Interactive video lesson plan for: Change of linear dimensions impact on surface area and volume

Activity overview:

If you change the linear dimensions of an object,how does this change the object's surface area and the volume?
Video Guide Spheres and Proportions
0:01 Introduction to Radius Diameter-Area-and Volume, and the relationship of linear measurement and volume.
1:18 If you had two spheres with a ratio of 1:3 what does this ratio look like with area and volume?
2:26 What if the ratio is 2:5 ? What is the linear measure ratio,the
area ratio, and the volume ratio?
3:07 Example 3 What if you are given the area ratio, how do you find the linear measure, and the volume ratio?
3:57 Example 4 What if you are given the volume 1:8.how do you find the linear and area ratio.
4:30 Example 5
5:02 Example 1
A balloon has a radius of 6 inches. Describe what happens to the balloon's surface area if the balloon inflates and the radius changes 12 inches.
5:46 Problem 2 Describe what happens to the same balloon's volume if the radius is doubled.
6:10 Problem 3 A sphere has a radius of 4 inches. What happens to the spheres volume if the radius is halved.
6:12 A sphere has a radius of 8 inches. What happens to the sphere's surface area if the radius is halved?
7:31 Fill in a table that has..
When the radius is doubled,what is the area, and what is the volume.
