Theory

Is an explanatory statement that's beenrepeatedly confirmed though experimental

testing

Law 

A law generalizes a body of observations. Atthe time it is made, no exceptions have beenfound to a law. Scientific laws explain things,

but they do not describe them. One way to tella law and a theory apart is to ask if thedescription gives you a means to explain'why'.http://chemistry.about.com/od/  chemistry101/a/lawtheory.htm

Eggsperiment 

Observation

Materials

Problem

How to tell the difference with a cooked andraw egg

Hypothesis

One egg is cooked. They all feel the same.Finally we tried shaking the eggs. Biassed onwhat we think we know what the cooked eggis.

A cooked egg spins badly and a raw eggspins very well

2 raw eggs 1 cooked egg Hard surface

Method

Evaluation

Spin each of the eggs on a hardsurface observe and record the results

Conclusion 

It probably was the second egg because theegg was spinning very well. Because the othertwo did not spin well.

We should have more eggs one softone hard one raw

Observations

One egg spines very quickly. There is a veryslow egg also.

Materials

Does the size of an object affect the buoyancyof that object 

The smaller the paper clip will take lessspace in the bowl and float better 

Water bowl paper clips one small one big

Fill the bowl with water. Take both paperclips and carefully put them in the watersrepeat the experiment 

The paper clips float on water. Theymust be made of aluminium

Observations

Conclusion

The big paper clips did not float.The small ones floated for aminute then sank

My hypothesis was right the big ones did notfloat. This was a wet experiment for sure. Ican't wait for the next one. 

Evaluation

We could put towels around the bowl to notmake a mess. We could have something to

pick up the paper clips to not make them fall.

Methane 

Materials 

Does adding garlic in cows food

affect the amount of methane theyproduce?

Hypothesis They will fart cleaner airbecause of the Garlic in theirdigestion system.

Monitoring machine

Thermal cameraGarlic Cow food

Method Inflate the tube put the cow in. Connect the

machine to the tube. Set up the thermalcamera facing the mouth and the butt. Do thesame thing with three more cows. Feed twocows with normal food and with the other twoadd Garlic to their food. Monitor your results

and repeat the experiment 3 times for threeweeks

Method

Get five pieces of white fabric and labelthem with like A,B,C,D,E. Use the grass

rub it to make a green mark(top rightcorner). Pour the BBQ sauce(top leftcorner),ketchup( bottom right corner)and coffee( bottom left corner) on thefabric. Let it dry. Stain all of them. Put

one of the pieces of fabric in thewashing machine put some of one of thewashing detergents in the washingmachine. Wait till it's done. Do the samewith different detergents. To know which

one is the best. The one that looks thecleanest is the winner.
