How to Read a Thermometer • °C or °F? • For this lab use °F or Fahrenheit. • Room temperature is around 70°Fahrenheit or about 21°Celsius. • Water freezes at 32°Fahrenheit or 0° Celsius. Materials Science: Properties of Matter © 2014 Project Lead The Way, Inc.

Turn Up the Heat • We will use hand warmers to test the different

Turn Up the Heat • We will use hand warmers to test the different materials. • Be careful with the warmers as they can become hot! Materials Science: Properties of Matter © 2014 Project Lead The Way, Inc.

Tips for Success • Use the same size sample for each material you test.

Tips for Success • Use the same size sample for each material you test. • Make sure the material is between the hand warmer and the bulb of thermometer. Material samples: aluminum foil, paper, foam Materials Science: Properties of Matter © 2014 Project Lead The Way, Inc.

Tips for Success • Let thermometer measure the temperature for 2 minutes before you

Tips for Success • Let thermometer measure the temperature for 2 minutes before you record the number. • Use the timer on the tablet to time the 2 minutes. • Let thermometer cool down after each test for at least 30 seconds. • Follow your teacher’s directions to complete Part 1.

Conductors and Insulators • Conductors let heat flow through easily. – Metals like copper

Conductors and Insulators • Conductors let heat flow through easily. – Metals like copper and gold • Stainless steel pots and pans conduct heat easily. Materials Science: Properties of Matter © 2014 Project Lead The Way, Inc.

Conductors and Insulators • Insulators resist the flow of heat. – Wood – Plastic

Conductors and Insulators • Insulators resist the flow of heat. – Wood – Plastic – Oven mitts – Rubber • The plastic handle cover on a pan keeps it cool even if the pan is hot. Materials Science: Properties of Matter © 2014 Project Lead The Way, Inc.

Conductors and Insulators • The colder material absorbs heat from the warmer material. •

Conductors and Insulators • The colder material absorbs heat from the warmer material. • Heat flows to the colder object. Heat flows from the room temperature bowl to the cold ice cream. After a few minutes, the bowl feels as cold as the ice cream. Materials Science: Properties of Matter © 2014 Project Lead The Way, Inc.
