Teacher notes for The Great Fakesperiment Classroom Stations From Science Scope, February 2009
The scenarios should be printed on card stock and placed as stations in the classroom. Additional extension questions could be added. The scenarios were retyped exactly as they appeared in the article.
For Sped/ESL do not use all the stations. Choose the stations that you feel would be the most appropriate. Use basic version as needed.
For Regular use regular version which has students identify the IV, DV, and CV. For bonus have them write a good hypothesis.
Spend one day on this activity and get through as many stations as possible. If you would like to complete all 10 stations, it will take two days.
This should be done as a station lab and not a whole class discussion.
The Great Fakesperiment Classroom Stations Basic version
From Science Scope, February 2009
Station #1
Music may help people relax. Darius got two groups of people together. He took everybodys pulse. Then he allowed one group to listen to soothing music while the other group sat in silence. After the song was over, he measured everyones pulse again.
What is the dependent variable?
sitting in music or silence
pulse
type of music
Darius
Station #2
People say that cars get better gas mileage when their tires are properly inflated. Sayeema wanted to test if this was true, so she filled the gasoline tank in her car, inflated the tires to the car makers suggested pressure, drove her car, and then calculated the miles per gallon. The next time she filled the cars tank with gasoline, she reduced the pressure of air in her tires. Once again she drove the car over the same roads and calculated the miles per gallon. She tried the process again with tires that were inflated a little more than the suggested pressure.
What is the independent variable?
gas mileage
tire inflation pressure
type of gasoline used
roads where the car was driven
Station #3
It has been said that preservatives such as salt help keep food fresh. Imaan made 18 loaves of bread using the same recipe and baking method. In nine of them, she used no salt. In the other nine, she used salt. After the loaves were baked, she placed each of the loaves in a plastic bag and left them close together on the counter in her kitchen. Each day she looked at them to see if any mold had started to grow.
What is the dependent variable?
location of bread on the counter
amount of salt used in the bread
mold growth on the bread in the bags
number of loaves of bread
Station #4
Baking soda is an ingredient in chocolate chip cookies, but not much of it is used in the recipe compared to other ingredients such as flour. James did not think the small amount could be important to the taste of the cookies. He made four batches of cookies using the same recipe. One batch had no baking soda, one had half the amount called for in the recipe, one had the required amount, and one had double the amount. After making the cookies, he had 25 people do a taste test and rate the cookies from delicious to disgusting.
What is the independent variable?
amount of baking soda put into the cookies
number of batches of cookies he baked
cookie taste
amount of flour used in the cookies
Station #5
Emily made four paper helicopters. Each was made out of a different kind of paper. She flew each one several times in the hallway and recorded how long each stayed in the air.
What is the independent variable?
flight time
number of helicopters
type of paper
hallway
Station #6
Ethan filled 10 cups of the same size with equal amounts of water. He divided the cups into five groups of two cups each. The groups were placed in five different locations around his house. After two weeks, he measured the remaining water to determine how much had evaporated, by measuring how much water remained in each cup.
What is the dependent variable?
locations of cups
amount of time they were left in locations
amount of evaporated water
size of cups
Station #7
Whether paint is oil-based or water-based could determine how long it takes to dry. Liliana found two pieces of the same kind of pine wood and painted one with oil-based blue paint and the other with water-based blue paint. Then she timed how long it took for each piece to dry.
What is the dependent variable?
color of paint
oil-based or water-based paint
drying time
kind of wood
Station #8
Caffeine may make people more alert. Devin tested 100 people by using their scores in the same video game. Fifty of the people drank a can of regular Brand X caffeinated soda half an hour before they played the game. The other 50 drank a similar amount of Brand X caffeine-free soda before playing. He recorded each persons score on the game.
What is the independent variable?
amount of caffeine in the soda
video game score
amount of playing time
number of people
Station #9
Richelle made an air-pressure device that could launch potatoes. She added air to the device using her bicycle tire pump. For 10 launches, she used 10 pumps of air. For another 10 launches, she used 20 pumps of air. For the final 10 launches, she used 30 pumps of air. After launching a potato, she carefully measured how far it traveled.
What is the dependent variable?
number of pumps
distance the potato traveled
size of the potato
kind of pump used
Station #10
Malcolm had always heard that plants grow better if you talk to them. He purchased 10 of the same kind of plant, measured the height of each one, and made two groups of plants that he kept in similar conditions. He talked to one group for a half an hour each day but did not talk to the other group. After three weeks, he measured and recorded the height of each plant again.
What is the independent variable?
talking or not talking to the plants
amount of plant growth
number of plant groups
kind of plants
What is the dependent variable?
talking or not talking to the plants
amount of plant growth
number of plant groups
kind of plantsThe Great Fakesperiment Classroom Stations Honors Version
