Natural Science Unit 2 Laboratory Activity:
Goal: To examine weather phenomena, determine what to measure, and plan a valid scientific weather experiment.
Materials and Equipment:
- Use equipment that you already own
You should do this activity AFTER you complete the web reading. Note that it takes 7 days to do all the observations, so plan ahead!
- Determine a set of observations to make about the weather. These could include cloud type, precipitation, wind speed and direction, temperature,humidity, and/or barometer readings. Use good experimental design! What observations can you make that are repeatable?
- Using only equipment you already have available, decide how you are going to get the information for your observations. You may not use local weather services for this activity: you need to make direct observations. You should not go out and buy a home weather station, either!
- Make your observations for five consecutive days and record any data you feel is useful.
- Organize your data, and predict the weather for the next two days on the basis of your data and what you have learned from the web site.
- Complete your observations of the weather for the final two days.
- Review the example lab report in the Student Survival Guide. Prepare your report. It should include:
- A list of your equipment, including instructions on how to make any equipment that you built yourself.
- An outline of the procedures that you used to make measurements or observations, in enough detail that another student could duplicate your observations.
- A data table, listing your observations by day and time for each type of weather activity that you observed.
- Your predictions for the last two days of your observing period, made at the end of the 5th day.
- An evaluation of the accuracy of your predictions.
- Suggestions for improving your observations and ability to predict weather patterns in your location.
