currents. Watch the video below and answer the following questions. Question 1. Convection takes place in: Question 2. Rising air tends to: ✓ ☐ liquids and gases. expand and become warmer. ☐ ☐ solids only. become denser and warmer. ☐ ✓ liquids only. become denser and cooler. ☐ ☐ gases only. expand and become cooler. Practical Activity 1: Convection in a Room Activity: Find out how convection affects temperature in different parts of a house Set up the STELR sustainable test house. You will need the 12V power supply to connect to the heater. The panels you need are: Bottom - Heater First wall - Temperature sensor at bottom of wall Second wall - Temperature sensor at top of wall Ceiling and other walls - Insulation Connect the temperature sensors to the data collection module and answer Question 1 below before turning on the heater. Question 1. Which temperature sensor do you Question 2. Which temperature sensor actually think will record the highest temperature, the recorded the highest temperature? What was one at the top of the house or the one at the the difference in temperature between the top bottom? Explain your answer. and the bottom? Question 3. How did you prediction compare with the actual result?
