Rigoberto writes down his hypothesis that more salt will dissolve in cold water than in warm water.  He adds salt to different temperatures of water and records his observations including the amount of undissolved salt.  He finds that there is more salt dissolved in warm water than cold water.  What should Rigoberto do next to make sure that his conclusion is valid?

• do another investigation with sugar
• repeat his investigation using a different liquid than water
• repeat his investigation to see if his results are the same
• change his results to match his original hypothesis

Which question would be best to answer using a scientific investigation?  

• Why are people afraid during thunderstorms?
• How easy is it to shovel snow?
• Are some clouds prettier than others?
• Does temperature affect the amount of rain?

A group of people trained to climb a mountain.  As they practices in high altitudes, a researcher measured changes in their lung strength.  Why is it important that her study has a control group?

• O  to ensure that everyone in the group was strong enough to climb a mountain
• to test equipment for measuring lung strength
• to share her research with as many people as possible
• to compare typical lung strength with the effects of training

Austin is studying states of matter by heating water in a pan.  Which statement from his notebook is an observation?

• It is hard to estimate the size of the bubbles.
• Tiny bubbles form on the bottom of the pan.
• The bottom of the pan must be very hot.
• I think there is air in the bubbles.

Amanda makes the following hypothesis:  If the humidity increases, it will help plants grow.  Which of these describes a controlled experiment that would best help Amanda prove or disprove her hypothesis?

• recording the number of tall plants and short plants in different fields that have different humidity levels
• observing plant growth in a greenhouse with a constant humidity and in a greenhouse with changing humidity
• O  measuring the temperatures and humidity in a greenhouse that has both short and tall plants growing in it
• O  making a model to observe whether water collects on the walls of a greenhouse with increasing humidity

What would the INDEPENDENT variable be in an experiment testing which types of paper airplane goes furthest?

• the paper used
• the type of paper airplane
