Create a list of constraints that we ALL

Create a list of constraints that we ALL agree upon ● Review the information in the table below from the Unit Challenge scenario. ○ Does this make a good list of constraints? Are these specific enough? ● Write down your thoughts in your science notebook and then share your ideas with your partner Constraints (Characteristics that the Solution Must Have) Carl’s Original Needs Mary’s Original Needs My constipation has to get better My runner’s trots has to get better I won’t buy expensive or crazy foods; I’ll only use what I’ve got in my pantry I won’t try anything that’s unsafe - nothing I’m allergic to: peanuts and chocolate It has to take 15 minutes or less to make It has to be a smoothie that can be made in a normalsized blender

Which statements are best to include on our list of constraints? Why? ● As a class review the revised set of constraints and compare them to the originals. ● Discuss which are better and why. Record your thoughts in your Unit Challenge Organizer. Constraints Character Original Needs given in the Unit Challenge Scenario Revised Constraints Carl My constipation has to get better Include at least 8 grams of fiber to be able to improve Carl’s constipation Mary My runner’s trots has to get better Include less than 12 grams of fiber to be able to improve Mary’s Runner’s Trots Both Carl and Mary I won’t buy expensive or crazy foods; I’ll only use what I’ve got in my pantry Be made only from ingredients on the Class Pantry List Both Carl and Mary I won’t try anything that was identified in the Unit Opener as unsafe - nothing I’m allergic to (e. g. peanuts and chocolate) Not include anything that Carl or Mary is allergic to (e. g. peanuts and chocolate) Both Carl and Mary It has to take 15 minutes or less to make Will be a smoothie that takes less than 15 minutes to make Both Carl and Mary It has to be a smoothie that can be made in a normal-sized blender Will not include more than 5 ingredients (not counting water or ice)

Criteria for Carl Target: Minimize Weight Gain Ratings 0 1 2 Less than 600 calories/meal More than 800 calories Between 600 -800 calories Under 600 calories Meets Calorie Needs More than 400 calories/meal Less than 400 - More than 400 calories Avoid Extra Fat 11 -20 g/meal More than 20 g Less than 11 g 11 - 20 g Maximize Fiber >12 g/meal Less than 10 g 10 -12 g More than 12 g Minimize Sugar <20 g/meal More than 30 g 20 -30 g Less than 20 g Avoid Extra Protein 16 - 24 g/meal More than 24 g Less than 16 g 16 - 24 g Maximize Tastes great Does not taste good! Tastes ok or good! Tastes great! As a class, do you agree that these are the desirable characteristics and a reasonable rating system? Why or why not? (Make updates in the table above as necessary)

Individually Design a Solution! ● Develop a possible design solution in your science notebooks ● Use the Food Cards to select ingredients ● Use 1 serving size for each ingredient ● Use the List of Constraints to test your design ● Decide: are the Constraints of the solution are met by this design? ○ No? Start Over & develop a new solution. ○ Yes? Share your design with your team.

Design a Solution ! ● Unit Challenge Teams come to consensus on a team design ● Record the details in your Unit Challenge Organizer: ○ the list of ingredients ○ description of how the solution meal meets the constraints Team Design - Initial Ingredients Preparation Measure out and combine all ingredients into a blender. Blend on “Mix” setting for 20 seconds. Check the consistency. If the smoothie is too thick or not blended well enough, add water and continue blending until the desired consistency/texture is reached.

Test Your Design! ● Fill in Solution Meal Nutritional Table for each ingredient using nutritional information from the Food Cards from the Classroom Pantry List ● Calculate totals for each column Calories Fat, Fiber, Sugar, Protein, g Ingredients Banana Totals Serving Size 1 cup # of Servings in Recipe 1 100 g g g 0 3 14 1

Complete the Criteria Rating Table ● Use the Criteria Rating Table and your Totals from the Solution Meal Nutritional Table to determine a rating for each criteria. First Team Design Criteria Target: Minimize Weight Gain Less than 600 calories/meal 1 Meets Calorie Needs More than 400 calories/meal 2 Avoid Extra Fat 11 -20 g/meal 0 Maximize Fiber >12 g/meal 2 Minimize Sugar <20 g/meal 2 Avoid Extra Protein 16 - 24 g/meal 0 Maximize Tastes great SKIP Until Food Expo Score total Ratings 7

Analyze Your Results! Analyze the results in the Criteria Evaluation Table to determine the strengths and weaknesses in team’s initial design. ● What do low ratings signify? ● What do high ratings signify? ● How can we use these to identify the type or amount of ingredient that should be modified? ● How does this analysis help us to work towards a better solution?
