1. Laboratory Report Format You will have the option of either handwriting or typing your lab reports. You will be graded on the following: 1. Accuracy of results 2. Written conclusion 3. Format-See slide 5 4. Title page-see slide 4 Each lab is worth 40 pts. A missing lab report will result in a grade of “U” in work habits.

2. 7 step format All labs will follow a 7 step format. 1.Purpose: State Science standard & Objective are listed in one or two sentences. 2.Background: All related information concerning the standard/objective. This includes all vocabulary, formulas, lab tools and procedures necessary to complete the lab. 3.Materials: A list of all lab tools used in the lab. 4.Hypothesis: A prediction of what you think will happen. 5.Procedure: Numbered sentences explaining what was done for each step in the lab. 6.Results: A table or chart placed on a SEPARATE PAGE with numerical data from measurements made and recorded during the lab. 7.Conclusion: A brief written summary or answers to questions of why your hypothesis was right or wrong and what you learned.

3. Typing/Writing Format Margins: should be 1” all the way around, double spaced. If you do not know how to set your margins I can show you. Font: Palatino, Geneva, or Times. Size: 10, 11, or 12 pt.

4. Format Examples Purpose: The purpose of this lab is to measure and record the density of various solids and liquids. This lab exercise is designed to assist students in the mastery of state science standards 8a, 8b, and 8d. Background: Density is a very important measurement in science. It is useful to determine the identity of various forms of matter. The density of a substance is acquired by Each of the 7 section titles is underlined in bold print. Left margin is justified at 1”, no indentation. Double space between each line.

5. Density Lab Name Date Period Title Page 16-18 pt. font 12 pt. font Title should be 1/3 from Top of page Name, date, period should Be 1/3 from bottom of page.

6. Purpose & Standard: The purpose of this lab was to accurately measure the density of regular and irregular solid objects to determine if they were buoyant or not. Data was obtained using measurements of mass and volume from various lab techniques. Standard 8b: Students will know how to calculate the density of substances from measurements of mass and volume. (copy this exactly) Background: Density is a very important measurement in science. It is useful to determine the identity of various forms of matter. The density of a substance is acquired by dividing the mass of that substance by its volume. The formula to calculate density is D=m/v. The mass of an object is the amount of matter it contains. Mass is measured in grams with a beam balance.

8. Paragraph 2 (background Paragraph 3 (background) Materials: Balance, graduated cylinder, beaker, pipet, overflow can, red bolt, plastic square, rubber stopper, cork stopper, metal cylinder, golf ball, tile plate, wood cylinder, metal square, rock sample.

9. Hypothesis: Predict whether each item will sink or float. Red bolt ________ Plastic square ________ Rubber stopper ________ Cork stopper ________ Tile Plate ________ Rock Sample ________ Golf Ball ________ Metal Cylinder ________ Wood Cylinder ________ Metal Square ________

10. Procedure: 1.Red Bolt & Marble: We filled the graduated cylinder to exactly 50 mL. We used the dropper to make sure we were accurate. Placing the red bolt in the graduated cylinder we waited until the water level increased.
