Weather Labs is CREST Star accredited! Your students can earn a
CREST SuperStar award. To find out more about, and take part in,
the British Science Association's CREST Star scheme, go to CREST Star
CREST Star Investigators guidelines
To earn your CREST SuperStar award, you need to follow these
The guidelines can be adapted to suit your classroom needs. We
suggest using the forecast 24 hours ahead of your chosen
- Ask the class to decide the location and time slot in which you
will monitor the forecast (you need to leave 24 hours before you
will measure the forecast). The location could be your school, STEM
club or a local green space. Check you know its postcode.
- Divide your class into pairs or small groups. The groups can
measure all the same phenomenon, or they can each measure different
phenomenon. However, each pair or small group should make their own
- Weather Labs allows you to measure temperature, humidity, wind
velocity, wind direction and cloud cover. Will your class have time
to measure all of these or will you have to be selective? Your
class should decide which weather phenomena you wish to measure and
decide the instruments you will use to collect your data. The class
should build their own - have a look at Test the weather
Steps 4-7 are optional. If you decide not to use the
Weather Labs data sheet, go straight to step 8.
- When you have decided which phenomena you will measure and
decided how you will measure them, go to our forecast page - Your
Weather - and enter the location postcode where you'll be
- View the 24 hour forecast.
- Hit "download data sheet" for the time of the forecast you are
going to monitor. This will automatically generate a spreadsheet in
a new tab. The time and location for this weather forecast is
already entered for you, as are the forecast data. Just fill in
your school name.
- Save this spreadsheet to your computer. You can also print it
out if you wish to record data on paper first.
- Make your weather instruments or access the LGFL online
instruments. Carry out your weather observations during the time
slot you have chosen on the forecast. Pupils can work in large
groups or in pairs. If you're using your own weather instruments
groups can make the same instrument and compare the results they
If you have used the Weather Labs data sheet, carry out
step 9-11. If not, go straight to step 12:
- Enter your own data observations in the spaces on the
spreadsheet. Also enter what time you took the observations and
what devices you used.
- The sheet will automatically produce a report and graphs of the
differences between the forecast and your observations.
- When you have finished, save the sheet as an Excel, Open Office
or NeoOffice file.
12. The records you have made are valuable data. With our
partners at Manchester University, we will be studying what they
reveal, and publishing the results on this site. You can send your
saved spreadsheets to firstname.lastname@example.org .
Please name in the format
- Discuss how accurate the weather forecast was. Groups can
produce a picture, short story or write up of their work. Pupils
can discuss their findings with the class, in the school assembly,
or they can post their findings on the school website.
Extension activities for KS1 and 2
Discuss how to make your
measurements valid. What makes some measurements more valid
than others? Ask your pupils to work in pairs. Do measurements
differ between pair groups? Discuss what might cause this.
Discuss who needs and uses weather forecasts. Do weather
forecasts need to be more accurate for some users than others?
