Learning Targets and Goals
- 1. Can you explain and effectively communicate scientific and/or technical information, e.g. about a proposed object or tool, that is a solution to a problem in writing and/or through oral presentations?
- How will synthetic materials- like plastic polymers- impact society and the environment in positive and negative ways?
- 2. Do you recognize that pH is one way scientists measure ocean acidification, and that a very small shift in the pH scale represents a much larger shift in the chemical balance?
- What are the opposing sides of the pH scale—> measures acids and bases?
- Can you explain the impact of acidified (carbonated) water on different kinds of shells (mussels and oysters)
Today in Class:
First: You re-read the Ocean Acidification Experiment: the PLAN (Materials and Method) of this shell experiment – one more time.
Second: Then students moved into groups to run the Procedure for the Ocean Acidification Investigation.
- a. I had already mixed up a simulated ocean water (3.5% saltwater solution).
- b. Teams 1 and 4: measured 100mL ocean water in the beaker A
- c. Teams 2 and 5: measured 75mL of ocean water and 25mL of vinegar in beaker B
- d. Teams 3 and 6: measured 50mL ocean water and 50mL of vinegar in Beaker C.
- e. All groups completed the mixing of liquids (if you had 2 different liquids ) into a plastic cup.
- f. All teams measured the mass of the seashells before placing into the cup of liquids for their team.
- g. All teams measured the pH of the starting liquid.
- h. All teams recorded their data (and all teams’ data) on the data table.
Third: Sustainability Notes: (on Unit Notes page on this Blog).
a. Reduction in ocean species due to ocean pollution
b.. Changes in ocean temperature
c. Atmosphere changes due to human impact
Homework:
No Homework, but for those students who will be absent Wednesday due to band/ choir trip to Chicago- I did tell you what you would miss, and suggested you take the notes tonight (on the Unit Notes page).
