You made it to the end of this challenge! Click here for a 150 point badge celebrating your Tall Boat engineering.

While building and improving your tall boat, we hope you saw how gravity pulled down on the boat. You had to balance where water could push up on your boat against the force of gravity pushing down on your boat.

Some people think about this boat in two parts. One part is the bottom which makes a sturdy base. The second part is a tower that reaches for the sky. Engineers think about designs in parts too. Thinking about different parts is called Systems Thinking. A system accomplishes a specific goal. In your tall boat, one system made the boat float and another system made the boat tall.

You can upload your final Tall Boat picture here if you want to show off your designs to other people.

Great work with this challenge!

One more drawing! This is the last time you can earn a Planning Badge, but please don’t let that stop you from continuing!!

Engineers take dozens, and sometimes hundreds, of design steps before finalizing a design. You can continue to push your boat design until it reaches the sky! Upload a picture of your third drawing for planning a tall boat.

We hope it has become easier and easier to continue designing ships. We hope your designs became clearer and more useful!

You can upload one more table or graph of your data here. Think about how your data has changed since you started. Do you collect new types of data? Do you think someone else could read your data and know what it means? Engineers use data to show why they make changes. You can collect and use data for all types of designs!

Think about what worked well for getting this data. You can use those strategies again for the next challenge!

Let’s see one more test! Share one more picture of your testing. This final picture should highlight some of the changes you made since your first design. We want to see how much problem solving you have been doing!!

By now, we hope you are having fun changing and testing your boat. Keep going forward! If you want to send us more pictures, you can tag us on Facebook, connect on Instagram, or simply upload another picture on this website.

Thanks for working so hard! You are engineering very well. Time for one more data badge.

Data Gathering: How tall is your ship? How wide is your ship? What is the area of the bottom of your ship?

Use this space to record data you think is important for describing your Tall Boat.

Let’s see your second design! Upload a picture showing how you are testing your Tall Boat. Be sure your picture shows the changes you made in your boat design.

We may share your boat picture with other people if we think that they can learn from your process or your design. Your boat may be famous!!

New drawing! Engineers work and work to improve designs. Making changes to a plan is how we create the best boats! Create a new drawing that uses the lessons learned from your first tests. Please upload a picture of your NEW Tall Boat drawing here.

(For the Points Collectors: You can receive up to two more 20-point badges for your Tall Boat plans. You must go through the process 3 times to receive all 3 badges.)

After you complete this step move on to Testing Your Ship!

You can build a robotic hand using the kit provided. We have two challenges related to this building adventure:

1. Make a hand that has five moving fingers.
2. Make a robotic hand that can hold up a full water bottle (or 12-ounce can).

We love this video providing additional resources about the building and design processes:

When you build a tall boat, what data should you measure to see how tall it is? Upload a picture of your data collection (e.g., table, graph, etc.).

Challenge 5: Build a boat that can hold an empty bottle in heavy waves.

Engineers draw plans to help them think. Try to draw your boat from two different views. Upload a picture of drawings you used to plan or improve your boat.

Does your boat have a system for holding an empty water bottle? Many students have found that system is useful.
