Unit C7 · lesson 4 of 4
Every reaction moves energy. Some push it out into the room and some pull it in, and a thermometer in the beaker is how you tell which. This unit is about which way the energy goes, why nothing is ever created or destroyed doing it, and how much a leaking beaker costs you when you try to measure it.
Unit C9 · lessons 1 to 2 of 4
Some metals sit in the ground as the metal itself and some have to be torn out of a rock with electricity, and the difference is one order that was worked out by putting metals into liquids and watching. This unit is about that order, what it predicts, what it costs — and then about the materials that are not metals at all.
- 04Measuring a temperature changeInvestigationFour groups run the same reaction and get four different answers. One of them is closest to right — and it is not the one with the neatest handwriting.Open this lesson
- 01The reactivity seriesClassifyPotassium attacks cold water hard enough to set fire to its own hydrogen. Copper carries cold water through houses for fifty years and does not change. Both are metals — so what is the difference made of?Open this lesson
- 02Predicting displacementModelAn iron nail goes into blue copper sulfate and comes out coated in copper. Nobody added any copper. So where did it come from — and could you have said so in advance?Open this lesson
