yTeach Blog Assignment for
Please complete the yTeach lesson found at this link: Floating Bodies.
As you complete the lesson, answer the following questions and post your answers as a comment to this blog. Some of the yTeach lesson is a little bit above your grade level, but be patient and rewatch the movies if you need to, or look up words if you need to.
1. kg m-3 means "kilograms per cubic meter" and is a way of representing density similar to "grams per milliliter" or "grams per cubic centimeter". On the second yteach page, you are shown the densities of different objects, and the densities of different liquids. Under what conditions will the objects float?
2. What is Archimedes principle according to the video on page 3 of the yTeach lesson?
3. According to the video on page 4 of the yTeach lesson, what is the importance of the weight of the water displaced by an object?
4. On page 5B of the yTeach lesson, what is the volume of the cuboid if 1 cubic meter (m3 is equal to 1,000,000 cubic centimeters (cm3).
5. On page 7A of the yTeach lesson, you observe the affect of salinity (salt in the water) affects ocean vessels. Under what conditions do objects float the best?
