Ecosystems & Slick Solutions
Big Ideas:
Vocabulary: ecosystem, producer, consumer, decomposer, inter-dependence, dependence, living, non-living, resources, balance, interaction, ecocolumn, pollutant, variable, pH level, human impact, trade-off, fair test
Big Ideas:
- All living organisms in an ecosystem depend on energy from the Sun.
- Organisms and their environments are interconnected.
- Changes in one part of the system will affect other parts of the system.
- Humans can alter the living and non-living factors within an ecosystem, thereby creating to the overall system.
- Humans study ecosystems to preserve and sustain the quality of life on earth.

Mixtures and Solutions
Big Ideas:
Vocabulary: mixture, solution, evaporation, filtration, mass, saturation, solubility, solvent, solute, dilute, volume, concentration, proportion
Big Ideas:
- The properties of a mixture allow it to be separated into its individual components.
- Physical properties of a solute will determine how much of it will dissolve in water.
- Solutions have different concentrations dependent upon the proportion of solute to solvent.
- The concentration of a solution determines its use.

Motion & Design
Big Ideas:
Vocabulary: motion, speed, distance, time, force, variables, friction, load, energy, stored energy, mass, air resistance, balanced forces, unbalanced forces
Big Ideas:
- Moving objects have energy. When moving objects interact they transfer energy through forces. Energy can also be stored in certain materials.
- Scientific inquiry involves asking scientifically-oriented questions, collecting evidence, forming explanations, connecting explanations to scientific knowledge and theory, and communicating and justifying the explanation.
