Instructions: Answer each question in complete sentences• Plants grow better in acidic soil. • Plants grow better in temperate environments. • Plants grow better when given love. • Plants grow better with horse fertilizer. • Plants grow better with patience. • Plants grow better in a pot instead of under ground.

• 1. Which of the statements above are testable and could be turned into an experiment?

• 2. What are these statements called in science?• Once you have finish your bell work, one person from each

group should go retrieve a ruler, piece of construction paper, and one bottle of glue.

Notes : Write in your journal, leave space in between to add notes additional notes later.

What is the Scientific Method? A step by step procedure that is used to determine if a testable hypothesis is valid. General Steps:1) Problem/Question ( based on observations around us)2) Research/Background Information3) Formulate a Testable Hypothesis4) Experimentation ( state control, variables: independent and

dependent)5) Collect Data ( quantitative; qualitative)- tables6) Chart and Communicate Results ( line, bar, or circle graphs)7) Form a valid conclusion

Group Activity One and Two Instructions

Activity One: On the construction paper, create two columns. Label one column : Hypothesis Label the second column: Not Hypothesis

Discuss with your desk-mates whether each statement on each card is a hypothesis or not. Glue each card into its appropriate column. Sit this to the side and let it dry.

Activity Two: Create/copy the following chart off the front board onto a lose leaf sheet of paper.Using the station cards at the lab tables ( six total), read the instructions for each card

then fill in the data table in which you have created. Turn in your Activity one poster and your individual data tables together as a group.

Lab Safety Video

• Take notes over the safety symbols while reviewing the short video. Your first quiz * will have questions pertaining to lab safety. Please listen carefully and ask questions if needed.

Examples Of an If/Then Hypothesis Statement

If the Vitruvian Man theory is accurate, then my arm span should equal my height.

If my arm span is equal to my height, then the Vitruvius theory is correct.

If my arm span is not equal to the length of my height, then the Vitruvius theory is inaccurate.

If the Vitruvius theory is accurate, then by forearm should be the same size as my foot.

If my forearm and foot are of equal sizes in length, then the Vitruvius theory must be correct.

Instructions/ Agenda: September 5-6, 2012

With your desk mates, complete the lab equipment functions worksheet. We will review this, for you will be both quizzed and tested over this information. After this, you will view the Do’s and Do Not’s of a Science Laboratory. Pay close attention and take notes if needed. Remember, your Unit One quiz is next Tuesday!

Agenda:1. Lab Equipment Worksheet- with your desk mates ( 10 min) 2. Notes: Scientific Method Continued ( 15 min)3. Lab Safety Video ( 25 min) ( student grade conferences)4. Closure: Course Reminders ( 5 min) *** times may vary according to students pacing*****

Notes: September 5th – 6th• Scientific Method Notes

• Scientific method—a systematic and orderly approach to solving a problem • Steps of the scientific method: • 1) State the problem or pose a question• 2) Form a hypothesis (an educated guess)• 3) Experiment• 4) Collect and interpret data• 5) Draw a conclusion• 6) Communicate the findings • The conclusion should support or reject the hypothesis

Notes, Continued• Variable—part of the experiment that changes

• Controls—parts of the experiment that stay the same; this set up of the experiment will not be tested on

• Independent variable—the factor that a scientist changes during an

experiment; also called the manipulated variable; This goes on the X axis

• Dependent variable—the factor that changes as a result of changes to the independent variable; also called the responding variable; This goes on the Y axis

• Constant: factors or conditions in an experiment that are kept the same in in all of the trials of the experiment. ( also called the controlled variable)

More Notes….

Three Types of Science Investigations Descriptive Investigation: Involve describing and/or quantifying parts of a natural system. Example – observing cells under a microscope and diagramming what is seen. • Has a research question, procedures, and conclusion • Used when little is known about the topic • No hypothesis or prediction • Key words: Observe, describe, list, identify

Comparative Investigation: Involve collecting data on collecting data on different populations/organisms, under different conditions (ex. Times of year, locations), to make a comparison. • Has a research question, possible hypothesis, procedures, and conclusion. • Can have independent/manipulated and dependent/response variables • No control / control group • Key words: Compare/contrast, similarity/difference, categorize

Some more notes….

Experimental Investigation: Involve a process in which a “fair test” is designed in which variables are actively manipulated, controlled, and measured in an effort to gather evidence to support or refute a causal relationship. Example- Testing the height of a ramp to determine how far a marble will roll. • All known variables have been identified • Has a research question, hypothesis, procedures, control, and conclusion • Has independent/manipulated and dependent/response variables • All factors can be held constant except the manipulated

YEAH….no more notes for the day…now pay close attention to the lab safety video you are about to view…and take notes ( if needed) over these safety rules…you also have the lab safety rules from your contract

Bell Work: Chemistry September 10, 2012

1. What is matter? How can it be defined?

2. What are the three common states of matter?

Notes ( chemistry) 9/10/12

Matter- anything that has mass and takes up space ( volume). The three most common forms of matter are solids, liquids, and gases. Properties of MatterChemical Properties- These are the properties that do change the chemical nature/composition of matter.

Physical Properties-Properties that do not change the chemical nature/composition of matter. The identity of the matter stays the same; descriptions of matter.

Notes ( chemistry)-09/10/12

Examples of physical properties are: color, smell, freezing point, boiling point, melting point, infra-red spectrum, attraction (paramagnetic) or repulsion (diamagnetic) to magnets, opacity, viscosity and density. There are many more examples. Note that measuring each of these properties will not alter the basic nature of the substance.

Examples of chemical properties are: heat of combustion, reactivity with water, PH, and electromotive force.
