Got your catapult? How’s your GAME?

If you built your cardboard catapult last week, join me on this week’s video and learn how to use a simple PLAN–DO–CHECK–ACT design cycle to improve your game!

My challenge to you this week: 

Given a range (distance) to your target, can you tune your catapult & projectile to hit your target?

(Hint: you may want to do a few tests and collect some data. My website has a sample data sheet and blank chart you can use to plot your data up. It might help you figure it out.)

Here’s a few links you may find useful:

Or check out the catapults page on my website (under the STEM menu) for more ideas:

How do you like the game you created with your catapult? Anything you’d change to make it more fun?

Any questions? Join me this Saturday, November 14th at 1:15 pm on my Facebook Author page to post any questions you have. I’ll be online to answer questions. Who knows? Maybe I’ll even do a quick Facebook live video with some new game tests.

I would love to see how your catapults turned out. Feel free to post photos to my MK Tufft author page, or go to my website, and upload a photo or link to a video of your catapult for a chance to win an autographed copy of one of my books. Just scroll down to the bottom of my catapults page where it says “Submit a photo or video of your experiment.”

Join me next week for more insights on how catapults work, and how to improve your designs!
