Animals and insects build structures for many reasons. A wonderful example of good engineering is that done by a honeybee. Draw an illustration of their structures and discuss the geometry that you see in its design. Why is this a good example worth investigating? What properties does it have that influence its strength? Bees create a chamber of vertical of six sided hexagon looking cells. All the bees work together to make a hive of hexagonal cells. It is worthy to investigate because bees know the exact angle to build at.
Spiders create spider
webs by weaving them and attaching them to something. There are
strong because bugs get caught in them and stay to give them
nutrition. Although someone could come by and destroy the web
altogether.
I found that the
strongest shape under compression was the tringle.The strongest
under tension was the rectangle.
What other questions do you want to find answers to while working
on this project?
After working with the journalist in your group, get a copy of the interview questions and the name of one person to interview. You will need to complete an interview worksheet for the interview that you do and attach it to your research notes and turn it in with your report. |

Interview I interviewed my dad Bruce Dillman. He told me that corrugation would help within our cylinders since we are trying to build for strength. He also had said that we needed a strong base to hold the weight but also we needed it to be strong throughout the whole structure for reinforcement. He was very helpful in giving us ideas to work with. |

| Our
design was 11 1/2 inches and withstood 180 pounds. It was suitable
to meet the height and weight of the criteria for the project but
once it started leaning one way the whole thing went down. I think
if we balanced the weight on the top of the structure better, than
our structure would of held a lot more weight than it did. Some
benefits to our design though were that we had in the cylinders
inside the structure. Also, our walls were pretty strong and so was
our base. We used a lot of corrugation and shapes inside of other
shapes to make sure that everything was really strong. A weakness in
our design was the leaning of the structure, if it didn't lean then
it would not of fell so fast. We should of made sure that every
little piece was equal and even to the other pieces and to the base.
Overall it was a good, fun experience that put your mind to work and
made us really think about the concepts of geometry.
