### Sample Learning Goals

This lesson deepens students' understanding of factors affecting the rate of evaporation.

• Pri 5 & 6 SCIENCE (2014) (2014)

### For Teachers

Evaporation (Surface Area, Temperature, Humidity, Presence of Wind) for Primary School

 For a small surface area, the rate of evaporation of water in the container decreases with timehttps://iwant2study.org/ospsgx/index.php/968Direct Link
 For a middle size surface area, the rate of evaporation of water in the container decreases with time linearly as the surface is constanthttps://iwant2study.org/ospsgx/index.php/968Direct Link
 For a large surface area at the beginning, the rate of evaporation of water in the container decreases with time in the blue trailThis implies larger the surface area the shorter the time taken to evaporatehttps://iwant2study.org/ospsgx/index.php/968Direct Link

 For a low temperature, the rate of evaporation of water in the container decreases with time linearly in the red trailhttps://iwant2study.org/ospsgx/index.php/968Direct Link
 For a middle temperature, the rate of evaporation of water in the container decreases with time linearly in the green trailhttps://iwant2study.org/ospsgx/index.php/968Direct Link
 For a high temperature, the rate of evaporation of water in the container decreases with time linearly in the blue trail.This implies higher the surrounding temperature the shorter the time taken to evaporatehttps://iwant2study.org/ospsgx/index.php/968Direct Link
 For a low wind condition, the rate of evaporation of water in the container decreases with time linearly in the red trailhttps://iwant2study.org/ospsgx/index.php/968Direct Link
 For a medium wind condition, the rate of evaporation of water in the container decreases with time linearly in the green trailhttps://iwant2study.org/ospsgx/index.php/968Direct Link
 For a high wind condition, the rate of evaporation of water in the container decreases with time linearly in the blue trailThis implies higher the wind the shorter the time taken to evaporatehttps://iwant2study.org/ospsgx/index.php/968Direct Link

 For a low humidity condition, the rate of evaporation of water in the container decreases with time linearly in the red trailhttps://iwant2study.org/ospsgx/index.php/968Direct Link
 For a medium humidity condition, the rate of evaporation of water in the container decreases with time linearly in the green trailhttps://iwant2study.org/ospsgx/index.php/968Direct Link
 For a high humidity condition, the rate of evaporation of water in the container decreases with time linearly in the blue trailThis implies higher the humidity the longer the time taken to evaporatehttps://iwant2study.org/ospsgx/index.php/968Direct Link

Experiment 1

Change the temperature to 30 ◦c

Click play to see a graph appears

Click store to save the graph at 30 ◦c

Look at the time taken when the amount of water left in the container is zero.

Record the hours the water takes to evaporate.

Change the temperature to 20 ◦c

Record the hours the water takes to evaporate

Study the 2 graphs to compare the rate of evaporation of water.

Which temperature causes the water to evaporate faster?
