Dr. Mia has announced that he has found a better way to produce clean drinking water from the ocean. He claims that his method produces cleaner drinking water in half the time as older methods. What should older scientists do now that Dr. Mia has made this announcement?

• Stop all other research on this topic

• Ask Dr. Mia to produce evidence that supports this claim

• Sell products used in Dr. Mia’s claim

• Update all the existing research to match Dr. Mia’s findings

Amelia and Sophia created identical experiments for their STEM Fair Projects. They both collected data about weather from 2 different weather stations located in the same place behind the school. The only difference was that one weather station had a digital thermometer and the other had a traditional thermometer. Which statement below most likely describes the results they received?

• Exactly the same results because they did the same experiment.

• Exactly the same results because the location of the weather stations was the same

• Completely different results because they are different students with different abilities

• Slightly different results based on the ability to read a traditional thermometer

When scientists design experiments what’s the first thing they do?

• Ask questions and make predictions

• Create a graph and report results

• Collect data

• Draw a conclusion and report the results

When designing an experiment, the scientific question asked must be testable. Which of the following is NOT a scientific question?

• What causes rain to fall from the sky?

• How does heat affect plant growth?

• Why do people see color?

• What is the most popular soda brand?

Tommy is developing an experiment to see whether real sugar or Splenda (an artificial sweetener) will attract the greatest number of ants. Which statement best describes why Tommy should write down his step by step directions in his experimental design?

• So the exact experiment can be repeated by others and the results can be compared

• So the experiment can be changed by others to get different results

• The data will help people decide what type of sweetener to use

• The data will show people which type of ants are the most common
