Friday: Design a Healthy Day

Rocket unrolls his Healthy Day plan. "Ten minutes of sleep and five hours of jumping!" he says proudly.

Raven raises an eyebrow. "What do you notice? Does it meet the goals we learned?"

Nova projects a checklist in the air. "Engineers test a plan against criteria," she says. "Try it."

Rocket laughs. "Okay, my plan needs a second draft!"

A design problem

Engineers solve problems by designing. First they define the problem.

Criteria are what the design must do to be a success.

Constraints are limits, like time or materials.

Our problem: design a healthy day for Rocket.

Criteria: the plan must...Body systems it helps
Include 9 to 12 hours of sleepBrain, heart, immune system
Include 60 minutes or more of movementHeart, lungs, muscles, bones
Include water through the dayBlood, skin, digestion
Include meals with a mix of food groupsMuscles, bones, every cell
Include handwashing before mealsBody defenders
Constraints: the plan must fit...
Only 24 hours in a day
Time for school, chores and fun
Activities that are safe and use things at home
CRITERIA OR CONSTRAINT?
  • Read the question.
  • Tap your answer.
There are only 24 hours in a day. Is that a criterion or a constraint?
The plan must include 60 minutes of movement. Criterion or constraint?

Test Rocket's first draft

Rocket's first draftDoes it meet the criteria?
10 minutes of sleep?
5 hours of jumping and no breaks?
Water at every meal?
Washing hands before lunch?
WHY THIS EXERCISETen minutes of sleep is far too little. Nonstop jumping skips rest and water.
ROCKET'S BETTER PLAN, MORNING TO NIGHT
  • ?Wake up after a full night of sleep.
  • ?Wash hands and eat a mixed breakfast.
  • ?Walk and climb at the park, with water breaks.
  • ?Wash hands and eat a balanced dinner.
  • ?Calm bedtime, with lights out on time.
WHY THIS EXERCISEA good plan spreads sleep, movement, water, food and handwashing through the day.
What a design must do is called its ____.
A limit on a design is a ____.
Kids ages 6 to 12 need how many hours of sleep, at the least? Type a number.
WHY THIS EXERCISEThe range is 9 to 12 hours, so the least is 9.
IMPROVE THE PLAN
  • Read the question.
  • Tap your answer.
Rocket's plan has no water breaks. What should he add?
Rocket wants 60 minutes of movement. Which plan fits?
Try it
On paper, draw a clock face.
Shade in Rocket's sleep time, then mark his movement time.

Excellent engineering! Tomorrow is our final Body Lab Day. You will make a Body Lab Report.
