VI. DATA COLLECTIONS/OBSERVATIONS: Record all the information you collect and all the observations you make. There is always some kind of data to write down during and experiment. This could be time, temperatures, quantities, good and bad things that might have happened. Remember if possible, data should be in a graph or chart. Sometimes data tables will be provided for you.
VII. CONCLUSION/DISCUSSION/QUESTIONS: This is where you explain your results and describe what you think your data means or proves. Use your data and observations to make inferences.
Design your own experiment 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 three different brands of bubble gum and needs your help to find the brand that creates the biggest bubble. Write an experiment to test the bubble power of the bubble gum brands and help Patrick win the contest.

Roll/sub review Fast 5/vocabulary Number a page in your notebook 1-10 answer the following with either “Quantitative” (QT) or “Qualitative”(QL) Review your test…Polisher’s & Keepers Testing your “Bubble Time” lab. Lets Review what to do Don’t forget you need to report your findings. Submit your lab write-up on Canvas using the template* EXIT TICKET: CONTENT OBJECTIVE: SWBAT apply their Bubble Time Experiment design to test different kinds of bubble gum. LANGUAGE OBJECTIVE: I will be able to organize the results of my Bubble Time Lab to communicate my results.
Vocabulary Words quantitative:.relating to, measuring Scientists are gathering quantitative information about human intelligence. qualitative: describing the quality of something in size, appearance, value, etc. Our difference with animals is a qualitative one.
QT quantitative OR QL qualitative The candle is cylindrical in shape. It is about 2 centimeters in diameter. The candle is translucent. It is a solid. The wick is made of 25 strands of string braided together. The flame begins about 1cm above the top of the candle. The last 2mm of the wick glows red. The burning candle makes no sound. Heat is emitted by the flame. The top of the burning candle becomes wet with colorless liquid.
KEEPERS Know Safety Rules Know basic steps to scientific process Graphing skills……SWEET SOME nice handwriting SOME neat work
POLISHERS • Use scientific language • Process • Way • Method • KNOW lab equipment • Not a sucky up thingy!!!!! • Measuring tube?????? • SPELING • You WILL spell key words correctly. • When writing a sentence, use capitals and periods. • It is when……. What is when?????? • 5.Read what the question is asking you. • Accept or Reject
Writing about variables The not so good! Some you have control over some you don’t. They have different reason’s and a lot more ways to explain them. You should only have one in an experiment.
Writing about variables The much betters! A variable is something that can be changed. The smartest thing to do is to test one variable at a time. A variable is something you can change during an experiment. It can be something you can control or something you can’t control during an experiment. You should only change one variable at a time.
Design your own experiment Example 1 You and friends are having a debate about how chewing different brands of bubble gum affects the diameter of the bubble blown. You need to design an experiment using the steps of the scientific method (problem statement, hypothesis, materials experiment/procedure, observations, and conclusion). In the experiment section, make certain that your procedure is numbered in steps and you include the materials list.
Lab Write-Up Format TITLE: Bubble Time II. PURPOSE: Do different brands of gum affect the diameter of a bubble that has been blown? HYPOTHESIS: If you chew the piece of gum that weighs the most, then the diameter of the bubbles you blow will be larger. IV. MATERIALS: gum “A” Ruler gum “B” Pencil gum “C” One participant to chew gum Example 1
V. PROCEDURE Example 1 1. Tear off a piece of gum A (Bubble Yum) , Orbit gum (B), and Big Red (C) so that each piece is the same size. Repeat this until you have 3 pieces of each brand of gum. 2. Make a data table to hold the data collected during the experiment. It should have four rows and five columns. Label the first row with “Trial 1”, “Trial 2”, and “Trial 3” in the second to fourth columns and “Average Diameter” in the fifth column. In the first column, label rows 2 through 4 with the brand names of the bubble gum. 3. Have the participant chew the first piece of the Bubble Yum for one minute and then blow a bubble with the gum. Measure the diameter of the bubble before it pops with the ruler and record this number in the “Trial 1” column for Bubble Yum. 4. Have the participant chew the second piece of Bubble Yum for one minute and then blow a bubble with the gum. Measure the diameter of the bubble before it pops with the ruler and record this number in the “Trial 2” column for Bubble Yum. 5. Have the participant chew the third piece of Bubble Yum for one minute and then blow a bubble with the gum. Measure the diameter of the bubble before it pops with the ruler and record this number in the “Trial 3” column for Bubble Yum. 6. Average the diameters for trials 1 through 3 and record this number in the “Average Diameter” column for Bubble Yum. 7. Repeat steps 3 through 6 for Orbit gum and Big Red gum.
Experiment Group: participant chewing the gum Independent Variable: the brands of gum Dependent Variable: average size of diameter of bubbles blown Observations/Data Collection: In this step you would record any observations from the experiment that you could actually see. Was the participant tiring or struggling to blow the bubbles? Were the sizes of the piece of bubble gum the same? Anything that you could actually see during the experiment would be an observation. Conclusions: In this step you would analyze and draw conclusions from your data. This is where you might make inferences about the data and how it relates back to your hypothesis. Did your results support your hypothesis or reject it? How could you improve upon this experiment? What would have made this a more credible experiment? A B C
Example 2 The purpose of this lab is to use the Scientific Method to solve a problem. A) Observe and ask questions that lead to a problemB) Form a hypothesis C) Test the hypothesis with a controlled experiment my making observations and gathering data.D) Analyze gathered dataE) Reject or Accept your hypothesisF) Form a conclusion2. Materials2 small pieces of wax paper1 meter long piece of string1 meter stick2 different pieces of bubble gun labeled A and B3. READ directions carefully before starting the lab. 1. Each group will need one piece of gum labeled A and one labeled B. 2.Make 3 observations about each brand of gum.
Example 2 ObservationsGum A Gum B1.____________________________ 1.__________________________2.____________________________ 2.___________________________3.____________________________ 3.___________________________Problem: Which piece of bubble gum blows the biggest bubble?Hypothesis: Predict which piece of gum will blow the biggest bubble and why.______________________________________________________________________________________________________________________________
Procedure:1. The person with brand A will chew their piece of gum for 3 minutes. The person with brand B does not begin chewing until all the tests on brand A are completed. 2. Blow a bubble.3. Using a string, your partner will measure the diameter (distance across) the bubble. Put the string on the meter stick to measure the distance in centimeters (cm).4. Record the measurement in a data table. Repeat the process for trials 2 and 3.5. Find the average bubble size for brand A (add all the distances up and divide by 3) and put in the data chart.6. Repeat steps 1-5 with brand B gum. Example 2
Example 2 Data Table: Design a data collection table to fit the data you will be investigating Conclusion: What brand of gum is the best at blowing bubbles and why? Support your answer with observations and your data.
