We have been talking about the many different kinds of weather we may experience. We also discussed how the four seasons each have certain types of weather. What about storms. What kind of storms are there? Thunder storms, hurricanes, tornadoes, blizzards, and sandstorms are some different kinds of storms. A storm usually brings very strong winds, called gales, that are often accompanied by other bad weather like heavy rains or snowfalls. Small storms may last just a few hours and some large storms can last for days and cause damage to an area and its buildings. Hurricanes are powerful storms that may be hundreds of miles wide with very very strong winds. A blizzard is a type of storm that has a lot of snow fall with strong winds. Sometimes, the wind sends giant clouds of sand or dust racing across the desert. This cloud, called a sandstorm, is so rough it can rub the paint off cars in just a few hours!
Thunderstorms happen when a cumulonimbus cloud forms in the sky. Strong winds inside the cloud swirl rain, snow, and hailstones up and down. This makes electricity build up It escapes down to the ground as flashes of lightning. Thunder is the sound that lightning makes when it heats up the air around it. You always see lightning before you hear thunder, because light travels faster than sound. What about tornadoes? Tornadoes are violent, whirling winds. They are sometimes called twisters. This is a whirlwind that forms below a thunderstorm. The air inside a thundercloud slowly begins to spin around and around. The air spins faster and faster and the cloud begins to change shape. This cloud touches the ground and as it moves it destroys everything in its path. Tornadoes can be scary. People who live where tornadoes happen often have a special plan of where to go to help them be safe when a tornado is coming.
We can try to make a twister, or tornado cloud in a bottle. Here are the things we need. Demonstrate activity for cyclone in a bottle.
Need for lesson - A percussion instrument, the book, "The Story of the Orchestra", CD player, and pictures of percussion instruments.
We are going to talk about the family of percussion instruments. The percussion instrument makes sound when it is hit, shaken, or scraped. Drums are a kind of percussion instrument that are hit with drum sticks, to make sounds. Let's look at some other kinds of percussion instruments. Look at the tambourine, what do you think is used to play this instrument; is it hit, shaken, or scraped? It takes a lot of practice to play a percussion instrument because you have to hit it with the right amount of strength, in the right place, and at the right time.
In the orchestra, the percussion family is the largest group of instruments played. The xylophone, timpani, cymbals, triangle, snare drum, bass drum, tambourine, maracas, gongs, chimes, celesta, and the piano are the percussion instruments in an orchestra.
Demonstrate the percussion instrument or instruments and allow children to try them.
Today discuss the percussion section of the orchestra and play which tracks on the CD you like.
