Ms. Sutton wants to build a catapult, but doesn't know how. She wants to build a catapult that will launch a bottle cap 20 feet, but will have to do research to find out how to build one. She only has straws, popsicle sticks, and tape to build the catapult. She also has rubber bands, but Miss Allen says she can’t use rubber bands that aren't latex-free. What is the criteria?

Justina wants to design a water filter that will improve the quality of the water in her town. She first identifies the problem and then starts to build her water filter using a water bottle, sand, and coffee filter. What is missing from this scenario? (Hint: 2 steps are missing)
What is Imagine (brainstorming) and Plan (sketching and gathering materials)?
