SCIENTIFIC METHOD AND ATTITUDES
A possible explanation or “educated guess” to your problem.
Hypothesis
Who invented the microscope?
Hans and Zacharias Janssen
What did Isaac Newton invent?
He demonstrated through his PRISM that white light is a combination of all the colors of the rainbow.
A ________ mixture, such as salad dressing, has components that are not equally distributed and can be easily separated by simple physical means like decantation.
Heterogeneous
A can of shaving cream produces a fluffy white substance filled with tiny gas bubbles inside liquid soap.
Foam
A scientist who records all results carefully, even mistakes, is showing this attitude.
Honesty
A type of telescope that gathers and focuses light primarily using lenses.
Refracting Telescope
Father of Nuclear Medicine in the Philippines
Paulo Campos
What separation technique involves pouring off a liquid, carefully leaving the heavier solid component undisturbed at the bottom of the container?
Decantation
You use toothpaste to brush your teeth. It looks like a smooth paste where fine solid particles are dispersed in water.
Sol
This scientific attitude means being willing to question ideas and not accepting something without proof.
Skepticism
A small heating device that uses alcohol as fuel.
Alcohol Lamp
She discovered the elements polonium and radium and studied radioactivity.
Marie Curie
_______ are characterized by particles that are large enough to be easily seen with the naked eye and will settle to the bottom of the container over time.
Suspension
You pour milk into a glass. It looks smooth and uniform, but it is actually tiny fat droplets dispersed evenly in water.
Emulsion
At the end of an investigation, scientists write a statement about what the results mean.
Draw a conclusion
Instrument used to measure the mass of an object by balancing it with known masses using three notched beams.
Triple Beam Balance
Father of Genetics
Gregor Mendel
What is the main difference between a compound and mixture?
A compound is when 2 or more elements chemically combined, while a mixture is when 2 or more substances are physically combined.
A dense fog covers the street in the early morning. Tiny water droplets are suspended in the air, making it hard to see.
Aerosol
Marie Curie continued her research on radioactivity despite difficulties and risks. She showed this attitude.
Perseverance
A conical glass container used for mixing, heating, and storing chemicals.
Erlenmeyer Flask
Which scientist developed the theory of evolution by natural selection?
Charles Darwin
Which specific type of colloid where the dispersed particles are a liquid, and the dispersing medium is also a liquid (like mayonnaise).
Emulsion
Cheese is made when milk solids are trapped in a thickened liquid structure, creating a semi-solid product.
Gel
