- Review topics for unit 2 on Dynamics of Chemical reactions and Ocean Acidification from the course outline
- Review the topic of ocean acidification from the NOAA website: https://oceanservice.noaa.gov/facts/acidification.html
- Relate the topics on this webpage with the topics listed on the course outline. How do they relate? Post your ideas in the “post” section of Edmodo
- There will be no lessons provided during our scheduled Spring Break (April 4-12)
- Answer to yesterday’s warm-up:amount remaining = 1/8 = (1/2)^3; 3 half-lives; time needed for decay = (4.46 × 10^9 years)(3) = 1.34 × 10^10 years
- Half life lab; lab due Monday; see Edmodo (lessons folder) for further instructions
- Post lab quiz Monday: what did you learn? Definitions; how do nuclides differ from one another?
- Warm-up: calculate a half life: U-238 decays by alpha emissions with a half life of 4.46 x 109 years. How long will it take for 7/8 of it to decay? Answer tomorrow

- Nuclear chemistry quiz on Wednesday (in Edmodo): know the three types of particles, the properties of the particles, how we can protect ourselves from the damage (sections 21.2 and 21.3)
During this trying time coping with our lives being affected by the COVID-19 outbreak and the school closure, I want to reassure you that I will still be providing high quality lessons that West Campus students have grown accustomed to. I will be posting the lesson agendas and objectives daily on my website (wcscience.com) for students and parents to have access to. I will also be using our Edmodo platform for other lesson elements. Students will be able to upload their work to that platform, where I will provide constructive feedback on how they may improve their work. The situation being dynamic I will be waiving late penalties as long as the delays are reasonable. Students may complete work on lined paper if they are unable to print the hardcopy of the material and upload photos using their smartphones or computers. Further instructions will follow in the days ahead.
Please stay safe and healthy during our extended absence from school. Please log onto Edmodo daily to keep up with your work. If you need to contact me you may e-mail me at email@example.com. I will be active during weekdays between 8 am to 3 pm.
West Campus High School
