growing bacteria from yogurt

Postby cio1980 » Sat Mar 17, 2018 7:37 pm

Hi my child is doing her science fair project on if her yougurt really has live culture. I’m confused about the variables and the trials. Any ideas? How does the control works?

Hello and welcome to Science Buddies,
Which project is your child doing? Here are links to 2 of the projects in the Science Buddies project database:

https://www.sciencebuddies.org/science- ... rt#summary

https://www.sciencebuddies.org/science- ... #materials

The controls and the variables will be different depending on the project. Read the different sections in the projects, particularly the introduction, references, and procedures.

Also, you can read about variables and controls in the section titled "Constructing a Hypothesis" in the Science Buddies project guide:

Let us know if this helps and if you have more questions.
