Physics 4-12-19 Wave Interactions

PHYSICS: Cool thing, standing waves! How’d you like making waves with slinkies? Are you okay with constructive and destructive interference?

Here’s the slinky activity for today. Stretch the slinky a pretty good length between you and your partner, but not enough to overstretch the slinky. Below that, the discussion of wave interactions.

Hon Chemistry 4-12-19 Single Replacement Reactions & the Activity Series

HON CHEMISTRY: Moving right along with the 17 types of chemical reactions, here are the single replacement reactions – and you also got a head start on the activity series!

This makes 15 reactions so far, and we’ll do the rest on Monday. Careful though, memorize, but don’t just memorize them. Make sure you can apply them as well. When you start to work any equation, first determine what type of reaction it is, then figure out what rule applies and follow it to determine the products. I believe in you! You can do it!!
