Transcript of Copy of General Science, measurement and scientific method

General Science and Graphing
What is a scientist?
1. Draw what you think a scientist looks like in your science notebook.
2. Write on your drawing words that describe what a scientist does.
3. Could you be a scientist? Explain
4. Color your drawing.

Is this what you think a scientist does?
Did you say:
That a scientist uses skills like observing and comparing, classifying data, modeling and simulating, measuring, analyzing data, communicating results, making predictions etc.
Describe what a scientist does and the tools he / she might use
TSC - Lets Practice
Topic Sentence
Supporting sentences
Conclusion
Describe what a scientist does and the tools he/she might use. Write using the TSC format.

Question of the Day
Question of the Day
Explain the difference between mass, volume, length and what tools are used to measure each one (TSC Paragraph)
Scientific Method
What is the scientific method? It is the method used for scientists to organize and solve problems.
Step 1 - Develop a question
Step 2 Research your problem
Step 3 Develop a hypothesis
Step 4 Experiment
Step 5 Analyze and record your data
Step 6 Conclusion

Question of the Day -
Why is it important to follow the rules and procedures during a science lab? (TSC paragraph)
Mass
Mass measures the amount of matter in an object
Tool used: Balance
Unit: Gram, kilogram
Weight measures the pull of gravity on an object
Tool used: scale
Unit pounds and newtons
Volume
Volume is the amount of space an object takes up
Tools used: graduated cylinder, formulas ex. l x h x w (for regular solids) and water displacement for irregular objects
Unit; liters, milliliter
Length or Distance
Distance is a measurement of something's length, width, or height
Tools used: meter stick, odometers in cars, rulers
Unit: Meter, kilometer
hand out scientific measures
Why is it important for units to be standardized when measuring? (TSC)
Question
This is where we develop the question or problem we are going to investigate or study
Research
Consider all data that might help answer the question or problem.

Hypothesis
Use the information in your research to form a possible answer to your question or problem.
A lot of times a well written hypothesis will have an if then statement. For example If I put fertilizer on the flower then the flower will grow taller..
Observation Sheets and activities
Inferences -
Data -
Qualitative Observations -
Quantitative Observations -
Experiment / Test
This is where you test your hypothesis.

You must have a step by step procedure to follow. Your procedure must be very specific.

Must have an Independent variable - A part of the experiment that can vary or change. You have control over this part of the experiment. For example - The height you drop a ball

Dependent Variable - Depends on the independent variable. For example - how high the ball bounces after you drop it from different heights
Analyze or Record Data
Record the results of your experiment.

Create tables and graphs with data collected from the experiment.
Write down a description of the conditions you thought would and did happen during the experiment. Write down your feelings and observations you made. You also need to explain the facts and figures from the tables and graphs
Conclusion
Examine your written data and decide if your hypotheses was correct and why. What surprised you about your data? What changes would you make if you did the experiment again?
Fun scientific method song
Now it is your turn to show what you know, - make a mini book, rap or song or
poster.
Hand Warmer lab
The Scientific method
My hypothesis was correct because .....
Let's practice a TSC
Question of the Day
What is the difference between a qualitative and quantitative observation? Use examples in your paragraph. (TSC)
Question of the Day
What is the difference between an observation and an inference? Include examples in your paragraph. (TSC)
Question of the Day
Describe the steps of the scientific method. (TSC)
Question of the Day
Every experiment has dependent and independent variables. Describe a dependent and independent variable and why you need to have them for a good experiment. use examples in your reflection
