Students will review the components of respiration and photosynthesis reactions to illustrate how the two are complementary. Then students will investigate what impact megafire smoke may have had on photosynthesis for California nut trees. Then students will apply their knowledge by predicting the outcome for photosynthesis and respiration in several scenarios.

Scientists have discovered that Dicyrtomina minuta, a species of globular springtail, can perform the fastest backflip of any animal on Earth. Use this discussion to have students review how the research team studied springtail backflips by analyzing high-speed footage.

Then, in this related activity by DataClassroom, have students analyze graphs of the springtail research data to learn about the linear velocity, angular velocity, linear acceleration and rotational acceleration of springtail flips using this Stacked Graphs and Biophysics with Spring-Loaded Arthropods activity.

Learn how scientists use vampire bats' unusual locomotion to investigate mysteries of their blood-based metabolism. Then, answer questions about this study’s experimental design and discuss how chemical analysis data can support conclusions and answer scientific questions.

Students will learn how their bodies help protect them from bacteria, viruses and other foreign invaders. Have students review the major components of the immune system and investigate the life cycles of a few prevalent pathogens of polar bears, focusing on the mode of transmission and effects of being infected by the pathogen. Students will then infer why polar bears are being exposed to these pathogens more regularly.

A carnivorous plant enzyme and an enzyme from a symbiotic fungal friend expedite digestion of ants. Use this as an example of enzymes, to introduce catalysts to your students. Then have students investigate how enzymes relate to catalysts, create their own catalyst metaphor and find another example of a catalyst or enzyme. Have students share examples and, as a class, discuss why scientists are interested in learning more about enzymes or other catalysts and potential applications of catalysts.

To survive, creatures need to be able to sense many aspects of their environment, including food options. Scientists have recently discovered that the northern sea robin, an oceanic fish, has legs used for walking and also for tasting, to find buried meals. Begin a unit on natural selection/evolution by reviewing what these terms mean. Then, provide example organisms to explore their different types of adaptations (structural, physiological and behavioral). Finally, have students create their own species with adaptations specific to unique human- or natural disaster-influenced habitats.

Biologists didn't design their experiments looking for glow-in-the-dark feet, but sometimes scientific failures yield surprising discoveries. If glowing toes sound batty to you, learn how scientists illuminate the secrets of a flighty mammal while answering questions about the scientific process.

A recent study found that a species of globular springtail can perform the fastest backflip of any animal on Earth. In this activity, students will research another Olympics-worthy arthropod competitor and describe how they’d measure performance in their imagined sports event.

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.

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.

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.
