Math and Measurement in Engineering

How does Math Help?

• We measured the supporting strength of the straws in our experiment

• We also determined a rule that described how the straws behaved.

Poll

Math is everywhere!

• True

• False

A lense gathers and refracts light. Math can describe how the light bends

Multiple Choice

Light can bend and math can help us describe why.

• True

• False

This tool measures how much stretching force steel can handle.

This property is tensile strength.

These solar cells capture energy from the sun. The meter measures how much energy is transformed to electricity.

Poll

Do you think we should use solar cells to heat our houses?

• Yes

• No

• It depends on where your house is

• I need to learn more before I can answer

Watch this 3 minute video. Be sure to listen for the problem that Hubble experiences and how the scientists and engineers work together to fix it!

Multiple Choice

What is the problem with the Hubble space telescope?

• It was too far away

• The lense made things blurry

Multiple Select

How did the scientists and engineers fix the blurry vision? Mark all the answers that are correct

• The scientists and engineers worked together.

• They tested the devices on Earth

• The developed the devices on Earth

• They added optics that acted like human eyeglasses.

A person with healthy eyesight has 20/20 vision.

If you have 20/100 vision, it means that what healthy eyes can see at 100 feet, you can only see it at 20 feet.

Multiple Select

A person with 20/100 vision has healtier eye sight than that of a person with 20/20 vision.

• True

• False

Fill in the Blanks

If someone has 20/10 vision, what others see at

feet , that person can see at 20 feet, which is better than normal.

Multiple Select

True or False: science, math and engineering worked together to make the repairs on the Hubble telescope happen.

• True

• False
