For some people, there is no such thing as Color!


Science and Visual Arts


Color Blindness, Eye anatomy, and Drawing the human eye.



Images/Video Resources


This is an interesting video about the Human Eye, it explains about the eye anatomy and its functions.




This is a very important documentary done by Laura Evans.  It's a documentary to understand the people who are color-blind.




These is a summary of the same documentary done above, but it will help you understand better with the questions included.




As you will find in your research, there are different kind of Color-blindness.  The one in the following video, is a very rare color-blindness condition.




Here is a sample of the Color-Blindness Test.  You have probably seen it before, they give them during eye exams.




Watch the following film:  A colour-blind boy discovers his independence through painting.

Best Short Film - BBC Night of Many Stars
Screened on 'Homegrown Hollywood' BBC2
Best Short Film - City Screen (Won Distribution in Picture House Cinemas)
Audience award - Shortcuts London Festival and Divercine Uruguay Film Festival

This is an interesting video which explains even though we might see color different than others, we still can perceive the same feeling through that color. 




This is a tutorial video created by me explaining how to draw the human eye in ONE minute.

Pay attention so you can draw yours on the tag board for the Eye Anatomy chart.


How to draw the human EYE from Dara K. Cepeda on Vimeo.


Here is another tutorial video on how to draw the human eye.







There is a famous quote that reads: “The eyes are the windows to our soul”.  With science, we have discovered that the eyes are actually the windows to our brain.  How can this happen? We only "see" after our brains interpret what's sent to them from our eyes. 






Watch this video so you can understand more about the process:





Luckily, for most of us our eye catches all the colors around us.  Our world is full of color thanks to these windows; our eyes. 


Have you asked yourself, how would it be like to wake up one day, and all of a sudden you realize there is something wrong with your eyesight.  Your world has been dimmed to a monochromatic, pale, and grayish or dull world!  There are many colors missing everywhere; the shirt that used to be purple is now pale blue!  Your bright green pants are now light brown! How can this happen?


Of course this can’t really happen from one day to another.  But, did you know there are people who were born like that? They are born with a condition that is called Color-Blindness.


Color-blindness is the inability to distinguish the differences between certain colors. This condition results from an absence of color-sensitive pigment in the cone cells of the retina, the nerve layer at the back of the eye.


Most color vision problems are inherited and are present at birth. Approximately 1 out of 12 males and 1 out of 20 women are color blind.


We normally see it like this




People with color-blindness condition see it like this



They can see shape, texture, but COLOR!

Sample Investigations/Teacher Resources



Being color blind can make it tricky to match your shirt and pants, but it's not a serious problem. People who are color blind can do normal stuff, even drive. Most color-blind people can't tell the difference between red and green, but they can learn to respond to the way the traffic signal lights up — the red light is generally on top and green is on the bottom.



The problem is many people are misinformed of the Color-Blind condition.  Some people think color-blindness is referring to a person who’s blind.  Other people believe color-blindness is when people who see “only” black and white colors, just like a black and white TV. 



For this assignment you will be working in teams of four.  Your team will have access to a laptop with internet access.


Your task is to investigate, search more about this condition. 

For example,

  • ·         What is color-blindness?
  • ·         How many different color-blindness conditions are out there?
  • ·         Can it get prevented?
  • ·         How can this affect a person’s life?
  • ·         Can we find a solution to color-blindness?
  • ·         How can people help other people with color-blindness?
  • ·         How are color-blind people different from us?
  • ·         How does the eye work differently than our eyes?
  • ·         What is the eye anatomy?
  • ·         How does the eye transmit color to the brain?
  •           How can we take care of our eyes?

And so on…


*You will be using the provided customized search engine for the research.


After you have found essential information, illustrations, visual aids, videos, etc. You will gather all of it together and create a five-slide Presentation with VoiceThread


Your team will also create an Eye Anatomy poster by drawing a human eye on white tag board.  These drawing posters will be posted on the “Science Hall”. 



*Watch tutorial videos provided on resources on how to draw the human eye, or use the customized search engine.

Students can create something like this for their presentation





This is a great sample about Color-blindness investigation


Here are some samples of the The Eye Anatomy Drawing.

Student Work


1. Read and analyze the scenario and situation.
Check your understanding of the scenario. Don't be tempted to start thinking about potential solutions or to start looking for information. 


1. List your personal understanding, ideas or hunches.

Now that you are familiar with Color-Blindness condition you will write everything you know about color-blindness. Describe your thoughts or ideas about how to solve the problem. There are not incorrect answers in this step, just feel free to brainstorm your ideas.


2. List what is known.

 With your team use all the information available in the scenario to list everything that you know about color-blindness. You do not have to conduct any research yet. Just use the information given and write the facts that you already know about color-blindness.

3. List what is unknown.

With your team, make a list about what you do not know and would like to learn. List all the questions you will need to answer to solve the problem.  


4. List what needs to be done.
"What should we do?" List actions to be taken, e.g., question an expert, conduct research, go to a board meeting about topic. List possible actions.


5. Develop a problem statement.

You will be responsible for thinking and choosing one of the questions to solve the problem.  A problem statement should come from your analysis of what you know. In one or two sentences, you should be able to describe what it is that your group is trying to solve, produce, respond to, or find out. The problem statement may have to be revised as new information is discovered and brought to bear on the situation.

6. Gather information

Use all the resources available (Internet, library, etc) to research about the problem/topic and find a solution.

7. Present Findings


After you have found essential information, illustrations, visual aids, videos, etc. You will gather all of it together and create a five-slide Presentation with VoiceThread


Your team will also create an Eye Anatomy poster by drawing a human eye on white tag board.  These drawing posters will be posted on the “Science Hall”.

(A)  Scientific investigations and reasoning.

(i)  To develop a rich knowledge of science and the natural world, students must become familiar with different modes of scientific inquiry, rules of evidence, ways of formulating questions, ways of proposing explanations, and the diverse ways scientists study the natural world and propose explanations based on evidence derived from their work.

(ii)  Scientific investigations are conducted for different reasons. All investigations require a research question, careful observations, data gathering, and analysis of the data to identify the patterns that will explain the findings. Descriptive investigations are used to explore new phenomena such as conducting surveys of organisms or measuring the abiotic components in a given habitat. Descriptive statistics include frequency, range, mean, median, and mode. A hypothesis is not required in a descriptive investigation. On the other hand, when conditions can be controlled in order to focus on a single variable, experimental research design is used to determine causation. Students should experience both types of investigations and understand that different scientific research questions require different research designs.

(iii)  Scientific investigations are used to learn about the natural world. Students should understand that certain types of questions can be answered by investigations, and the methods, models, and conclusions built from these investigations change as new observations are made. Models of objects and events are tools for understanding the natural world and can show how systems work. Models have limitations and based on new discoveries are constantly being modified to more closely reflect the natural world.

(b)  Knowledge and skills.

(3)  Scientific investigation and reasoning. The student uses critical thinking, scientific reasoning, and problem solving to make informed decisions and knows the contributions of relevant scientists. The student is expected to:

(A)  in all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student;

(B)  use models to represent aspects of the natural world such as a model of Earth's layers;

(C)  identify advantages and limitations of models such as size, scale, properties, and materials; and

(D)  relate the impact of research on scientific thought and society, including the history of science and contributions of scientists as related to the content.



(1)  Perception. The student develops and organizes ideas from the environment. The student is expected to:

      (A)  illustrate themes from direct observation, personal experience

      (B)  analyze and form generalizations about the interdependence of the art elements such as color and     texture

(2)  Creative expression/performance. The student expresses ideas through original artworks, using a variety of media with appropriate skill.

      (C)  demonstrate technical skills effectively, using a variety of art media and materials to produce  sculptures and electronic media-generated art.
