This Week's Highlights
Transportation unit is finishing up this week! Students will present and receive feedback next week in order to ensure that you are able to see an amazing finished product during the open house!
For our next unit we need the following supplies, if you are able to donate any of these materials it would be extremely helpful:
Play-doh
Straws
Activated charcoal
Cotton Balls
Empty 2-Liter Bottles
Sand
Gravel
Pantyhose

In the beginning of our next unit, your scholar will be thinking about the surface area and volume of three-dimensional figures. Above is a triangular prism. Its base is a right triangle with sides that measure 12, 12, and 17 inches.
Solution:
In general, we can find the volume of any prism by multiplying the area of its base times its height. For this prism, the area of the triangular base is 72 in 2, so the volume is 72⋅14, or 1,008 in 3.
To find the surface area of a prism, we can find the area of each of the faces and add them up. The example prism has two faces that are triangles and three faces that are rectangles. When we add all these areas together, we see that the prism has a total surface area of 72+72+168+168+238 or 718 in 2.
Here is a task to try with your scholar: The base of the prism above is a hexagon where all the sides measure 5 cm. The area of the base is about 65 cm2.
- What is the volume of the prism?
- What is the surface area of the prism?
Solution:
- The volume of the prism is about 1,040 cm3, because of 65⋅16=1,040.
- The surface area of the prism is 610 cm2, because 16⋅5=80 and 65+65+80+80+80+80+80+80=610.
