Knot So Fast / Made in the Shade
AJ invents 'The Lacer Racer,' a shoe-tying car. But, when the car gets out of control, it ties Citytown into knots. How can they build a trap to catch it? Curriculum: A solution can be found by using an engineering design process: What's the problem, what can we try, build, test, and share? / When the ice cream in Stevie Heat's ice cream cart melts, Sparks' Crew investigates how this could have happened, and what they can do to make sure it doesn't happen again. Curriculum: The sun has warming effects. The effect the sun's heat has can be reduced by making shade.
