STEM Fair will be held on March 6, 2012
We need judges for the Science Fair. Please sign up if you are interested in helping out!
Students participated in a Science Fair Kick-Off January 6, with Ms. Zizzle.

Student Journal• Each student receives a science fair project journal
that takes the student step-by-step through the process.
• It is the place to keep track of the project steps throughout the process.
• Gives examples and explanations of each step.• Gives a place for teacher/parent communication.• Gives a place for teacher/student communication.

GES website
• http://www1.pgcps.org/greenbeltes/
• STEM fair 2012 tab• Includes all important
dates• Includes backboard
format to type or print and hand write… the same as what is in the envelopes for tonight
![Page 9: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/9.jpg)
Experiment Time
• Tonight we will conduct a simple experiment and continue through the process of a successful project!
![Page 10: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/10.jpg)
Find the Grey Envelopes
• In each envelope are some supplies.
• On the table in the front of the room are supplies you can use also.
• Talk in your group and discuss an idea you can test.
• We are going to try a new strategy the Four Question Strategy for the Scientific Method
![Page 11: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/11.jpg)
The hardest part is getting started
• We are going to use a Four Question Strategy
• Step One- What materials are available for conducting experiments on the topic Magnetism?
• Look in the grey envelope• Write a list of materials you see and others
in the environment (you cannot see)
![Page 12: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/12.jpg)
Step Two
• How does topic magnetism act?
For example: How do batteries act?- give energy to make things work
Example: How does soil act?- helps roots grow, feeds earthworms
![Page 13: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/13.jpg)
Step Three
• How can I measure or describe the response or action of the topic magnetism to change?
• This is the data collection phase
• Think…What can I measure?
(time, length, height, etc.)
![Page 14: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/14.jpg)
Step Four
• Look back at Step One• How can I change the set of materials to
affect the action or behavior?• create a list of possibilities with each
material• (this is the possible variables) • You can only pick ONE difference • EVERYTHING Else is the SAME
![Page 15: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/15.jpg)
Now… Pick ONE idea to test
Creating the Question– Use the material (variable in Step Four) and
how the change will be measured (Step Three).
• Question format: Does the (material) affect (magnetism ) (behavior)?
• Write the Question on the question page
![Page 16: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/16.jpg)
Hypothesis/ Prediction
• Answers the Question
• It is what you think is going to happen
• To write the hypothesis-
• (material or independent variable) does/does not affect the (what is measured- dependent variable) of topic (magnetism)
![Page 17: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/17.jpg)
Materials
• List materials needed for YOUR experiment
• Use amounts and units
• Use metric measurements if possible
![Page 18: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/18.jpg)
Variables
• Identify manipulated (independent)- what you change on purpose
• Identify responding (dependent)- what you think will change
• Identify control (the same)- what you want to keep the same
![Page 19: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/19.jpg)
Procedures
• Write step-by-step directions anyone can follow
• Start with a VERB, a direct action
• Include repeating trials
• Follow your steps and conduct the experiment
![Page 20: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/20.jpg)
Experiment time!
• Conduct your experiment
• Follow the directions you wrote
• Don’t forget to record your results in the data table
![Page 21: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/21.jpg)
Step #6
Results• Collect measurable data -usually in
numbers (length, height, time, etc…)
• Keep a written log of observations
• Take pictures
• Draw charts, data tables, graphs
![Page 22: Greenbelt Elementary School Parent Experiment Night 2012 Science Coordinator Vanessa Zanin](https://reader035.vdocuments.site/reader035/viewer/2022062806/5697bfbd1a28abf838ca1f02/html5/thumbnails/22.jpg)
Step #7
Conclusion• Before you write look back at your data and ask
questions• Was the hypothesis correct or incorrect?• What is the answer to my question?• Were there any problems? What would I like to
investigate next? • How does it apply to the real world? Answer these questions into several paragraphs.

Step #8
Research• Use a variety of resources (at least 3)• Books, magazines, videos, Internet • Find information related to your topic and
discover how your topic relates to the real world• Write in your own words about the information
you found (include your sources)

The day of the fair: March 6, 2012
• Projects will be due into the school on February 27 so that there is time for oral reports and to get the fair set up
• Volunteers come judge the projects by interviewing the students
• That evening the fair will be open for families to view the projects
