STEM Fair Log
Required for all projects
STEM Fair Log• You will keep everything you do and think
about your STEM fair project in your log.
• Your log is like a diary or journal of your progress in your investigation.
• Keep everything you write in your log even if you change your mind or start over.
Day 1 Entry:• Write today’s date on the first
page of your log.
• Write what you know, think, and wonder about science fair.
Log Expectations• Projects without logs will be disqualified.
• The log IS the project. The show board is just a commercial for the project.
• Each entry should be dated.
• Research notes, measurements, observations, and test results should be included.
How to Select a STEM Fair Topic
Restricted Topics• Projects involving blood, bacteria, mold or
fungus.• Projects using guns or explosives.• Projects causing harm to animals.
Animals
• Permission must be given prior to the start. – Human / Animal Form
• No surgery or dissection may take place
• Neither physiological or psychological harm to the animal can result
• Must be supervised by an adult.
Brainstorming Topics(Grades 3-5)
Help your child make a list of things they are
interested in or have questions about.
Brainstorm at least 10 to get started.
Help your child think of questions …. Things I Like Questions
Baseball Does a baseball roll farther on artificial grass?
Paper Airplanes How does the shape of the wing affect the glide? Rocks Do rocks erode more when exposed to acid rain?
Playing outside What color shirt will keep me cooler outside in the sun?
Creating a testable
STEM Fair question
STEM Fair Questions
How does the type of water affect the growth rate of a plant?
How does the species of the orange affect the amount of juice it has?
How do shade trees affect temperature of areas on our playground?
What is a Good Question?
A good science investigation question:• Can not be answered with one word such as
yes or no. • Tells you what you need to measure.• Is something you can investigate yourself.• Is answered with data that is collected.
Identifying the
Purpose
Research
Research
• Before the project begins, learn more about the topic.
• Include the information learned in the STEM fair log.
• This information will be used to develop the hypothesis.
Hypothesis
ProcedureMaterialsVariablesDirections
Example of Materials List
Materials• 2 – 16oz Office Depot clear plastic cups• 130ml tap water• 1 Thermometer • 16 oz of ice from cafeteria ice maker
• *Include how and when materials were obtained
Examples of Directions1. Gather Materials2. Fill cup to ½ way mark with ice.3. Add 130 ml of tap water4. Swirl cup for 1 minute. (hold by top edges
of the cup)5. Record water temperature. (Keep
thermometer in water, look at eye level)6. Add 2 more ice cubes.7. Repeat steps 4 and 5
DATA
DATA•Data refers to the information gathered in the investigation
•This is in the form of tables and charts.
•You can also use photographs or drawings to show the information you gathered but pictures do not replace the data.
DATAThe more trials you do the more accurate the results of your experiment will be.
The minimum for STEM fair is five trials.
Scientists often repeat experiments thousands of times.
Distance a toy car will Roll in Meters
Graph
Graph Use a bar graph or line graph to display data.
This is the same information gathered and already
recorded on your data chart.
