Research Plan:


My independent variable is the temperature and the environment. My Dependent variable is the speed of the germination. My research question is, I wanted to investigate how different temperatures of the environment, one normal, hot, and cold can affect the speed of a pea plant germination. According to Home Guide, Factors Necessary for the Germination of Pea Seeds ,” Peas are considered a cool-weather crop, as they germinate best at temperatures that range from 45 to 65 degrees” (Home Guide). The pea plant will be able to germinate in colder temps because pea plants are usually germinated and planted in very early spring and are frost tolerant. 

Controlled Variables: 

Controlled variables

Why it needs to be controlled

How to control the variable 

The temp of the environment  

Because it is the independent variable and it is being tested on that

Use the same temp and environment for each three peas. 

The stage of peas

Can’t have peas at different stages of germination 

Use thirty same peas (seeds)

The paper towel 

Can’t have different sizes and types of paper towel 

Use same paper towel  

The water

Can’t have extra chemicals in water 

Use tape water 

The person doing experiment 

It can change if a different person is doing it 

Same person (me) 

The place for each plant

Needs to be in the same place of environment

Same place of environment 

The thermometer and use in fahrenheit

Because celsius and fahrenheit are different and to keep it to one 

Use same thermometer and fahrenheit

The time of the day the pea is measured 

Because then it can be measured equally 

Measure the pea everyday


  • Pea plant seeds (30)
  • Small ziplock bags (3)  
  • Cold environment (50 F) 
  • Normal environment (70 F)  
  • Warm environment (80 F) 
  • Three thermometer’s
  • 105 ml of tape water
  • Three bounty paper towels each same size (L 11 in. - W 6 in.) 
  • Sharpie
  • Extra paper towel 
  • Graduated cylinder



      1. Collect materials in the materials list above.

      2. Find and measure the temperature with the thermometer, how warm/cold the environments the peas are goin to be in. 

      3. Do one trial for each room and let the thermometer sit in the environment for 5 mins. 

4.  Place a sheet of paper towel in a ziplock bag fold vertically 2 times if needed.  

5.  Repeat step 4 two more times.

6.  Place 10 peas equally spaced out half an inch in a ziplock bag in the center of the paper towel and then fold the paper and then pour gently in the zip lock bag, on the paper towel, 35 ml of tap water with the graduated cylinder, in each zip lock bag then seal tightly closed. 

7.   Repeat step 6 for the other 20 peas then write with a sharpie on the zip lock bag the environment and temp it is in. 

8.   Then gently place each zip lock bag in each environment in a specific place to get equal temp. 

9.    Every day at a specific time (7:30 ) record how much the pea grew and if a root is growing and if for how long. 

10.    Repeat step 9 for each pea repeat for 7 days or until the pea completely sprouts and there is a root growing. Take pictures everyday of the peas in each environment.

                  11. Record all data in the charts. 




Questions and Answers

1. What was the major objective of your project and what was your plan to achieve it? 

My main objective for my project was to answer my reserach question, how does the temperature of an enviroment effect the pea plants germination process. I wanted to find out what temperature would be the best for pea seeds to germinate fastest because I like planting and sometimes my plants fail to germinate and sprout succesfully. I wanted to achieve my hypothesis, which I stated that the peas in the cold temperature would germinate faster. My hypothesis was wrong because, in the end the peas in the warm temperature germinated faster than the peas in the cold temperature. 

       a. Was that goal the result of any specific situation, experience, or problem you encountered?  

My goal did come in a result of me knowing more about pea plants, and how they need moisture to germinate, which is good knowledge for the next time I will be planting. 

       b. Were you trying to solve a problem, answer a question, or test a hypothesis?

I was trying to solve my research question, how does the temperature of an enviroment effect the pea plants germination process. I learned a lot from this experience not from just the pea plants but how to manage my time and to be really specific when it comes to science experiments. 

2. What were the major tasks you had to perform in order to complete your project?

The major tasks I had to preform in my project was finding a science fair topic, creating my procedure, and collecting and observing data. It was important to first find a science topic, not too difficult, but durable and that could be done. It took me a lot of time to find a science topic for my science fair project. I did not exept how much time it would take me to brainstorm, to find a topic for my science fair project. after I had found my topic, I had to create a procedure. It was hard going over and over my procedure making sure it was detailed enough to be followed by soemone else. I had to calculate many things, like the amount of water, materials, or even what could go wrong, like water spiIling and to be prepared for that. Once I had done my procedur and was actually doing my science experiment, I had to collect data everyday and observe. I had to stay on track and record every little piece of data, because if I didn't record anything for my science experiment, I would have no evidence. 

       a. For teams, describe what each member worked on.

3. What is new or novel about your project?

What is new about my project, is the fact that I was comaping different temperatures with peas. 

       a. Is there some aspect of your project's objective, or how you achieved it that you haven't done before?

No, there is no aspect of my projects objective or how I achieved it that I had'nt done before. 

       b. Is your project's objective, or the way you implemented it, different from anything you have seen?

No, it has not had been fifferent from anything I have seen. 

       c. If you believe your work to be unique in some way, what research have you done to confirm that it is?

My work is unique because this helps me find out the question, how does the temperature of an enviroment effect the pea plants germination process. 

4. What was the most challenging part of completing your project?

The most challenging part of my project was finding a science fair topic, and writing out my procedure and dependent variable. It took me a long time to find a way to measure my data. It also took a few tries to get as specific as possible for my procedure. I had to put a lot of throught and productive struggle into my procedure and dependent variable because I needed it to be as specific as possible. It also took me a long time to brainstorm a topic to start off with I would like. 

      a. What problems did you encounter, and how did you overcome them?

Problems I had to encounter was creating my procedure and finding a dependent variable, a way of measuring my data. It was hard to create the procedure, and I had to keep on making it more specific as much as possible. I overcame those problems by thinking about everything that would happen in the procedure and I had to thik of all the thiks that could also go wrong, like water spilling or an uneven ripped paper towel. 

      b. What did you learn from overcoming these problems?

I learned that I need a lot of time to productivly brainstorm about my project, like the procedure. I learned that I need to plan out time to do all of these things, and that brainstorming does'nt take 5 mins. It takes more than that. 

5. If you were going to do this project again, are there any things you would you do differently the next time?

I would definitely plan time to fill out the questions before doing the experiment. I would have managed my time better at the begin ing of my whole science experiment. 

6. Did working on this project give you many ideas for other projects? 

This project did give me new ideas and questions I had with no anwers. If I where doing more experiemnts in the futur than I would definitly do it related to plants. First you can test and find answers on living things but don't use a animal or human, and second there are still so many questions I have out there about the science of plants. 

7. How did COVID-19 affect the completion of your project?

COVID-19 did not affect the completion of my project because it was on plants at home which I could controll all those variables.
