Coastal and Marine Geology

Science Fair Project Idea

Scientific Method

You can study hazards that affect coastal areas. What geological forces cause a tsunami? A tsunami (Japanese for 'harbor wave') is a wave generated by an undersea earthquake, landslip, or volcanic eruption. You can demonstrate what causes a tsunami by simulating an undersea earthquake with a water table. How does the depth of water effect the height of the wave? Do different slopes of bottom change the speed of the wave? Visit the USGS Coastal and Marine Geology Program to find out about… Read more

Coffee Buzz: How Does Caffeine Affect the Physiology of Animals?

Science Fair Project Idea

Scientific Method

Caffeine is a type of chemical called a stimulant. When you drink a caffeinated beverage, the caffeine enters into your blood stream dilating the capillaries and causing blood to flow more quickly. This gives your body a feeling of speeding up which can cause the jitters and wakefulness. How does caffeine affect the physiology of other animals? You can use over-the-counter caffeine supplements, like Vivarin, to test the effects of caffeine on animals. Try dissolving the caffeine in… Read more

Collide Head On with this Toy

STEM Activity

Did it ever occur to you that tennis, bowling, Newton’s cradle, and cars bumping into each other all revolve around collisions? It is fascinating how a few rules of physics can predict the outcome of these collisions. You can discover these rules yourself with a fun homemade toy. Do the activity, play with the toys you make and be one step closer to understanding what happens when you shoot a marble into another! Read more
