© Nuffield Foundation 2012 Learning outcomes generate and evaluate scientific arguments present a scientific argument using words and diagrams describe how energy is transferred through a solid conductor from higher to lower temperature apply ideas about energy transfer by thermal conduction in unfamiliar situations.
© Nuffield Foundation 2012 Comparing the two blocks: plastic and metal SimilaritiesDifferences
© Nuffield Foundation 2012 Which ice cube will melt first? Why? Why does ice melt? Why might one ice cube melt more quickly than the other? Predict
© Nuffield Foundation 2012 Describe what you saw happen Are the results what you predicted? Observe
© Nuffield Foundation 2012 Write a scientific explanation of what you saw happening. Use these terms in your explanation: temperature energy conduction Extension: why does metal feel colder to touch than plastic? Explain

© Nuffield Foundation 2012 Further Questions 1.Ice melts more quickly on a metal block than on a plastic one. Would the result be different if ice cubes were placed in a metal box and a plastic box, so that they were completely enclosed? 2.You are supplied with samples of several different materials. How could you adapt this experiment to put them in order, from best conductor to worst conductor? 3.Why do some materials feel warmer to the touch than others?
Bell Ringer SC.7.P.11.4: Observe and describe that heat flows in predictable ways, moving from warmer objects to cooler ones until they reach the same.
HEAT TRANSFER SC.7.P.11.4 Observe and describe that heat flows in predictable ways, moving from warmer objects to cooler ones until they reach the same.
Conduction CONDUCTION is when heat moves through a ________. Metals are better conductors of heat than plastic or wood. This is why… These parts are.
Engineers, what is wrong here?. There are penguins all over the world, not just in Antarctica. The red dots indicate where penguins live. There are penguins.

Conduction Investigation 4, Part 2
Energy as Heat Transfer
- Review the effects of thermal conductivity on thermal energy transfer - Investigate the effects of solid-to-liquid change on thermal energy vs. temperature.
How ‘Heat’ Moves Define “ Heat ”: Heat is the movement of thermal energy from a substance at a higher temperature to another substance at a lower temperature.
Energy Transfer 1. What type of energy transfer occurs when you touch an object? Conduction.
Thermal Energy Heat.
Heating and Cooling. Energy: Heat Transfer Heat is the name for the type of kinetic energy possessed by particles. If something gains a lot of heat energy,
- Review transfer of heat by conduction and convection; class activity on “warmth” of objects - Study the effects of thermal conductivity on temperature.
Heat & Temperature Review. 1. What instrument is used to measure temperature? 1. Barometer 2. Graduated cylinder 3. Thermometer 4. Anemometer.
