Experimental Design Diagram Template      

  1. State your question:   How does Poison Ivy grow and what makes poison Ivy decay?


  1. Research to find quality background information on things already known about the relationship between your chosen variables.  Always be thinking in terms of CLAIM, EVIDENCE, REASONING!


  1. Based on your own background knowledge and your research, make your prediction (What do you think will happen in the experiment.)

    1. If_____I pull the poison ivy weeds out________ Then_____It will grow back________  Because____The roots aren’t fully gone which makes them come back up again_________


  1. Create a data table.  


  1.  List 5 (at least!) controlled variables important for this specific experiment.

Amount of sunlight,  water/moisture, plot surface area,  the start density of poison ivy, all dirt for soil


  1. List the materials needed for the experiment.

  1.  Waterproof rubber gloves

  2. Poison for the poison ivy

  3. Thick plastic garbage bags

  4. Measuring tape

  5. Garbage bags

  6. Shovel



  1. Write out a step-by-step procedure for carrying out the experiment INCLUDING PICTURES/VIDEO!  *Someone should be able to repeat your experiment from your procedure.  

  1. Put on your protective equipment

  2. Find a patch of poison ivy

  3. Stake 3 different areas

  4. Label plots Plot A(control group), Plot B(manual pulling group), Plot C(chemical spray group)

  5. Look at each spot and measure the percentages of poison ivy.

  6. Do the different treatments for each plot

  7. Clean equipment and clothes

  8. Return every few weeks

  9. Log weekly

 In studying my environment I have made many discoveries on my how my plants are affected by their environment. I have been researching poison ivy and how to kill it.  In been studying it I have learned that the poison ivy reacts to poison.  I took a deep analysis on the poison ivy in my area and saw that it was not only on the ground but on huge thick vines climbing trees.   I also noticed a dead tree with the start of the vine still standing.  I am discovering how hazardous poison ivy is how it is spread about everywhere.
