Teacher's Guide & Materials [PDF]
1. In a group of 3 - 4 students [can be done
individually], look over the following
webpage.
You will need water, antacid tablets [or Vitamin C tablets], 2 cups, an
envelope [or mortar and pestle], a stop watch or use your timer on your
watch or iPad; and, allocate one student to video the experiment.
Instructions from the website:
2. Research Phase
Read the materials provided to you by your teacher. If you have access to
the internet, also explore resources at www.trynano.org.
3. Hypothesis
As a team, decide what if anything you think might happen differently when
water is added to a whole antiacid tablet or when water is added to a
crushed or crumbled up antacid tablet. Write a
sentence or two describing your team's hypothesis.
4. Test
Now, test your hypothesis! Place one whole tablet in one of the two cups
provided to you, and crush another tablet inside an envelope to help contain
the crumbled parts. You may also simply crack the whole tablet into ten to
fifteen smaller pieces if you like. Drop the crumbled tablet into the second
cup. Then add about 150 ml of water to each one. Video
the whole experiment so you can compare the reactions. Don't forget to time
the reactions.
5. Observation and Results
Observe and discuss what happened -- if anything -- and compare the results
with your team's hypothesis. Look at the videos
of these reactions and compare them.
Was there a difference in the timing of each experiment?
6. Presentation and Reflection Phase
Present your original hypothesis and experiment observations to the class,
and listen to the presentations of the other teams. Then complete the
reflection sheet.
7. Reflection
Complete the reflection questions below:
A. How accurate was your hypothesis compared to
what happened?
B. What surprised you about what you saw?
C. What other hypotheses were developed by other
student teams?
D. What do you think might have happened if you
used a larger whole tablet instead? What about if you were able to crush the
tablet into a powder?
E. Did you think that working as a team made this
project easier or harder? Why?
F. Give an example of how surface area impacts
another material.
8. As a Pharmacologist, what are the implications for
your recommendations on how a medicine should be taken? Provide examples.
