|Experiment Title:||Hot and Cold|
|What was the purpose of your experiment? Provide a brief description of what you were hoping to learn, discover, or study.:||After reading about olfactory receptors and smells in Ada Twist Scientist, we wanted to learn if hotter things had a stronger smell than colder things.|
|What was your hypothesis?:||Our hypothesis was that a hotter thing (of the same thing) smelled stronger than a colder thing.|
|What materials did you use in your experiment? List them all.:||Hot dogs
|What procedure was followed? Provide a brief description of the steps you followed during your experiment.:||1. We smelled cold hotdogs and noticed how strong the smell was.2. We put hotdogs in the microwave and set the time.
3. We took the hotdogs out.
4. We smelled the hotdogs out and smelled them again, noting the difference in the strength of smell.
|What were the results of your experiment?:||We could smell the hotter hotdogs from the microwave but the colder hotdogs we had to lift to our nose to smell.|
|What is your conclusion after conducting the experiment? Was your hypothesis correct or incorrect? What did you learn?:||We could smell the hotter hotdogs because air and the smell in the air expands when things are hotter and so we think that it carries the smell farther to your nose.|
