Grades 912 Performance Task
Contributed by: Kentucky Department of Education (KDE)
Description:
Students use data from an experiment to draw conclusions about how
a product will work. They will collect and analyze data and study
wavelengths of visible light.
Students set up equipment according to a diagram and perform an
experiment by recording the temperature of three differentcolored
cups every 30 seconds for eight minutes. Individually, they organize
and analyze the data, using it to make a recommendation on the design
of a sunfiltering product.
This task is designed to take students approximately 4050 minutes
to complete. The activity portion is done in small groups for up
to 20 minutes. The followup questions are completed individually
by each student working alone.
Overall Task Content Area:

 Physical Science
Specific Knowledge Areas:

 Interactions of energy and matter
 Conservation of Energy and the increase in disorder
Performance Expertations:
 conducting investigations
 using equipment
 gathering, organizing, and representing data
 formulating conclusions from investigational data
 applying scientific principles to develop explanations and solve
new problems
National Science Education Standards:
12 B PS 5: Conservation of energy and increase in disorder:
Grades 912
5.3 Heat consists of random motion and the vibrations
of atoms, molecules, and ions. The higher the temperature, the greater
the atomic or molecular motion.
12 B PS 6: Interactions of energy and matter: Grades
912
6.1 Waves, including sound and seismic waves, waves
on water, and light waves, have energy and can transfer energy when
they interact with matter.
12 A SI 1: Abilities necessary to do scientific inquiry:
Grades 912
1.4 Formulate and revise scientific explanations and models
using logic and evidence. Student inquiries should culminate in
formulating an explanation or model. Models should be physical,
conceptual, and mathematical. In the process of answering the questions,
the students should engage in discussions and arguments that result
in the revision of their explanations. These discussions should
be based on scientific knowledge, the use of logic, and evidence
from their investigation.

General Instructions to the Teacher:
This task is designed to take students approximately 4050 minutes
to complete.
Students work together for up to 20 minutes. They are instructed
to notify you when finished with the group work, and then to go
on to the individual work inside the "Student Response Form." If
students are still working together 20 minutes after the testing
begins, instruct them to cease their group work and begin individual
work. At this point, students should open their Student Response
Forms. They may no longer talk. Whether or not they are just beginning
their individual work, remind students that they now have 25 minutes
to complete the individual activity.
Students should be ready to work as soon as the period begins.
Group assignments should be made in advance. The materials should
be set out at each lab station, if possible. A central supply area,
if needed, should be easily accessible. All supplies should be clearly
labeled.
Materials for "Let the Sunshine In":
At this station students should have:

 One Student Response Form and one Data Sheet for each student
One stopwatch
Three styrofoam cups with colored covers (one each red, yellow,
purple) secured
One lamp with 100watt bulb
Ring stand
Metric ruler for each student
Three lab thermometers
Four sets of colored pencils
Sharpened pencils
Advance Preparation:
Secure the colored covers to the cups with rubber bands. Insert
one thermometer into the side of each cup as shown in the diagram.
(seeDirections to the Student) Make sure to locate this task
near an electrical outlet. Make sure there is a bulb in the lamp.
Plug in the lamp and extension cord (if needed) to make sure the
cord reaches the outlet safely and the equipment works.
Safety:
 Be careful.
 Teachers and students should always exercise appropriate safety
precautions and utilize appropriate laboratory safety procedures
and equipment when working on science performance tasks.
