Welcome and Introductions

Introduction activity: Goals/ Outcomes


-Welcome-Reflection on Variables

-Assessment prototype

-Investigation 3: 3 parts

-Investigation 4: 2 parts

-Investigation 5: 3 parts


Quick Write

    • What causes seasons?
  • Focus on Sunshine
    • I’ve heard it said that Dec 21st is the shortest day of the year. Why would someone say that? Is there a longest day of the year?
  • Calculating Hours of Sunlight for Your Location
    • Using the information we just discussed, as a team predict how many hours of sunlight we will have today? Explain your estimate.
    • Given the sunrise and sunset times, develop a strategy to calculate daylight hours
    • Discuss an example
  • Graph and Analyze Daylight Hours for Berkeley
    • Bar vs. Line
  • Reading
    • Wendy and Her Worldwide Weather Watchers, pre/post questions

Discussion Questions

    • Transparency 3
  • Sun-Earth Model
    • Revolve, Rotation, North Star, Hours of Daylight, Equinox, Solstices, Seasons, ellipse, tilt, perihelion, aphelion
  • Reading
    • Seasons (diagram)
  • Multimedia
    • Seasonal Changes (lab notebook pg 9)
  • Assessment
    • Response Sheet-Seasons and Sun
weather and water investigation 3 seasons and sun6

Weather and WaterInvestigation #3Seasons and Sun




    • What kind of weather do you associate with summer? What is it about summer that makes it hotter? What happens to produce more heat?
  • Beam Spreading
    • Flashlight Circles, Beam Spreading (lab notebook pg 13, Globe demonstration
  • Assess Progress
    • Mid-summative Exam 3
  • Self-Assessment
    • Quick Write (part 1), Seasons and Sun (part 2), Mid-summative assessment
    • Review and discuss how their thinking has changed and what they did in class to change their thinking


    • Do you think the surface of the earth affects how hot the air gets? What is an earth material?
  • Earth Materials Investigation
    • Set up the earth materials, discuss predictions (#1-4 temperature questions)
    • Collect data, graph data (within the axes!)
    • Revise thinking, discuss (#5,6 temperature questions)
    • Radiation, Differential Heating
  • Multimedia
    • Heat and Energy Animation
  • Reading
    • Thermometer: A Device to Measure Temperature, pre/post question


    • Why do your feet feel hot on a sidewalk on a hot day?
  • Energy Transfer Challenge
    • Inquiry vs. Semi-guided
    • How did heat transfer from the hot water to the cold water?
  • Explain Conduction/Multimedia
    • Record notes in lab notebook pg 17 (Heat Conduction)
  • Discuss series of Energy Transfers
    • White board flow chart
  • Ask:
    • Did you every reach for a metal spoon that was in a pot of cooking soup? How did the handle get hot when it hasn’t been in the soup or fire?
  • Conduction Investigation
  • Bowtie Pasta Video
  • Reading
    • Heating the Atmosphere, questions following
  • Assess
    • Mid-summative Exam 4

Density demonstration bottles

    • Why do the liquids behave this way?
  • Layering Inquiry
    • I have 4 liquids for you to investigate. The challenge is to layer all four liquids in a section of straw.
    • How is it that some salt solutions can be heavy and some light if they are made with the same materials?
  • Which is heavier gold or feathers?
    • Foam and Beans Demo
    • If both cups are the same size, how can one be heavier?
    • Introduce density
  • Determine density of the salt solutions
  • Assess
    • Response Sheet - Convection
  • Reading
    • Density, post reading questions

Review methods of heat transfer

    • Light, radiant energy, visible light, UV, and infrared, conduction, warmer to cooler
    • Another method for liquids
  • Water Inquiry
    • Challenge: Make layers with plain water of different temperatures
    • Make predictions in lab notebook
    • Successfully layer
    • Observe again after 5 minutes-Why did this happen?
    • Heat the bottom of the vial and explain what is happening
  • Introduce Convection
  • Reading
    • Convection, pre/post questions
  • Assess
    • Collect Layering Hot and Cold Water Sheets


    • If the sun shines on a parking lot, and the blacktop absorbs some of the radiant energy, what might happen to the part of the atmosphere close to the parking lot?
  • Convection Chamber Demonstration
    • Explain set-up and what it is attempting to model
    • Record observations
    • Convection Cell
  • Multimedia
    • Convection animation
  • Assess
    • Collect Convection Chamber sheetfrom the lab notebook
  • Assess
    • Mid-summative Exam 5
