Importance of Science--Illusions
Objectives: I can....
|
On the board
Illusions trick us into perceiving something differently than it actually exists, so what we see does not correspond to physical reality. Hence, the word illusion comes from the Latin verb illudere meaning, "to mock."
|
"Perception is not always reality". At some point make it clear that the natural world is full of illusions, and simple common sense doesn't always work to explain such illusions. This is where science is especially useful to help us dig out the real story....the most accurate explanation.

The Impossible Triangle
Impossible triangles drive students crazy. Impossible triangles or Penrose triangles create an image
that bends in an impossible manner. People hold certain untrue beliefs about objects. In the
Penrose triangle, the untrue belief is that the triangle's edges must connect. While they are hard to visualize, they actually help free your mind and are quite easy to draw.

Identify which questions can be answered through science and which questions are outside the boundaries of scientific investigation |

h Think back to the class discussion on the nature of science. Some questions are appropriate for science to address and others are beyond the realm of science. Remember that science must be consistent, observable, natural, predictable, testable, and is tentative. Put an “x” by the statements that science CAN address.
Homework answers: Scientific questions, based on the general guidelines explained, are: A, B, C, and I. Non-scientific question – would be: D, E, F, G, and H. |
Circle all the testable questions you see below.
Which animal is heavier, an adult rat or and adult mouse? What is the tallest building in the world? Why is blue better than pink? Which tastes better, Coca Cola or Pepsi? How fast can salmon swim?

Evidence--A thing or things helpful in forming a conclusion or judgment. Scientists weigh the evidence for and against a hypothesis.

Strong or weak evidence in science? Bigfoot? Medium foot?
There is a significant amount of evidence for Bigfoot - there are tracks, there are fuzzy photographs, there are hair samples, there are sighting reports - the problem is that it's not good evidence," said Benjamin Radford, managing editor of Sceptical Inquirer magazine.
"I liken it to a cup of coffee - if you have many cups of weak coffee, they can't be combined into strong coffee.
"It's the same with scientific evidence. If you have lots of weak evidence, the cumulative effect of the evidence doesn't make it strong evidence - and what science needs to validate a Bigfoot is strong evidence."
Ask yourself
- Is there any way of getting evidence? That is, is there something you can touch, see, hear, smell, or taste that you can find out more about?
- Could you do an experiment? That is, could you form a hypothesis (have an idea), work out what would happen if your hypothesis (idea) were true, and then test whether that is in fact what happens?
- Is there more than one source of evidence?
- What is the simplest explanation of the evidence? Is there an explanation which does not require us to believe in things which we have no evidence?
Strong Evidence

Weak Evidence
|
|
"My uncle said he once heard a loud grunting sound up near Bagby." Estacada Student Quote 2011 The quote above is an anecdote. An anecdote is a story. People generally find anecdotes highly compelling, while scientists are deeply suspicious of anecdotes. Anecdotal evidence is not scientific. We are fond of saying that the plural of anecdote is anecdotes, not data.
Read about some of our local Bigfoot sightings. What kind of evidence is presented? |

On the board
- hypothesis-explanation or idea about how things work
- scientific theory-a well-established explanation for scientific data, facts or phenomena.
- fact- and indisputable truth, something measurable
- It is a fact some people have been burned so completely by fire that even the bones are destroyed and much of the room is left untouched.
- It is a theory that once ignited the humans burn slowly like a candle using the body fat as a fuel source. Temperatures hot enough cause bones to crumble are produced.Small flames confined to the body do not allow the fire to burn out of control leaving most structures untouched. Hot gasses damage objects place high in the room
- One hypothesis is that static electricity build up ignites the person and they are consumed from within
- It is a fact that on June 30, 1908 in Tunguska, Siberia, an explosion equivalent to about 15 million tons of TNT occurred and blasted a huge area of trees flat.
- It is a theory that this explosion was due to a natural, extra-terrestrial phenomenon and not to an activity associated with man.
- One hypothesis is that a comet collided with the Earth (a competing hypothesis is that a small black hole collided with the Earth)
Just a Theory?
|
A scientific theory is not a guess, or just a good idea. It is a well-tested structure of interlinked ideas that unifies and explains observational facts. Scientific theories must make testable predictions, must be falsifiable, and must be open to revision and rejection.

2. We discussed the scale of cells, with students learning that white blood cells are only 6-8 μm in diameter (one micrometer (μm) is 3. equal to one-millionth of a meter). We then created class lists of tools scientists use.
4. Each class added to a growing list, and tomorrow we will categorize our large list.

Using the Metric Ladder
Try these steps each and every time you want to use use the metric ladder. 1. Find the spot (unit) on the ladder that has the same prefix as the measurement you are starting with 2. Locate the spot on the ladder that you want to convert your number to 3. Count the number of steps you must move on the ladder to make your conversion 4. Move the decimal in your original number this same number of steps and in the same direction (don't forget the Base step) (decigrams) |
An Example Using the Metric Ladder
How many dg (decigrams) are there in 5276.4 mg (milligrams)? 1. Put your pencil on the "milli" box 2. Put your finger on the "deci" box 3. Move the pencil until it meets your finger (two steps to the left) 4. Move the decimal two steps to the left to get your answer = 52.764 dg (decigrams) |

Metric Measuring Quiz
What a busy last few weeks! After the quiz today, students are filling out note cards listing the contents of their notebooks. After filling out the note card, students will have the remainder of the class period to write a self-reflection about how their experience in science class has been so far this school year. The reflection should consist of:
- What you have learned in science so far
- How you can use this learning outside of science
- What is going well for you in this class
- What you need to feel safe and successful in class

This measures how much mass a material has for a certain volume (space)
Density = mass/volume

- What are some advantages of using the water displacement method?
- List at least 3 possible sources of error during the lab.
- For each of your 3 sources above, explain how the error may be minimized in the future.
- Under the “Which Metal is the Cube Made of” column on your data table, you should have identified the metal based on a comparison with the given densities. Does your identification make sense? List other physical observations (besides density) that you made that may have lead you to confirm or question how you identitified the metal.
