Arthropod Olympics
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 Conference
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.
Pairing up to create proteins
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.
Turning genes on and off
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.
How Ötzi Got His Ink
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.
Organism Observations
Students will observe animal behavior via live camera feed and reflect on their observations. Then they will learn about how animal behaviorists use camera traps and field observations to infer meaning from animal behaviors.
A peek inside
Students will learn about the openVertebrate project and how it is digitizing vertebrate anatomy using CT scans. Then they’ll explore the archive, form a scientific question about one of the specimens and consider how to research that question.
Data on dwindling migratory species
Students will analyze and compare two graphs to summarize a recent report about animals protected by an international treaty called the Convention on the Conservation of Migratory Species of Wild Animals before discussing the possible next steps and limitations of the treaty.
The Tiny “Toad” of Many Crowns
Scientists in Brazil have just discovered a creature that claims two small but fierce titles: the smallest known vertebrate and the smallest known amphibian. This raindrop-sized vertebrate earned a rather misleading name for itself — the “flea toad.” Use metric units to make and compare measurements and learn the differences between toads and frogs before discussing the misleading nature of the amphibian’s name.
How an ant shook up an ecosystem
How can one tiny ant species cause a savanna-wide shift in the food web? Outline the cascading effects of the disruption of one mutual relationship and create graphs that highlight how an invasive species can have significant indirect effects on an ecosystem.
Drawn to a flame
That old saying, "drawn like a moth to a flame," needs a revision. Many flying insects may appear to be captivated by the glow of a nighttime lamp. But things aren't always what they seem. The reality turns long-held assumptions topsy-turvy. New findings suggest that flying insects are not attracted to the light at all, but actually turn their backs to it. Learn how new evidence challenges old theories and hypotheses while answering questions and discussing how the evidence from such studies supports conclusions.
Unsung Heroes of Science
Throughout history, many scientific discoveries and developments have changed the way we view the world. In this activity, students will learn about some of these important scientific contributions and the lesser-known scientists responsible for them. Students will then choose one of these unsung heroes of science and create an artistic piece that celebrates them and their work and contributions to science. The artistic pieces representing lesser-known scientists will be displayed together in a commemoration open to the school.
