Question/Problem

Problem: Know what is wrong with

something, ask questions about it. What

your hoping to achieve, something youcan measure.

Question: Ask a question aboutsomething you want to observe.

Inference: An inference is a conclusion to

your observation. From what u observed

you could infer what the problem really is.Hypothesis: You translate your inference

into an educated guess.

Evaluation

Evaluation: Things that could be done

next time to improve yourexperiment.

Variables: The thing or things that

change after or during an experiment.

Bias

Bias: Is something that will make your

experiment unfair.


12/25

Theory

Theory: A theory in science is an explanatory

statement that's been repeat key confirmed

through experimental testing.

Law

Law: The law is a statement

based on repeated experimental

observations that describes

some aspect.

Animal Camouflage

Problem:

Hypothesis:

Materials:

-Scissors-1 a4 page of green paper-1 a4 page of green paper cut in 1 inch squares

-1 a4 page of brown paper cut in 1 inch squares

How does camouflage effect vision?

People would choose contrasting colour over the matching

colour.


15/25

Method:

Conclusion:

1. Cut one page of green and brown paper into one

inch squares.2. Arrange the squares onto a piece of green paper.3. Give subjects 5 seconds to grab as many pieces of

paper as they can. Limit subjects to picking up one

piece at a time.4. Record how many green pieces and brown subject

picks up.5. Tally the results.

Lots of people picked the brown pieces of paper and notmany people picked the brown piece of paper.

Evaluation:We could try the experiment with more people and we

could try different colours.

Eggsperiment

Problem:

Observation:

Hypothesis:

How can I tell the difference between a cooked egg

and a raw egg?

We tried to shaking the eggs sideways which kind of

helped, we tried putting the eggs in the water but that didn't

really make a difference. We are pretty sure we could tell

which was the boiled by trying the shaking method.

Cooked egg will spin very well, while the raw will not

spin as well.


17/25

Materials:

Method:

Conclusion:

Evaluation:

-2 raw eggs

-1 boiled egg

1. Spin each of the eggs on a hard surface, observe

and record the results.

We figured out that because only 1 was cooked and

only 1 was spinning.

We could repeat the experiment only mark the eggs

beforehand or use more raw eggs.

19/25

Method:

Conclusion:

Theory:

1. Pick up one balloon and stand facing your friend.

2. Toss the balloon.

3. After a successful catch, both of you take a step

backwards.4. After your friend tosses the balloon back to you, each

of you takes another step backwards.

5. Continue this process until the balloon breaks.6. See how far apart you can get until the balloon breaks.

Excerpt From: Robinson, Tom. The Everything Kids' Science

Experiments Book. F+W Publications, Inc., 2001. iBooks.

Variables:Different amounts of water in the ballon and different

sizes of balloons.

When we were 8 meters apart the balloon seemed to pop

the fastest and the easiest and our hypothesis was

proven right.

The balloon kept on

popping when we were

further apart for each otherand the higher we threw it,

it would pop in mid-air.

Cowsperiment

Problem:

Hypothesis:

Materials:

If you put garlic in cows feed how much

methane will it produce?

It will help just a little bit but the cows might still

produce methane.

5 CowsA lot of garlicA machine that can see how much cows fart after

eating garlic


21/25

Method:

Variables:

1. Get all 5 cows into a large tent.2. Feed each cow 25 pounds once a day, mix the

feed with garlic, for 2 weeks.3. Take air samples from the large tent every 5 times

a day.

4. Test the air samples for methane every 3 days.5. Collect data.

Use a different kind of garlic.

Deterg-periment

Problem:

Materials:

Hypothesis:

Which laundry detergent works best?

I think ______________ might work best.

5 different kinds of laundry

detergentMudKetch upBBQ sauceGrass20 different white fabricsA container (that won't leak)


23/25

Method:

1. Add a stain of mud onto 5 pieces of the fabric and label

the fabrics as "mud"2. Put each of the fabric in separate containers.3. Add water into the container.4. Add ONE kind of detergent into each of the 5

containers.5. Shake the containers for 10 minutes.6. Take out the fabrics and rate from 1-5 (1 is the worst, 2is slightly dark satin remains, 3 is faint stain remains, 4 is

very faint stain remains but mostly no stain and 5 is the

best) based on how well each of the detergents removed

the stain7. Repeat the steps from 1 to 6, but use different types of

ingredients to make the stains and different pieces of

fabric.8. Add up the rating score you gave each laundry

detergent and the detergent with the highest rating score

total is what works best.
