Question/Problem

The problem is alsocalled the aim. It iswhat you are hoping

to achieve.


4/29

Inference/Hypothesis

A hypothesis is a testable explanationfor the details you observed or an

educated guess.


5/29

Materials

The materials are what you need toconduct the experiment. A very

good materials list is very specic.


6/29

Method/Experiment

The experiment is the test you conduct tosee whether your hypothesis was right or

not.


7/29

Observations

The observations are what you seeafter the experiment.

Conclusion

This is the ending statement showing what you found out during your

experiment.

Theory

A theory is anexplanatory statementthat has been provedthroughout multiple

tests.

Conclusion: Camouage affects vision in a

way that makes certain thingsdisappear on certainbackgrounds. Below is a graphshowing our results.

Evaluation: We could test more people. We

could try different paper colours. Wecould try older people, youngerpeople, teachers, students andparents.

EGGSPERIMENT

Problem:How can I tell the differencebetween a raw egg or a cookedegg?

Hypothesis: A cooked egg will spin, a raw eggwill not.

Materials:

Two raw eggs, one hardboiledegg, a hard surface.

Method:Spin each if the eggs on a hardsurface. Observe and record theresults.

Observations:

Snifng it we couldn't detect adifference. Shaking it we could hear asloshing sound in two eggs. Puttingthem in water all of them sank.


17/29

Conclusion:

The cooked egg spins betterthan the raw egg because theother two spun poorly.

Evaluation: We could try different surfaces,

different eggs and a soft boiledegg.

Observations: We found that one of the eggs

span faster and was even whilespinning. The other two spanslowly and shakily.

SURFACE TENSION EXPERIMENT

Problem:

Can a paper clip affect thesurface of different liquids?

Materials: Water, paper clip, oil, washing up

liquid, bowl

Hypothesis: I think the paperclip will oat better ondifferent liquids than on straight water.

Method: First put the liquids you are going to test intheir own cup. Next take a paperclip andslowly and carefully put a paperclip on thesurface of the water. Observe and write downresults.

Observations:

We found that you could place a maximum of16 paperclips on the surface of the water.


19/29

Observations: We found that all the other solutions

apart from water didn't have surfacetension.

Conclusion:

We found that only the water hadsurface tension because of it'smolecules are very specic.

Evaluation:

We could have tried non Newtonianuids like honey. We could have trieduids like vinegar or salt water.

Water 100% water and oil 0%water oil and detergent 0% oil 0%

DETERGENT EXPERIMENT

Problem:

What clothing detergent worksbest?

Hypothesis:

BLANKNESS

Materials: Five leading clothingdetergents, 25 10 by 10cm squares, grass, coffee,tomato sauce, barbecuesauce, cola, hot water vecontainers.


23/29

Group the swatches and see what detergentgave the best result for each stain. Rank thedetergents as 1 still very stained, 2 slightlydark stain remains, 3 faint stain remains or 4no stain remains. Then total each detergentspoints and then you will have the winner.

Method: First take ve of the cloth swatchesand stain them with coffee. Next stainve with barbecue sauce. Now stain

ve with tomato sauce. Now stain vewith cola. Lastly stain the veremaining swatches with grass.

Now take the fe containers and put about 1/

4 of a cup of one washing powder in eachcontainer with three cups of hot water. Eachcontainer must have a differently stainedswatch of cloth in them.

Now shake each for ve minutes and let themrest for another ten minutes. Do this for eachwashing powder. Now look and see whichdetergent did the best at removing all thestains but take into account wether the fabricfaded or how soft they are.

Problem/Question How much baking soda/ vinegar is needed forit to make enough pressure to make a lmcanister rocket perfectly y. Observation Based on a baking soda volcano the pressurewill make it go up since it's going to throw thecap down. Hypothesis It would explode or y depending on thepressure level caused by the reaction of thebaking soda and vinegar. Materials @a tin canister (height of 8cm length 5.5cmcircular) @baking soda (sodium bicarbonate) @vinegar (any kind will work, but whitevinegar is easiest to clean up) @an ice cream stick or teaspoon

@a plate, saucer, tray or similar (optional)

@eye protection (glasses, sun glasses orsafety goggles) @an adult

THE BAKING SODA ROCKET


27/29

Method/Experiment First, put on eye protection. Second, practiceputting the cap on and of. Third, put about oneand a half teaspoons of baking soda and 5

millilitres of vinegar into the balloon ( this is avariable change the amounts from 5 to 5 millilitresexample 5,10,15 and or add another one and ahalf tea spoons ). Fourth, ll the canister with thebaking soda and then put the balloon lled with

vinegar (use a teaspoon to put the baking soda).Fifth, instantly put the cap on and turn it upsidedown and then shake it once and take cover. Observations Vinegar is like the fuel and the baking soda wasthe oxidiser. More vinegar makes a better launch.More vinegar causes lots of goo. The tin canisterwent about 6 meters high. Conclusion It ends up that an almost lled ballon and 3spoons of baking soda on and 8cm by 5.5cmcircular tin canister ies about 6 meters high. Evaluation

There are some things that we could due to makeit better like lm canister instead of tin, stabiliserns, wings so it can glide better and not break andstronger vinegar.
