KS4 GCSE Physics AQA P12 Wave Properties Topic - 7 PPTs, 12 WS and 9 MS Bundle

When landed with teaching through lockdown, with our own internal resources that are really only suitable for delivering face-to-face with physical resources for demo and practical, this bundle fitted the bill to be a complete learning experience that I could pick up off the shelf and deliver online with my own personal take without having to reinvent the wheel, knowing that all the learning outcomes were being covered. The animations work and demonstrate the principles simply and well, and help make up for not having your usual physical resources to hand. For delivery in real classes, these do need you to add your own personal/school practical and demonstration angles to them, but that's all part of building a great scheme of learning, isn't it? It would be good if the worksheets were available as .docx so I could easily edit in/out the bits I want without having to go through a conversion step for each worksheet. And there's the odd typo (hey, we're scientists not English teachers!) <br /> <br /> This wasn't the first ThePhysicsStore resource I've purchased and it won't be the last, either (P15 bundle coming soon!) Thanks for some trustworthy resources!

I have recently purchased the Waves Properties Topic Bundle from your TES store and I am very please with the quality of the bundle, both in terms of the animation and as a KS4 lesson presentation. <br /> <br /> However, I was wondering the what are meaning of the acronyms on the bottom right corner of the slides, e.g. SK, RET, ADD etc.?
