7. How does the weather affect us?
The weather affects us in different ways. For example it affects our moods, what we wear, our leisure activities and our mode of travel. The weather also affects the human body and this is mainly done by extreme temperatures and wind.

8. Measuring Weather
The science of studying weather is called meteorology. Weather scientists or meteorologists (people who study the weather), measure temperature, rainfall, humidity, sunshine and cloudiness. They also make predictions and forecasts on how the weather would be in the following days. This is important for giving people advance notice of severe weather.

9. Measuring Temperature
The temperature, or the hotness or coldness of a substance may be measured using a thermometer. A scale on the thermometer can be read to find out what the temperature is. Celsius (◦C) is the most common scale for the thermometers.

10. First Activity Divide the students into groups of four
Provide to each group a thermometer and a beaker
Explain to the students that they are ought to place the thermometer within the beaker and put it near the window
Leave the beaker and the thermometer for 5 minutes

11. Second Activity
Look outside your window. Observe the weather and write the following:
the day
the time
the season
the weather condition
how hot or cold the temperature is according to you (hypothesis)
the actual temperature measured

12. Third Activity – Make it Rain
Provide the following materials for each group: a big jar, warm water, a cold plate, ice cubes and a plastic bag
Perform the following instructions:
place the ice cubes in the plastic bag
pour some warm water into the jar and cover it with the cold plate
Hold for a while the plastic bag with the ice cubes just above the cold plate and observe what happens
Observe and write what happens to the ice cubes
