Graphs of Weather Forecasts
Graphs of Weather Forecasts:
student will be able to interpret data; make and read a line graph, understand
plotting points on an X-Y axis, and round numbers.
Resources: Teacher: newspaper weather page, or local television
stations often put a 4 to 5 day forecast on their Websites. Students:
12" ruler, pencil, red and blue markers or crayons, lined notebook
Teacher Preparation: Make overhead transparency of newspaper weather
forecast or printout of Website forecast, or be prepared to diagram on
- Pick a line on
the notebook paper about 7" from the top as the baseline. Using
the ruler, draw over it for emphasis.
- On the baseline,
measure from the left edge of the paper, putting marks at 3", 4",
5" and 6".
- Draw vertical lines
with the ruler through each of the four marks.
- Under the baseline,
on each of the four vertical lines, write days of the week from the
- Starting at the
baseline and going up, to the left of the 3" line, write temperatures
in five-degree increments for the range of temperature for your climate
at this time (ours, for example would range from 20 degrees/F to 70
- From the overhead
or diagram on the board, plot the high temperatures for the next four
days, rounding to the nearest 5 degrees.
- Using the ruler,
connect the dots with a red marker.
- Repeat for the
low temperatures, using a blue marker.
- Label the red and
blue lines, label the X and Y axes and title the graph.
Use digital indoor/outdoor thermometer to record daily highs and lows
for a daily update; add other variables, such as cloud information; eliminate
the rounding for a more complex and accurate graph.
