Ms. Peters explained that to learn more about the air monitoring program you can scan the QR code or visit cnsc.info.ccsn@cnsc-ccsn.gc.ca
The testing team sets up air monitoring equipment. Good testing sites are near large open areas. In this case the testing team set up near a local high school.
The testing equipment samples air for iodine-131 and cesium-137. The numbers after the element name indicate the mass numbers for that particular elements isotope.
A special glass filter, in front of the air monitoring canister helps to capture the air and directs the air flow into the second sensor – a carbon filled canister.L

One famous study explored how students felt about their revision by comparing those who did lots of re-reading with those who did self-quizzing (technically known as retrieval practice). The study found that, given the choice, students much preferred to re-read. This is presumably because it is safe, comfortable and doesn’t force them to confront what they do or don’t know. As such, they leave their revision with a false sense of confidence and with their short-term self-esteem intact. However, when looking at the students’ exam results, the study found that students who did the retrieval practice tended to perform better.
The extent to which students prefer this less effective studying method is actually quite dramatic. Another study found that 84% of students use re-reading as a revision strategy, with 55% of them stating it was their favourite strategy to use.
Teachers can help students here by doing two things. The first is to explicitly teach them the benefits of retrieval practice. Second is to help them understand exactly what retrieval practice looks like. This could include flashcards, mind maps, multiple choice quizzes or even verbal questions and answers. If students know how to use these study techniques and recognise why they work, they are more likely to use them.

Although research isn’t conclusive, there’s evidence to suggest that excessive screen time has a negative effect on the mental well-being of teens. One study found that teens who spent more than an hour on screens were less curious, more easily distracted and had a difficult time making friends. Those who spent an excessive amount of time on screens were twice as likely to have anxiety or depression. Researchers even found that excessive screen time seemed to negatively affect teens more than it did for children. But again, the research can’t state for sure whether more screen time definitely leads to depression and anxiety.
