Question:

What is the density of water? Do different amounts of matter (like water) have the same density?

Learning Tasks:

  1. Do Now- Get out your science notebook and add to the Table of Contents- “Density of Water- p.60” (Left Side). Head page 60 properly with “Density of Water-4/5/18.” Get out the procedure and the analysis questions 2-7.
  2. Investigation– Density of Water- Complete following procedure to collect data. Answer Analysis Questions 2-7. Tape the Activity handout (procedure & data table) as flip page to ISN p.61
  3. Model & CER– Review data as a class. Set up ISN p.60. Model water molecules in the different volumes of water (100mL, 50mL, & 25 mL) and write a Claim Evidence Reasoning regarding why density of any size sample of water is the same. Trim and tape analysis questions as flip page to ISN p.60.

Question:

What is the relationship between volume and density for objects of equal mass?

Learning Tasks:

  1. Do Now– Get out your science notebook and add to the Table of Contents- “Effect of Volume- p.58” (Left Side). Head page 58 properly with “Effect of Volume-3/29/18.” Open your science notebook to page 59. Get out your lab activity handout.
  2. Science FridayForecasting Avalanches
  3. Investigation– What is the relationship between volume and density for objects of equal mass?  Complete calculating the densities and identifying the samples using the densities. Answer question 5. Tape the Activity handout as flip page to ISN p.59. Review data as a class. On ISN p.58, model relative size & arrangement of atoms/molecules in plastic & metal cylinders and write a Claim-Evidence-Reasoning (CER) regarding how the volume of cylinders of the same mass affects density.

Question:

What is the relationship between mass and density for objects of equal volume?

Learning Tasks:

  1. Do Now– Copy down today’s homework assignment in your planner. Get out your science notebook and open to pages 56-57. Take out your data table and your graph paper. Work out the following density word problem on the colored paper strip: “Calculate the density of a cube using the following information: Each side is 3 cm long. The mass of the cube is 54 g.
  2. Model & Claim Evidence Reasoning (CER)– On ISN p. 56, draw a model of the relative size and arrangement of atoms/molecules in metal, plastic, & wooden cubes based on your observations of the mass & density of the cubes. Also on ISN p.56, make a claim about the relationship between mass and density for objects of equal volume. Support your claim with evidence and reasoning. Tape data table as flip page to p.57 and tape graph paper as flip page to p.56.

Question:

What is the relationship between mass and density for objects of equal volume?

Learning Tasks:

  1. Do Now– Get out your science notebook and open to pages 56-57. Take out your data table and your graph paper. Work out the following density word problem on the colored paper strip: “Calculate the density of a cube using the following information: Each side is 2 cm long. The mass of the cube is 16g.
  2. Investigation– What is the relationship between mass and density for objects of equal volume? Check data table and complete graph.
  3. Model & Claim Evidence Reasoning (CER)– On ISN p. 56, draw a model of the relative size and arrangement of atoms/molecules in metal, plastic, & wooden cubes based on your observations of the mass & density of the cubes. Also on ISN p.56, make a claim about the relationship between mass and density for objects of equal volume. Support your claim with evidence and reasoning.

Question:

How does temperature affect the particles in a gas?

Learning Tasks:

  1. New Seats!
  2. 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?
  3. Model and Claim/Evidence/Reasoning (CER)– Set up ISN p.44. Draw a model of the air molecules in the bottle when it is placed in hot and cold water based on your observations of the soap bubble on the top of the bottle. Also on ISN p.44, make a claim about whether temperature affects the molecules in a gas like air. Support your claim with evidence and reasoning. Observe animation of heating and cooling gas in a bottle to help your reasoning.
  4. 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. Observe the animation “Heating Molecules of a Gas” and refine your model. Tape your model as a flip page to p.44.
