Topic 1 Test - Introduction to Paper 2 Part BHi Mariya, You might want to check the old "check your understanding" that I developed for the 2015 course https://thinkib.net/ess/page/43959/23-checking-your-understanding-questions Also...
Topic 2 Ecology ActivitiesYes, I have been worrying about the method too but I really wanted the second opinion before asking the student to restart with a new RQ - I think the mine is still operation but they may have added mitigation methods - however, given your advice,...
Writing the Independent InvestigationHeavy metals settle so maybe research if they are likely to be detectable in water samples, years later. I suspect they are in the sediment unless actively removed. If this is the case then the method isn't supportable and it's a bit of a problem.
Writing the Independent InvestigationHi Zoe, Zinc, lead, cadmium and arsenic - using a litmus paper style testing kit for heavy metals. I doubt it was the same method as the environmental agency but the idea was not to do a comparison - it was more to see if there was a difference...
Writing the Independent InvestigationHi Lisa, How was the water tested? What metals were being tested for? Was the same method used as the environmental agency? The metals may have settled into the sediment. It's very difficult to test for heavy metals at a school level.
Writing the Independent InvestigationHi Zoe, One of my students has collected data upstream and downstream of an open cast mine - testing for the presence of heavy metals - the river has had a history of heavy metal pollution but the results show no marked differences. The student...
Writing the Independent InvestigationHi Alison, I wrote over 20 questions last night so you should see them over the weekend or even today.
Quiz - HL Ethics LensYes that's my plan - I have 5 of my own students signed up for an ESS essay already. I don't think there are big differences in how the students proceed, just in the assessment. I'm trying to find the time for this but it's tricky.
