Students use the free computer game Pingus to learn how engineers, specifically environmental engineers, use their technical writing skills to give instructions and follow the instructions of others. Students learn to write instructions to express their ideas in clear, organized ways using descriptive, un-ambiguous sentences, as an example of one type of technical writing that important for engineers. The students write instructions enumerating how to beat a game level, which represents surveying that level for environmental problems. As a test of their instructions, students review each others' instructions and offer suggestions for improvement, and then revise their instructions to make them better. Students also see some examples of environmental problems.

Radiation is natural and all around us. It can be man-made too. But it's nothing new. It is, quite simply, part of our lives. RadTown USA is a virtual community showing a wide variety of radiation sources and uses as you may encounter them in everyday life. Explore this interactive, virtual community of houses, schools, laser light shows, construction equipment, flying planes, and moving trains. Each place in RadTown helps you learn about radiation sources or radiation- treated items you might find there.

In this lesson students create a model beaver dam and demonstrate changes in the ecosystem community pre- and post-dam. Students hypothesize about changes that they would expect to see to the ecosystem after the beaver dam is built.
NGSS: 5-ESS2-1, 3-5-ETS1-3
Time: one or two 50-minute class periods
Materials: ecosystem cards (included), seed trays or long Tupperware containers, wood/popsicle sticks, sand, rocks, and clay

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:
"The interactions between viruses and prokaryotes play a key role in shaping microbiomes. However, little is known about the factors influencing host-virus interaction networks, especially when it comes to host factors. To close this gap, researchers constructed a host-provirus network out of over 7,000 species-level prokaryote genomes from many environments. Proviruses are virus genomes that have been integrated into the host genome, allowing researchers to detect them from available genomic datasets. Using this host-provirus network, the researchers then calculated the host interaction specialization, which quantifies how specialized a given host is in relation to the available interacting virus partners. Broadly, fast growing prokaryotes showed less virus specificity than slow growers. This negative growth rate-specialization relationship was widespread across the Earth’s microbiomes..."
The rest of the transcript, along with a link to the research itself, is available on the resource itself.

This offline OLogy game is a fun way to illustrate how all the organisms in an ecosystem are connected and depend on one another to survive. To play this game, you'll need at least six students and index cards, a marker/pen, and a ball of twine. A list of organisms to connect is included. As students toss the ball of twine to each other, they make connections between the organisms they are linking. The game ends with a discussion about what would happen to the "web of life" that's been created if an organism left the ecosystem.
What's the Matter with Trash?Have you ever wondered what happens to trash …
What's the Matter with Trash?Have you ever wondered what happens to trash once you throw it away? You may know that it goes to a dumpster or that the trash collectors come and get it. But, what happens then? Some of the items you throw away will break down into smaller parts, some might get heated in fire, and others will get buried underground in landfills and might never break down at all! Trash and the many ways humans “get rid” of it can cause a number of health issues for the community. You will explore the properties of materials we throw away and how you can make your community cleaner and healthier by learning to recycle, reuse, and reduce waste. You will then influence your community by convincing others to improve solid waste management.
