Question/Problem

Explain

A problem is the thing that you mostly

worry about and sometimes you don't

know what the answer might be.

BRAIN POP

To answer a question it

must be something

that you can measure.

Inference/Hypothesis

Explain

An inference is a guess, it can be an

educational guess or a non-educational

guess.

A hypothesis is an educational guess.

BRAIN POP

It should be

constructed in the way

to help you answer

your problem.

Materials

Explain

Materials are the things that you

need for your experiment.


6/19

Method/Experiment

Explain

An experiment is a test from your

hypothesis.

BRAIN POP

Method means the steps

for your experiment.


7/19

Observations

Explain

Observation: You check at your

experiment if it is going good or bad.

BRAIN POP


8/19

Conclusion

Explain

Result in your experiment.

9/19

Evaluation

Explain

It means you have to fix something.


10/19

Variables

Explain

Something you have to

change.


11/19

Bias

Explain

If you have a bias on your

experiment it means, you're

not having a fair test.


12/19

Theory

Explain

Theory is like a result but it

has to be the same results over

and over again.


13/19

Law

A law generalizes a body of observations.

Animal Camouflage

Problem: How does camouflage effect vision?

Hypothesis: People would choose the contrasting colour overthe matching colour.

Materials: -1 a4 paper of green paper-I a4 page of green paper cut in 1inch squares-Scissors-I a4 page of brown paper cut in 1inch squares

Method:

1. Cut 1 page of green and 1 page of brown paper into oneinch squares.2. Arrange the squares onto a piece of green paper.3. Give subjects 5 seconds to grab as many pieces of paperas they can. Limit to subjects to picking up one piece at a

time.4. Record how many green pieces and how many brownpieces subject picks up.5. Tally the results.


15/19

Conclusion:In the end most people picked up the contrasting colour. Hereare the results when we tested 9 people:

Evaluation:If we did the experiment again I think we could improve it bytesting more people and also choosing colours that are closertogether.

Water Balloon Toss

Problem:

Will the balloon break in longer distances or shorter

distances?

Hypothesis:The longer the distance between us the faster theballoon will break.

Materials:Several filled water balloonsA friend who doesn't mind getting wet

Method:Pick up one balloon and stand facing your friend.

Toss the balloonAfter a successful catch, both of you take a step

backwards.After your friend tosses the balloon back to you,

each of you takes another step backward.

Continue this process until the balloon breaks.See how far apart you can get without breaking the

balloon.

Observations:We started by 3 meters away for each other then

tried throwing the ball 4 times around but it didn't

pop but it only popped when it hit something hardwhich doesn't count. When we were 8 meters apart

the balloon popped much faster and easier. We

noticed that The balloon seems to pop whenever we

were further apart. The balloon seems to pop

whenever it's in mid air. We noticed that thetexture of the balloons affected when it popped.

We realised that each balloon has a different

texture. Each colour has a different way of popping.

The higher we throw, the easier it breaks. On our

last balloon it slid onto the ground and because of

friction the balloon popped.

Conclusion:When we were 8 meters apart the balloon seemed

to pop the fastest and the easiest and our

hypothesis has proven right.

Theory:The balloon kept on popping when we were further

apart for each other and the higher we throw it, it

would pop in the mid - air.
