1 Mi Primo es un frutas murciélagogo Pus! It’s not for breakfast anymore! Colors that rhyme with recalcitrant More Strawberry Squirrels please! YUM! Mr. Laneeous 100 100 100 100 100 200 200 200 200 200 300 300 300 300 300 400 400 400 400 400 500 500 500 500 500

2 Make an objective statement. What makes it objective?

3 An objective statement is a statement of fact.

4 Make one of each…please 
Explain the difference between a qualitative and a quantitative observation. Make one of each…please 

5 Qualitative = descriptive Quantitative = numerical

6 What is science?

7 A method of learning about the natural world, as well as to the knowledge gained through that process.

8 What is a hypothesis?

9 A Hypothesis is a prediction or possible explanation for observations relating to a scientific question.

10 What is a theory?

11 A theory is: - an explanation for observations or events
A theory is: - an explanation for observations or events. - It is based upon proven hypotheses. -It is critical that a theory is verified multiple times by detached groups of researchers (this means it is WELL-TESTED).

12 -Explain what a manipulated variable is and give an example
-Explain what a manipulated variable is and give an example. -What is another name for a manipulated variable?

13 The manipulated variable is also called the independent variable
The manipulated variable is also called the independent variable. It is the variable that the scientist changes. Example: the color of the light in our virtual lab.

14 -Explain what a responding variable is and give an example
-Explain what a responding variable is and give an example. -What is another name for a responding variable?

15 The responding variable changes due to the manipulated variable, and this is what the scientist measures. Example: the height of the plants in our virtual lab.

16 If you performed an experiment measuring the wet strength of several brands of paper towels, what could two controlled variables be?

17 The liquid used The weights placed on the towels How the weights are placed

18 When doing a controlled experiment, why don’t we change more than one manipulated variable at a time?

19 You wouldn’t know which variable was responsible for your results.

20 You are measuring the affect of the sun on various color fabrics
You are measuring the affect of the sun on various color fabrics. What is one possible responding variable?

21 -Fading over time -Temperature -Amount of light reflected

22 What are the steps of the scientific method?

23 -Develop a hypothesis (If/Then). -Experimenting and testing.
The Scientific Method -Ask a question. -Develop a hypothesis (If/Then). -Experimenting and testing. -Collect and organize data. -Analyze data. -Draw conclusions (substantiate or refute). -Retest.

24 What must be true of a VALID hypothesis
What must be true of a VALID hypothesis? Give an example of a valid one and one that is not valid.

25 It must be testable! Valid: If three objects of differing masses are dropped from the same height, they will all hit the ground at the same time. Not Valid: If a hungry dragon has the choice between a hobbit, a mermaid, and Spiderman, it will eat the hobbit.

26 If you test your hypothesis and it is not substantiated…have you failed? Explain!

27 NO!!!!! You still learned something.

28 Give an example of experimental data.

29 -plant growth in cm -mL of rainwater collected -speed of a test vehicle

30 Differentiate between mass and weight.

31 Mass is the measure of the amount of matter that composes an object
Mass is the measure of the amount of matter that composes an object. Weight is the effect of gravity on an object’s mass.

32 What does a mathematical model do?

33 Uses equations to make PREDICTIONS
Uses equations to make PREDICTIONS.…if you have certain data, you can “plug it into” the model.

34 What scientific measurement system is based upon the metric system?

35 The SI or International System

36 What is the purpose of using physical models?

37 They are used to represent objects or systems that are not otherwise practical to study.

38 Why are models used in science?

39 Some things are not easy to study any other way
Some things are not easy to study any other way. A few reasons for that…they may be too large, too small, or too dangerous.

40 What does a conceptual model show?

41 It helps to diagram important interrelationships among processes and systems.

42 Which laboratory instrument consists of a tube, lenses, a stage, and a light source?

43 Compound Microscope

44 What are three types of models and what are their limitations?

45 Physical Mathematical Conceptual They are not the actual “thing” being studied.

46 What is THE most important thing in the laboratory?

47 SAFETY!!!!!

48 Differentiate between a scientific theory and a scientific law?

49 Both tie together related observations, ideas, and supported hypotheses, and both allow for predictions to be made. A law states what will happen under specific conditions; a theory explains why it happens.

50 What is the largest living reptile?

51 The Saltwater Crocodile Crocodylus porosus
