In this microscope worksheet, students use an on line site to answer questions about how a Scanning Electron Microscope works. They also conduct a virtual microscope activity where they view ten specimens and identify what each is.
New Review Powers of Ten with the Blue Morpho Butterfly
Explore the powers of ten while examining a Blue Morpho butterfly wing. Learners discover there is a lot more than meets the eye when one looks close enough.
Learners observe different substances under the microscope. In this space science lesson, students identify the different features of SEM images. They formulate a conclusion about the images of Mars meteorites.
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.
The differences between prokaryotic and eukaryotic cells are explained and the parts of each are highlighted. Discover the major organelles found in an animal cell and each of their functions. Paul Andersen does an excellent job once again with his Smart Board presentation.
This lesson will make an impact, especially on scientist-athletes who may have an interest in waterproof clothing! Acting as materials engineers, they work collaboratively on waterproofing pieces of cotton fabric. This challenge is preceded by reading about nanotechnology and the hydrophobic effect. Expect an enduring effect on emerging engineers!
To prepare for the activity, STEM classes read about nanotechnology and the amazing properties of graphene. They collect a graphene sample from pencils, and then connect them into simple circuits to determine whether it makes a better conductor or insulator. Note that although Next Generation standards are listed for primary grades, this activity is best suited for upper-elementary science classes.
Blow your learners' minds with a sweet lesson on nanotechnology that uses sugar to demonstrate the difference nanoscale surface area makes in dissolving and crystal formation. Plenty of supportive background information is read to introduce the concepts, and then two activities are carried out. Since the sugar crystals take about a week to form, you will need to set aside a later class period in order to wrap this lesson up. Though the publisher mentions many grade levels, this would be the best fit for middle schoolers.
Nano-nano! Nanotechnology can seem like it's from another planet! After learning about this tiny technology, collaborative groups experiment with how smaller particles affect chemical reactions. They do this by immersing a whole and a crushed antacid tablet into equal amounts of water. Nanotechnology is a fascinating topic for your STEM curriculum.
Fascinating reading about nanotechnology, nanoscale properties, and liquid crystals precedes a fun activity for young engineers. They measure their hands in nanometers, research, and then investigate how heat effects a sheet containing liquid crystals. These sheets are similar to the material in mood rings, so consider having a few on hand to demonstrate!
A reading precedes the activity in order to familiarize learners with just how small a nanometer is. Then, small groups measure classroom objects and convert units into nanometers. The publisher doesn't mention it, but the reading material provided can easily be used when addressing Common Core State Standards for reading informational text or scientific literacy. Math and science are also involved in this comprehensive resource.
Stop the raindrops from getting into the house! Eager engineers learn about roofing history and waterproofing by nanotechnology. They get into groups and work on designing a waterproof roof for a small model house. The accompanying handout provides space for planning and critical analysis questions for follow-up. Miniature rain storms are sure to make a splash with your science or engineering class!
New Review Scale Models
With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.
Extensive reading is done in order to learn about scanning probe microscopy and nanoscale. Afterward, individuals use a pencil to probe an unidentified object that is inside of a box so that they cannot see it. Using only what they could gather via the probe, they draw the object.
Following directions from a colorful slide preparation card, beginning biologists examine three different live microorganisms: bacteria, yeast, and paramecia. This is not an unusual activity to do with your class, but if you are doing it for the first time or need a refresher, the lesson plan is so well-written that you will have no questions. Just make sure to order your live specimens early enough to have them on time.
New Review Is Measuring an Art or a Science?
Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools.
When sugar is dissolved in water, is it gone forever? Can it become sugar again? In a lesson focusing on both observation and crystal structures, middle schoolers attempt to grow sugar crystals on strings dipped in sugar water. Note: The lesson refers to a data table, which is only found in the lesson plan in the Additional Materials section below.
Scribes once had to copy books by hand, and it was this process that birthed the word miniature. Watch as minium, or red lead used for pigment in ink, becomes miniature. The resource, part of a series of videos on vernacular, includes questions, additional information, and an online discussion question.
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.
