Compare data from different types of days and come to some conclusions. Form a hypothesis and design and carry out an experiment to test it. Talk about people who farm, deal with water and air pollution, lay asphalt or concrete, work outdoors. Have students explore and research solar energy, what it is and how it works. When something takes in or sucks up something.
Examples are a sponge sucking up water or a surface of the earth taking in heat from the sun.
Hypothesis An assumption or idea about something that we can do experiments or tests on to see if it is true or valid. The luminous body in the sky that the earth rotates around that gives off heat and light.
