Data Collection
Community School for Social Justice, Bronx
Summer Research Program for Science Teachers
August 2010
Subject:
General Science
Grade Level: 6-12
Overview: This lesson will encourage students to think creatively about collecting data on materials and substances they can’t directly see. Much of science happens at the microscopic, or sub-microscopic level and can’t be directly observed. Other means of observation and measurement, other than our sense of sight, need to be employed in order to collect data in a wide variety of situations.
Objectives: SWBAT:
· Develop methods to record information about materials they cannot directly see
· Apply appropriate labels to their measurements and identify the appropriate measurement tool to use to take the measurement
· Properly use the metic system
Do Now:
Before scientists had the technology to look at the tiny things that make up our world, how do you think they were able to run experiments and collect data? Do Now Worksheet
Materials:
Several closed/opaque containers
to contain various samples for containers to hold various samples
A variety of materials with
differing textures, sizes, temperatures, densities, in differing states of
matter, etc.
Ideas for containers:
o
Shoe box
o
Film containers
o
Plastic (opaque) containers
o
Dark plastic bags
o
Etc.
Ideas for contents:
o
Coins
o
Gum
o
Chewed Gum
o
Soap
o
Water
o
Sand
o
Seeds
o
Ice
o
Heat pad/ ice packs
o
Anything
Instruments for measurement:
o
Balance
o
Ruler
o
Tub of water
o
Thermometer
o
Etc.
Development:
Pre-lab considerations:
1.)
Determine how many containers each group should examine.
A set of containers can be given to each group or a class set of
containers can be created for all groups to share.
2.)
Materials should be placed into containers that are sealed to prevent peaking
3.)
Each container should be labeled to make them easy to differentiate.
Activity:
1.)
Give students five minutes to complete
Do Now.
If students finish early encourage them to be more specific with their
answers.
2.)
Discuss the Do Now. Have students
volunteer answers and create a list on the board of student ideas.
3.)
Explain that as a class students will act as these early ‘blind’ scientists did.
They will be given materials they cannot see that they will need to
collect data about. Discuss what
kind of information you would probably need to collect.
As a class create a data table.
4.)
Explain the rules of the activity:
a. No opening containers
b. Collect as much data as you can about these objects in 20-30 minutes (depending on time available)
Activity
can be made into a competition to award
o
Most data collected
o
Most creative type of data collected
5.)
Share back different types of data groups/students thought to collect
6.)
Compare this list to the list students came up with from the Do Now.
See what similarities and differences there are.
Exit Slip:
Not all data we collect requires us to directly see the object we’re measuring. Name one type of data you collected today and think of a type of experiment where you would collect this kind of data.
Differentiation:
Provide outline of
data
table.
Provide
outline of data table with word bank to use to fill in table.
Group students in groups of mixed abilities and learning styles.
New York State Science Standards:
S6. a. Uses technology and tools to observe and measure objects, organisms, and phenomena, directly, indirectly, and remotely, with appropriate consideration of accuracy and precision.
S6. b. Records and stores data using a variety of formats.
S6. d. Acquires information from multiple sources.
