OBJ: Given outline and abstract form SWBAT write a handwritten college-level lab report on light, prisms and filters with 70% accuracy.

DN: Review Lab Report including procedures, conclusion questions.

ACT: Complete Light Prism and Filters Lab.

HW: Complete Lab (including college-style report, Conclusion Questions and Abstract Form, due end of period or Monday); SVQ2 Quiz (erosion-magnetic force), week of Dec 8; Light Exam, Dec 8.

LAB REPORTTitle : State a title for lab.

Problem: How does light behave as it travels through a prism and/or filters?

Hypothesis: As white light travels through:1] a prism, I observe _______ ?2] a single red filter, I observe _______ ?3] filters of one color (blue), I observe _______?4] filters of different colors (red, blue), I observe ______?

Materials: State equipment used during this lab.

PROCEDURES• Experiment 1, Part A: Shine white light

(flashlight) through a prism so that the light shines onto a sheet of paper. Record my observations (look at white screen).

FLASHLIGHTPRISM

SCREEN

PROCEDURES• Experiment 1, Part B: Place a red filter

between flashlight and prism. Record my observations.

RED

PROCEDURESExperiment 2: Shine white light (flashlight)

onto white screen. Add same color filters one at a time. Record my observations.

SAME COLOR FILTERS

PROCEDURES• Experiment 3: Shine white light through a

prism onto the white screen. Place red filter between prism and screen.Record my observations.

RED

PROCEDURES• Experiment 4: Shine white light through a

red filter. Place blue filter between red filter and the screen. Record my observations.

RED BLUE

DATA / RESULTSFor each experiment, I will do the following:

1] Describe what I observe on the white screen.

2] Using scientific terms (such as absorbed, transmitted, refracted), I will explain why this is happening. I will be specific.

REMEMBERFilter: absorbs (blocks) all colors except for the color of the filter

Black: absence of light

CONCLUSION QUESTIONSExperiment 1, Part A: 1. Name the colors seen on a screen when white light passes

through a prism.Experiment 1, Part B:2. What does a filter do to white light that passes through it?Experiment 2: 3. What happens to the light on the screen as you add filters of

the same color?Experiment 3:4. What happens to the other colors of light when they reach a

RED filter?Experiment 4:5. What would you see on a screen if you shined white light

through a red filter then a blue filter?6. Which color is the absence of light?7. Is my hypothesis true or false?; I will explain myself.8. Complete ABSTRACT FORM AND LAB REPORT
