Model & Explanation checklists as a scaffold to guide students. Checklist also serves as a formative assessment.
Model revision as a way for students to demonstrate growth and make their thinking visible.
The anchoring phenomenon of this unit asks students to watch a series of videos and develop a notice/wonder chart. Students learn that oysters and other shellfish seem to be "dissolving", but aren't sure why. Students will go through a series of lessons with incorporated labs and develop a final model to explain the chemistry behind what is happening to ocean shellfish.
Students undergo a series of investigations. These include investigating proerties of acids and bases, proving carbon dioxide is actually entering our oceans using the BTB indicator, and creating Calcium Carbonate (shells) using Calcium Chloride & Sodium Carbonate.
Student initial models during the first day of the unit. Students were asked to simply model why they think oysters were dissolving. Created on whiteboards so students can easily edit and not feel tied to their initial ideas.
Accompanying Presentation
Data from NOAA showcasing CO2 emissions by year, which students analyzed and graphed
Students analyze maps of Southern California to find patterns in pollution levels.
To wrap up the lesson segment, students were tasked with researching, designing, and constructing a house that runs on renewable energy. The house had to use a solar panel and wind turbine to power 2 LEDs. Students learned about alternate energy sources and the possibility of divesting from fossil fuels that harm their city.
Photosynthesis presentation with integrated pear deck questions meant to check student understanding. Presentation introduces phenomenon and includes a variety of visuals to offer multiple modalites for students to interact.
Presentation of the lab portion of the lesson segment. Inquiry is fostred when students discover the global population is increasing while food supplies are decreasing. Students provide ways we can solve food shortage issues, and will use their lab data to evaluate solutions.
Rainbow tube lab to practice lab techniques & lab safety during the first week of school.
Iodine Clock reaction used during fuels unit (why do cars run on gasoline and not rocket fuel?) to model chemical reactions.
Students created electric cars to try to limit emissions coming from internal combustion vehicles. Students learned collaboration/teamwork skills, and designed their own vehicle to compete against other groups.
