Coral reefs are one of the most biodiverse ecosystems on the planet. Along with providing food and shelter for a variety of marine organisms, coral reefs reduce erosion and protect coastal cities from storms. However, coral reefs are threatened by the effects of climate change. In this activity, students will model the complex interactions that occur within corals, their ecosystem and the Earth’s spheres to learn about how climate change harms coral reefs. After modeling how these interactions change with increasing ocean temperatures, students will brainstorm potential ways to solve or mitigate coral bleaching.

Use shooting stars as an example phenomenon to explain how phenomena are studied using the Science and Engineering Practices and have students evaluate the claim, evidence and reasoning for why hydraulic engineering may have helped ancient Egyptians build the pyramids using these lesson plans tied to articles from the September 7 & 21 issue of […]

To investigate why some meteors create persistent trails, scientists filmed the New Mexico sky for two years, recording streaks of light. Use shooting stars as an example phenomenon to generate student interest, wonder and questions. Then, have students explore how this phenomenon was studied using Science and Engineering Practices, while evaluating the study’s design, limitations and possibilities for future research. Finally, have students search for another phenomenon that interests them and begin asking questions about it.

How did the ancient Egyptians build the pyramids? It's an age-old mystery. A new study points to hydraulic engineering. But does this idea really hold water? Some experts in the field argue against new evidence being provided to support such claims. Learn how researchers use evidence to support claims while discussing the value of healthy skepticism in science.

Use news articles from the August 24 Science News issue to discuss a new possible element and learn how elements get onto the periodic table and practice what happens during transcription and translation while learning about recently analyzed woolly mammoth DNA.

Scientists studied ancient woolly mammoth DNA that had been freeze-dried in place, preserving it and retaining its shape. The researchers adapted a technique for studying the structures of chromosomes within a nucleus to determine which genes were turned on and off in the mammoth genome. In this activity, students will review what happens when genes are turned on by completing exercises that illustrate hypothetical DNA base pairing and simplified examples of transcription and translation.

Scientists have been able to study genetic activity in an ancient woolly mammoth’s DNA, thanks to a new method. Learn about the research study and the preservation of the DNA while thinking through the implications of having certain genes turned on or off.

Take note — there could soon be a new element on the block. By smashing atoms together, scientists have been expanding our periodic table of elements beyond what occurs in nature. Learn how scientists create them while answering questions and discussing how such innovations may help us in the future.

Integrate recent articles from the May 4 & 18 issue of Science News to have students discuss how graphs can promote misinformation and learn about unconventional approaches to tattooing while answering experimental design questions.

Students will work in groups to answer questions about graphs and data visualizations. Then, they will discuss data literacy and how graphs can promote misinformation

When Ötzi, the mummified iceman, was discovered in 1991, researchers thought they knew how he got his ink. But new findings cast doubt on those assumptions. Learn about unconventional approaches to tattooing and answer experimental design questions, such as the importance of sample size to a scientific study and the difference between quantitative and qualitative evidence.

Use two articles from the April 20 issue of Science News to have students think critically about methods of training AI that can teach them how to influence human behavior and have students conduct observations of an animal and reflect on what they can learn about animal behavior.
