You can learn more about rotations by visiting this website. **What other objects have rotational movement? **Discuss rotational movement of the earth, planets, moons, tires, etc. **How do you think the speed of these objects is calculated?

If so, why do you think that is? • Pay attention to how the colors of the horses are dispersed throughout. • Listen to the type of music that plays as the carousel is moving. • Be sure to take note of these details so you can reference them later.

Arts Connection: Carousel Creations In this lesson, students will: **Examine the equine sculptures that are part of the Carousel at the State Fair of Texas. **Design their own version of a carousel, based on their experience at the Fair. **Present and defend the creative choices they made with their classmates regarding their carousel design. TEACHER The Midway & Games Speeding Around Grade Five Determining the Speed & Energy STEM of The Dentzel Carousel While You’re There Refer to the main lesson for instructions.

Before You Go Discuss with the students some of the history of the carousel at the State Fair. **The carousel caretaker dates it back to 1924. **National Carousel Association says parts of it could have been made as early as 1914. **It is one of six classic carousels in Texas and one of 275 in the nation. **It was brought to Dallas in 1951, and remains one of the favorite rides of fairgoers today. **Each of the animals is hand-carved and painted. They are all horses. **This link from the website of The National Carousel Association contains wonderful close up images of horses on the carousel at the State Fair. As you click through the images with your class, ask them questions, such as: * What do you see in each of these horses? * How are they different? * How are they similar? * Also, discuss how the artist has utilized color and balance. Why would that be important in this work?
