With your group:
Materials: list any materials you and your partner decide to use in your lab notebook
Procedure: write a step-by step procedure of how you will measure change in the algae population over 3 days. What baseline data should you collect today?

Check your plan with me and get started for day 1 data collection!

4. Goals for Today: Get your algae and do your day 2 counts.
EVERYONE should count ONE slide. Share the fun!
Use more than one scope if you want to.
Open books to p and review food chains and food webs.
Read “Oh what a tangled web” and get three colored pencils or markers: green, blue, red and orange

5. Algae Lab Write-up
Get your algae and do a day 4 count if needed. WASH ALL GLASSWARE AND RETURN IT TO THE BINS UP FRONT!
Make a LINE GRAPH of your data in your lab notebook under your data table. Don’t forget your TAILS!
Write an ANALYSIS AND CONCLUSION of the data. Answer all the questions on your lab sheet. Which tubes had the most algae growth? Which had the least? What was the difference between each tube each day?
Write a SUMMARY OF FINDINGS. Which nutrient caused your algae to grow the most? Did any of the nutrients seem to harm the algae? Connect your findings to the “big picture.” What would this mean to animals in the Narragansett Bay? In Montana?
