2. QUESTION Does salt water or lemon juice have any effect on the rate of dehydration of different types of apples.

3. prediction I predict salt water will have the effect on the rate of dehydration because the water content of apple are retained with the presence of salty water.

4. Material • Salt water • Lemon juice • 6cups • A knife • 1red apple,1green apple, and 1golden apple • Some water • A weigher • A clock/time

5. variables independent: the shape of the apple. Dependent: the dehydration of the apple. Controlled: the cups, the knife and the weigher.

6. Procedure • Gather all materials. • Cut the red, green and golden apples 4 equal slices. • Weight the red green, and golden apple slices ,separately. • Pour water into a cup, then add ½ a cup of salt. • Split the different apple slices in half, dip 1 half into the salt water and the other into the lemon. • Let it rest for 5 minutes. • Then weigh again and write down the data. • Repeat steps 5,6 and 7 2x7 but don’t repeat the part split the different apple slices in half.
