Humidity Investigation 1

Set up your first investigation using the following procedure: 

  1. Open plastic box and put in humidity and temperature sensor. Note what units both variables are being measured in.

  2. Close plastic box.

  3. Take grow light and clip it on edge of table.

  4. Position it so the light is approximately 10 cm above the box and the light is centered on the box (do not turn on the light).

  5. Prepare a stopwatch or timer for you to count up.

  6. Set up your data table below, so you will be able to record temperature and humidity data, you will take the measurement before turning on the light, and then every minute for 10 minutes.

  7. When you are ready, turn on the grow light and begin timing.

Questions

Please answer the questions below.

In our investigation, we are examining 2 different variables, temperature and humidity. In setting up a table for the results, we want to organize it a specific way. In nearly all scientific tables, you will find the independent variable (IV) on the left and the dependent variable(s) (DV) on the right. 

Determine which variable is being manipulated in this experiment (IV) and which one is responding (DV). List them below.
