Experiment 1: Design an Experiment
I have already performed the experiment and filled in part of the paperwork with photos from my lab experiment. I just need someone to answer the last few questions, as I don’t have the time. I will attach what I’ve already done, just answer the unanswered questions based off of the photos provided, please.
Experiment 1: Design an Experiment
1) List 10 variables that may affect seed germination (5 points)
Temperature | Towel Size* |
Towel Moisture* | Outdoor/Indoor |
Animal Interaction | Human Error |
Sunlight* | Laying Down vs Hanging |
Type of Towel |
2) Which 3 variables did you test? (3 points)
Sunlight, Towel Moisture, Towel Size
3) Write out your hypothesis for each of your 3 variables. (3 points)
4) List your independent and dependent variables as well as your control. (3 points)
Independent:
Dependent:
Control:
5) Insert a picture showing your 3 variables at the end of testing. Your name and date must be handwritten on a piece of paper in the photo. (5 points)
6) Insert a table for your data that includes a title, units and any other useful information. (5 points)
7) Insert an appropriate style of graph that includes a title, units and any other useful information. (5 points)
8) Write a short, concise summary (Conclusion) of what you have learned from you experiment. Did you accept or reject your hypothesis? (5 points)

Experiment 1: Neutralization of Acids and Bases
1) Insert a photo of your litmus results. The picture needs to include your name and date handwritten on a piece of paper in the photo. (5 points)
Table 2: Initial Litmus Test Results (5 points) | |||
Container | Chemical Contents | Litmus Results | Additional Observations |
A | 5 mL Water | Base | Litmus paper is purple |
B | .5g Sodium Bicarbonate, 5 mL Water | Base | Litmus paper is blue |
C | 5 mL Acetic Acid | Acid | Litmus paper is pink |
Table 3: Neutralization (6 points) | |||
Amount of Acid | Litmus Result | ||
1 mL | Still very pink | ||
2 mL | Slightly darker pink | ||
3 mL | Almost a reddish color | ||
4 mL | Purple | ||
5 mL | Blue |
