Find teacher approved Scanning Electron Microscopes educational resource ideas and activities
Students match Scanning Electron Microscope (SEM) pictures with real life objects. They discuss the uses of the SEM. Students identify the real-life origins of samples by matching some SEM pictures with real-life objects. Students analyze the samples and choose the real life objects they resemble. Students develop an appreciation for the applications of the SEM.
Students study the discovery of the electron and how it led to other inventions and discoveries concerning electrical current. They observe several demonstrations concerning electricity. In one activity, they determine whether or not a galvanometer is a reliable lie detector test.
Wow! Separate organelles from the cells of dried peas. Observe vacuoles in beet cells. Watch protists in action. Examine SEM photographs. Beginning biologists get a complete exposure to the structure and function of cell organelles. Two assessments are also available, which you can assign as homework. These activities can serve as the foundation for your curriculum on cell structure.
It has appeal; Vivid microscopic images or colorful diagrams are displayed on almost every slide of this introduction to cells. Visit scientists who contributed to cell theory, learn the general components of cells, and compare prokaryotes to eukaryotes. As enrichment, explore the endosymbiosis theory. Overall, this would be an informative introduction to cells for your high school biology inquisitors.
Youngsters examine four fossil replicas and chart their time periods, vertebrate or invertebrate, and the names of other organisms living at the same time. A specific fossil kit is available for sale if you do not have the same samples. The background reading material and student handouts are high-quality, so it may be worthwhile to invest in the fossils required: ammonite, oviraptor egg, crinoid, and trilobite.
When your AP biology class is studying DNA and genomes, this learning exercise will provide a detailed review. On the first page are diagrams and matching SEM (scanning electron microscope) images of different levels of DNA packing to be outlined. The remainder of the assignment requires learners to write out answers to questions on multigene families, gene regulation and expression, cancer, and other mutations.
