Study Notes
Scientific Method
- Observation and questioning are the initial steps
- Research involves gathering information
- Hypothesis proposes a possible explanation
- Experiments test the hypothesis
- Results are documented
- Conclusions determine if the hypothesis is supported by the data
- Communication shares findings
Data Types
- Quantitative data is numerical.
- Qualitative data is descriptive.
Variables
- Independent variable is manipulated.
- Dependent variable is measured.
- Examples provided: plant growth/sunlight, heart rate/exercise duration, ice cream sales/temperature.
Graphs
- Independent variable on the x-axis.
- Dependent variable on the y-axis.
Results and Conclusions
- Results are compared to the hypothesis to draw conclusions
- Communication of results may include writing, presentations, or other formats.
Matter
- Matter breaks down into pure substances(elements and compounds) and mixtures(homogeneous and heterogeneous).
Pure Substances
- Pure substances have constant composition and properties.
- Elements cannot be broken down.
- Compounds are formed from two or more elements.
Mixtures
- Mixtures contain two or more substances not chemically combined.
- Heterogenous mixtures are not uniform throughout.
- Homogenous mixtures are uniform throughout.
Atoms and Molecules
- Atoms are composed of protons, neutrons, and electrons.
- A molecule is two or more atoms held together by chemical bonds.
- A compound is a substance formed from two or more elements chemically combined.
Chemical Properties
- Chemical properties describe how a substance changes or reacts to form new substances.
- Examples: ability to burn, tarnish, decompose.
Physical Properties
- Physical properties can be observed or measured without changing the substance's composition.
- Examples: volume, mass, size.
Intensive and Extensive Properties
- Intensive properties do not depend on the amount of substance.
- Extensive properties depend on the amount of substance.
States of Matter
- Solids, liquids, and gases are the three states of matter,
- Their particles are arranged differently with varying energy levels.
Solutions
- Solutes are dissolved substances.
- Solvents are the dissolving medium.
Examples of Solutions
- Chocolate milk, sugar water, iced tea, lemonade, jello, coffee, and saline water are named as examples.
Chemical Changes
- Chemical changes result in new substances being formed.
- Chemical reactions involve energy changes, which can be released (exothermic) or absorbed (endothermic).
Water Properties
- Water's properties (e.g., cohesion, adhesion, capillary action, surface tension) are related to its polarity
- Water is a universal solvent.
