Cones
I.SectionObjectives
- Find the surface area of a cone using a net or formula.
- Find the volume of a cone.
II.Cross-curricular-Sculpture
- Students are going to design their own sculpture using different cones.
- These can be cones that they create out of paper, or cones from nature such as a pine cone.
- Begin by conducting a discussion about cones.
- Be sure to review the parts of a cone.
- Tell students that they need to present work to show the surface area and volume of one of the cones that they
create. - Then let them work on their sculpture.
- Students will need paper, markers, colored paper, a surface to build on and glue.
- When finished, allow time for students to share their work.
III.TechnologyIntegration
- Students can go to the following website and look at many different images of cones in architecture.
- http://www.fiveprime.org/hivemind/Tags/architecture,cone
- They need to select one cone to work with.
- Cones of specific buildings are named. Students can use this information to research about the specific cone.
- Students should write a short essay on their cone and draw a design to represent the cone that they have chosen.
- Allow time for students to share their work when finished.
IV.NotesonAssessment
- Assess student work.
- Is the work creative?
- Are the cones accurate?
- Is there anything that the student needs to improve upon?
- Provide students with feedback/comments.
Spheres
I.SectionObjectives
- Find the surface area of a sphere.
- Find the volume of a sphere.
II.Cross-curricular-SpheresforSpace
- Begin with the article on MIT and space spheres.
- Print the article and either have the students read it silently or read it as a whole class.
- Tell the students that they are going to be designing spheres for this space project.
