Preparing for Scientific Inquiry Work Sample Part II
Day 5 Breaking Down SI: Forming the Question/Hypothesis Breaking Down SI: Forming the Question/Hypothesis Question Question Background Information Background Information Hypothesis Hypothesis Homework: Homework: Return parent permission slip (Golden Ticket) Return parent permission slip (Golden Ticket) Project Proposal Outline Project Proposal Outline
Forming the Question/Hypothesis- The Question A good scientific question cannot be answered with a simple yes or no! A good scientific question does NOT use the words “better” or “best,” because better or best are not measurable! “Which” or “How does” are the easiest question words to start a scientific question! Practice: Write 3 good scientific questions from this list of topics: Baseball, pasta, salmon Example: Which pasta type, spaghetti or angel hair, will cook the fastest? Breaking Down SI
Forming the Question/Hypothesis Forming the Question/Hypothesis- Background Information (Research) Gathering information about your subject to make an educated statement or hypothesis. I MUST cite ALL my sources!!! Sources are where you get this information is yourself, Internet (specific web address w/date), videos, TV, media, books, object or subject, other people, interview. Practice: Write all you know about: baseball, pasta, or salmon Example: An average spaghetti noodle is 2mm in diameter and 20cm long. An average angel hair noodle is 1mm in diameter and 20cm long. Pastas are flour based starches that are dried and then boiled in water for preparation. Once a noodle is boiled in water it becomes smooth and slippery, but if allowed to dry gets sticky. Breaking Down SI
Forming the Question/Hypothesis Forming the Question/Hypothesis- The Hypothesis An educated answer to a question. Always explain why you think “this” will happen using your background information. What is going to happen in your experiment and why it will happen. Practice: Write 2 hypotheses using your questions above. Example: The angel hair pasta will cook faster than the spaghetti, because it’s diameter is smaller than the spaghetti so there is less pasta to be cooked. Example: If the diameter of the pasta is smaller, then the pasta will cook faster because there is less pasta to cook. Breaking Down SI
Day 6 Breaking Down SI: Designing the Investigation (Investigation is also known as your EXPERIMENT) Breaking Down SI: Designing the Investigation (Investigation is also known as your EXPERIMENT) Materials List Materials List Procedure Procedure Understanding Variables and Controls Understanding Variables and Controls Understanding Types of Variables Understanding Types of Variables Homework: Homework: Return parent permission slip (Golden Ticket) Return parent permission slip (Golden Ticket) Project Proposal Outline Project Proposal Outline
Designing the Investigation: Materials List and Procedure Materials List: (What you need to do the experiment) Needs to be in list or bullet form. Procedure: (What you do with the materials, the instructions to do the experiment, Numbered Step-by-Step) or more trials 5. Practice: What is the materials list and the procedure for making a peanut butter and jelly sandwich or Kraft M&C ? Breaking Down SI-
Just do it! Plan whatever you are going to do and do it! Collect data and make observations along the way. Breaking Down SI- Designing the Investigation: The Experiment
Control is the “normal” in which the experiment would happen, what you are comparing too. Example: a plant needs the right amount of sunlight, water, space and temperature to grow properly, when racing a non windy and non rainy day are ideal for the experiment. Control is the “normal” in which the experiment would happen, what you are comparing too. Example: a plant needs the right amount of sunlight, water, space and temperature to grow properly, when racing a non windy and non rainy day are ideal for the experiment. Variables are the things in an experiment that can change. Example: height the ball is dropped from, how far the ball bounces back up, the temperature of the green house, how tall the plant grows, the distance from the target, how deep the arrow penetrates. Variables are the things in an experiment that can change. Example: height the ball is dropped from, how far the ball bounces back up, the temperature of the green house, how tall the plant grows, the distance from the target, how deep the arrow penetrates. Designing the Investigation: Understanding Variables and Control Breaking Down SI-
Control Control Why is this considered a control? Are there any variables in this picture? What are the possible variables? This is considered the control because it shows the “normal” items necessary to grow a plant
Which variable is changed in each picture? Control Control
2 Types of Variables (2 flipper in toolkit) The Independent Variable is the variable that you choose to change of all the available variables. The Independent Variable is the variable that you choose to change of all the available variables. Example: Racing cars Example: Racing cars Ramp height Ramp height Ramp distance Ramp distance Car body shape Car body shape Car mass Car mass Surface car rolls over Surface car rolls over The Dependent Variable DEPENDS on the changes of the independent variable. The Dependent Variable DEPENDS on the changes of the independent variable. Example: Racing cars Example: Racing cars How far the car travels How far the car travels How fast the car travels How fast the car travels Independent Variable Dependent Variable
Which INDEPENDENT variable is changed in each picture? Control Control
What happens to the DEPENDENT variable in each picture? Control Control
IF, Then, Because Variables If the independent variable is changed…, then the dependent variable will…because explain using support from background information. If the independent variable is changed…, then the dependent variable will…because explain using support from background information. Example: Example: IF the height from which the ball is dropped is increased, then the height the ball bounces back up will increase because the higher the ball the more momentum and force it will have to bounce back up. IF the height from which the ball is dropped is increased, then the height the ball bounces back up will increase because the higher the ball the more momentum and force it will have to bounce back up.
Understanding Independent Variables How many independent variables should be changed in an experiment? How many independent variables should be changed in an experiment? Why is this important? Why is this important? 1 If more than 1 independent variable is changed in an experiment, how do you know which one caused the results? It is important to know which independent variable was changed to know what caused the results!

Day 7 Breaking Down SI: Collecting and Presenting Data Qualitative Data Observations Quantitative Data Measurements in a DATA TABLE Graphing the data table Homework: Rough Draft of Science Project Due Monday, November 2, Rough Draft of Science Project Due Monday, November 2, 2015.
Collecting and Presenting the Data Observations (Qualitative Data) Qualitative Data: Information gathered through observations Observations: Using the 5 senses to gather information about what is occurring in the experiment. Practice: Observe the object on your table, and write down your observations. Different ways to record observations: Table Categorically Random Notes Graphic Organizer Sketch Breaking Down SI
Collecting and Presenting the Data Data Tables(Quantitative Data) Data tables are boxes with numbers in them (where data is collected), one axis shows the dependent variable the other axis shows the independent variable. Practice: Draw a data table that shows the growth of 3 plants over time. (Bean plant activity) Growing Plants Together (Height in mm) Pot APot BPot C Days Breaking Down SI
Collecting and Presenting the Data Graphs (Presenting Data) Data tables are difficult to interpret patterns, so turn your data table into a graph. Again one axis shows the dependent variable the other axis shows the independent variable. Practice: Draw a graph that shows the growth of 3 plants over time. (Bean plant activity) Breaking Down SI
Day 8 SI Breakdown: Analyzing the Interpreting the Results Summarization Hypothesis Correct or Not and WHY Review for Errors and Limitations Homework: Write your science project paper rough draft. Write your science project paper rough draft. Due Monday, NOVEMBER 2, 2015!
Analyzing and Interpreting the Results (The Conclusion) Summarize the outcome of the data, then look for and explain any patterns in the data. Explain how the data supports or refutes the hypothesis.
