Upload a picture showing how you are testing your Strong Boat. Be sure your picture shows 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!!

Engineers work hard over time to improve designs. Making changes to a plan is how we create the best designs. Please upload a picture of your NEW Strong Boat plan here.

(You can receive up to two more 20-point badges for your Strong 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!

Engineers use data to improve designs while they test. Upload a picture of data you can use to improve your tall boat.

Now you have great data! Some data you found may not be numeric. It may be how your boat sat in the water, how it looked with different amount of weight in the boat. This data is important too!

Use all the data you have to plan an improved design for you boat. You can click here to upload a new plan of your boat.

Describe the steps that you will use to test your solution. It may be only two steps, or you could describe how you will continue to improve your boat. You may want to use light things to start testing your boat.

Either way, you will earn 15 points for each test of your Strong Boat designs. This badge can be earned 3 times for 3 different tests.

Engineers make changes after testing designs. Describe the most important change you made while testing solutions for your Tall Boat.

(You can earn this badge 1 time, and it’s worth 30 points. You should describe how you used data to make this improvement in the area below.)

Great work completing your Tall Boat engineering challenge!! Click here to earn 150 brainpowers for your successful building adventure.

Think about everything you did! There were successes, problems, solutions (and then more problems!). You kept working hard and got to the end. Nicely done!

We will be updating this page with successful boats. Here are some of our favorites so far! If you want your here, scroll to the bottom and upload a picture of your Tall Boat.

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.
