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. LET’S COLLECT DATA
In your notebook, draw a picture of your barrier
Explain your reasoning for building it like you did.
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. 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. 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. 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. 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. 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.
