Instructions for Side by Side Printing
  1. Print the notecards
  2. Fold each page in half along the solid vertical line
  3. Cut out the notecards by cutting along each horizontal dotted line
  4. Optional: Glue, tape or staple the ends of each notecard together
  1. Verify Front of pages is selected for Viewing and print the front of the notecards
  2. Select Back of pages for Viewing and print the back of the notecards
    NOTE: Since the back of the pages are printed in reverse order (last page is printed first), keep the pages in the same order as they were after Step 1. Also, be sure to feed the pages in the same direction as you did in Step 1.
  3. Cut out the notecards by cutting along each horizontal and vertical dotted line
To print: Ctrl+PPrint as a list

Activity 3: Chemical Composition of Bones and Examining the Effects of Heat and Hydrochloric Acid on bones

front 1

What is one of the hardest materials in the body?

back 1

Bone

front 2

Bone resist what 2 forces?

back 2

1. Tension forces

2. Shear forces

front 3

How would an engineer explain why bone is so strong?

back 3

Many bones are cyclindrical, and a cylinder is one of the strongest structures for its mass.

front 4

How is bone made hard?

back 4

Deposition of inorganic calcium salts

front 5

Where are inorganic calcium salts deposited?

back 5

In the ground substance

front 6

The flexibility of bone comes from what?

back 6

Organic elements of the matrix such as collagen fibers

front 7

What is the effect of heat on bone?

back 7

Heat removes the organic part.

front 8

What is the effect of acid on bone?

back 8

Dissolves out the minerals.

front 9

When treated with heat and acid, do bones still retain the shape of untreated specimens?

back 9

Yes, but the acid-treated bone becomes more fibrous.

front 10

After gently applying pressure to the heated bone & the acid-treated bone, what happens?

back 10

Heated bone becomes brittle and responds to pressure by breaking. The bone treated with acid bends.

front 11

What does the acid appear to remove from the bone?

back 11

Soaking a bone in acid will cause it to lose calcium carbonate, making it very flexible.

front 12

What does baking & soaking in acid appear to do to the bone?

back 12

Baking the bone seems to remove all organic material, making the bone hard and stiff. Soaking the bone in acids seems to remove all inorganic material, making the bone very flexible.

front 13

Which of the bones (acidified or heated) specimens would more closely resemble the bones of a child with rickets?

back 13

The bone treated with acid.
