Classroom Activity, Lesson Plan
Students draw genetic data onto maps and make conclusions about which sheep populations are affected by highways.
Use Science Bulletins videos to explore other examples of disrupted habitats and populations. See how daily life affects wood turtles, seabirds, monarch butterflies, the Gulf of Mexico, Florida panthers, and badgers.
Re-create the 130-million-year-old forest in what is now China to understand why this fossil site is of such vast scientific importance.
"Greenhouse effect" and "global warming" are becoming household phrases but how, exactly, are they linked? Explore the interconnections and consequences of climate change.
Explore the method scientists use to determine evolutionary relationships by creating a coin cladogram. Then try your hand at classifying a handful of dinosaurs.
While refracting and reflecting telescopes use different means of collecting light, the same principle applies to both—the bigger the aperture, the more light collected.
What could Galileo see when he looked through his telescope? Build a refracting telescope with lenses similar to the ones he used, and see the answer for yourself.
What is a telescope's focal point, and why is knowing its location so important to astronomers? Grab a flashlight, an empty soda bottle, and a few other supplies; then find out.
No doubt you've received—or even sent—a digital image. But do you know how these pixel-based photographs work? You will after you decode one yourself.
What would an anthropologist make of your toothbrush, your school locker, or a Halloween jack-o-lantern? Examine the material culture and artifacts of your life.
