A Coral Reef Food Chain: A Who-Eats-What Adventure in the Caribbean Sea

Welcome to a Caribbean coral reef! As you snorkel simply offshore, you notice extraordinary fish, waving sea anemones, diving turtles - even perhaps a prowling barracuda! The coral reef is filled with lifestyles - from coral polyps snagging plankton to a moray eel gobbling up a goby fish. Day and evening at the coral reef, the search is directly to locate foodstuff - and to prevent changing into an individual else's subsequent meal.

He also noticed that when a force acts on an object, that object accelerates positively or negatively (speeds up or slows down). Sometimes accelerations are not easy to detect. In order to better understand acceleration, you may build an accelerometer. It will indicate the direction of the acceleration as well as its presence. 1 How to Build an Accelerometer Materials: an adult carpenter’s level tall pill bottle with cap water soap thread pin cork or piece of Styrofoam tape jar with screw-on cap You can use a small carpenter’s level as an accelerometer, or you can build something similar by filling a tall pill bottle with water (see Figure 12).

You probably already have but just did not know it! Perhaps you are reading this book because you are looking for an idea for a science fair project. Maybe you want to learn about Newton’s three laws of motion. This book will provide an opportunity for you to understand the concepts of friction, acceleration, buoyancy, gravity, the Coriolis force, centripetal force, and more. You can have fun working with bowling balls, pendulums, levers, toy cars, rockets, marbles, and bicycles. Doing the experiments will help you learn about the science behind some everyday things.

This is because the descending ball with the greater acceleration exerts a greater force on the gutter ball. When the descending ball goes with a higher velocity than before to the point of impact, it goes with a greater acceleration than before. A greater acceleration for the same mass means a greater force. That is why the faster descending ball makes the gutter ball move away faster. Why does the descending ball stop? Only a force acting upon it could have stopped it. That force could only have come from the ball in the gutter.
