Introduction: The scientific method is something we use very often without being aware of it. This method

is a way of approaching problems in an organized way. Below are the basic steps of the scientific method:

1. Question: identify a problem and ask a question that aims to find

the answer.

2. Do Background Research/Observations: before you can start

solving the problem or finding answers you should see what else is out

there. This can be in the form of observations or research of

previously conducted experiments.

3. Construct a Hypothesis: This is an educated guess about the

answer to your question based on observations/research.

4. Test with an experiment: a procedure designed to test the

hypothesis

5. Collect and Analyze Results: collect, record, and analyze

quantitative (numerical) and qualitative (descriptive) data.

6. Draw conclusion: analysis of the experiment and discussion about whether or not the results support the

original hypothesis. Repeat, repeat, repeat-replicate you work to ensure the validity of your results.

7. Hypothesis was TRUE: report your results! Hypothesis was FALSE (or partially true): publish you

results anyway! This helps the scientific community. Then think again and try a new experiment

Background: Today we will conduct an experiment and make detailed observations. The steps of the scientific

method will guide our work. This investigation will test different qualities of milk to see their reaction when

food coloring and dish shop are added. We will observe and record the different reactions of the different milk

types

Materials:

Petri dishes

dish soap

whole milk

Food coloring

eye dropper

2% milk

1% milk

Scientific Method:

1. Ask a question:

_________________________________________________________________________________

2. Research/Preliminary Observations

a. Name one thing milk, food coloring, and dish soap have in common:____________________________

b. Give you best definition of density

Experimental Design
