  1. Warm-up: Problem Question/ IV and DV Review (Day 2) Read the paragraph below. Be thinking about: problem question, independent and dependent variable. Patty Power Mr. Krabbs has created a new sauce that he thinks will reduce the production of body gas associated with eating krabby patties from the Krusty Krab. He recruits 100 customers with a history of gas problems. He has 50 of them (Group A) eat krabby patties with the new sauce. The other 50 (Group B) eat krabby patties with sauce that looks like the new sauce but is really just a mixture of mayonnaise and food coloring.

  2. Warm-up: Problem Question/ IV and DV Review (Day 2) Answer the following questions in the warm-up section of your lab notebook using complete, detailed sentences. What is the independent variable (IV)? What is the dependent variable (DV)? What was the problem question Mr. Krabbs was investigating?

  3. Warm-up: Hypothesis Review (Day 3) Read the paragraph below. Be thinking about the key components to a well-written hypothesis. Answer the question in your lab notebook. Slimotosis Sponge Bob notices that his pal Gary is suffering from slimotosis, which occurs when the shell develops a nasty slime. His friend Patrick tells him that rubbing seaweed on the shell is the perfect cure. 1. Write one possible hypothesis that Sponge Bob might test in an investigation for Gary’s slimotosis problem. (Remember to use the correct formatting!)

  4. Practice:How to Write a Procedure • Write a 3(+) step procedure for putting safety glasses/goggles on your face. • Remember that this should be a numbered list of detailed statements.

  5. Warm-up: Procedure Review (Day 4) Read the paragraph below. Be thinking about the type of procedure needed for a reliable experiment. 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 it would help plants produce more flowers. He planted two plants of the same size in separate containers with the same amount of potting soil. He placed one plant in a sunny window and watered it every day with fertilized water. He placed the other plant on a shelf in a closet and watered it with plain water every other day.

  6. Warm-up: Procedure Review (Day 4) Answer the following question in your lab notebook (in the warm-up section). Be sure to use complete, detailed sentences in your answer. 1. What did SpongeBob do wrong in this experiment? Explain (using details from the paragraph). Suggest ONE way that he could improve the experiment.

  7. Time vs. Bubbles • Problem Question: How does the amount of time (10, 20, and 30 sec) in a trial affect the number of bubbles blown with a piece of bubble gum? • Hypothesis: (Use “If (IV), then (DV) because” format.) • Data: Create a data table to collect your data. Include title, column for IV, column for DV, multiple trials, column for averages etc. in your data table. • COLLECT YOUR DATA! • Once you have finished collecting your data, you need to GRAPH YOUR DATA (use the average).

  8. Writing a Conclusion: Super BubblesUse the “Writing a Conclusion” guidelines page and the data given on the next slide to begin to write your own conclusion about the Super Bubbles investigation.

  9. Super Bubbles Patrick and SpongeBob love to blow bubbles, so they bought Super Bubble Soap at Sail-Mart. The ads claim that Super Bubble Soap produces bubbles that are twice as big as bubbles made with regular bubble soap. They made up two samples of bubble solution – A: 5 oz. of Super Bubble Soap and 5 oz. water and B: 5 oz. regular soap and 5 oz. water. Using their favorite bubble wands, they blew 10 different bubbles and tried their best to measure the diameter of each one. Bubbles (diameter in cm)
