Scientific Principals:
- An object can be seen if four conditions are met: there is an object, an eye, a source of light, and a direct path between the object and the eye.
- Light must enter the eye or sensor to be seen or detected.
- The brighter an object appears, the more light that reaches the eye or detector from it.
- Light travels in straight lines.
- Light continues traveling until it reaches an object that scatters or absorbs it.
- A shadow is formed behind an object that blocks the path of light.
- A shadow is seen by detecting that less light reaches the eyes from it than from the area surrounding it.
- Scattering occurs when light bounces off an object in all directions. This occurs when the surface of the object is rough and unpolished.
- Reflection occurs when light bounces off an object only in a certain direction. This occurs when the surface of the object is smooth and polished.
- A reflection of one object is seen in a second object only if the second object reflects light, not if it scatters it.
- Some objects are transparent and let light pass through them.
- When light reaches an object, it is scattered (or reflected), transmitted, absorbed, or some combination of these.
- Light can make things happen when it is absorbed.
- When different colored lights are mixed, they appear as a new color, brighter than the original colors.
- White light is a mixture of all colors of light—it is the brightest color. Black is the color associated with the absence of light.
- Filters color light by absorbing certain colors and transmitting the rest.
- Colored objects scatter only certain colors of light and absorb the rest.
- There are many different wavelengths of light. Most of these cannot be seen.
- Different wavelengths of visible light appear to us as different colors.

We will use the following with our problem solving focus:
Student’s Science Project Finds Toilet Water Cleaner Than Restaurant Ice.
A seventh-grade student in Florida was awarded first place for her science fair project that found some toilet water is cleaner than ice served at area restaurants, according to a Local 6 News report.
Student Jasmine Roberts checked five fast-food restaurants near the University of South Florida and found there was more bacteria in the ice people were drinking than there was in the same restaurants’ toilet water.
“When I get ice, sometimes I order ice just to chew on it, and now I know I’m not going to do that anymore just because of the amount of bacteria I found,” Roberts said.
Since the Benito Middle School student completed the project, she has received international attention.
Dr. Daniel Lim, who is a microbiology professor at USF, said he was not surprised the toilet water had less bacteria than restaurant ice.
If you don’t clean the receptacle, the materials routinely, there may be a possibility of biofilm or residual material remaining in that receptacle,” Lim said.
Jim Griffith, the president of Suncoast Ice Machines, sells, leases and services ice machines. He also wondered about the cleanliness of the ice dispensers the students sampled.
The Florida Department of Business and Professional Regulation checks ice machines during restaurant inspections twice a year.
Roberts won $800 for the project.
Let’s use Jasmine’s experiment as an example for our problem solving focus:
“My hypothesis was that the fast food restaurants’ ice would contain more bacteria that the fast food restaurants’ toilet water.”
After testing water from the toilets and ice taken from 5 area fast food restaurants, her conclusion:
“I found that 70-percent of the time, the ice from the fast food restaurant’s contain more bacteria than the fast food restaurant’s toilet water.”
4 Parts of a Scientific Experiment: (Textbook pages 754 & 755)
- Independent Variable—What is measured; the manipulated variable
- Dependent Variable —Results, data
- Constant——————Conditions of the experiment that do not change
- Control——————-Used for comparison to independent variable
Placebo—-a fake independent variable to understand the effect of just using the independent variable
- Retinal fatique: We will use the blank sheets and those with green , blue, and red dots to explore —Make a data table :
Color eyed for 30 seconds | Reaction | Observation |
Red | ||
Blue | ||
Green |
- Comics and dissecting scopes or magnifying lenses.
light | clear path of view | how light travels | wavelength | cone | refraction |
eyes | neurons | speed of light | ROYGBIV | shadow | lens |
brain | object | retina | photoreceptor | electromagnetic spectrum | |
contrast | shadow | pupil | rod | reflection |

Its Flu Season and we are starting the school with safety:
Focus on Safety (For periods 2, 3,& 4):
Please have students:
- Use glue sticks to attach the handout to a page in their notes
- View
- Safe coughing, sneezing video:
- How to Cough and Sneeze Hygiencally: http://pisdtv.pisd.edu/instructional-technology/features/O_iad_w93ed1UzUxwjwT
b . Mythbuster videos:
- The Safe Sneeze
- Bathroom Hygiene : https://www.youtube.com/watch?v=1pFww_EaLiY
- Have students Copy (in their science notes after the page they glued their “Safety Rules”& Check off terms heard in class:
- Identify a problem
- Analyze and Write Conclusions
- Form a Hypothesis
- Communicate Results
- Collect Data
- Perform an Experiment
- Record Data
Tell students that not only is it flu season, but we share space, and in a science class we need to approach this hygienically;
- It is estimated that washing hands with soap and water could reduce diarrheal disease-associated deaths by up to 50% 1.
- that 80% of infections are spread, Handwashing can reduce the risk of respiratory infections by 16% 4.
- More than 50% of healthy persons have Staphylococcus aureus living in or on their nasal passages, throats, hair, or skin 6.
Asked why may it is appropriate address this in a science class.

Science Safety Rules Period __
The Bikini Bottom gang has been learning safety rules during science class. Read the paragraphs below to find the broken safety rules and underline each one. How many can you find?
SpongeBob, Patrick, and Gary were thrilled when Mr. Krabbs gave their teacher a chemistry set! Mr. Krabbs warned them to be careful and reminded them to follow the safety rules they had learned in science class. The teacher passed out the materials and provided each person with an experiment book.
SpongeBob and Gary flipped through the book and decided to test the properties of a mystery substance. Since the teacher did not tell them to wear the safety goggles, they left them on the table. SpongeBob lit the Bunsen burner and then reached across the flame to get a test tube from Gary. In the process, he knocked over a bottle of the mystery substance and a little bit splashed on Gary. SpongeBob poured some of the substance into a test tube and began to heat it. When it started to bubble he looked into the test tube to see what was happening and pointed it towards Gary so he could see. Gary thought it smelled weird so he took a deep whiff of it. He didn’t think it smelled poisonous and tasted a little bit of the substance. They were worried about running out of time, so they left the test tube and materials on the table and moved to a different station to try another experiment.
Patrick didn’t want to waste any time reading the directions, so he put on some safety goggles and picked a couple different substances. He tested them with vinegar (a weak acid) to see what would happen even though he didn’t have permission to experiment on his own. He noticed that one of the substances did not do anything, but the other one fizzed. He also mixed two substances together to see what would happen, but didn’t notice anything. He saw SpongeBob and Gary heating something in a test tube and decided to do that test. He ran over to that station and knocked over a couple bottles that SpongeBob had left open. After cleaning up the spills, he read the directions and found the materials he needed. The only test tube he could find had a small crack in it, but he decided to use it anyway. He lit the Bunsen burner and used tongs to hold the test tube over the flame. He forgot to move his notebook away from the flame and almost caught it on fire.
Before they could do another experiment, the bell rang and they rushed to put everything away. Since they didn’t have much time, Patrick didn’t clean out his test tube before putting it in the cabinet. SpongeBob noticed that he had a small cut on his finger, but decided he didn’t have time to tell the teacher about it. Since they were late, they skipped washing their hands and hurried to the next class.
