Evaluate Your Design

Teacher Note

Work with groups as they figure out how to refine their design to meet the new price point and respond to constructive criticism.

Read More

Evaluate the feedback from your fellow students. What did they like and dislike about the graphics and text? To what extent did they understand the message? Was there a consensus about what students would be willing to pay for your T-shirt? Answer these questions on page 15 of your Engineering Portfolio.

Some consumers are willing to pay more for eco-friendly clothing, but others are not. In order to appeal to more customers, ensure that your T-shirt can be produced for $17 or less. Using your evaluation and this new criterion, describe how you will refine your design on page 16 in your Engineering Portfolio.

Next, use the design tool again, and make changes as needed to appeal to customers and meet your new price point.

Hint

Use this chart to help guide your selection.

Options Environmental Impact Other factors to consider
Organic Cotton
  • partially watered by rain and supplemented with irrigation
  • harmful chemicals are not used to deal with weeds and pests
 expensive to produce
Hemp
  • does not require excessive water or pesticides, but is generally grown overseas and must be transported to the U.S.
  • transportation uses fossil fuels, which release greenhouse gases
 fabric is rough, wrinkles easily and color is often not rich
Bamboo
  • grows quickly with little water and does not require pesticides to thrive
  • takes more energy and chemical processing to turn bamboo into soft fabric
 expensive to produce

Color will not affect the cost of your T-shirt.

Use this chart to help guide your selection.

Options Environmental Impact Other factors to consider
Vegetable dyes
  • made from plants
  • require lots of water to use
  • contain fewer harmful chemicals than traditional dyes
 expensive to produce
Low-Impact dyes
  • contain no or few toxic chemicals
  • can be used at a low temperature, meaning less energy is used to heat the water involved in the dying process
 fabric is rough, wrinkles easily and color is often not rich

Think about the message you want to convey. Which graphic best helps to convey your message or cause?

If graphics cost $0.01 per square inch, you need to first obtain the product of the dimensions. Next, multiply the product by $0.01 to obtain the cost of the graphic.

For example, if the dimensions are 5 inches by 5 inches, you would find the product:

5 x 5 = 25

Next, multiple that product by the unit cost.

25 x $0.01 = $0.25

The cost of a graphic that is 5 inches by 5 inches is $0.25.

Choose accents that will complement your T-shirt center graphic. Remember to leave space if you choose to add text to your T-shirt.

Identify the number of accents that appear on your T-shirt. Multiply the number of accents by $0.02 to obtain the total cost of accents.

Think about your cause. What text would best convey your message? Remember to keep track of costs and the number of letters used.

Up to 20 letters is $1. Each additional letter over 20 is $0.06. If you have more than 20 letters, multiply the number of additional letters by $0.06. Next, add that product to $1.

To find 1% of the sum, multiple the sum by 0.01. Round to the nearest cent.

Use this chart to help guide your selection.

Options Environmental Impact Other factors to consider
Domestic manufacturing (made in the U.S.) minimal energy used in transportation higher labor costs
Overseas manufacturing more energy is used in transporting goods from oversees, which contributes to the release of greenhouse gases lower labor costs, but companies must pay additional taxes and shipping costs

To find 2% of the sum, multiple the sum by 0.02. Round to the nearest cent.

Use this chart to help guide your selection.

Options Environmental Impact Other factors to consider
Made with no recycled materials may take more energy to process materials
  • may have negative impacts on the environment
  • is not eco-friendly
  • may require more effort or expense
Made with some or all recycled materials
  • may take less energy to process materials
  • diverts some materials from landfills
 may require more effort or expense

Find the sum of all items in Your Choices so far. Next, multiple the sum by either 0.02 or 0.04, if you chose to use eco-friendly practices.

Now that you have an idea of how much your T-shirt costs to produce, decide how packaging will affect your cost.
