| Stavka koja se može prevući | arrow_right_alt | Odgovarajuća stavka |
|---|---|---|
Constants | arrow_right_alt | gathering data |
Observation | arrow_right_alt | logical conclusions about observations |

In the video, the Amoeba Sisters talked about removing barnacles from boats. Identify the variables in their experiment:
| Stavka koja se može prevući | arrow_right_alt | Odgovarajuća stavka |
|---|---|---|
Dependent Variable | arrow_right_alt | Anti-Barnacle Additive concentrations |
Controlled Variables/Constants | arrow_right_alt | number of barnacles |
Independent Variable | arrow_right_alt | boat model, boat size, environment, time |
Every good experiment has variations to their experiment. In this video, the Amoeba Sisters varied the amount of Anti-Barnacle Additive. Which 3 were included in their percentages?
Which two variables go on a graph?
Which of the following are considered ethical Science "no-nos"?
Pinky’s science fair project in junior high focused on an observation that the crickets outside her window chirped less frequently when the temperature was colder.
Consider if data was collected consisting of the average number of cricket chirps at different temperatures in her backyard.
Match the following:

|---|---|---|
Dependent Variable | arrow_right_alt | different temperatures |
Independent Variable | arrow_right_alt | average number of cricket chirps |
