Testable or Not? How is bug blood different from human blood? Yes!
10
Testable or Not? 2. Why do your fingers wrinkle after you take a bath? What wrinkles your fingers faster, salt or freshwater? How long does it take your fingers to wrinkle in water?
11
Testable or Not? 3. Is rock music better than hip hop music? How many people at Kenwood prefer rock music over hip hop? What effect does the genre of music have on your ability to concentrate?

15
Now that you have identified testable from non-testable questions, the next step is……
16
How do I write my own testable question?
Ask your 4 questions. (The 4 Step Process)
17
1. What materials are readily available to conduct an experiment on pillbugs?
Scales Thermometers Beakers pH paper Colored paper Water Vinegar Heat lamps Graduated cylinders
18
2. How do pillbugs act? Roll up in ball Drink from anus
Hide under rocks Eat their own poop Breathe through gills Crawl Shed their skin Carry eggs in brood pouch Turn blue when sick
19
3. How can you change the set of materials in #1 to affect the action in #2?
Water Temp Quantity Foreign substance pH Light Temperature Amount (intensity) Direction color Beaker Size Contents Clean Paper Type Color material texture
20
4. How can you measure the response of the pillbug to the changes in #3?
Time them Measure their length How fast they role up How fast they crawl Measure their shape/size
21
Let’s write our testable question…
Format: How does (pick a change in #3) affect (pick an action in #2)? Example: How does the type of paper affect the speed of the pillbug?
22
Homework Write 3 more testable pillbug questions using the 4 step process on looseleaf.

The Process of Scientific Inquiry
Topic Selection Get to know your topic better Choose a testable question to answer Predict the answer (Hypothesis)
28
Writing a hypothesis A educated guess about what is going to happen
Independent Variable (what you are changing) Dependent variable (what you are measuring) "If _____[I do this] _____, then _____[this ]_____ will happen, because… A educated guess about what is going to happen It’s an educated guess because you have already completed your background research Keep the variables in mind. The dependant and independent variables should be clearly stated Make sure your hypothesis is "testable.“ A hypothesis explains why you anticipate the outcome you have stated
29
Example of hypothesis "If a plant receives fertilizer, then it will grow to be bigger than a plant that does not receive fertilizer. This is likely to happen because… What are the independent and dependant variables? Independent variable = Dependent variable =
30
Re-write this into a hypothesis
Ladybugs are a good natural pesticide for treating aphid infected plants. Hypothesis: If I treat the plants with ladybugs, then the number of aphids will decrease because ladybugs are good natural pesticides.
31
Let’s practice writing a hypothesis to our testable question!

The Process of Scientific Inquiry
Topic Selection Get to know your topic better Choose a testable question to answer Develop a way to answer the question (Procedure) Predict the answer (Hypothesis)
38
Writing Procedures 1. Should be very specific, telling the person exactly what to do. (The reader should be able to complete the experiment by reading your directions). 2. Steps should be written in complete sentences and numbered in sequential order. 3. Should be written in the 2nd person as if you are talking to the reader.

Live Organism Treatment
Pill bugs are living creatures – treat them with care. Do not touch them with your hands, use a q-tip or paint brush to redirect their path. Pillbugs need to be used for future classes today!
