What is inquiry? Inquiry is a teaching method that engages
learners in authentic investigations in which they identify problems, ask questions, propose solutions, make predictions, design procedures, collect, and organize data, and draw conclusions.
04/19/23 SED AUB 17
What is inquiry - Details A teaching strategy that aims to teach learners
how to conduct investigations and to use and assess evidence in order to answer questions or solve problems.
Primarily aims to develop learners’ higher order and critical thinking skills. Content provides a context for developing and practicing thinking skills. Content and thinking are inseparable.
04/19/23 SED AUB 18
What is inquiry-Details A “genuine” problem is essential for the success
of inquiry teaching in developing learners’ thinking skills:
Learners (and preferably the teacher) do not know and have no access to “the” or “an” answer. They have to reach conclusions based only on their investigations and their data
04/19/23 SED AUB 19
What is inquiry-Details A “genuine” problem (that lends itself to
investigation) guarantees that learners (and their teacher) will have authentic experiences (similar to those of researchers) in assessing the validity of various claims, and adjudicating between contradictory claims concerning a certain phenomenon
04/19/23 SED AUB 20
Inquiry steps Step 1. Framing The Investigation
Step 2: Designing the Investigation
Step 3: Collecting and Presenting Data
Step 4: Analyzing and Interpreting Results
04/19/23 SED AUB 21
Activity 3 Title: How many points are touching?
Materials: A bobby pin (hair pin) for each pair of participants.
Question: Where is it easier to feel the tip of a pin touching your skin, on your hand or near you shoulder?
Hypothesis: What is your hypothesis?
04/19/23 SED AUB 22
Procedure Ask the subject of the experiment to hold out his/her ha
nd with palm up and close his or her eyes Divide the length of the hand and arm into 20 equal
intervals Randomly touch the hand or arm with either one tip of
two tips Ask the subject of the experiment if he is being touched
with one or two tips. Circle the correct or incorrect responses in the following
table. After you have finished colleting data switch roles and
repeat the activity.
04/19/23 SED AUB 24
Follow up questions
Where was it easier to tell how many tips were touching?
Why did we make more mistakes the higher up the arm the pin was touched to the skin?
What makes our touch sense more sensitive?
Where would a cut in the skin hurt most?
04/19/23 SED AUB 25
Hypothesis testing
What pattern can you get from looking at all the results?
Was your hypothesis confirmed and rejected? What evidence do you have for your decision?

The General Inquiry Model
1. Identifying a question or problem The T, the Ss or both generate a problem The problem is genuine and relevant to Ss’ interests
and/or needs (or current/future content) The problem is discussed, clarified, and defined
through discussion
04/19/23 SED AUB 32
2. Forming hypotheses Ss suggest tentative solutions (hypotheses) to the
problem Initially all hypotheses are accepted. Then the
hypotheses are discussed and assessed for relevance and their verifiability with evidence
One or a few hypotheses are selected for investigation
The tentative nature of hypotheses is emphasized

04/19/23 SED AUB 34
4. Assessing hypotheses Ss discuss and analyze their data Ss assess the validity of their tentative hypotheses
based on the collected evidence The logic of hypothesis testing is highlighted
(prove/disprove vs. lend/detract support) and the value of hypotheses (even the ones rejected) in guiding investigations is emphasized.

Activity 5
Title: The heavy newspaper!
Procedure: I will use the thick piece of wood to deliver a strong
blow to the piece of plywood hanging from the edge of the table.
“What will happen?” in what direction will the newspaper fly? To the front? To the back?”
“Think-Pair-Share” this question. Ask them to explain their prediction.
04/19/23 SED AUB 39
Explanation The plywood breaks because the downward force from the blow
of the hammer (or piece of wood) is counteracted by the downward force due to atmospheric pressure acting on the newspaper
Atmospheric pressure is caused by the weight of the air above the surface of the Earth.
Pressure is defined as force per unit area: Pressure (P) = Force (F) / Area (A). The force in this case is caused by the weight of the air above the surface of the Earth. The larger the surface area, the larger the force due to atmospheric pressure
04/19/23 SED AUB 40
Activity 5 Title: The efficient diver
Procedure: What will happen if I squeeze the
bottle in different places Observe carefully what happens and write
down your observations. Use the Think-Pair-Share strategy to and
explain their observations
04/19/23 SED AUB 41
Explanation Squeezing the bottle increases the pressure in the water and
compresses the air inside the pen top. This increases the mass of the dropper but the volume stays the same, therefore its density increases. Note the following:
An object with a density less than that of a fluid will float in that fluid and an object with a density more than that of a fluid will sink in that fluid.
Pascal's law: Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase at every other point in the container.
04/19/23 SED AUB 42
Question
Describe the teaching strategy I used in the previous activities.
04/19/23 SED AUB 43
Predict Observe Explain (POE)
Step 1: Predict Ask the learners to write independently their prediction of what
will happen. Ask them what they think they will see and why they think this.
Step 2: Observe Carry out the demonstration. Allow time to focus on observation. Ask learners to write down what they do observe.
Step 3: Explain Ask learners to amend or add to their explanation to take
account of the observation. After learners have committed their explanations to paper,
discuss their ideas together.
04/19/23 SED AUB 44
Predict - Observe - Explain (POE)
POE can be used for: finding out learners' initial ideas; providing teachers with information
about learners’ thinking; generating discussion; motivating learners to want to explore
the concept; Generating investigations.

Activity 6 Materials:
A round balloon Two small plastic or glass cups (with a smooth rim).
Procedure Blow up the balloon about one third way. Hold one cup in each hand. Hold the cups against
opposite sides of the balloon (while the balloon is in the mouth) and blow further (until about twice the size).
Let go of the two cups.

Learning Cycle
Exploration Learners experience objects and events, discover
patterns and relationships, and are not given answers or labels
Term introduction Learners determine relationships among objects and
events and teacher helps learners construct appropriate labels or provides the labels
Application Learners apply their knowledge of a given concept to
other situations and teacher encourages Learners to discover examples to illustrate the concept or concepts

Activity 8 Why can a person lie down on a bed of nails and not be
injured?
04/19/23 SED AUB 63
ExplanationThe explanation of this phenomenon is related to the fact that
the force per unit area of skin (i.e., pressure) is what determines if a nail will pierce the skin.
The force is determined by the weight of the person lying on the bed of nails.
The area is determined by the effective area of the tip of the nail, or nails, in contact with the skin.
When a 'bed' of nails is used, the same force produced by the weight of the body is distributed over perhaps hundreds of nails. Therefore, the force applied to any one nail is correspondingly reduced, with the result that the force per unit area at the tip of any one nail will be below the level required to pierce the skin. Since this applies to all the nails in the bed, no nail then penetrates the skin.

Teaching Science with Discrepant Events
A discrepant event is a science activity that can create cognitive dissonance in the mind of a learner.
A discrepant event provides the learner with an opportunity to think critically in order to solve a problem
There is an element of surprise in the science activity as the students are watching attentively
04/19/23 SED AUB 66
A discrepant event motivates students to think beyond the obvious
It helps children employ their prior knowledge in resolving the conflict.
While actively engaged in exploring a discrepant event, students have an opportunity to utilize some or all of the science process skills.
Teaching Science with Discrepant Events
04/19/23 SED AUB 67
Suggestions for presenting discrepant events:
Let students replicate the discrepant event. Let them work in groups of 2-4 students.
Ask the students to think and write down their ideas and possible solutions to the inconsistency created by the demonstration
Assess students’ prior knowledge by using a verbal questioning technique. Use variety of questions. Remember Bloom’s Taxonomy.
Teaching Science with Discrepant Events
04/19/23 SED AUB 69
Watch out for students’ misconceptions.
Your questions should represent all levels of Bloom’s Taxonomy
Don’t be so anxious to provide the answer to the discrepant event right away.
Provide many opportunities for students to experience success.

The Futures Wheel
The futures wheel is a teaching technique that encourages students to think creatively in exploring the implications of a particular issue or event.
There are no right answers when completing a futures wheel, and no deSEDion-making occurs.
It is used to analyze issues in preparation for deSEDion-making. Students look at an event, experience or deSEDion and ask "What might happen if...?"
04/19/23 SED AUB 71
Objectives of a Future Wheel
Students will be able to:
Understand that every deSEDion, technological, or scientific development has numerous effects.
Develop a futures wheel to explore the effects of a deSEDion, scientific, or technological development.
Recognize the value of the futures wheel as a tool for thinking about the effects of environmental deSEDion, scientific and technology developments.
04/19/23 SED AUB 72
Conducting a futures wheel activity
1. Explain that every event has an impact on other events or factors. Distribute the handout and show the students how the handout is interpreted beginning at the center circle and proceeding outward.
2. Divide the class into groups of four to six students. Tell the students that they are to select a possible environmental deSEDion, future scientific or technological development as the subject for their futures wheel.
04/19/23 SED AUB 73
Conducting a futures wheel activity (Cont’d)
3. Next students should ask themselves • "What might happen if...?" • Each group should come up with three to five
answers to this question. • Explain that these first responses are called
the first-order connections. • A circle should be drawn around each
response, and a single line should connect these responses to the central event.
04/19/23 SED AUB 74
4. Then each group should asks "What might happen if...?" about each of the first-order connections.
A double line should connect each second-order connection with the first-order connection that caused it.
As students work, remind them to thing of both positive and negative connections.

5. The diagram produced by the group then is shared with all the class and, if possible,
• A common futures wheel is drawn for the whole class.
• It is worth noting here that a futures wheel may be used to analyze any issue in school situations and in everyday situations.
