1b. Bone up on calcium
Project skill: Discovering the importance of calcium for bone stregnth
Life skill: Using scientific methods

1. Which bone bent easily? Why?
The bone soaking in vinegar bent easily because the vinegar dissolved the calcium out of the bone. Vinegar is an acid. Calcium makes a bone hard, so when it is removed, the bone bends easily.

2. Which part of the bone became soft first?
The ends of the bone become soft first because it is the growing end of the bone which is "softer" due to the nature of the cell structure.


3. Why did you have one bone in the water and one in vinegar? Which one was the control and which one was the variable you changed?

Water does not dissolve calcium, so it provides a measure, or a means to compare how much another liquid affects bone hardness. The bone in the water is the control. The bone in the vinegar is the variable, or the one that was changed.

 

1c. Fruit kabobs
Project skill: Creating fruit kabobs
Life skill: Making healthy lifestyle choices

1. Why did you put the slices of banana in the lemon juice?
The banana slices are put in the lemon juice to slow down the browning that occurs. The browning occurs due to an enzyme called polyphenal oxidase. When air touches this enzyme, the banana turns brown.

2. What vitamins are in the fruits you used for your kabob?
Vitamins include Vitamin A, Vitamin B-6, Vitamin C, Vitamin E, Niacin, Thiamin, and Riboflavin.

3. Name three other foods not used in your kabob that contain Vitamin A or C.
