Growth+and+Development

Group Members: Carly Putterman Kat Kaplow Matt Saidel Becky Maher

Materials:
 * petri dish
 * Seeds
 * unknowns A,B and C
 * Dropper
 * damp paper towel
 * hand glass

Hypothesis: If the unknowns, either A, B, or C, are living then they will grow and develop over time.

Procedure: 1.) Get petri dish 2.) Cut a circle out of a paper towel 3.) Dampen the paper towel using the dropper and place it inside the petri dishes 4 .) Get a hand glass 5.) Put each unknown in its own petri dish 6.) Put seeds in petri dish 7.) Watch then grow and develope over time

Observations: Day 1: Unknown A- stayed the same Unknown B- absorbed some water Unknown C- blended into the paper towel Seeds- turned into a lighter brown but stayed the same size

Day 2:

Unknown A- Stayed Same Unknown B- Absorbed wate r Unknown C- Blended into the paper towel Seeds- Started to grow roots and leaves

Day 3: Unknown A- Stayed the same Unknown B- Absorbed even more water and got bigger Unknown C- It absorbed into the moisture on the paper towel Seeds- The roots got longer and leaves got bigger and greener

Conclusion : Only one unknown showed a sign of growth and development, unknown B. It got bigger and absorbed water over the 3 days. While the other remained the same. Showing that they are not living.
