Scientific Process
What is the first step in the Scientific Process ?
Observation.
Why is it important to have a control in an experiment?
To ensure that the changes made by the independent variables directly affected the dependent variables.
Is this Qualitative or Quantitative data ?
The sky is blue.
Qualitative
Find the Mean:
2,4,6,8,5
They add up to : 25
divide by 5
= 5
:)
What are the 4 states of Matter?
Solid, Liquid, Gas, Plasma :)
Why do we research before creating a hypothesis?
So we can have the information needed to make the best guess.
What is the dependent variable in the following experiment?
We are testing to see how different types of water affect plant growth.
How much the plant grows.
Is this Qualitative or Quantitative data?
There are 4 ducks ?
Quantitative
Find the Median:
2,4,6,8,5
5 its in the middle :)
What is a solute?
Something that is dissolved in a solution.
What is the last step in the scientific process?
Presentation.
What is the independent variable in the following experiment?
We are testing to see how different types of water affect plant growth
b. The type of water.
Is this Qualitative, Quantitative data or both ?
Ms. Tye is the super tall she is 178.5 cm.
both
Find the range
2,4,6,8,5
8 is the largest
2 is the smallest
8-2= 6
answer = 6
What is a solvent?
Something that dissolves other substances in a solution.
What are the first 4 steps of the scientific process in order?
Make an observation, ask a question, research, form a hypothesis.
Choose 2 control variables in the following experiment?
We are testing to see how different types of water affect plant growth.
The type of plant , how much water is given to each plant and how much sunlight is given to each plant.
Is this Qualitative, Quantitative data or both ?
Asian elephants are grey and weigh 4000 kg.
both
Fins the mode:
2,4,6,8,5,4

What is melting?
When a solid turns into a liquid ?
What are the last 3 step of the scientific process in order.
Analyze Data , Conclude and Present
In an experiment to see how the temperature of water affects the time it takes for sugar to dissolve, what is the dependent variable?
The time it takes for the sugar to dissolve.
Is this Qualitative, Quantitative data or both ?
The beaker is glowing red and it's temperature reading just hit 50 degrees Celsius.
both.
Get Ms.Tye if this happens in real life :)
Find the Median
2,4,6,8
4 and 6 are in the middle
4+6 = 10
10/2 = 5
What is evaporation ?
When a liquid turns into a gas.
