Forming a Precipitate
Can you mix two liquids to make a solid that is insoluble? Yes, you can, and pupils see this as the lesson uses more than one combination of liquids to form a solid. Through two teacher demonstrations and a hands-on activity, scholars...
Curated OER
Gases, Liquids And Solids
Students investigate how gases are different from solids and liquids and that they can evaporate and condense. They observe water boiling in a teapot and discuss what happens when the steam touches a cold window, complete an online Heat...
