Grade K Pacing Guide: Forms of Energy Sound/Practice of Science Benchmarks SC.K.P.10.1: Observe that things that make sound vibrate. SC.K.N.1.1: Collaborate with a partner to collect information. SC.K.N.1.2: Make observations of the natural world and know that they are descriptors collected using the five senses. SC.K.N.1.3: Keep records as appropriate - such as pictorial - of investigations conducted. SC.K.N.1.4: Observe and create a visual representation of an object which includes major features. SC.K.N.1.5: Recognize that learning can come from careful observation.
3
How does sound happen? What causes sound? What is sound?
4
What are the vibrations that make sounds? All sound is made up of vibrations (rapid back- and-forth movements.) The vibrations that make sounds travel like ocean waves in back and forth motion.
5
Hiroshige’s famous painting, “Wave off the Coast of Kanagawa,” allows us to imagine giant ocean waves that are similar to sound vibrations. Department of Science
6
What are vibrations? Vibrations are forms of energy that move back and forth. Vibrations can move through: Solid Liquid Gas SOLID LIQUID GAS
7
What makes the sounds of music? Musical instruments such as guitars, pianos, and violins, make music as their strings vibrate. Make your own music! Place a rubber band around an empty, uncovered plastic container. Pluck the strings! What do you hear? Department of Science
8
Would you like to make a musical instrument that you can play by making sound waves that travel through the air to your ears? Your teacher will help give you directions. Have fun with your “kazoo”!
9
Are sound vibrations always the same? What do you think? Is a train whistle louder than a cat meowing? Is a bird singing as loud as a lion roaring? Is a football game softer than a baby laughing? Is a rain shower as soft as a birthday party? Can you think of other loud and soft comparisons? Do you agree sound vibrations are different!
