hypothesis formulation

2. Daily Task:Formulate
hypothesis from a given
situation.

3. REVIEW!
What are the steps in scientific method?

4. ENGAGE!
Actual demonstration

5. Demonstration 1. Get a glass of water.
Say that this represents a body of water.
Place a paper boat inside the glass with
water. Let the students observe the
paper boat (how much of it is
submerged

6. 2. Add 2 pieces of paper clips into the
boat. Let the students observe what
happens to the boat.
 Ask the students:
*How many paper clips are needed to
sink the boat?
Start the hypothesis in thos manner/format:
“If I add X clips, then the boat will sink.” (The
students may guess different number of clips.)

7. 3. Ask for the basis of their guess:
Why that number?

8. EXPLORE!!
Essential Question: How is
hypothesis formulated?
SEE ATTACHED TASK CARD

9. Arrange the scrambled letters to form the 3
major types of hypothesis.Do this by group
LUNL
ALSCAU
EVITALTANREE

10. Students will present their output
Lecturette:
What is hypothesis?
a testable statement about the relationship
between two or more variables or a
proposed explanation for some observed
phenomenon.
Educated guess/tentative answer to the
problem

11. What are the 3 major types of hypothesis?

12. 3.Causal Hypothesis

13. "Plant growth rate is unaffected by
the presence of fertilizer in the soil."
"Plant growth rate is faster with the
presence of fertilizer in the soil."
What Type of Hypothesis I Am!!!
Raising gas prices causes an increase in the
number of people who carpool to work.

14. ELABORATE

15. Activity Performance and Output will
serve as evaluation.

What are different types of
variables?
