  1. SCIENCE 6TH GRADE MRS. MARITES L. DE LUNA November 25-26, 2013 Theme : Suitability of Materials

  2. QUICK QUESTIONS : Monday • 1. Another term for thermal energy is ________. • 2. Heat energy is measured by __________. • 3. The units of temperature are _________ and _________. • 4. ______ is the transfer of energy from objects at a higher temperature to objects at a lower temperature. • 5. Heat may be transferred from low to high temperature as well as vice-versa. (t/f)

  3. QUICK QUESTIONS : Tuesday • 1. A type of material that transfers heat easily is called _________. • 2. When the sky is blue, it is an example of ______ of light. • 3. The transfer of heat energy in which objects touch is called ________. • 4. The three ways to transfer heat are ________, ______ and _______ • 5. The longest wave in the EM is the ________.

  4. Goals : 6.p.3.3(Essential Standards) • By the Tuesday, I can : • 1.Explain the suitability of materials for use in technological design based on a response to heat (to include conduction, expansion, and contraction) and electrical energy (conductors and insulators).

  5. HOMEWORK • Review : Catch a Wave Unit in preparation for your upcoming Benchmark Test before the end of the second quarter. Happy Thanksgiving!

  6. Vocabulary Word : Monday • A combustion engine is a complex machine that burns fuel to produce thermal energy and then uses the energy to do work. • Sentence. An external combustion engine burns fuel externally, or outside the engine.

  7. Vocabulary Word : Tuesday • A refrigerant is a substance, such as Freon™, that has a low boiling point and changes between liquid and gaseous states as it passes through the cooling system. • Sentence. As a liquid, the refrigerant absorbs thermal energy from the cool air inside the refrigerator and changes to a gas.

  8. Review/Preview • Matter can expand and contract based on exposure to or removal from heat. • Materials are chosen based on their response to heat and electrical energy. • Materials can be classified as conductors or insulators.

  9. Vocabulary Word : Thursday • Radio waves are the broad range of electromagnetic waves with the longest wavelengths and lowest frequencies. • Sentence. With their low frequencies, radio waves have the least energy of electromagnetic waves, but they still are extremely useful.

  10. Vocabulary Word : Friday • Gamma rays are the most energetic of all electromagnetic waves. They can pass through most materials, including bones and teeth. • Sentence. A medical device sends gamma rays the site of the cancer, and the rays destroy the cancerous cells.

  13. New Concept : Monday • Thermal energy is transferred through a material by the collisions of atoms within the material. Over time, thermal energy tends to spread out through a material and from one material to another if they are in contact (conduction). Thermal energy can also be transferred by means of currents in air, water, or other fluids (convection).

  14. New concept : Monday –cont. • In addition, some thermal energy in all materials is transformed into light energy and radiated into the environment by electromagnetic waves; that light energy can be transformed back into thermal energy when the electromagnetic waves strike another material. As a result, a material tends to cool down unless some other form of energy is converted to thermal energy in the material.

  15. New Concept : Tuesday • There are some things that we use daily that we want to conduct heat easily. Most of these items are made of materials that conduct heat readily: aluminum, steel, copper. We call these materials thermal conductors. Similarly, there are things that we do not want to conduct heat (pot handles, spatula, cooking utensils) and these items are generally made of materials that limit heat transfer. We call such materials thermal insulators. Expansion joint strips in bridges allow for the bridge to expand in hot weather and not break.

  16. New Concept : Tuesday – cont. • These same joint strips allow for the bridge to contract in cold weather and not break. • Electrical energy also passes through conductors. An electrical conductor is a material through which an electrical current can flow easily. An electrical insulator is a material through which electrical current does not readily flow. Electrical conductors include most metals, while most nonmetallic solids (rubber, glass, porcelain, ceramic) are insulators.

  17. Body Kinesthetic Review! • Conduction, convection, radiation!

  18. INTERESTING IDEA • SCIENCE MAGIC/TRICK

  19. LEARNING CENTERS for the week • 1 – heat racers • 2 – lunchbox activity

  20. Temperature Graph • Temp. Plastic: blue Ceramic : yellow Styrofoam : red Glass : black Time

  21. EXPECTATIONS FOR LEARNING CENTERS • All groups should work cooperatively and harmoniously with each other. • Each member of the group should contribute to the assigned project/experiment. • Answer all analysis questions at the back of the paper • MAKE SURE THAT YOUR GROUP will work AS QUIETLY as possible. You are allowed to communicate but lower your tone so as not to disturb others. • No group hopping. Just stay with your group!

  22. ACTUAL LAB PERFORMANCE

  23. POST LAB DISCUSSION • DISCUSS AND SHARE VARIOUS GROUP RESULTS • ANSWER THE ANALYSIS QUESTIONS

  24. Recording data (Mondays) • Test scores will be distributed. • Test scores will be recorded by both teacher and students. • Students will use a data sheet that will be given by the teacher to track their scores on every test, homework, classwork, laboratory work submitted in class. • Students will learn how to track down their progress in the Science class.

  25. Back Page of Data Sheet ( Line Graph • Example : • S • C • O • R • E • S (y-axis) test # (x-axis)
