Fun in the Sun and Shade

 

In this lesson the students will compare temperatures of soil and water in and out of the sun, and recognize that the sun heats the land and water.  By doing this science experiment students will be able to provide evidence showing that the sun is the source of heat and light for Earth.

Standards & Objectives

Learning objectives: 

Students will:

  • Conduct a simple investigation when given directions. 
  • Use observations to construct a reasonable explanation.
  • Know science information specified for their grade level.
  • Explain science concepts and principles using their own words and explanations.
  • Communicate effectively using science language and reasoning.
Essential and guiding questions: 

"What causes land and water to be warmed?

Lesson Variations

Blooms taxonomy level: 
Analyzing
Extension suggestions: 

Look at the effect color has on how hot something gets when placed in the sun. Compare dark soil with light soil or put water in bowls of different colors and/or materials. Does water in a metal bowl get hotter than water in a plastic bowl? Does light‐colored sand stay cooler than dark potting soil?

Use three or four different materials (wood, metal, plastic, etc.) and order them from hottest to coolest after 30 minutes in the sun.

Helpful Hints

For each group:

  • Four white bowls – disposable plastic or Styrofoam bowls work best. White is used so color of the bowl doesn't influence the amount of heat absorbed.
  • soil
  • 2 liter bottle filled with water ‐ room temperature
  • Two thermometers (one used for shade and one used for sun – cleaning off soil before placing in water.)
  • marker
  • Scribe recording sheet (pdf)
  • Recording pages (pdf) for each student Fun in the Sun and Shade.
