Projectile Sled Project for Projection
The Projectile Sled Project will help students learn visually and tactually about motion and force.
Objectives:
1. Work in teams
2. Collect useful data for analysis.
3. Use data and plot for analysis.
4. Use data to predict a future out come.
5. Test prediction.
The purpose of the Projectile Sled Project is to have students work together to launch a small projectile repeatedly using various forces and gather the necessary data to set up a mathematic equation to predict future outcomes, then test these predictions.
A Team consists of the following positions with at least these responsibilities:
· The Marker:
o Follow all safety guidelines
o Know the location of all the participants
o Memorize
and follow Marker Safety
guidelines and procedures
o Mark the location where the projectile hits
the ground
o Help measure where the projectile lands
o Help with data collection, analysis and
predictions
o Make and Collect and Keep Landing Markers
· The Timer / Recorder:
o Follow all safety guidelines
o Know the location of all the
participants
o Memorize
and follow Timer / Recorder
guidelines and procedures
o Keep the written record of all data
collected and turn in at the end of the project
o Enter all data into Excel spread sheet and
submit to online folder
· The Releaser:
o Follow all safety guidelines
o Know the location of all the
participants
o Memorize
and follow Releaser guidelines
and procedures
o Help measure where the projectile lands
o Help with data collection, data entry and analysis
and predictions
· The Puller:
o Follow all safety guidelines
o Know the location of all the
participants
o Memorize
and follow Puller guidelines
and procedures
o Help measure where the projectile lands
o Help with data collection, data entry and analysis
and predictions
Each team must
have at least one team member qualified for each of the above
responsibilities!
Any team member may
qualify for more than one position.
Each team must have
at least 3 different people qualified for at least one of each of the 4
different positions (one Marker, one Timer/Recorder, one Releaser, and one
Puller). Teams that do not have at least one of each of the four will be
reassigned to another team.
Anyone who does not qualify for at least one position will be given
alternant assignments.
This is a check list. Use it to get organized and ready for:
1. Testing days
Materials:
Each team will need to obtain the following before they will be allowed
to practice on the sleds.
Each Team member will be assigned a position they will learn, be tested on, train at and must qualify for.
Each Team member may learn, be tested on, train at and qualify for any and all other positions.
Only tested, trained and qualified persons will be allowed to participate in Projectile Daze
Only a tested, trained and qualified person will be allowed to perform the job(s) he/she has been trained to do.
