Plan a reliable community science project
Science - Grade 6-8

A class wants to create a citizen science project about birds seen near the school. Write one testable research question they could investigate.
A testable question should be specific and involve data that people can collect.
A good testable question is: How does the number of birds observed near the school change at different times of day? This question can be answered by collecting observations at set times. - 2
For the research question, How does the amount of litter in a park change after a weekend? identify the independent variable and the dependent variable.
The independent variable is the time period, such as before or after the weekend. The dependent variable is the amount of litter counted or measured in the park. - 3
Explain why a citizen science investigation should use the same data collection method for every volunteer.
Think about fairness and consistency in an experiment.
Using the same data collection method helps make the data more consistent and reliable. If volunteers collect data in different ways, the results may be difficult to compare. - 4
A project asks volunteers to count pollinators visiting flowers for 10 minutes. Name two details that should be included in the instructions so the data are more reliable.
The instructions should tell volunteers exactly what counts as a pollinator and when to start and stop the 10-minute observation. They could also include where to stand, how to record the data, and what to do if they are unsure about an insect. - 5
A student writes this project question: Are streams healthy? Rewrite it as a more specific and testable citizen science question.
Include what will be measured, where it will be measured, or when it will be measured.
A more specific question is: How does the number of macroinvertebrate types found in a stream compare between two sampling locations? This question is better because volunteers can collect and compare data. - 6
A team wants volunteers to measure air temperature around town. List three pieces of information that volunteers should record with each temperature measurement.
Volunteers should record the temperature, the location, and the time of day. They should also record the date and whether the measurement was taken in sun or shade if that matters to the project. - 7
Look at this sample data plan: Volunteers will count ants anywhere they want, for as long as they want, and report the total number. Identify two problems with this plan and explain how to improve them.
Compare what would happen if one person watched for 2 minutes and another watched for 30 minutes.
One problem is that volunteers are observing for different lengths of time, so the counts cannot be compared fairly. Another problem is that locations are not standardized. The plan could improve by using a fixed observation time and having volunteers record or choose specific types of locations. - 8
A citizen science project studies light pollution by asking people to count visible stars. Why is it important to record the weather and moon phase during each observation?
Weather and moon phase can affect how many stars are visible. Clouds, haze, and a bright moon may reduce the number of stars seen, even if light pollution has not changed. - 9
Write a short set of safety rules for volunteers collecting water samples from a local pond or stream.
Include rules that protect both the volunteers and the environment.
Volunteers should stay with a partner, avoid entering deep or fast-moving water, wear gloves if touching water or mud, and wash hands after sampling. They should also follow local rules and avoid disturbing wildlife. - 10
A project needs data from many neighborhoods. Explain one reason citizen scientists can be helpful for this type of investigation.
Citizen scientists can collect data from many places at the same time or over a large area. This gives researchers more information than one small research team could collect alone. - 11
A volunteer reports seeing a rare frog species but does not include a photo, sound recording, location, or date. Explain why the report may be difficult for scientists to use.
Scientific observations should be supported by enough information for someone else to check them.
The report is difficult to verify because it does not include evidence or important details. Scientists need information such as date, location, and a photo or recording to decide whether the observation is accurate. - 12
Create a simple data table layout for a citizen science project that tracks butterflies in a garden. Include at least four column headings.
A useful data table could include Date, Time, Location, Butterfly Species, Number Seen, Weather, and Observer Name. These headings help organize observations so patterns can be found later. - 13
A citizen science project asks volunteers to photograph plants. Explain why the project should include rules about not picking plants or stepping off marked trails.
The rules protect the plants, soil, and nearby habitats from damage. Citizen science should collect useful data while also respecting the environment being studied. - 14
A group collects mosquito data from 5 backyards in one neighborhood and then claims the results describe the whole city. Explain why this conclusion may not be supported.
Think about whether the sample represents the larger area.
The conclusion may not be supported because the sample is too small and comes from only one neighborhood. Other parts of the city may have different conditions, so the group would need data from more locations before making a citywide claim. - 15
Design the outline of a citizen science investigation about one local environmental issue. Include the research question, the data volunteers will collect, one way to keep data reliable, and one safety or ethics rule.
Choose an issue that people in your community can observe directly.
One possible investigation is: How does the amount of litter differ between school walking routes? Volunteers will count and categorize litter along assigned routes. Data will be more reliable if each route is the same length and volunteers use the same categories. A safety rule is that volunteers should not pick up sharp or dangerous objects and should report them to an adult.
