How do I write my own testable question?

Ask your 4 questions. (The 4 Step Process)

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

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

3. How can you change the set of materials in #1 to affect the action in #2?

Water• Temp• Quantity• Foreign substance• pHLight• Temperature• Amount (intensity)• Direction• color

Beaker• Size• Contents• CleanPaper• Type• Color• material• Size• texture

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

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?

Homework

– Choose one of the 3 testable questions you wrote for homework about pillbugs

– Write that question that you are interested in testing on the little strip of paper

– Go through the “testable question” checklist to determine if your question is testable

Tuesday Sept 13, 2011

OBJECTIVES:• Develop a testable

question for the pill bug lab

• Determine the features of a hypothesis

• Determine the features of a well written procedure

The Process of Scientific Inquiry

Choose a testable

question to answer

Predict the answer

(Hypothesis)

Get to know your topic better

Topic Selection

Writing a hypothesis

"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

Dependent variable(what you are measuring)

Independent Variable (what you are changing)

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 =

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.

Let’s practice writing a hypothesis to our testable question!

not?

2. Turn that question into a testable question and write it on a sheet of looseleaf with all your names

3. Explain how that question qualifies as a testable question

4. Turn your group’s testable question and hypothesis in to me for review.

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! – Do NOT pick them up – transfer with index card.
