Focus Question:

How does a lid affect what happens to the liquid in the cup?

Learning Tasks:

  1. Do Now– Get out your ISN and add to the Table of Contents- “Lid Investigation 2” p.33 (Right Side). Head p.33 properly with “Lid Investigation 2- 11/4/19.″
  2. Claim-Evidence-Reasoning (CER)– Review pooled class data & calculate average temperature change for both conditions. The average temperature changes represent what we think would be typical if we ran even more trials under the same conditions. Consider claims supported by data. Write down the Claim that you think was supported by our data on ISNp.30 (writing prompt: “A cup with a lid causes a hot liquid in the cup to drop in temperature less than in a cup without a lid.”) and then use our data as Evidence to support your claim (writing prompt: “The average temperature change for the cups with no lids was ____ and the average temperature change for the cups with lids was ____). Now write a Reason why you think it happened (writing prompt: “Here is the scientific reason that this evidence makes sense with this claim: _____).
  3. Turn and Talk Do you think anything was getting into or out of either of the two systems as the liquid in them was cooling down? How could weighing each of these systems at the start and end of an experiment like our first lid lab help us figure that out?
  4. Plan Investigation– Demonstrate how to use a digital scale. Identify the new dependent variable. Discuss the independent and controlled variables. Modify the procedure on the “Procedure for Measuring Changes in Mass in the Cups.” Work in your previous group to decide which steps of the old procedure should be modified for the new and which should be kept the same. Write your new procedure on the handout.

Lesson Question

How does friction influence the amount of force needed to move an object?

Learning Tasks

  1. Do Now– Copy down your Home Learning tasks in your planner. Get out your science notebook and add to the Table of Contents- “Friction CER p.76 (Left Side). Head page 76 properly with “Friction-Claim Evidence Reasoning-6/3/19.”
  2. Claim Evidence Reasoning (CER)– Make a graph of the friction investigation results on graph paper. Set up ISN p.76 for a CER. Claim: What does the graph show- Evidence (from the data)- Reasoning (connect evidence to the claim). Tape the graph as a flip page to ISN p.76.
  3. Navigation Routine– Looking back- What did we just do? What did we figure out last time? Looking forward- What are our next steps? What is one question we need to address? What direction do we need to pursue?
  4. Driving Question Summary Table– Complete the DQST on ISN pgs. 70-71 for the Friction lab.

ISN’s (science notebooks) due Friday 6/7

Thursday, 4/5/18- A Day

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.

Thursday, 3/29/18- A Day

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.

Wednesday, 3/24/18- A Day- Early Dismissal (Weather)

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.
