Scientific ObservationXX

The Scientific Process: 

The Scientific Process How to make a scientific observation

The scientific process: 

The scientific process There are four steps in the scientific process. 1) Observe something 2) Create a hypothesis A hypothesis is a possible explanation 3) Make predictions using The hypothesis 4) Test the prediction by experiments

How to make an observation: 

How to make an observation Notice things in the world around you What do you see, What do you hear What do you smell What do you feel

Make notes as you answer these questions: 

Make notes as you answer these questions Who are the subjects? What do they look like? What are they doing? Are the subjects interacting with each other? How? What is the environment like? Is the environment effecting behavior?

Observation: 

Observation Lets Practice… Do you see any animals in this picture? This is a moth, It’s camouflage causes it to look like a leaf

Observation: 

Observation To make an observation you must look closely and notice details. This looks like a leaf, look closer… Can you see the butterfly’s legs?

Questioning: 

Questioning Develop a question about what you see going on… Ask how, what, when, where, and why Be sure that the question can be answered with an experiment

Forming a hypothesis: 

Forming a hypothesis After you have asked the question give a possible answer Try to explain what was observed This is called forming a hypothesis

Forming a hypothesis: 

Forming a hypothesis Lets Practice… We see…yellow butterflies only on yellow flowers We form a hypothesis…. Butterflies go to flowers the same color as them

Making Predictions: 

Making Predictions The prediction is what you think will happen if the hypothesis is true. Our hypothesis is that butterflies go to flowers the same color as them A prediction could be… Red butterflies will land on red flowers Purple butterflies will land on purple flowers

Experimenting: 

Experimenting After the hypothesis is formed and the predictions are made they must be tested. An experiment is a way to test a hypothesis and see if what was predicted is correct.

Lets test our hypothesis: 

Lets test our hypothesis Hypothesis: butterflies will go to flowers the same color as them LETS EXPERMENT 1) Get flowers in a variety of colors, and butterflies in a variety of colors. 2) Put them together in a room 3) Keep track of what butterflies land on what flowers.

The results: 

The results

What did we learn?: 

What did we learn? We discovered that butterflies will land on any color flower. We will adjust our hypothesis and try again. It is important to remember that when a hypothesis is proven false it does not mean the experiment failed. Discoveries have still been made through the process of trial and error. Many great discoveries were found after years of trial and error. Home Page
