The Search for 3D Solids!
The
world around us if filled with 3D solids!
In this unit we will identify and classify 3 dimensional figures
according to their attributes (attributes like the number of faces, vertices,
and edges the figures have), and search for real world examples of these
exciting shapes! You will also
have the opportunity to take pictures of 3D solids in your own home. Let’s begin our solid search for some
real world 3D shapes! Remember, 3D
solid is a figure that has a length, width, and a height. It is something that you can hold, and
that takes up space! The first
solid we found on our solid search is the cube! This cube is unique because it has 12 edges that are all the
same length! The cube also has 6
flat faces, and 8 vertices. Can
you think of any cubes you have in your classroom? Next on our solid search we found a cone! A cone has a circular base and one
vertex. You can find cones when you are at a birthday party, getting an ice
cream from the ice cream man or even
while supporting Lamar! Here’s a cylinder! A cylinder can roll on its curved side,
or stand tall on one of its 2 flat faces.
Where can you locate a cylinder in your house? Next, is a solid that can be found in any sporting
event. The sphere! This special solid has no faces, edges,
or vertices. It can roll, bounce,
or be thrown through the air!
Finally, we found a rectangular prism! This solid is very similar to the cube. As you can see, it also has 12 edges, 6
faces, and 8 vertices. There are
rectangular prisms all over! How
many can you locate in your room?
Now, it is your turn to locate as many different 3D solids in your own
home! Use a camera to document
your solid search so that you can share your findings with the class. Good Luck, and we can’t wait to see
what solids you have in your everyday life!
