### Cell barrier building

1. 1. Building a better wall
2. 2. LET’S PLAY! You and your partners need to build a barrier to protect your object. The barrier needs to be solid so that nothing can get in or out. You also need a flag/marker to identify your barrier and to make it stand out from the other barriers being built in class. You are to use only the materials found in your bag. You have 10 minutes GO!
3. 3. LET’S COLLECT DATA In your notebook, draw a picture of your barrier Explain your reasoning for building it like you did.
4. 4. Observations: Compare your barrier to the table next to you. On the same page of your notebook, explain how your two barriers are the same and how they are different using a T-chart. Similar to other Different to groups other groups
5. 5. Making it more complicated… Now you have to modify your barrier to allow rice- man in and out. The opening should be just big enough for rice man.
6. 6. Let’s collect more data In your notebook, modify your original picture to show how rice man is getting in and out. Answer the following:  How does this compare to other group modifications?
7. 7. Getting even more complicated…. Now modify your barrier to allow bow-tie man in. Bow-tie man can’t use the same opening as rice-man. Devise some way to let bow-tie man know where his opening is (he has poor eye sight and needs lots of help). You might try a signal/marker of some sort.
8. 8. Collecting the last data…. Modify your drawing in your notebook to show how bow-tie man gets in and out. Make sure to draw in your marker/flag for him. Now do a gallery walk and see the barriers built by other groups. Write down 2 barriers you like and why. Write down 2 barriers you didn’t like and why.
9. 9. Voting Now you will have to vote for the best barrier design in class. The best barrier will be saved, the rest will be dismantled.  Take apart your barrier. Any materials that can be reused, return to your teacher.
