I can process results (requirements 9-11).
Mahi Ako/Learning Tasks
Part 1
If you were absent, watch the section on "SAV" Ratio Demo in the lesson recording and the two videos about surface area to volume ratio to understand the theory.
In pairs set up your surface area to volume ratio experiment. You can work together to complete up to slide 10 on the "Surface Area to Volume Ratio Practical Google Slides" and enter your data on the "Surface Area to Volume Ratio Google Sheet".
Note, if you were absent for this lesson, please work on the Mahi Choice instead of task #2.
Part 2
If you were absent, watch the section on "Planning Section Clarifications" and "Calculating SA to Volume Ratio" in the lesson recording.
Working in pairs, complete the planning section write up for the "Surface Area to Volume Ratio Practical Google Slides."
Part 3
1. If you were absent, watch the section on "Internal Info" in the lesson recording.
2. Working in pairs, finish the planning section write up for the "Surface Area to Volume Ratio Practical" Google Slides.
3. Working individually, start on the results analysis by entering and processing your data in the "Surface Area to Volume Ratio" Google Sheet and work on remainder of the Google Slides. One person in your pair should enter your groups data into the "Surface are to volume ratio class data" Google Sheet.
4. If you were absent, watch the section on "Discussion Info" in the lesson recording.

Mahi Choice
Start at the level you feel comfortable with and then keep levelling up!
If you’re looking for “homework” or evidence in case we need a UEG, these are perfect tasks to do.
Remember, you’re not expected to do all these tasks. These are just recommendations to give you ideas on how to support your learning.
