1. Paper or thin cardboard for animal

2. something to make a slope with

3. Pencil/pen

4. Ruler

5. scissors

• Check out the videos below for some introductory research.

• Start your testing space small. Like in a sink or tupperware. No need to take to seas before we know these things work!

• Experiment with several shapes and several materials. Hint > some work WAY better than others.

• Once you have something that floats on its own, there are 2 directions to go with this challenge.

  1. Cargo. How much can your boat carry without sinking. I like using pennies for this. Can you design a $1 boat?

  2. Movement. Can you design a sail that enables your boat to move on its own? (you'll need to provide a little breeze by blowing). BUT...say you can get it to move, how with you keep it going straight???

You won't need everything on this list, but you might find some of it helpful in your nautical adventures this week.

• Aluminum foil

• Straws

• Sheets of paper

• Pennies

• Tape

• Cling wrap

• Small tupperware

• And anything else you think of along the way!

• And GOOGLE! There are SOOOO many great ideas for these boats out there. Check it out!

This is week is pretty straight forward. Or is it?

• We're going to run three variations of this challenge

• Try each variation with a few times, each time trying to challenge yourself even more!

• Like everything we do, you probably won't succeed on the first try. AND that's ok! What really matters is that you keep trying and be patient with yourself as you improve your skills.

• You'll need a single material for this.

• And you'll want a reliable stacking material as well, so do the first two variations first to learn about the materials you've got around you at home.

• Each step of the way must include a horizontal offset...the means that each new item in the stack must slide over from the previous piece. It can be a subtle move, but it's gotta move!

• How tall can you go?

Well, it helps to have a goal. Like, what is the machine actually trying to do for me? Here are some ideas...

• Drop a bar of soap in your hand

• Ring a bell

• Turn on or off a light switch

• Or...simply build a machine that successfully completes all of its components start to finish.

• A site. Where will your bridge go? Hint...try for smaller spans first...like 8" to 12". We can get bigger once we've got a handle on what we're going.

• Paper. At least 5 sheets to start with. Get creative...cereal boxes, newspaper, old magazines, etc.

• Abutments. The two things that support either end of the bridge.

• Weight. Pennies are my favorite because you can slowly and predictably add weight. But anything will work. Just make sure that each unit of weight is pretty minimal...like...instead of using grapefruits, try using paper clips.

1. How much can your bridge hold?

2. How far can your bridge span?

3. How can you achieve your best results with as few materials as possible? > Hint...this is where it gets super fun!
