This is our first video showing
how we do science.
We were trying to show how to lift a book using
a lever. You can watch the movie. Then read what we used to do the
experiment.

How we did the experiment was, we took
a fulcrum, lever, some mushrooms a basket and a World
Book Encyclopedia. The encyclopedia was the letter D.
The fulcrum was a wooden triangle. The lever was a flat
board. It took 273 mushrooms in the basket to lift the
book.

This is how we counted the mushrooms
after we were finished. We then checked to see if we put the
same number in each group. We had 11 in one group and had to
move one to the left over group.
|
|
We divided the mushrooms into groups
of 10. The last group only has 3. You can see how many
mushrooms there are in all. It took 273 mushrooms to lift
the basket to lift the D encyclopedia.

changed.
K Scientific Reasoning
Students will learn to formulate and justify ideas and to make
informed decisions.
3. Make observations
5. Use various forms of simple logic
6. Discover relationships and patterns.
L. Communication
Students will communicate effectively in the application of science
and technology.
1. Describe and compare things in terms of number, shape, texture,
size weight, color, and behavior.
