 * Question #1**
 * In the beginning of the spring, it seems everyone is caring for their front lawns by sprinkling fertilizer to help the grass grow better? Does fertilizer really help the lawn grow better? **

What Kind of fertilizer are they using? How much does it rain in that area? How large is the lawn, and what flowers grow there?
 * a) Ask a question a scientist might ask given this information. **

Yes, it might. The fertilizer has some added chemicals to enhance the grass' growth.
 * b) Write a possible hypothesis for this experiment. **


 * c) Design an experiment to help answer the original question. **


 * Track one lawn with fertilizer for a week and take pictures and measure and collect data and then compare tour findings with a garden with no fertilizer. **


 * Describe or draw four possible groups in your experiment – **


 * d) What is the manipulated variable? **
 * The color of the grass, the height of the grass, the lushness of the grass. **


 * What variables are being kept constant? **
 * The soil and the water given **


 * What is the control group in your experiment? **
 * A lawn with no fertilizer **


 * What will you be measuring to include in your data table and graph? **
 * The hight of the grass **


 * How will you measure the differences between the 4 groups? **


 * e) Write a conclusion for the results below: **

Kidney Bean Plant Growth (cm)
 * || no fertilizer || 3 cups of fertilizer ||  ||   ||   ||
 * Plant 1 || 12.5 || 13.6 ||  ||   ||   ||
 * Plant 2 || 10 || 12.5 ||  ||   ||   ||
 * Plant 3 || 13.6 || 14.3 ||  ||   ||   ||
 * Plant 4 || 11.2 || 15.7 ||  ||   ||   ||
 * Average ||  ||   ||   ||   ||   ||

Make a graph for the data above:

Question #2 How did each lab this year help us better understand science concepts:

A. The Paper Airplane Lab

B. The Xpult Lab Showed us how important variables were

C. The Mixture Lab

D. The Baking Soda Lab (Ultimate Fizz) Variables and Constants

E. Making Chalk Lab

F. Change of State Lab (snow) Somethings change at different tempature

G. Making Cheese Using different Catalysts

H. Middle School Gardens (Tulip Bulbs)

I. Chemistry Independent Project (temperature, salt and boiling, temp and solubility, mixing)

J. Osmosis Egg Lab

What really happens during osmosis

Question #3


 * Using the Scientific Method**

Inspired by the results of our Learning Garden data, we conducted different experiments using kidney beans in the lab. Answer the questions below using the data from the graph below:

Growth of Tulip Plants (cm) at **Haverford** **School** (Suter) || Control (potting Soil) ||
 * || Middle School Garden || Lower School Garden || West Garden
 * || 9 || 8 || 16.5 || 23.5 ||

To record the growth of a kidney bean
 * a) What was the purpose of this experiment (original question)?**


 * b) Write a good hypothesis for this investigation? ( if . . then . . because)?**


 * c) What is the manipulated variable in this experiment?**


 * d) Name THREE variables that are kept constant in this experiment?**


 * e) Where would you get the soil for the control group? Explain why.**

f) Make a Graph for the Data Above.

Question # 4
