Infectious Disease: Rapid Evolution

— National Academy of Sciences

8-11 0 favorites 0 promising practices https://koshland-science-museum.org/sites/all/exhibits/exhib_infectious/rapid_evolution_01.jsp Last updated: Fri, 08/27/2021 - 11:49 share

How It Works

This webpage on the evolution of disease provides clear information about how natural selection works with infectious agents. It also addresses the concept of exponential growth. After reading the information, click on the flash clip at the bottom of the first page to view a simulation of how a single E.coli bacteria reproduce. Keep in mind that Flash isn’t supported on all devices. You can also find information on HIV, Malaria, TB, and more. This is a great image for having students understand bacterial reproduction.

In the Classroom

Use this to teach evolution, bacteria, or population growth in biology and environmental science. This will help students better understand how bacteria reproduce, and why disease causing organisms are so very successful. Start a lesson on bacteria infections by asking students "why is bacteria such a big problem?" Ask students whether they think bacteria as a species are successful or not. Have students read and watch the flash simulation. Have students discuss the rate of growth, and make sure to point out that the simulation is timed just the way that bacteria reproduce in nature. This would also make a good lead into a conversation about how not all evolution is good for the human species. It will help to point out that humans are just another animal species, and need to be studied as such.

Coin Toss

— Shodor

3-8 0 favorites 0 promising practices http://www.shodor.org/interactivate/activities/Coin/ Last updated: Fri, 08/27/2021 - 11:49 share

How It Works

This activity provides the opportunity to explore experimental probabilities through simulation of a coin toss. In this activity you can view the results as a list, ratios and probabilities, and a table. In addition, the choice is available to view cumulative stats or not. The learners section of the site contains an explanation about probability and how it is used in science and medicine. The instructor portion has information on how the activity can be used in the classroom, links to standards, and similar resources.

In the Classroom

Use this site as an anticipatory set or "activator" to introduce a unit or lesson on the difference between chance and probability. Share the site on a projector or interactive whiteboard. Complete the activity showing results as a table. Then have students convert those results to a table and ratios. Allow students to explore the site and compare results - discuss comparisons between individual results and results found when combining all results.

Area Explorer

— Shodor

2-8 0 favorites 0 promising practices http://www.shodor.org/interactivate/activities/AreaExplorer/ Last updated: Fri, 08/27/2021 - 11:49 share

How It Works

This site provides multi-leveled practice with calculating the area of random shapes. The applet allows the creation of random shapes to be used in finding area. Options allow for changing the perimeter, displaying the rectangular outline, scored or not scored, and the amount of units to be included. The learner area of the site explains the concept of area and includes charts comparing metric to standard units as well as an explanation on how to convert square feet into square meters. The instructor area includes links to standards and some textbooks, information needed for classroom use, links to similar resources, and a link to downloadable exploration questions.

In the Classroom

Use this site as an anticipatory set or "activator" to introduce a unit or lesson on area on a projector or interactive whiteboard. Then have students complete the exploration questions on their own or with a partner. Use this site on a projector or interactive whiteboard to discuss and informally assess prior knowledge as you start your study of area. Make a link on classroom computers to use as a center activity.

How It Works

Find excellent videos about a variety of physics and astronomy topics with this great site. Choose a symbol and view the video that explains and depicts the meaning of the symbol. View a variety from total solar eclipse to pressure and vacuums to magnetic susceptibility. Videos are hosted on You Tube. Schools that have this resource blocked will need to ask for it to be unblocked to use in class. Click on planets to view great videos of each of those in our solar system. View information on scientists and the sixty symbols project by clicking on the tabs across the top.rn<br><br>rnCaution: Be sure to preview the videos before sharing them with your students. Our editors found one that included alcohol in the experiment, all others appeared appropriate.

In the Classroom

Use on a whiteboard or projector for the entire class to see if You Tube is blocked for student but not for teachers. Assign the viewing of a specific video as a homework assignment. Have students take notes on the topic for further discussion in class or to apply the information to laboratory activities or demonstrations in class. Encourage students to follow these clever videos to develop their own videos for teaching concepts to other students in and out of their school. Challenge students to create a video and share using a site such as SchoolTube (<a href="/single.cfm?id=9437">reviewed here</a>).
