HEAT TRANSFER-CONDUCTION for grade 7 students

for education purpose

1. Hello, Students!

2. ALMIGHTY FATHER, WE PRAISE AND THANK YOU FOR THIS DAY. WATCH OVER US AS WE GO ABOUT OUR WORK AND STUDIES. HELP US IN EVERY WAY SO THAT WE MAY BECOME THE CHILDREN YOU WANT US TO BE. AMEN.

3. MYSTERY BOX CHALLENGE

4. MECHANICS OF THE GAME

5. Pass the box: Students pass the mystery box around while the music is playing. When the music stops, the student holding the box must draw a mystery picture from inside.

6. Answer the question: Each mystery picture is accompanied by a question related to the picture. The student who drew the picture must answer the question aloud to the class.

7. Repeat: Once the student has answered the question, the box is passed around the circle again while the music plays. The process repeats until all picture in the box are drawn.

9. CONDUCTION HEAT TRANSFER

10. COLD HOT

11. Rubric Scoring 95-100 The group was able to demonstrates a clear and accurate understanding of heat transfer through conduction and provides correct answers to all guide questions.

12. Rubric Scoring 90-94 The group was able to demonstrates a good understanding of heat transfer through conduction and provides mostly correct answers to guide questions.

13. Rubric Scoring 85-89 The group was able to demonstrates a basic understanding of heat transfer through conduction and provides some correct answers to guide questions.

14. CAUTION BE CAREFUL WHEN HANDLING HOT OBJECTS TO PREVENT BURNS OR INJURIES

15. CONDUCTION HEAT TRANSFER

16. Conduction is the transfer of heat from a region of high temperature to a region of low temperature through direct physical contact CONDUCTION

17. Conduction is a mode of heat transfer that occurs due to the vibrating and colliding particles of objects that are in direct contact. CONDUCTION

18. The direction of heat transfer in conduction is always from the hotter side to the colder side until both sides reach thermal equilibrium. Heat transfers from a region of higher temperature to a region of lower temperature. COLD HOT

19. Heat flows from hot to cold regions as hotter molecules with higher kinetic energy collide with neighboring molecules, transferring energy.

20. THERMAL CONDUCTIVITY Thermal Conductivity is the ability of materials to conduct heat. The higher the thermal conductivity means that the material is a good conductor of heat

21. Material Conductivity W/m·K (Watts per meter Kelvin) Silver Copper Gold Aluminum Stainless steel Glass Concrete Water at 20°C Rubber Polypropylene Plastic Wood Air at 0°C 429 401 318 237 15 1.7 1.1 0.6 0.16 0.25 0.04 -0.4 0.025 Table 1: List of thermal conductivities of common materials

22. When he touched the alarm clock
