Design Your Team Bridge

The second step to the Design Process is to create a design or blueprint of h= ow you would like your bridge to appear. Use this organizer to create a scientific drawing of what you think = your bridge should look like when you are finished. Keep the materials you will be usi= ng in mind as your draw and label your work.&nbs= p; As you create your drawing, keep the following in mind:

· = A scientific drawing shows the details of what I observed.<= /p>

· = All parts of a scientific drawing are labeled.

· = A scientific drawing is large enough to see all parts clearly.

Student Safety Con= tract

All scientists- like you- are careful when they work. You need to be careful in science, too. Here are some safety tip= s you should always follow:

1.&n= bsp; Before you do an activity or change anything about the directions, you must get the permission of your teacher.

2.&n= bsp; Read all of the directions before you start. If you do no understand them, ask an adult for help. =

3.&n= bsp; Follow the directions carefully. It may be helpful to check off the directions that you already completed so that you = can keep track of your progress.

4.&n= bsp; Obey all safety instructions that may be included as part of the procedure.

5.&n= bsp; Always wear goggles or an apron when the instructions tell you to.

6.&n= bsp; Never taste anything unless your teacher say= s it is ok. Do not touch your eyes= or mouth while you are working with plants, animals, or chemicals!<= /span>

7.&n= bsp; Be extra careful when using cutting tools or sources of heat.

8.&n= bsp; Always clean up spills right away. Ask your teacher where you should dispose of the liquid.

9.&n= bsp; After you have completed the activity, clean= up and put things back where they belong.&nbs= p; Wash your hands, if possible.

I promise I will take my work seriously and follow each of the rules for scie= nce safety.

Research the Types= of Bridges

The first step in the Design Process is to research your topic. Use this graphic organizer to find= out more about the different types of bridges engineers may choose to build.

Each engineer in the group will research one type of bridge and then share the information they find with their group to make a final decision about the t= ype of bridge to build.

Click on a link wi= th your bridge name to draw a sketch of the bridge and to write at least 3 fac= ts.

Part 2= : Use the pictures on the site = Part 3: Use the information

to sketch what your bridge looks like. from the site to write at least

Part 4: Name the three forces that affect all bridges.

Data Collection

The last steps in the Design Process is to Review and Modify<= /span> your work. Use th= is graphic organizer to collect data about the Build A Brid= ge competition. As each group pr= esents their work, record the information in your chart so that you can make conclusions about the types of bridges and weight.

If the group followed the listed guideline for their finished bridge, write “yes” in the column. If they did no follow the guidelines, write “no” in the column.
