Research Tips
Do earthworms stimulate plant growth? 
Subject search (Thesaurus): suggests broader, narrower terms and related terms. Terms used by the database.
“earthworms” + “plant growth”. Connect the terms with an "and" to find articles where both are mentioned.
Keyword search (Advanced mode): searches for your terms and suggests more terms to narrow your search down.

“earthworms” + “plant growth”
or use autofill 
“earthworms effect on plants”  
Example of narrowing a broad topic:

"effect on non-native plants"

Possible RES Projects  

1. Build two or more identical miniature land or water ecosystems in a large covered jar or aquarium (edible plants, soil, small herbivores, pond water, air, source of light) and then alter one factor in the ecosystem while keeping all other factors constant to see what changes occur.  

  1. 2. Study the behavior (response to a stimulus of some sort – temperature, light, food, etc.) of small, easily managed animals like aquarium fish, hermit crabs, isopods, or annelids.  

  1. 3. Study the population ecology of those same small, easily managed animals placing different densities in habitats and observing their behavior, aspects of their health, etc. 

  1. 4. Study the growth of plants to various environmental factors (light, soil pH, etc.) 

  1. 5. Test the presence of heavy metals such as lead in water of various environmental sources (lake, link river, parking lot puddles, etc.) 

  1. 6. Test the pH of soil in different environments (burned versus unburned; cultivated versus wild area, etc.) 

 
Group exercise

Groups search for their topics using Thesaurus vs. Advanced Search.  

  • What worked? What didn’t?  

  • How many results did you get? 

  • Were your results relevant? 

  • Which limiters did you use? 

  • Was your term(s) present in Thesaurus? Was it a different term? 

  • What would you do differently next time?  

Evaluating Results 
Consider the following points when reading a scholarly article: 
1. Know your research question or argument.
2.
You don't have to read the entire article in order.
3. Read critically.
4.
Read the reference section. 
5. Take notes.
