Hello Jesus, First, I don't think you want 10' spumes coming out of your cylinder!  It's probably a concentration and quantity thing at play to get those. We always stored our peroxide in the science lab fridge to keep it from decomposing and I've always done this demo with manganese dioxide powder.  Always seemed to work well.  It's fun to do the oxygen test by dropping a glowing wood spli...

Our school had the same issue - but not as far a distance as yours!  We ended up making portable kits for different experiments/activities and used an online Google sheets document that listed them.  We would write our names beside the kits we had in our classroom. Worked ok. Hope this helps, Gabe

Without knowing the specifics of Amplify Science I can’t say precisely what to do, but I checked out their website and have some general advice that might help. First, this is your summer break – take some time to unwind and don’t think about this at all!  About three weeks from the beginning of term, find your favourite place to read and start going through the frontend material.  Consider...

4 Excellent resource for STEM and engineering
I have been using this podcast for years in my design process and STEM workshops for teachers! It expertly and clearly goes through the engineering design process, explaining each step. I use this as an introduction and have even copied their use of symbols for each step to create handouts to students as they go through the steps (see my collections). If I could have put 4.5 stars I would have. My only hesitation in giving it a 5/5 is that the sound is muffled and the video quality is medium resolution - making it a bit tough to use in a group setting. All in all, a fantastic resource that I have come to rely on heavily in my pd workshops.

A compilation of handouts, rubrics, presentations on STEM and Engineering Design I have used and shared in workshops. Some YouTube video links to help. [Note: The focus is primarily on the engineering design process of STEM, but the activities are good integration]
