is a good lesson for the beginning of the scientific method, it also works just
for the first day of class for students to get to know one another.
- Start by gathering up things that
are oddly shaped, it is important for the grade level to find things that
students can't easily identify (take a trip to a hardware store), that way
they must rely entirely on the description of the object to convey what it
- Students will have an object at
their desk when they enter class, they are instructed to write onto a piece
of paper as much as they can to describe they object they have. They are NOT
to put their names on this paper. When finished, they are to fold the paper
into quarters and turn the description in.
- Option 1 - All items are gathered
at the front of the class. You read off the students' descriptions and see
if the rest of the class can match it to the correct object. I use this option
for large classes that I don't want moving around very much.
- Option 2 - Take the papers and
hand them out at random. Students then must wander around and try to match
the description to the object. Students generally enjoy this option better,
requires more classroom management.
Another Variation on this lesson
uses small jars (I use specimen jars, but baby food jars would work also) and
fill them with various household liquids and food coloring. The same principle
above applies, only the have to find the jar with the liquid described by someone
else. This one also incorporates the sense of smell. I try to fill the bottles
with mixtures that have lemon juice, perfume, vinegar and other "smelly"
things. The students seem to enjoy this one.
