Exam Preview for 32327: Exploring Gravity and Balance with Young Ch

Exploring Gravity and Balance with Young Children, in partnership with Region 9 Head Start Association

Please note: exam questions are subject to change.

1. What is gravity? A visible force that pulls all objects down to the Earth The invisible force that pulls all objects down to the surface of the Moon The invisible force that pulls all objects down to the Earth A visible force that pulls all objects down on both the Earth and Moon
2. During the course we conducted an experiment to observe which object would fall first to the ground, a flat piece of paper or a crumbled piece of paper. What did we observe and why did it happen? The flat piece of paper fell to the ground first because it has more surface area. The crumbled piece of paper fell to the ground first because the flat piece of paper has more surface area to fight against air resistance. The flat piece of paper fell to the ground first because it has less surface area compared to the crumbled piece of paper. The crumbled piece of paper fell to the ground first because it has more mass than the flat piece of paper.
3. Why is the concept of the center of gravity an important concept for engineers and scientists to be aware of? Aeronautical, aerospace, and automotive engineers are concerned with the center of gravity because it affects the stability and operations of aircraft, spacecraft, and cars. In sports, lowering the center of gravity increases balance and stability. The center of gravity primarily decides whether a structure will stand or fall over. When designing and constructing structures, prevailing conditions such as wind, waves, and earthquakes have to be taken into account. All of the above.
4. According to what we explored during the course, what is balance? An uneven distribution of weight that allows a person or object to remain upright and steady An even distribution of weight that allows a person or object to remain upright and steady The invisible force that distributes the weight of a person or object to remain upright and steady The invisible force that pulls all objects down to the Earth
5. Which of the following are examples of explorations that teach about the concept of balance that we explored during the course? Have children build structures using a variety of blocks and other building materials to observe the concept of balance. Explore the concept of balance by having children build structures with recyclable materials. Use balance equipment for children to actively experience balance, stability, and develop their coordination. All of the above.
