Scientific Inquiry with SpongeBob Name: Part 1

SpongeBob and his Bikini Bottom pals have been busy doing a little research. Read the description for each experiment and answer the questions.

1 - Patty Power

Mr. Krabs wants to make Bikini Bottoms a nicer place to live. He has created a new sauce that he thinks will reduce the production of body gas associated with eating crabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat crabby patties with the new sauce. The other 50 (Group B) eat crabby patties with sauce that looks just like new sauce but is really just mixture of mayonnaise and food coloring. Both groups were told that they were getting the sauce that would reduce gas production. Two hours after eating the crabby patties, 30 customers in group A reported having fewer gas problems and 8 customers in group B reported having fewer gas problems.

A) Which people are in the control group? GROUP B IS THE CONTROL GROUP BECAUSE THEY RECEIVED NO “SPECIAL” SAUCE BUT WERE STILL GIVEN A SAUCE TO TEST MR. KRAB’S HYPOTHESIS.

B) What is the independent variable? THE INDEPENDENT (MANIPULATED) VARIABLE IS THE TYPE OF SAUCE (“SPECIAL” SAUCE AND FAKE SAUCE).

C) What is the dependent variable? THE DEPENDENT (RESPONDING) VARIABLE IS THE AMOUNT OF GAS EXPERIENCED BY THE CUSTOMERS.

D) What should Mr. Krabs’ conclusion be? BASED ON 30 OUT OF 50 (60%) CUSTOMERS FEELING LESS GAS IN THE “SPECIAL” SAUCE GROUP (A), MR. KRAB’S COULD CONCLUDE THE NEW SAUCE WORKS.

E) Why do you think 8 people in group B reported feeling better? THE EIGHT PEOPLE FROM GROUP B THAT DID NOT RECEIVE THE NEW “SPECIAL” SAUCE MAY HAVE BEEN EXPERIENCING THE PLACEBO EFFECT, WHICH OCCURS WHEN SOMEONE BELIEVES TO BE “CURED” THOUGH THEY DID NOT RECEIVE AN ACTUAL “TREATMENT” FOR AN AILMENT.

2 – Slimotosis

Sponge Bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell develops a nasty slime and gives off a horrible odor. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure, while Sandy says that drinking Dr. Kelp will be a better cure. Sponge Bob decides to test this cure by rubbing Gary with seaweed for 1 week and having him drink Dr. Kelp. After a week of treatment, the slime is gone and Gary’s shell smells better.

A) What was the initial observation? THE INTIAL OBSERVATION IS THAT GARY HAS SLIMOTOSIS.

B) What is the independent variable? THE INDEPENDENT (MANIPULATED) VARIABLE IS THE TYPE OF TREATMENT (SEAWEED AND DR. KELP)

C) What is the dependent variable? THE DEPENDENT (RESPONDING) VARIABLE IS WHETHER OR NOT THERE IS STILL SLIMOTOSIS ON GARY’S SHELL.

D) What should Sponge Bob’s conclusion be? WHILE THE SLIMOTOSIS IS GONE, THERE IS NO WAY TO TELL IF IT WAS THE SEAWEED OR THE DR.KELP THAT CAUSED THE SLIMOTOSIS TO GO AWAY.

Scientific Inquiry with SpongeBob Name: 3 – Marshmallow Muscles

Larry was told that a certain muscle cream was the newest best thing on the market and claims to double a person’s muscle power when used as part of a muscle-building workout. Interested in this product, he buys the special muscle cream and recruits Patrick and SpongeBob to help him with an experiment. Larry develops a special marshmallow weight-lifting program for Patrick and SpongeBob. He meets with them once every day for a period of 2 weeks and keeps track of their results. Before each session Patrick’s arms and back are lathered in the muscle cream, while Sponge Bob’s arms and back are lathered with the regular lotion.

A) Which person is in the control group? SPONGEBOB IS THE CONTROL GROUP BECAUSE HE DID NOT RECEIVE THE MUSCLE CREAM.

B) What is the independent variable? THE INDEPENDENT (MANIPULATED) VARIABLE IS THE TYPE OF CREAM (MUSCLE CREAM AND LOTION).

C) What is the dependent variable? THE DEPENDENT (RESPONDING) VARIABLE NUMBER OF MARSHMALLOWS LIFTED.

D) What should Larry’s conclusion be? LARRY SHOULD CONCLUDE THAT THE MUSCLE CREAM DOES NOT WORK AS ADVERTISED BECAUSE BOTH PATRICK AND SPONGEBOB SHOWED IMPROVEMENTS AND PATRICK’S MUSCLES DID NOT DOUBLE

4 – Microwave Miracle

Patrick believes that fish that eat food exposed to microwaves will become smarter and would be able to swim through a maze fas te r. He dec ides to per fo rm an

experiment by placing fish food in a microwave for 20 seconds. He has the fish swim through a maze and records the time it takes for each one to make it to the end. He

feeds the special food to 10 fish and gives regular food to 10 others. After 1 week, he has the fish swim through the maze again and records the times for each.

A) What was Patrick’s hypothesis? PATRICK’S HYPOTHESIS IS THAT IF HE MICROWAVES THE FISH FOOD THEN THE FISH WILL BE ABLE TO SWIM THROUGH A MAZE FASTER BECAUSE MICROWAVES MAKE YOU SMARTER.

B) Which fish are in the control group? THE FISH RECEIVING THE REGULAR FOOD ARE THE CONTROL GROUP.

C) What is the manipulated (independent) variable? THE MANIPULATED (INDEPENDENT) VARIABLE IS THE TYPE OF FOOD (MICROWAVE FOOD AND REGULAR FOOD).

D) What is the responding (dependent) variable? THE RESPONDING (DEPENDENT) VARIABLE IS THE TIME TO COMPLETE THE MAZE.

Scientific Inquiry with SpongeBob Name: E) Look at the results in the charts. What should Patrick’s conclusion be?

PATRICK SHOULD CONCLUDED THAT MICROWAVING FOOD DOES NOT AFFECT INTELLIGENCE. AS EVIDENCE, THE AVERAGE TIMES FOR EACH GROUP COULD BE CALCULATED AND THE MICROWAVED FOOD GROUP DECREASED BY 9.625 SECONDS ON AVERAGE, WHILE THE CONTROL GROUP ONLY DECREASED BY 6.625 SECONDS.

Part 2 - The Bikini Bottom gang loves science class and wanted to do a little research. Read the description for each experiment and use your knowledge of the scientific method to answer the questions. 1 - Flower Power 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 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.

A) What did SpongeBob do wrong in this experiment? Explain.

UNFORTUNATELY, SPONGEBOB TESTED MORE THAN ONE MANIPULATED VARIABLE: LOCATION OF PLANT (SUNNY WINDOW AND CLOSET), FREQUENCY OF WATERING (EVERY DAY AND EVERY OTHER DAY), AND TYPE OF WATER (FERTILIZER WATER AND PLAIN WATER).

B) What should SpongeBob do to test the effectiveness of Flower Power fertilizer? Explain. IF SPONGEBOB KEPT EVERYTHING THE SAME ABOUT THE PLANTS (NUMBER OF PLANTS, SOIL TYPE, LOCATION, AND FREQUENCY OF WATERING) AND ONLY TEST THE TYPE OF WATER.

2 - Super Snails Gary is not the smartest snail in Bikini Bottom and believes he can improve his brain power by eating Super Snail Snacks. In order to test this hypothesis, he recruits SpongeBob and several snail friends to help him with the experiment. The snails ate one snack with each meal every day for three weeks. SpongeBob created a test and gave it to the snails before they started eating the snacks as well as after three weeks.

A) Based on the data provided, do the Super Snail Snacks work? Explain your answer.

W H I L E I T S E E M S G A R Y A N D B A R R Y M A D E IMPROVEMENTS, SINCE THERE WAS NO CONTROL GROUP AND NO SPECIFIC DETAILS AS TO WHAT SPONGEBOB’S TEST FOR THEM WAS, FURTHER TESTING WOULD PROBABLY BE NEEDED TO DETERMINE THE EFFECTIVENESS OF THE SUPER SNAIL SNACKS.

Scientific Inquiry with SpongeBob Name: 3 - Bubble Time

Patrick loves bubble gum and would like to be able to blow bigger bubbles than anyone else in Bikini Bottom. To prepare for the Bikini Bottom Big Bubble Contest, he bought five different brands of bubble gum and needs your help to find the brand that creates the biggest bubbles.

In the space provided write the experiment procedures needed to test the bubble power of the bubble gum brands and help Patrick win the contest.
