The weather chart

1. Temperature: The temperature is usually measured in degrees Celsius (°C) or degrees Fahrenheit (°F).
2. Precipitation: Precipitation, such as rain or snow, is typically measured in millimeters (mm) or inches (in).
3. Wind speed: Wind speed is usually measured in kilometers per hour (km/h) or miles per hour (mph).
4. Pressure: Atmospheric pressure is typically measured in millibars (mb) or inches of mercury (inHg).
5. Humidity: Humidity is usually expressed as a percentage, with 100% indicating saturation (maximum humidity) and 0% indicating no humidity (dry air).
6. Cloud cover: Cloud cover is usually expressed as a percentage, with 100% indicating a completely overcast sky and 0% indicating a clear sky.
7. Visibility: Visibility is typically measured in kilometers (km) or miles (mi).
8. Dew point: The dew point is the temperature at which the air becomes saturated (100% humidity) and dew or frost begins to form. It is usually measured in degrees Celsius (°C) or degrees Fahrenheit (°F).
9. Heat index: The heat index is a measure of how hot it feels when the relative humidity is taken into account. It is calculated using temperature and humidity, and is usually expressed in degrees Celsius (°C) or degrees Fahrenheit (°F).
10. Wind chill: Wind chill is a measure of how cold it feels due to the combination of wind and temperature. It is usually expressed in degrees Celsius (°C) or degrees Fahrenheit (°F).

The weather can change often in a day. These weather changes can be recorded in a chart. Such a chart is called a weather chart. In the next activity, you will make a weather chart.

Preparing a weather chart

Here are the steps you can follow to prepare a weather chart:

1. Choose a location: Decide on the location for which you want to prepare the weather chart. This could be your home, school, or a specific location that you are interested in.
2. Gather data: Collect data on various weather elements such as temperature, precipitation, wind speed, pressure, humidity, cloud cover, visibility, dew point, heat index, and wind chill. You can use a weather station, online sources, or manually observe and record the weather conditions each day.
3. Organize the data: Organize the data in a table or spreadsheet with columns for each weather element and rows for each day.
4. Create the chart: Use a charting tool or software, such as Microsoft Excel or Google Sheets, to create a line chart or bar chart with the weather data. You can also create the chart by hand using graph paper.
5. Label the chart: Add a title to the chart and label the x-axis with the time period (e.g. days, weeks, months) and the y-axis with the units for each weather element.
6. Analyze the data: Look for patterns and trends in the weather data, such as changes in temperature over time or correlations between different weather elements.
7. Share the chart: Share the weather chart with others by printing it out or sharing it electronically. You can also use the chart to create a weather report or presentation.

Materials required

Your science notebook, weather-measuring instruments such as thermometer, wind vane, rain gauge and barometer.

Procedure

1. Observe the weather for one day.
2. Enter your findings into a table such as shown

Weather chart

EVALUATION

Answer these questions

1. Does the sun shine to the same extent throughout the day?
2. Does the temperature remain the same throughout the day?
3. Do the clouds remain the same throughout the day?
4. Does the wind change in speed and direction during the day?
5. Does it rain throughout the day?

Presentation

The topic is presented step by step

Step 1:

The class teacher revises the previous topics

Step 2.

He introduces the new topic

Step 3:

The class teacher allows the pupils to give their own examples and he corrects them when the needs arise

Evaluation :

1. Explain the meaning of weather.
2. Name three factors that affect the weather.
3. Describe the effects of changes in weather factors on the weather.
4. Name three weather-measuring instruments and describe their uses.

Conclusion :

The class teacher wraps up or conclude the lesson by giving out short note to summarize the topic that he or she has just taught.

The class teacher also goes round to make sure that the notes are well copied or well written by the pupils.

He or she does the necessary corrections when and where  the needs arise.
