Lab- Observing Particulates (tiny particles suspended in the air, usually associated with pollution)
Part 1- Wednesday, Oct. 11 Part 2- Wednesday, Oct. 25

2. 1- Focus Question
If we collect particulates around school (covered and uncovered), how will the types and number of particles in the different locations compare?

3. 3- Materials
2 name badge stickers (8.5cm x 6cm) 2 index cards (size 20cm x 12.5cm) 2 rulers 2 paisr of scissors 1 sharpie 1 piece wax paper (cover)

4. 3- Procedure Day 1 Procedure Gather materials
Use ruler to draw a rectangle 8cm by 5cm in center of each index card
Use scissors to cut rectangles from cards
Use marking pen to write your group name and class period near the edge of each card

5. 3- Procedure
5. Label the first card “uncovered” 6. Label the second card “covered” 7. Remove name tag from backing so that sticky side is exposed 8. Adhere sticker to the index card so that the sticky side shows through the rectangle hole in the center of the card 9. Place cards in location that matches label (either uncovered or covered) 10. Allow cards to remain undisturbed for 2 weeks.

6. 2- Prediction
If we collect particulate samples in “covered” and “uncovered” areas, then _____________________ ________because ____________________. Where will we find the most particulates? Why?

7. 4- Procedure Day 2 Procedure-
Use the magnifying glass to inspect each card.
Describe and draw the types of particles from each card in Data Table 1
Use a pencil to draw a vertical line and a horizontal line through the center of each sticker.
Label each square with a number. Count the number of particles in each square.
Record this data in Data Table 2.

Card 1- Uncovered
Card 2- Covered

10. Entry 5- Conclusion (graph)
No graph is needed for this lab…
Qualitative data is not graphed
Quantitative data will show patterns from data table due to the fact that there is not a tremendous amount of data.

11. Entry 5- Conclusion (paragraph)
Answer the following questions in your Conclusion paragraphs:
What are the similarities and differences in the types of particles found on your cards? (Qualitative data)
Compare the number of particles found on your cards. (Quantitative data)

12. Entry 6- Claims and Evidence
Make your claim- Answer your focus question.
State your evidence- What data do you have that tells you this is the answer?

13. Entry 7- Reflection
In your paragraphs(s) answer the following questions:
Does you data support your hypothesis?
What can you infer about where the particles came from and how they reached the location? What evidence do you have to support these inferences?
What possible limitations or sources of error might have affected your results?
What did you learn about particulate air pollution as a result of this lab?

14. Entry 8- New Questions
Write 2 new focus questions for a lab that could be done in the future based on the information you gathered in this lab.
