6th grade students design an investigation to explore the effect of different soil types on plant growth. They set up three identical pots with different types of soil: sandy soil, loamy soil, and clay soil. Each pot contains the same type and amount of plant seeds. The students measure the height of the plants weekly for a month. This experiment primarily demonstrates which aspect of understanding inquiry?

• The importance of asking questions and defining problems.

• The ability to plan and conduct investigations.

• The interpretation and analysis of data.

• The communication and collaboration of scientific findings.

Before starting an investigation or lab procedure, you should

• try an experiment on your own

• open all containers and packages

• read all directions and make sure you understand them

• handle all the equipment to become familiar with it

Which type of investigation does not have a hypothesis? (a)  

• Descriptive

• Comparative

• Experimental

Select all that apply: Important experiment variables

• Independent variable

• Dependent variable

• Controlled/Constant variables

• None of these variables are important

An independent variable is...

• what the scientist changes at the beginning of each trial

• what the scientist measures at the end of each trial

• all the things that stay the same in every trial

• tools that are needed to conduct the experiment
