This step is when you observe and ask...
Step (1) Question or observation
100
How many mls in a L?
1000 mls in = 1 L
100
Use this to Measure DISTANCE
Ruler, Tape measure, Meter Stick
100
Types of Data: numbers, times, distances.
(qualitative. OR quantitative)
QuaNtitative Data
100
How do you calculate the AVERAGE?
At ALL together and DIVIDE by the number.
A+B+C / 3= average
200
This step you discuss your data, hypothesis, errors and mistakes.
Step (6) Conclusion and sharing
200
What unit measure TEMPERATURE?
Celsius degrees 34 Co
200
What is this called? Used to measure mass
Triple Beam Balance
200
What is it called when you look at data and graphs to see relationships.
(ie. The biggest / smallest, fastest / slowest, difference between)
Analysis / Analyze Data.
200
Why do we SHARE results?
So scientists can se our results, try the experiments and test our theories.
300
Putting collected data into tables and a graph happens in this step.
Step (5) Results
300
The amount of SPACE inside or AMOUNT something can hold.
Volume
300
A Graduated Cyclinder is used to measure _____ in ___ units?
Volume (of liquids) in mls.
300
Control Variables
Everything else is KEPT the SAME.
300
In an experiment, how many trials should we do? WHY?
Try to do about 4-5 trials. This reduces errors and we can calculate an average.
400
In this step you list the materials needed and write a step-by-step procedure.
Step (4) Experiment. (materials & procedures)
400
Amount of matter in an object.
Mass
400
Measures amount of heat
Thermometer
400
Dependent Variable
What is MEASURED?
400
Scientist given credit for discovering GRAVITY
Newton
500
YOUR educated guess. (If.......then......)
Step (3) Hypothesis
500
Write the difference between VOLUME and MASS.
Volume is the amount of SPACE and object takes, the MASS is how heavy or light it is.
500
Convert
7954m = ________km
437ml = ________L
7.954 km
0.437 L
500
Independent Variable
What is CHANGED?
500
Do you know what INFERENCE means? (To make a inference is to...)
make a guess.
