PRETTY


Marika's Blog for 9/29/09

This week, I learned a lot about the steps of a full experiment. The first step is to observe, where you take in every little detail that you can see. After observing, you need to create a hypothesis. The hypothesis can be wrong, but the prediction cannot. After you make a hypothesis, you think up of an experiment to test. That is the experimentation step. After this experiment, you prove if your hypothesis is right or wrong. For example, if you are a doctor and you get a patient one day, your observations can be that this patient is sneezing, coughing,have a runny nose, and be sweating like he/she is hot. Then, you could make a hypothesis : this person might have a cold. You could test this by checking the inside of this patient's ear, checking the patient's mouth, and the breathing and heart rate. If you see an infection in the ear, or swelling in the mouth, you could or should be able to tell if your hypothesis was right or wrong. Then, you could make another hypothesis, or possibly a prediction. If you make a hypothesis, you could test again and find out more about the sickness the patient has. In class, we did this by having one student pretend like she was sick, like coughing, etc. I learned many things this week.
