- Cassie Javner was just tagged in a comment: Hi @Reshmi Joseph and @Cassie Javner! I would love to hear how the integration of real-world cases in chemistry classes has affected students. Moving forward, do you plan to apply this kind of practice across the entire syllabus?I am not used to seeing real-world cases in my undergraduate and even in high school lectures (in the Philippines set-up). However, when I experienced this approach in my graduate programs, it had a much deeper and more personal impact. It made me reflect on my daily choices and how they might lead to broader consequences.With the conventional chemistry syllabus as it is now, I strongly agree with Reshmi that integrating additional real-world case discussions would require extra time and could affect the goal of covering the entire syllabus within a semester or academic year.Given this challenge, how do you navigate or work around these constraints?...
- Cassie Javner was just tagged in a comment: I don't have any concrete resources for this, but my hope this school year is to really focus on integrating real-life situations and issues into our curriculum to spark students' interests in green chemistry. I want to integrate more environmental science topics with our traditional content so that students see the connections between the large scale issues that are being talked about around them and the building blocks that drive those issues. I want to talk about water quality, air pollution, and I think I want to add global warming with an energy/heat unit that has been missing from the curriculum at my school for far too long. I think if I can focus on these 3 tie-ins this year, I can build out more, particularly integrating industry, next year. @Cassie Javner ...
- Cassie Javner was just tagged in a comment: I do! I essentially do elephant toothpaste, but do it inside a jack-o-lantern. One of my professors in college used to do it for Halloween. I've always called it the "vomiting pumpkin" demo, but with the students, I like to jazz it up by claiming that this happens on the day you have chemistry closest to Halloween due to a curse that occurred when a student who many years ago said that they didn't need to wear safety googles. (It's a cheesy twist, but the students do seem to find it funny.) It's one of my few demos throughout the year. Now I'm rethinking my other demo that I've done for my Halloween advanced chemistry class though, as it doesn't align with green chemistry principles. (A small amount of lycopodium aerosolized over a tea candle inside a jack-o-lantern to make it look like a fire-breathing pumpkin.) I've also traditionally linked that demo back to both safety and thermochemistry, and it's also one of 3 demos I do throughout the year---most of the experiments in both of my classes are hands on experiments. Any ideas here would be appreciated!@Cassie Javner ...
- Cassie Javner was just tagged in a comment: Thank you for sharing these resources! I have used the chemical reactions lab from beyond benign with my high school classes, and I think that the prelab is a great addition. It seems like an activity that would help students build agency in evaluating the risks involved in the use of different chemicals/processes. I also really appreciate the case study vignettes in the presentations/resources that you shared - those types of real stories really help students engage with the chemistry and gain a deeper vision for its relevance. @Cassie Javner ...
- Cassie Javner was just tagged in a comment: At my school the AP Chemistry students do a demos show with the help of their AP teacher! It's great, they do the electric pickle, a couple of color changing ones, calcium carbide pumpkin. There are a couple more that are slipping my mind. I for sure would love to hear some more that anyone does that is more sustainable/eco-friendly. I know a few use some pretty harsh chemicals. @Cassie Javner ...
- Cassie Javner was just tagged in a comment: Thank you for sharing these! I haven’t used either of those specific resources yet, but now I definitely want to check them out. I’ve been thinking to try and bring the principles of green chemistry into the class through project-based learning, like a unit where students investigate conflict minerals and find alternatives based on periodic trends. It’s been a great way to connect real-world issues to our content. We do the "Conflict and Cans" PBL where is what so far I have thought to integrate this into.I’m always looking for ways to integrate green chemistry more intentionally, especially with limited time in class. These look like they’d be great for that. Have you used either in a high school setting?@Cassie Javner ...
