Scanning Electron Microscopes Teacher Resources
Find Scanning Electron Microscopes educational ideas and activities
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.
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.
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.
What does a human hair look like at 40 times its normal size? Young scientists find out the answer to that question and more in an introductory microscope activity. In the description, it says the investigation is intended for ninth grade honors biology, but it seems more appropriate for middle level life science, or wherever learners are introduced to microscope use in your district.
When sugar is dissolved in water, is it gone forever? Can it become sugar again? In a lesson plan focusing on both observation and crystal structures, middle schoolers attempt to grow sugar crystals on strings dipped in sugar water. Note: The lesson plan refers to a data table, which is only found in the lesson plan in the Additional Materials section below.
When your AP biology class is studying DNA and genomes, this worksheet 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.
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.
Students explore the world of the very small using a Flash plug-in Virtual Electron Microscope. They complete and discuss an activity in which unknown samples are placed under the computer simulated microscope to determine where the cells came from. Hints for cell types and a self checking system make this seem like a game.
Students research living organisms by exploring their school grounds. In this microscopic observation lesson plan, students gather materials, insects, and objects from their playground and schoolyard and bring them into class. Students utilize microscopes and magnifying glasses to investigate what really lives in their yard and school.
Students investigate nanostructures by experimenting with sugar. In this crystal formation lesson, students utilize different sugar samples to grow sugar crystals in a group experiment. Students complete worksheets including an evaluation of their crystal growing experiment.
Students experiment to determine a way to waterproof a piece of cotton fabric. In this scientific inquiry lesson, students use reference worksheets to explore waterproofing and the use of nanotechnology in engineering everyday objects.. They conduct an experiment to waterproof fabric.
