3. 3. TRANSITION DOCUMENT GRADE 4 four. Each group of four should have the following materials. A large Styrofoam cup, a metal spoon, a plastic spoon, a small piece of wood (a chopstick works well as does a tongue depressor) and a piece of Styrofoam cut into the same length as the spoons. Students will place an equal amount of butter onto the top of the handle of the spoons and wood/Styrofoam. Students should then place the items inside the cup with the butter end on the outside of the cup. The teacher will then carefully fill the cups three quarters of the way with warm tap water. Students will then observe which of the items has the butter melt first. Explain: • Ask students to explain why some had the butter melt faster than others. Formalize the learning by explaining that the items which allowed the butter to melt first are conductors because allowed the transfer of heat/thermal energy from the water to the location that held the butter. The materials whose butter did not melt or melted more slowly are not good conductors and are called insulators because they inhibited the movement of heat/thermal energy. Further explain that substances have either the ability to facilitate or inhibit energy transfer. Elaborate: • Have students write a brief paragraph explain how heat/thermal conductors and insulators are similar to electrical conductors and insulators.

Ask them students to identify which will light the bulb and which will not and why. Remind them that a circuit must be complete in order to allow the flow of energy. Explore/Explain: • Use pgs. 9-12 (Energy and Electromagnets) Elaborate: • Provide students a variety of wires (conductors) to use in the making of an electromagnet. Ask them to determine which wire will function best. They will write in their journals how they determined one wire was more effective than the other and they will also provide the reasons why they believe a particular wire was most effective (look for references to insulation and conductivity).

Highlight the examples that clearly demonstrate the role that friction plays in stopping motion. Introduce the term friction. Allow students to explore http://www.bbc.co.uk/schools/ks2bitesize/science/p hysical_processes/friction/play.shtml Explore/Explain: • Create groups of 4-5 students. Provide each group with two matchbox cars, measurement tools, thick books and a variety of surfaces to test (wax paper, aluminum foil, carpeting, wood). Ask students to create a test to show which surfaces are most conducive to for allowing the maximum movement of the cars. Students will record their data in their journals, and write a report of their findings to be shared with the class. Engage: • Allow students to explore this site. Discuss the outcomes. http://www.bbc.co.uk/schools/scienceclips/ages/10 _11/forces_action.shtml Explore/Explain: • Ask students to sit in a straight-back armless chair, keeping their back against the back of the chair and your feet flat on the floor. Have them then fold your arms across their chest and while keeping their feet flat and © 2010, TESCCC 08/03/10 page 5 of 6 Column 3 Notes – Red – important note Green – All or part of a lesson already in CSCOPE can be used for the new TEKS.

6. 6. TRANSITION DOCUMENT GRADE 4 their back straight, ask them to try to stand up. Ask why they feel like they are glued to their chair. • Explain that the force they feel is gravity. By sitting in this position, the center of gravity is at the base of the spine. By trying to stand up with your back straight, you prevent the center of gravity from moving to a position above your feet, which would be necessary to stand up. This will help students physically experience the power of gravity. Elaborate: • Allow students to use the following site: http://www.engineeringinteract.org/resources/park worldplot/parkworldplotlink.htm • Monitor and question as students go through the process. They should make a journal entry for each of the part areas they visit. Evaluate: • See Performance Indicator above (The course must have been tested and the collected data must be shared as a part of the final report.) © 2010, TESCCC 08/03/10 page 6 of 6 Column 3 Notes – Red – important note Green – All or part of a lesson already in CSCOPE can be used for the new TEKS.
