This is a 40 slide powerpoint reviewing a unit about protists (Amoebas,Paramecium, Volvox and Euglena) - how they move, where they live, their organelles, where they get their energy, etc. it also includes questions about plant cells and animal cells and their organelles, prokaryotes versus eukaryotes and autotraphs versus heterotrophs. (7th-grade science essential standards). It is best used with the "Protists Cells Review Guide" and the "Protists Cells Unit Test" I use the powerpoint for student whiteboard races, which students find exciting and engaging. Each powerpoint slide posts a question or vocabulary word definition - and students race write the correct word or answer their whiteboards. It could be used for different review games depending on the class and resources.
