Water Activity
Instructions.
Use your notebook for recording data,
answering questions, etc. You will use this information
when you do your lab write-up using the hand-out I gave you
earlier.
1. Write a
Guiding Question such as “What type of container,
when filled with water will hold the most pennies before
overflowing?”
2. Sketch
each container on paper and label them A, B, C, D and E
(this is part of your data)
3. Choose
a partner and get a glass of water from me. Use your senses
of touch and sight to make as many observations as you can
in 3 minutes. You should have at least five observations
(more data)
4. Create
a hypothesis based on your sketches as to which container
you think will hold the most pennies. (This will be part of
the hypothesis portion)
5. With a
penny, pipette, and a paper towel, see how many drops you
can fit on a penny before it over flows. You should do
three trials and find the average drops. Each student must
write a procedure for the test before performing the task.
It must be a step by step procedure that includes all
materials you will be listing. The teacher must check your
procedure before you can conduct the tests. All data must
be written down so you can use it later in the lab write
up. You will have 10 minutes, so you cannot waste time.
You should make some observations that describe what you see
or observe as the water piles on the penny (data).
6. Post
your average. Compare your average with other groups.
Answer the questions “Why do we have different results if we
all have the same materials to work with?” and “How could we
do this and have a control to insure that the results are
consistent?” (You will use these ideas in your lab
conclusion write-up at the end of the activity)
7. Get a
nickel and make a prediction on how many drops it will hold
based on your results with the penny. Follow the same
procedure you did with the penny. Record all results
(data,)
8. Compare
your results between the penny and the nickel. Are the
results the same? Why or why not. Write down all factors
you can think of that caused your penny to be different from
your nickel. Make a generalization about the number of
drops that would fit on a quarter if we were to follow the
same procedure. If you don’t remember what a generalization
is, look it up in your book. Be sure to defend your
generalization using data collected during our
experimentation.
9. Do you
need to change your original hypothesis? Explain why you
changed it or why you stayed with your original hypothesis.
This information will also be part of your write-up
conclusion.
10.
Observe as we put pennies into the containers until they
overflow. Record your data.
11. Is
there anything that you could do to the water that would
change the amount of pennies that could fit into the
container? What are your ideas? This will also go into
your conclusion.
