Day 3 – Observations


Practicing scientifically sound observations. As this experiment continues, hopefully you will be able to see the impact the environment has on living things and specifically how pH level can impact plant growth.

Big Idea

Observing the effects the environment has on living things.



  • Consistent: something that doesn’t change, no matter what happens in the experiment
  • Dependent variable: the variable being tested by an experiment
  • Hypothesis: an idea that is posed to solve or explain a question that can be tested
  • Independent variable: the variable that is changed in an experiment
  • Inquiry: asking questions to learn something new
  • Medium/Media: the material in which plants grow
  • Nutrients: substances that provide nourishment essential for life
  • Reliable: if you can repeat an experiment and get the same results
  • Validity: the experiment and testing you completed are accurate and measure what you intended to measure.
