Study Notes
Working Scientifically
- Students will learn how to define, write, and justify hypotheses - an idea about how something works that can be tested using experiments.
- Students will also learn about predictions - what will happen in an experiment if the hypothesis is correct.
- Students will learn how to define and apply the terms variable, controlled variable, independent variable, and dependent variable.
- Students will learn to construct graphs including bar/column graphs, pie graphs and line graphs.
- Students will learn to justify the appropriate type of graph to choose.
Properties of Matter
- Students will learn about the different states of matter such as solid, liquid and gas.
- Students will learn about the particle theory of matter, including the shape in a container, arrangement of particles, movement of particles, compressibility, and the force of attraction between particles.
- Students will learn about changes in particle arrangement as substances change state (melting, freezing, boiling, condensation, deposition, sublimation).
- Students will learn about the kinetic theory of matter and how it relates to the movement of particles at different temperatures.
- Students learn about the expansion and contraction of matter.
- Students will learn to define and identify examples of common elements, compounds, and mixtures.
- Students will learn to distinguish between pure substances (elements and compounds) and mixtures.
- Students will learn to distinguish between homogenous and heterogenous mixtures.
- Students will learn about the different types of mixtures including suspensions, colloids, emulsions, and solutions.
- Students learn about aqueous mixtures in terms of solute, solvent, and solution.
- Students will learn about the importance of water as a solvent in aspects such as daily life, industries, and the environment.
- Students will learn to define solubility and how it relates to the particle theory.
- Students will learn how to distinguish between soluble and insoluble substances.
Density
- Students will learn to explain density in terms of the particle model.
- Students will be able to perform calculations using the formula p = m/V (p = density, m = mass in g, V = volume in mL).
The Scientific Method
- Students will learn to describe the steps of the Scientific method: observation, question, hypothesis, experimentation, drawing conclusions, and reporting results.
The Bunsen Burner
- There are three Bunsen burner flames: a safety flame, a luminous flame, and a non-luminous flame.
- The yellow/safety flame is a low heat flame.
- By fully closing the air hole, the temperature can reach up to 300 degrees.
Biology
- The nucleus in biology is the place where DNA replication and RNA processing takes place.
- The nucleus is surrounded by a membrane called the Nuclear Envelope.
- The nucleus is connected to the Golgi Body and the ER (Endoplasmic Reticulum), in a plant and animal cell.
- A prokaryote is a microscopic single-celled organism that lacks a nucleus and other organelles.
- An organelle is a cell structure that has one or more specific jobs to perform.
- A unicellular organism is made up of one singular cell.
- Multicellular means an organism is made up of more than one cell.
- Autotrophic means the organism can make its own food like photosynthesis.
- Plant cells have a rigid protective outer layer called a cell wall.
- A phylum is a group of closely related classes of organisms.
- Mrs Gren is an acronym that can be used to identify whether something is living or not, standing for movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition.
