24. More Science Tools You will be also using tables, charts, and/or graphs to display data from your experiments and investigations. There are several kinds you may already be familiar with. Charts, Tables, and Graphs Tables Data is organized in rows and columns Bar Graphs Data is displayed using horizontal or vertical bars. The bars represent a given data set using a scale. Line Graphs Data is displayed using connected points on a graph. The line represents a given data set using a scale. Circle Graph Data is displayed in a circle divided into sections. Each section represents a part of the whole and allows for a comparison between sections and the whole. Another term for circle graph is pie chart.

25. The Scientific Method Now that we are familiar with the vocabulary and the tools you will be using, you need to know the process it takes to complete a scientific inquiry or experiment. Steps in the Scientific Method 1.Make an Observation 2.Ask a Question and Research 3.Make a Hypothesis 4.Design and Conduct and Experiment 5.Analyze Results & Draw Conclusions 6.Report Results

26. Observation What we see, hear, smell, feel, or taste often lead us to wonder about things. When you want to design an experiment, begin here. Look around. What observations can you make that cause you wonder… My Observation “I saw this weird ice cream called Dippin Dots.”

27. Question “What if…” These two words lead to the beginning of a scientific investigation. These two words lead to the beginning of a scientific investigation. First, observe. “ I saw a kid eating Dippin Dots at the water park. That’s some really strange ice cream! Next, question. “I wonder if it melts slower than ice cream scoops?” Your question should be one that can lead you to make a discovery. It should begin with words such as what, when, where, why, or how. Once you have your question, you need to do some research. If I want to know if Dippin Dots melt slower, I must first learn about Dippin Dots. Using research tools, I would find information and learn about Dippin Dots. This will help me when I begin to design an experiment.

28. Research Dippin Dots From www.dippindots.com www.dippindots.com tiny beads of ice cream, yogurt, sherbet, and flavored ice tiny beads of ice cream, yogurt, sherbet, and flavored ice flash frozen flash frozen can melt if not stored correctly can melt if not stored correctly require sub-zero storage require sub-zero storage would stick together in your home freezer would stick together in your home freezer

29. Hypothesis A hypothesis is an educated guess about what might happen in a scientific investigation. If my questions is: “Will a scoop of Dippin Dots melt slower than a scoop of ice cream? After my research, I could formulate the hypothesis: “Dippin Dots will not melt slower than a scoop of ice cream. Now that you have your hypothesis you can begin to design an experiment to test your hypothesis.

30. Experiment An experiment is a step by step process for testing a hypothesis. Experiment should be repeated several times. We call these trials. These questions will help you design an experiment. What materials will you need? What materials will you need? What are your variables? Variables are the things that stay the same and things that change. What are your variables? Variables are the things that stay the same and things that change. How will you measure and record your data? How will you measure and record your data? What will my data table or chart look like? What will my data table or chart look like? As a class, think of possible answers to these questions.

31. Experiment Let’s design an experiment together. Create a materials list. Determine your variables. Write step by step directions on how you will conduct your experiment. Design a data table to record your observations or measurements.

32. Our Experiment Let’s begin with the materials list. The materials are everything your will use to conduct the experiment. What will we need for our experiment? Dippin Dots, ice cream, measuring spoons, containers, timer, lamp, graduated cylinders Can you think of anything else?

33. Our Experiment Now, what are our variables? A variable is any object, event, or category you are trying to measure. There are two kinds of variables: independent and dependent. There can be more than one. Independent Variable: It is NOT changed. It is constant. Dependent Variable: Changes depending on other factors What do you think our variables will be for our experiment? Independent: containers, amount, time Dependent: Dippin Dots, ice cream

34. Our Experiment What are we going to measure? In this experiment, we are going to measure the amount of liquid there is after a specific amount of time for each trial. Experiments need to be repeated at least 3 times; each time is called a trial. Let’s design a table to record our data. A table arranged information in rows and columns.

35. Our Experiment Our table can look like this. Which Ice Cream Melts Faster? Dippin Dots LiquidIce Cream Liquid Trial 1 Trial 2 Trial 3

36. Our Experiment Here is an example of step by step directions for this experiment. Step 1: Measure out an equal amount of Dippin Dots and ice cream and place each into a container. Step 2: Place each container under the lamp so each one receives the same amount of light. Step 3: Set the timer for 5 minutes. Step 4: Pour the melted ice cream/ Dippin Dots liquid into separate graduated cylinders and record the amount on the data table. Step 5: Clean your materials and then repeat the experiment at least two more times.

37. Data Documents your times, measured amounts, etc. as you conduct the experiment and write the information down on your chart or table. Describe what you see, hear, smell, feel, or taste- if that is part of the experiment- with your data. Observations

38. Our Experiment After you complete all of your trials, look at your data and analyze the similarities, differences, and other observations. *the following data table is NOT from an actual experiment. It was designed for instructional purposes only. In all three trials, there was more melted liquid in the ice cream container than in the Dippin Dots container. The ice cream appeared to melt faster than the Dippin Dots. Which Ice Cream Melts Faster? Dippin DotsIce Cream Trial 13mL5mL Trial 24 mL5mL Trial 32 mL6 mL

39. Results & Conclusion Conclusions begin with analyzing the results of your experiment by taking a close look at the data you collected. What did you notice about the data in each trial? How did it changed, if there were any changes? In the conclusion, use the results and the data to write about whether or not the experiment supported your hypothesis. Write about factors the effected your experiment and how you would change them if you did it again.

40. Report When scientists have finished conducting their experiments, analyzing the results, and writing their conclusions, they publish their results. Examples of published results are: scientific journals scientific journals posters at school posters at school display boards in a science fair display boards in a science fair
