SpongeBob loves to garden and wants to grow lots of pink flowers for his pal Sandy. He bought a special Flower Power fertilizer to see if it will help plants produce more flowers. He plants two plants of the same size in separate containers with the same amount of potting soil. He places one plant in a sunny window and waters it every day with fertilized water. He places the other plant on a shelf in a closet and waters it with plain water every other day. At the end of two weeks, he counts the number of flowers on each plant. What did SpongeBob do wrong in this experiment?
had too many IVs
had only one IV
had too many DVs
had bad IVs

What should he have done to test the Flower Power fertilizer?
only have changed the amount of sunlight each plant gets
only have changed how often each plant gets water
only changed the location of the plants
only changed the type of fertilizer
Joanna read that certain perfumes would cause bees to leave the hive and act in an agitated fashion. She decided to investigate the response of bees to five different perfumes- Ralph Lauren, Armani, Marc Jacobs, Vera Wang, and the last is an odorless liquid. She placed a saucer containing 20 ml of perfume A 10 meters from a beehive. She then recorded the total number of bees that emerged from the hive during a 15 minute interval and made observations on their behavior. Using a 30 minute interval between tests to allow recovery time for the bees, she then repeated the procedure to test the remaining three samples. Each test was conducted on the same day with similar weather conditions. What was the IV?
the bees’ agitation
the bees
perfume
thirty minutes

Each test was conducted on the same day with similar weather conditions. List three constants.
same beehive, time, amount of perfume
same perfume, no repeating the procedure, odorless liquid
didn’t have a control group, the different perfumes, odorless liquid
response of bees, reaction of the bees, same perfume

Alex wonders if adding salt to water will affect how long it takes the water to freeze. Alex thinks that salt water will freeze more quickly than fresh water. He decides to check his hypothesis by conducting an experiment. Alex takes two ice trays and fills one with distilled water and the other with distilled water that has two tablespoons of salt added. He makes sure he puts exactly the same amount of water in each ice tray. Alex takes the trays and puts them side by side in the freezer. Alex checks the ice trays every 10 minutes to see if the water in each tray has begun to freeze. Alex finds that after 20 minutes the water in the ice tray without the salt has started to form ice, while the ice tray with the salt water is still completely liquid. What should Alex’s hypotheses be?
if Alex uses salt, then the water will freeze faster
if Alex uses water, the salt will freeze faster
when Alex uses salt, the water will freeze faster
if Alex uses salt, the salt will freeze faster
