Science and scientists
Science and Scientists

Science is a process of gathering knowledge about the natural world.

Science starts with a question and uses several methods to find the answer.

Scientific method1
Scientific Method

Scientific methods are the ways in which scientists answer questions and solve problems.

Scientist may use all the steps or some of the steps in an investigation.

Scientific method3
Scientific Method

Scientist tend to ask a question after making observations.

An observation is any use of the senses to gather information. Observation can be made throughout the experiment.

Fall 2005, Pflugerville ISD


Scientific method4
Scientific Method

When scientist what to investigate a question, they form a hypothesis.

Hypothesis is a possible explanation or answer to a question- educated guess.

Fall 2005, Pflugerville ISD

Scientific method5
Scientific Method

After a hypothesis is form, scientist must test their hypothesis.

Dataare any pieces of information gathered through experimentation.

Data can tell scientist if the hypothesis is valid or not.

Fall 2005, Pflugerville ISD


Scientific method6
Scientific Method

Once data has been collected, scientist must analyze their data.

Analyzing results help scientist construct reasonable explanations based on evidence they collected.

Fall 2005, Pflugerville ISD


Scientific method7
Scientific Method

Do the results support the hypothesis? Scientists study the results to see if their hypothesis is right or wrong.

They may repeat the investigation or ask new questions and form a new hypothesis.

Fall 2005, Pflugerville ISD


Scientific method8
Scientific Method

Scientist share their results by writing reports in journals, giving lectures or by way of the internet.

1. What are some of the steps in the scientific method?

Fall 2005, Pflugerville ISD


Answer4
Answer

Ask a question

Make observations

Form a hypothesis

Test hypothesis

Collect Data

Analyze Data

2. Why is a hypothesis sometimes called an educated guess?

Fall 2005, Pflugerville ISD


Answer5
Answer

A hypothesis is a possible solution based on previous knowledge, so it is an educated guess.

3. What options does a scientist have if the results of an experiment do not support a hypothesis?

Fall 2005, Pflugerville ISD


Answer6
Answer

A scientist could repeat the investigation to check for errors or could ask new questions and form a new hypothesis.

Scientific models1
Scientific Models

Modelsare representations of objects or systems.

Models can be used for:

  • Understanding something

  • Predicting

  • Picturing things in your mind

  • Explain scientific theories
