The Scientific Method

Example

 

Modern science deals only with physical quantities, 

which we can express in quantitative rather than qualitative terms.  

bullet The scientific method begins with careful observations of some phenomenon, 
bullet followed by a hypothesis, which tries to explain the observations. 
bullet Scientists then test the hypothesis through experimentation.  If the hypothesis correctly predicts the results of the experiments and it is general enough  to correctly predict behavior not previously observed it may be accepted as theory.  
bullet A theory with an extremely wide range of proven validity and application is called a physical law. 

Laws are generalizations, principles, or patterns in the natural world. Theories are explanations of those generalizations. 

Laws are discovered. Theories are developed.

Graphing in Science

 

 

You are expected to graph in science to show your results.  Make sure you understand the basics of graphing line graphs, lines of best fit, scatter plots, and spread sheets. 

You will need to know the difference between the independent variable and dependent variable and label your graph properly.

*Remember, there is no such thing as negative in the Kelvin scale or K, it's just K.

Kelvin scale begins at absolute zero, (-273.15oC).

Absolute Zero is the coldest temperature, that means it's the temperature at which molecules (of any substance) have no more kinetic energy they can give up.

This is also where kinematics comes into play. Kinematics is the science of describing the motion of objects using words, diagrams, numbers, graphs, and equations. One dimensional means in motion in a straight line.  Therefore, when we talk about one dimensional kinematics, we will use graphs on a x-axis.  Motion can be forward or backward.

Electromagnetic Spectrum

Stand B: Energy

electromagnetic energy (electromagnetic radiation) is energy that moves through space or a material as a wave. Electromagnetic energy includes light, radio waves, infrared radiation, and x-rays. Electromagnetic energy travels at the speed of light, or 300,000 kilometers per second (186,000 miles per second).

Speed of Light in Vacuum: 3x10x8 m/s, 186,000 miles/sec
Speed of Light in Water: 2.25x10x8 m/s, 140,000 miles/sec
Speed of Light in Diamond: 1.24x10x8 m/s, 77,000 miles/sec

Frequency is the  property of a wave that describes how many wave patterns or cycles pass by in a period of time. Frequency is often measured in Hertz (Hz), where a wave with a frequency of 1 Hz will pass by at 1 cycle per second.

 

 

 

Visible Light

Acronyms, like ROY G BIV,  help us to remember the spectrum in order. 

700 nm                                                                                                   400nm

Red          Orange          Yellow           Green            Blue          Indigo         Violet


Pick an element from the menu to see its spectral signature.

 

The rainbow is really a continuous spectrum that shows us the different energies of light (from red to blue) present in visible light. But the electromagnetic spectrum encompasses more than just optical light - it covers all energies of light extending from low-energy radio waves, to microwaves, to infrared, to optical light, to ultraviolet, to very high-energy X- and gamma-rays.

White light is the combination of red, blue and green light.  As seen in the image above, adding different combinations of light, like red and blue to make magenta, will display varied frequencies of the light spectrum. 

Plants respond differently to frequencies (or colors) of light. This is why we use a plant grow light in the classroom terrarium.

Let's put this light thing into perspective using optics. 

By combining red, blue and green light in certain ways we can perfectly simulate any color the human eye can see.  The colors you see on this computer screen is an example of how video equipment leverages the color combinations. Most video equipment offers 256 intensities each of red, green & blue (RGB) light.  By altering the intensity of red, blue or green light would provide you with over 16 million combinations... way more colors than you can see with your own eyes.

The Solar System

Strand E: Earth and Space

The words solar system refer to the Sun and all of the objects that travel around it. This includes planets, natural satellites like the Moon, the asteroid belt, comets, and meteoroids.   

The Sun is the center of the solar system. It contains 99.86% of all of the mass in our solar system. Consequently, it exerts a tremendous gravitational pull on planets, satellites, asteroids, comets, and meteoroids.

  Classification

Strand H: The Nature of Science

sea star Classification, or taxonomy, is a system of categorizing living things. There are seven divisions in the system:

bullet Kingdom
bullet Phylum or Division
bullet Class
bullet Order
bullet Family
bullet Genus
bullet Species

Kingdom is the broadest division. There is no agreement about the number of kingdoms, but most scientists support either a four-kingdom (Animalia, Plantae, Protista, and Monera) or five-kingdom (Animalia, Plantae, Protista, Monera, and Fungi) system. For our purposes, we will use the five-kingdom system.

See Biology page for more Taxonomy Information.

Dissection

Barn Owl Tytonidae tyto alba

Owls are Birds of Prey, which means that they must kill other animals to survive. Their diet includes invertebrates (which include insects: spiders, earthworms, snails and crabs), fish, reptiles, amphibians, birds and other small mammals such as rats, moles, voles, etc.

Owl pellets are masses of bones, teeth, hair, feathers, scales, and insect skeletons.  These materials are blocked from reaching the intestines by the pyloric opening.  They are produced and regurgitated, not only by owls, but also by hawks, eagles, and other predatory birds that swallow their prey whole or in large pieces.  Because owls swallow their prey whole, each owl pellet contains virtually complete skeletons of the animals the owl ate the day before the pellet was formed.  By examining the bones of the animals eaten, the types of animals eaten, and the number of each species, the varied diet of an owl can be determined as well as the ecosystem in which it hunted its prey.

History of the Microscope

The invention of the microscope has allowed us to investigate a whole new world of tiny objects.

Microscopes magnify and resolve, which  are two very different things.

Magnification  \mag-ne-fe-'ka-shen\ n 1. apparent enlargement of an object 2. the ratio of image size to actual size
A magnification of "100x" means that the image is 100 times bigger than the actual object.

Resolution  \rez-e-loo-shen\ n 1. clarity, sharpness 2. the ability of a microscope to show two very close points separately

 Cell Review

Strand F: Processes of Life

Cell Theory


1.  All organisms are composed of one or more cells, and the life processes of metabolism and heredity occur within these cells.

2.  Cells are the smallest living things, the basic units of organization of all organisms.

3.  Cells arise only by division of a previously existing cell.

Meiosis

In Meiosis 1, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in Meiosis that generates genetic diversity.

Meiosis 2 is similar to mitosis. However, there is no "S" phase. The chromatids of each chromosome are no longer identical because of recombination. Meiosis II separates the chromatids producing two daughter cells each with 23 chromosomes (haploid), and each chromosome has only one chromatid.

This dihybrid matrix reveals the F2 from a breeding pair of corn snakes, Pantherophis guttatus.

This Punnett square could be used to find the genetic frequencies for flowers, dogs, etc.

 

Hardy Weinberg Equilibrium

p2 + 2pq + q2 = 1

We will use two alleles, A and a, with the dominant allele represented by the letter p and the recessive allele by the letter q.

p = the frequency of the dominant allele (represented here by A)
q = the frequency of the recessive allele (represented here by a)

p2 = frequency of AA (homozygous dominant)
2pq = frequency of Aa (heterozygous)
q2 = frequency of aa (homozygous recessive)

 

Mathematical Definitions:

Allele Frequencies = p (A) + q (a) = 1

Genotypic Frequencies = (p+q)2

p2 (AA) + 2pq (2Aa) + q2 (aa) = 1

 

This law assumes random mating in each generation and no disruption of allele frequencies or genotypic frequencies. If the end result is not 1, there is no equilibrium.

Possible reasons for population diversity (or lack of equilibrium): genetic drift, mutation, migration, and meiotic drive.
