8/21­ How fast does a pillbug go? lab
To compare the speed of two things, you need to make sure the speed of each thing
is in the same unit. In order to compare the speed of a pillbug and another animal,
you will most probably need to convert the average pillbug's speed to kilometers per
hour (kph).
To do that, you need to:
Average pillbug speed (in cm/sec): ________
______ per sec x 60= ______________
______ x 60= _______________
______ / 100,000= _________ kph

FINISH YOUR LAB...You have 7 minutes.
8/21 and 8/25­ How do I write the conclusion for the How
Fast Does a Pillbug Go lab?
1. Pick an animal.
2. Write a sentence that makes a claim on your lab sheet about its
speed compared to a pillbug.
3. Research the speed of the animal you chose.
4. Write 2 sentences stating the data needed to support your
claim...one about the pillbug's average speed and one about your
chosen animal's average speed.
5. Write a sentence that explains how your data supports your
claim. This is the part that challenges students because it requires you to do your own thinking. Imagine that!! :) I
want you to do your own thinking! Try it on your own...write SOMETHING, even if it's wrong!!!

Which of these methods for comparing the absorbency of
paper towels will give the most reliable* data? Explain your
thinking. * Reliability refers to how well a test gives the same results when it is repeated multiple times.
1. Pour 50 mL water on the counter. Use a 20 cm x 20 cm square of
paper towel to wipe up the water. Measure how much water is left on
the counter.
2. Put a 5 cm X 40 cm rectangle of paper towel into a graduated
cylinder that has 50 mL water in it. Measure how long it takes for the
water to go 30 cm.
2. Put a 5 cm X 25 cm rectangle of paper towel into a beaker that has
500 mL water in it. Measure the distance the water travelled in 2
minutes.
3. Measure the mass of a 20 cm x 20 cm square of paper towel. Put the
paper towel in 100 mL water. Measure the mass after one minute.

a. Clearly define below what your experiment will test to find the
“most absorbent” paper towel (it usually involves measuring
something to find out).
____________________________________________________________________

b. *Write your problem statement in the form of a question.
*Remember that your problem should not have a “yes” or “no”
answer.
*Begin the problem with a word such as how, which, or what. Your
question should not be researchable (What mountain is the tallest?).
EX. Does a liquid freeze more quickly if it starts out at room
temperature or colder than room temperature?

b. Beginning with the source citation, answer your testable
question using the research. EX. If your testable question is
“Does a liquid freeze more quickly if it starts out at room
temperature or colder than room temperature?,” you would
present your research like this: “According to page __ of the
Matter and Energy textbook, the molecules of a liquid at
room temperature ___.” RESTATE the research exactly as it

3. HYPOTHESIS
Remember that a hypothesis includes a tentative explanation
for an observation or scientific problem.
EX. “If 100 mL of 27oC orange juice (o.j.) is put in a 0oC freezer,
What you’re going to do (IV)
then it will freeze more quickly than 100 mL of 20oC o.j.
What you think will happen based on the research (DV)
because the molecules of a liquid at room temperature _blah, blah, blah_.”
Why you think that will happen (research)
Write your hypothesis below in the form of an "If ____, then
____, because ___." statement. Make sure your hypothesis is
specific (include necessary materials and procedures).

RESEARCH for Paper Towels Don’t Suck! lab
Source #1: from: <hp://www.educaon.com/science‐fair/arcle/find‐absorbent‐brand
paper‐towels/>
Paper towels are permeable and porous, meaning that they contain small spaces that
both liquid and air may pass through. Liquid is able to rise through a property of water
called cohesion­that is, water molecules like to stay close to one another (which also
helps to explain surface tension). Water also likes to bind to certain other materials
through a process called adhesion. (Adhesion is what causes a meniscus in a graduated
cylinder (gc). The water molecules adhere to the plastic or glass of the gc.) In this paper
towel science project, we will be testing which type of paper towel contains the highest
rate of capillarity (or ability to absorb water into its many small spaces).
Source #2: from: <hp://science.howstuffworks.com/diconary/physics‐terms/capillary
acon‐info.htm>
Capillary Action, or Capillarity, the tendency of liquids to rise or to be depressed in tubes
of small diameter. Capillarity is due to the adhesion of the liquid to the sides of the tube,
and to the surface tension of the liquid.
A liquid that wets a capillary tube will rise. If the liquid does not wet the tube it will be
depressed. The smaller the diameter of the tube, the greater the elevation or depression
of the liquid. As temperature increases, the amount of elevation or depression decreases.
Capillary action can be seen when a corner of a paper towel is touched to spilled water.
The water soon spreads into other parts of the towel because loose fibers have spaces
between them that act as capillary tubes. The drying action of a bath towel is also due to
capillarity. Kerosene rises in the wick of a lamp through capillary action.
Source #3: from: KClassScienceChannel
<hps://www.youtube.com/channel/UCOK5U
tQfmgA6FnCxNPr_IQ>
Source #4: from:
hps://en.wikipedia.org/wiki/Capillary_acon
Capillary action (sometimes capillarity, capillary motion, or wicking) is the ability of a
liquid to flow in narrow spaces without the assistance of, and in opposition to, external
forces like gravity.
