This is a lab I created for my high school Marine Biology class. Students study properties of water and how marine organisms have to adapt to living in water. In this lab students focus on finding measurable results of how salt water will affect living cells.
This is a class cooperative lab. Students are put into lab groups and have assigned tasks. However, all lab groups much work together as a class to come up with a common plan on how to tackle the inquiry and to share all the possible salinity tests.
This is an advanced stage inquiry. There are guidelines to follow in the student instructions, but students will have to work with their group and then with the class to come to an agreed upon procedure for all groups to follow, come up with formulas to use for data analysis that are consistent, and be in charge of assessing each other's results for accuracy.
Students collect data for a week, and use microscopes to sketch observations, as well as scales to get weights. Data is collected in student notebooks and as a class. Students can create their own lab reports based on data from the lab.
You will receive a 6 page Word document file, so you may edit as necessary for your own class. There are brainstorming questions, job titles and instructions for each group member, guidelines and rules to follow in the lab, basic lab procedures, and a data table to use to set up class trials.
