CHEMISTRY 11 NOTES ON THE SCIENTIFIC METHOD
Thinking like a scientist is not hard, you have to put yourself into a process. To think like a scientist you must use the SCIENTIFIC METHOD.
CHEMISTRY 11 NOTES ON THE SCIENTIFIC METHOD
Controlling Variables: • Controlled Variables: The conditions that remain unchanged in an
investigation. (temperature, light, etc.) • Variable: The condition that is changed to be tested.
Example: Did the fertilizer work? How do you know?
Control AZOTOVIT Fertilizer

Observing: • Quantitative Observations: Measurable. THINK #’S • Qualitative Observations: Observations which cannot be measured include
colour, taste, clarity, and state of matter. THINK QUALITIES Spot the 8 differences

Measuring: • Measuring is the most important part of doing science. The most common
units are length, mass, volume, temperature. • Units for Measuring length: mm,
cm, m, km • Units of Volume: L, mL, cm3 when measuring the volume of a liquid, you use a graduated cylinder or beaker. You have to look at the meniscus. The meniscus is the curvature of the beaker level of water. Measuring Mass: Mass is the amount of matter in an object. The units of mass are grams (g), milligrams (mg) kilograms (kg) and metric tones (t) Scientists use balances to measure mass. Triple-beam balance Classifying: When you classify things you sort them into groups based on similarities and differences. This is a Sea Sponge. What is it? Plant, Animal, Fungus, Bacteria, etc…

Inferring: An inference is a possible explanation of something you observe. It is an educated guess based on your experience, knowledge, and observations.

Communicating: Scientists present their data in charts, tables, or graphs and in written reports. We will talk more about this part later. Creating Models: A scientific model is an idea, illustration, or object that represents something in the natural world.
