The Feely box--An observation activity
STANDARD: 3200 - 01
Students will evaluate the particulate nature of matter.
Objective: 3200-010 Analyze evidence about particles
of matter.
Compare and contrast through observation the
properties of various common substances.
Intended learning outcomes:
1. Use Basic Science Process Skills
1 a. Make observations and measurements (uses instruments as
appropriate).
2 b. Develop and use categories to classify observations.
3. Manifest Scientific Attitudes and Interests
3 a. Maintain a sense of curiosity about natural phenomena.
Teacher Preparation:
Materials needed:
1 Sturdy cardboard box made into a feely Box.
To make a feely box get a box narrow enough
that the student can comfortably put both hands into the box through
holes on both sides of the box. Cut the holes, then rig some fabric
sleeves in the holes so that the students cannot see into the box. This
can be done by poking the shoulder part of the sleeve through the hole
to the inside of the box, cutting some tabs on the end of
the sleeve and then gluing them around the hole. Old shirt sleeves,
old pant legs etc. Have worked great. Also fix the top of the box so
that they cannot see into the box.
Several Mystery objects that will fit into the box with
room for the student to explore the object by touch.
Try to find objects that you dont think the students will recognize.
You may want to do things to your mystery objects to disguise them
like putting a marble in a balloon partly filled with water and then
tying an old nylon sock on the outside.
***Caution*** Do not use objects
that can cut or pinch students.
Teacher instructions:
During this activity you will be trying to help the students to learn
to use other senses than their eyes.
-
It is important not to tell or show them what was
in the box when they are done.
-
One of the skills students need to learn is to
observe indirectly. This may be very hard for the students.
-
It is important that the students you choose to
explore the feely box for the group understand what
a property is. They will only be able to describe the mystery
objects by giving that objects properties, things that describe
such as texture, size, hardness, etc, to the class.
-
You may choose to put more than one mystery object
in the box at the same time. The feeler should not distinguish between
the objects. If the feeler uses sizes as a property have them use
standard measurements, not comparisons with other objects.
-
It is important that students hold their class discussion
until discussion time.
-
After several feelers have exhausted their supply
of clues to the rest of the class, have the students take five minutes
and form a hypothesis on what they think the object was and what it
looks like.
-
After five minutes open up a class discussion where
all students have the opportunity to show their picture and tell what
they think the object is.
-
After every one has had their say give them time to
revise their hypothesis.
-
Have the class come to a consensus as to what is in
the box.
Student instructions:
Some of you will be chosen to be feelers as we explore
the contents of the feely box today.
-
It will be very important that you do not tell the
class what is in the box.
-
Your task is to be the eyes, reporting
to the brain (the class) what you see (feel).
-
You may only tell the class properties, characteristics.
or traits, things that describe such as texture, size, hardness, etc.,
of the object inside the box.
The duties of the class members during no discussion time are:
1. Write down all the clues you get from the feeler
about the mystery object today.
2. When you have as many clues as you can get, form a hypothesis and
draw what you think the mystery object looks like.
During class discussion time
3. Show your picture and tell what you thought the mystery object was.
4. Make adjustments to your hypothesis as the need arises during the
discussion.
5. Help the class come to a consensus as to what the mystery object
really was.
6. Write a summery of what you learned during this activity, include
frustrations and triumphs.
