Level 4/5 - Scheme of Work Journeys Through Time s1

Science & Discovery(9-11) Term 1- Lesson 5

During the lesson, learners are progressing toward the following learning aims: Content / Activities Resources

Lesson Objectives: To learn the basics of weather and how it is formed Teacher’s Resources Sheet: Stage Plan Overview: Before Lesson: Prep all materials required and make the appropriate photocopies. 1. Different Types of Weather 2. Why does weather exist? Introduction: 3. How is Rain formed?  Inform the students that they will learn about weather. Ask them what they know about weather? Ask them what they know about the weather in Hong Kong? Ask them what a typhoon is like? Activity Sheets:  Show the students Teacher Resource Number 1 – Different Types of Weather (You can make additional copies if you wish) and ask 1. Why Does Weather Exist? them which different types of weather they can see. Questions.  Go through the basics of weather and how it is formed with Teacher Resource Sheet 2 “Why Does Weather Exist” 2. Describe the Weather  Have a class discussion on what you just read and make sure all the students understand to a basic degree 3. Your Own Weather Symbols  Have a look and analyze Teacher Resource 3 - How is Rain formed? 4. The Local Weather 5. Make a Thunderstorm Main Tasks:  Complete Activity Sheet 1- Why Does Weather Exist? Questions. This will see how much they learnt from the reading.

Teacher Resource Worksheet 2

The Earth’s atmosphere is the air that is between the Earth and space. Weather is the condition of the atmosphere, including temperature, moisture, wind, and air pressure. We need special conditions in the atmosphere to live. These conditions are provided by weather, which is produced mainly by the Sun.

To understand weather, first you must learn a little about the Earth’s atmosphere. The atmosphere is made up of nitrogen, oxygen, argon, carbon dioxide and small amounts of other gases. The atmosphere extends about 300 miles from Earth. The further away from the surface of our planet, the thinner it gets until it joins outer space. There are four layers to the atmosphere. The thermosphere is the highest; the mesosphere and stratosphere are in the middle; and the troposphere is the lowest. Weather occurs in the troposphere. The Sun heats the Earth unevenly and affects the atmosphere.

Warm and cool air move and change air pressure. Changes in air pressure create wind. The Sun also makes warm air rise and form clouds. Clouds then provide precipitation such as rain, snow, sleet, or hail. Heat and energy from the sun warm the land and water, further influencing weather conditions. Weather exists because of the effects of the Sun on the Earth’s atmosphere.

MATERIALS:  Clear, plastic container (size of shoebox)  Red food coloring  Ice cubes (if made with blue food coloring then it will work better)  Ice-cube Tray (so will need a fridge to use in the school)

Steps:  Fill the plastic container two-thirds full with lukewarm water  Let the water sit for one minute.  Place a blue ice cube at one end of the plastic container.  Add three drops of red food coloring to the water at the other end of the plastic container.

Watch what happens:

The blue and cold water sinks while the red and warm water rises. This happens because of convection. The blue water represents the cold air mass and the red water represents the warm, unstable air mass. A thunderstorm is caused by unstable air and convection plays an important part. A body of warm air is forced to rise by an approaching cold front therefore thunderstorm’s form www.youtube.com/watch?v=6WH4ks0hxQQ - Depending on if it works or not then you can also show this video.
