Answer:
Objective(s):
In your own words, what was the purpose of this lab?
To explain how different materials make light bend.
Hypothesis:
In this section, please include the if/then statement you developed during your lab activity. This statement reflects your predicted outcome for the experiment.
If I project light rays through (choose one: air, water, glass), then they will refract, or bend, the most.
If I project light rays through glass, then they will refract the most.
Procedure:
Please be sure to identify the test variable (independent variable) and the outcome variable (dependent variable) for this investigation. Remember, the test variable is what is changing in this investigation. The outcome variable is what you are measuring in this investigation.
Test variable (independent variable):
Outcome variable (dependent variable):
Select Intro to begin.
Once the simulation loads, you will drag the protractor onto the screen so that the 0 lines up with the dotted line in the center of the screen.
You will test all three materials in the bottom, blue half of the screen: air, water, and glass.
Record your observations of how the light rays interact as they pass from air, on the top of the screen, through the three materials on the bottom of the screen
Data:
Record the data from each trial in the data chart below. Be sure to fill in the chart completely.
Material
Interactions
List any observations you made as the light rays passed from the air on the top of the screen to the selected material on the bottom of the screen.
Evidence
Using the protractor, measure the angle as the light passes from the top material to the bottom material on the screen. Also, note the index of refraction for each as indicated on the screen.
Trial One
Air on top
The light goes straight through the air
Angle:
Acute
Index of refraction:
1.00
Air on bottom
Trial Two
Air on top
The light bends in the water
Angle:
Actute
Index of refraction:
1.34
Water on bottom
Trial Three
Air on top
The light almost goes straight down when it hits the glass
Angle:
Acute
Index of refraction:
1.60
Glass on bottom
Conclusion:
Your conclusion will include a summary of the lab results and an interpretation of the results. Please write in complete sentences.
Did your data support your hypothesis? Use evidence to explain.
Yes it did, the glass index refraction (1.60) is higher than the other ones.
Which material refracted the light rays the most: air, water, or glass?
glass
Which material refracted the light rays the least: air, water, or glass?
air
How does density affect refraction?
It reflects light.
Diamonds are a very dense material. Predict what would happen to the light ray if you projected it from air through a diamond.
The light would reflect everywhere,
Explain where you observe reflection, refraction, and absorption of light in your everyday activities.
In mirrors and when light from a window hits a glass of water.
Mira is testing objects for her science experiment. She has a chart listing the mystery objects' densities, but no other information.
Object Density
A 12 g/cm³
B 9 g/cm³
C 3 g/cm³
D 6 g/cm³
She places each object in a large bowl of water in order to determine if any float. Which of the objects, if any, will float?
A. A
B. C
C. All objects will float
D. No objects will float

Explain homeostasis and why it’s important to the body
Answer:
Homeostasis regulates your body. When you are too hot, your body produces sweat to cool you down. When you're cold, you muscles shiver to generate warmth. When you have high glucose levels in your blood, your pancreas excretes insulin, and when blood glucose is too low, then it excretes glycogen. Homeostasis basically keeps your body from losing control and it helps you survive.

Why are young plants like but not identical to their parents?
Answer:
Dna
Explanation:
because the plants adapt to the dna of the other plants I think
Fossils of the Dorudon, an aquatic mammal that lived over 40 million years ago, show a whale-like animal that had small, underdeveloped hind limbs. Which best explains how fossils like the Dorudon support the theory that plant and animal life has evolved over time?
Answer:
they prove that animals evloved from a sinle anncestor

Explain the cell theory
Answer:
Explanation:
The cell theory basically just tells you that all living things have more than one cell and that cells are made from other cells. It basically just tells you that cells are our foundation for life, without cells we can't live.
For, example, blood cells. If we didn't have blood cells our body's organs can't get the oxygen and nutrients they need to survive. Without blood cells we could get weak or we could just die instantly.
Hope this helps!!!
Temperature can affect density in certain ways. If the temperature decreases, what effect can that have on the density of a substance?
Liquid water at 25 deg is so rapidly breaking bonds between H2O units and reforming them that extra water molecules get trapped inside the water lattice. This is the reason why liquid water is more dense than solid water.
The bonds in water break more slowly as temperature decreases and the structure tend to trap fewer extra water molecules. At low temperature, more of the water has the same lattice as ice.
Wikipedia, Water Density
It is possible to have liquid water at temperatures well below 0 deg C. Molecules in this supercooled water are free to move. Bonds are made and broken. The long range structure is not perfect but the short range structure of supercooled water is very much like ice. Adding a crystal to supercooled water causes instantaneous ice formation.
