Ocean Chemicals Slides Presentations:
Directions: You and your team will design the procedure of a controlled experiment that tests your assigned ocean chemical on mustard seeds. You will use the foundation of the caffeine seed lab in the scientific method project to help you with your design. The goal is to develop a step-by-step user friendly procedure that most people could follow and implement without confusion and error. Your procedure should be descriptive like a cookie recipe :)!!! You will need the components below in your report:
Listed below are your team's assigned pollutant:
Team 1: Oil (from oil spills/leaks)
Team 2: Sunscreen (from beach use)
Team 3: Excess Salt (from desalinization)
Team 4: Fertilizer runoff (from farming)
Team 5: Oil (from oil spills/leaks)
Team 6: Sunscreen (from beach use)
Team 7: Excess Salt (from desalinization)
Team 8: Fertilizer runoff (from farming)
Team 9: Excess CO2 in ocean causing ocean to be more acidic (from global warming) Hint: In this case, test an acid to mimic CO2

The goal is to develop a step-by-step user friendly procedure that most people could follow and implement without confusion and error. Your procedure should be descriptive like a cookie recipe :)!!! You will need the components below in your report:
- Just like the caffeine lab, you should vary the concentrations of your pollutant and include a control! You will need to describe how to make the varying concentrations of your pollutant. How much volume or weight will you use of the pollutant? What and how much are you going to dilute your pollutant with?
- Describe why the experiment is considered controlled.
- You will also need to be VERY specific about the quantities of the materials and equipment needed and list any safety hazards (come up with at least 2) that may be encountered during the lab. Hint: Are you dealing with any dangerous equipment (e.g. hot plates) or toxic chemicals?
- Construct data tables that will be filled in during the lab and identify the quantitative and qualitative data that will be collected.
- Design the graph (types of graph and titles) you will use to display the data once collected.
- Your team must also identify the independent variable, dependent variable, test subjects species, control group, and test group and explain how/why your experiment is a "controlled" experiment (Hint: Identify that your experiment has a control group and list the variables that are the same and different between the control and test group).
- Before you begin your design, research how your chemical pollutant is affecting plants and/or animals in the ocean. Also explain how human activity is causing your pollutant to end up in the ocean. Be descriptive!
