I NEED HELP PLS I’LL GIVE BRAINLIEST Scenario 1: Two scientists wanted to determine il temperature affects the growth rate of plants. They each prepared an experiment.
Scientist 1
Take four plants and pot them in styrofoam coffee cups. Give them each the same amount of
soil. Put one plant in a room at 68 degrees Fahrenheit, put the second in the basement where it
is colder, put the third outside on a cloudy day, and put the fourth outside on a sunny day Make
sure to water the plants every day. See which plant grows better
Scientist 2
Take four 5 cm bean plants Plant each plant in a 3 inch clay pot. Plant each one with 5 cm deep
soil Use potting soil for all plants. Put the first plant in a room with a temperature of 50 degrees
Fahrenheit. Put the second plant in a room with a temperature of 60 degrees Fahrenheit Put
the third plant in a room with a temperature of 65 degrees Fahrenheit. Put the fourth plant in a
room with a temperature of 70 degrees Fahrenheit Make sure each room has a humidity level
of 60% Give all of the plants 12 hours of light per day with a 40 watt light bulb, 30 cm above the
pots Water each plant with 20 mL of tap water at noon each day Measure the height of each
plant with a metric ruler every two days. Record data for two weeks
1. What is the independent variable?
2. What is the dependent variable?
3. What are the control variables?
4. Which scientist prepared a better experiment? Why?
5. What if anything, is wrong with the other scientist's experiment?
