SCIENTIFIC METHOD
Read each slide.
Look carefully at each picture.
Answer each question.
All scientists follow rules when conducting an experiment.
These rules are called the
SCIENTIFIC METHOD.
Scientists follow
these rules so
other scientists
can perform
the same
experiments.
Scientists perform each experiment at least 3 times.
They want to
make sure that
each experiment
really works.
The first thing you need is a
PROBLEM.
Next you make a guess about what will happen during your
experiment.
This is your
Next you do the experiment to find out what happens.
1 2 3
Remember that you must do each experiment at least three
times.
Now you have the results of your experiments.
Results are called
DATA.
Data can be shown in many different ways.
This is a bar graph.
This is a pie graph.
This is a line graph.
Sometimes scientists put their data together into a report.
After looking at the results you decide on a
CONCLUSION.
When you do an experiment use your 5 senses to
make careful observations.
Remember to record your observations and data
into a:
graph or
a chart..or
a table
or your journal.
It is important to record your results for others to see.
You must use scientific words and measurement
when your write about
your results.
Scientists don’t say,
“It is cold.”
“It is cold,”
is a personal opinion.
You might say, “It is 32 degrees Fahrenheit.
Scientists say, “It is zero degrees Celsius.
A scientist
would never
say,
“The flower
is tall.”
A scientistwould say, “It is 30 centimetersfrom theground to the petals.”
Scientists measure
everything!
They measure the volume of liquids in liters.
They measure the mass of an object in grams.
They measure the length of an object in meters.
A meter can be broken down into
smaller units to measure smallerthings.
CENT means 100.There are 100 cents in 1 dollar.
There are 100 centimeters
in 1 meter.
You can buy soda in liter bottles.
The mass of an object is measured in grams.
This MARS Ice Cream bar weighs 50 grams or has a
mass of 50 grams.
This puppy had a weight of 500 grams or a mass of 500 grams
when he was born.
We ask, “How much does it weigh?”
A scientist asks, “What is the mass of the object?”
Meters, grams and liters are all ways to measure using the
METRIC system.
Scientists always use the
METRIC system.
