the railcar sits crushed.

Warm-up Day 2 Think of something that smells really good. How do you think the smell get from that thing to our noses?

Day 2: Diffusion Lab Activity/Assignment Diffusion Lab Learning Targets Define diffusion and show diffusion with a particle diagram. Explain how temperature affects how particles move.

Diffusion Lab Part 1 Draw a diagram that shows how the scent travelled in the room. Do you think someone outside would be able to smell the scent? Why or why not?

Diffusion Lab Part 2 Write your prediction. Draw a particle diagram of the warm and cold water and food coloring.

Warm-up Day 3 (block) Group the items below into 3 groups: Solids, Liquids, and Gases Steam Ice Lemonade Helium in a balloon Balloon Gasoline

Day 3 (block): Phases of Matter Activity/Assignment Thermal Expansion Lab Learning Targets Explain how temperature affects how particles move. Explain how temperature affects the volume of a liquid.

How do you know if something is a solid, liquid, or gas? SOLIDLIQUIDGAS How dense is it? (Density) How flowy is it? (Fluidity) How stiff is it? (Rigidity)

Lab Procedure Fill one flask with 50 ml water (blue food coloring), and the other with 50 ml alcohol (green food coloring). Insert the stoppers into the flasks and adjust the fit until the fluid level is between 0.1 and 0.2mL. Record the starting volume by reading the level of the liquid. Then place the flask apparatus on a hot plate that has been heated to 30 degrees Celsius. At 30 second intervals, record the level of liquid in each flask. On your whiteboard: – Draw a graph of your data – Explain: What happened to the liquid when it was heated? Predict: What are the particles in the liquids DOING as they become more heated?

Talk with your partner: what will happen to the particles as they get heated? What is the glass pipette measuring for us?

Lab Clean-up 1.Turn off the hot plate and unplug it. 2.Pour the water and alcohol back into the appropriate containers (to be re-used). 3.Rinse flasks. 4.Return all materials to the bin. 5.Put bin on front table. 6.Carefully put hot plate on rolling cart. 7.Return to your seat and start on whiteboard.

Day 4: Phases of Matter Activity/Assignment Thermal Expansion Lab (continued) Particle Videos HOMEWORK: Solids, Liquids, Gases Worksheet Learning Targets Describe the movement of particles in the different phases of matter. Explain the relationship between particle movement and volume of a liquid.

Warm-up Day 5 In our Volume of a Heated Liquid lab, what do you think would have eventually happened if there was NO HOLE in the stopper and we kept heating the liquid? Why?

Day 5: Pressure Activity/Assignment Go over solids, liquids and gases worksheet What is pressure? Drawing pressure in a particle diagram Learning Targets Define pressure. Show pressure using a particle diagram.

Warm-up Day 6 When someone says they are under a lot of pressure, what does that mean? How is this different than our scientific definition of pressure?

Day 6: Volume and Pressure Activity/Assignment Volume and Pressure Lab Learning Targets Correctly use tools for measuring the pressure of a gas Explain the relationship between the volume of a gas and pressure in a closed system

Volume and Pressure Lab Research Question: What is the relationship between volume and pressure of a gas in a closed system? In other words, how does volume of gas affect pressure in a closed system?

Conclusion Statements on the EOC Be sure to include the following in your conclusion: Answer the experimental question. Include supporting data from your data table. Explain how these data support your conclusions. Provide a scientific explanation for the trend in the data.

Answer the experimental question. (Was your hypothesis supported or not supported?) We hypothesized ______________________. Our hypothesis was (supported or not supported?) __________________________ by the data.

Include supporting data from your data table. According to the data, when the volume of gas was ______, the pressure of the system was ______. _____________________________________ _____________________________________

Explain how these data support your conclusions. Our data show that as volume _____________, pressure _____________________.

Provide a scientific explanation for the trend in the data. (How can you explain what is happening based on what you know about particles?) _______________________________________ _____________________________________ _____________________________________ _____________________________________

Write a conclusion for this controlled experiment. In your conclusion, be sure to: Answer the experimental question. Including supporting data from your data table. Explain how these data support your conclusions. Provide a scientific explanation for the trend in the data. Example conclusion for this lab: We hypothesized that if we increased the volume in our system, the gas pressure would increase. Our hypothesis was not supported by the data. According to the data, when the volume of gas was 10mL, the pressure of the system was 123kPa. When the volume of gas was 20mL, the pressure of gas in the system was 83kPa. Our data show that as volume increased, pressure decreased. It’s possible that pressure decreased because the particles were not hitting the sides of the syringe as often in a larger container because they had to travel farther.
