CONCEPT: Our solar system is composed of many objects which revolve around a star.
CONTENT OBJECTIVE: 3H2.00 To understand the earth-sun-moon relationship
INSTRUCTIONAL OBJECTIVES: The learner will:
TN COMPONENT OF SCIENCE:
BENCHMARK: Current scientific knowledge and future progress are based upon past scientific truths.
The moon moves across the sky. You can see the different phases of the moon. The shape of the moon changes in a cycle that lasts about a month. To explain rotation and revolution, I want _____ and _____ to come up here. _____ , you be the sun. You just stand there shining. _____, you be the earth. Your part is a little more tricky. You have to rotate on your axis. That means you turn slowly round and round, don't stop. This is continuous. While you are rotating you must also revolve around the sun. As you spin you must also move in a circle around the sun. A rotation takes 24 hours. A revolution takes a year. The moon is a satellite of the earth. The moon doesn't really shine at night. It reflects the light of the sun. The moon makes a revolution around the earth every 28 days and it seems to change shape as it revolves.
2. Children are to work in small groups and construct an earth-sun-moon model from different sizes of spheres. Let children demonstrate the movement of the earth using the model which was constructed.
3. Have children observe the position of shadows during morning and afternoon. Go outside early in the morning and have half of the children positioned so their shadow is seen best. Have their partner trace their shadow using chalk. Trade places. Go back to the same place later in the day. Trace the shadows again. Compare the size and length of the shadows. Relate the change in shadow positions to the rotation of the earth and the time required for the shadow to move.
2. OBSERVING AND RECORDING. Have children observe the change of the moon's shape over a period of one month and record the findings on a chart.
3. Field Trip. Take the children on a trip to the local planetarium, if one is available.)
Classroom Connector Two
I have written some of the terms we need to learn to define on the board. Let's read them together.
1. Satellite - a body revolving around a larger body in space
2. Orbit - the path that one moving object follows around another object in space (Draw a path on the board around the sun.)
3. Rotation - movement around a fixed point (Earth going around the sun)
4. Revolution - movement on a fixed point (Earth turning)
Some facts that we need to know which are related to the earth, sun, and moon are:
The earth is our home planet. It gets light and heat from the sun. The earth travels around the sun.
The sun is a star that is closest to the earth. It is a lot bigger than the earth. It gives us heat and light.
The moon travels around the earth. It travels around the earth while the earth moves around the sun. It is smaller than the earth. It gets its light from the sun. The moon is a natural satellite. All of us have heard about the man-made satellites which are used with television and other types of communication. Did you ever think of the moon as being a satellite? (response)
(Terms and facts should be on the board and written out on paper for each student to enhance learning.)
2. Use the basketball for the sun, softball for the earth, ping-pong ball for the moon. Involve three students with each holding one ball. The student with the softball will walk around the basketball, the ping-pong ball will walk around the softball. Discuss the sizes and the orbits.
3. Involve the students in an art project using construction paper circles, large yellow for the sun, medium green for the earth, small white for the moon. Glue the circles onto black construction paper. Suggest that the students trace the orbital path with a white crayon and label each circle. The teacher will monitor by walking around and observing and helping each child.
4. Show filmstrip on Earth, Sun, and Moon.)
2. The is the closest star to earth.
3. We get heat and light from the _____.
4. The travels around the earth.
5. The moon and earth orbit the _____.
Sally Ride became the first United States, female to go into space in June, 1983.
Kathryn Sullivan became the first United States woman to walk in space.
