This science journal entry explores fundamental science vocabulary and concepts related to forces, focusing on sound, light, and gravity. Key vocabulary terms include "sound," defined as repeated vibrations that animals can hear, and "light," which pertains to electromagnetic radiation associated with vision. A guided question illustrates the principle of gravity, which is the force that pulls objects toward the Earth, as demonstrated by a falling fork. This entry helps solidify understanding of essential scientific terms and concepts.

10/2/2012Guided Question32 A fork falls off the edge of a table. Which force moves the fork toward the floor? F The pull of Earth’s gravity G The pull of Earth’s rotation H The push of the table J The push of air pressure
All objects are pulled to the center of the planet through a force called gravity. So when an object falls off a table it is the pull of the Earth’s gravity that makes it fall to the ground. The Answer is F The pull of Earth’s gravity
