Particle Solutions
What state of matter has particles packed tightly in fixed, vibrating positions?
Solid.
What process do plants use to convert solar energy into chemical energy?
Photosynthesis.
What geometric shape provides maximum stability in truss bridge designs?
Triangle.
What supercontinent existed before plate movement separated it?
Pangaea.
What is the difference between a solute and a solvent?
Solute is the substance dissolved; solvent is the liquid that does the dissolving.
Define biotic factor and provide two local ecosystem examples.
Living components of an environment (e.g., black bear, lobster, spruce tree).
What internal pulling force stretches structural materials?
Tension.
Differentiate between weathering and erosion.
Weathering breaks down rocks in place; erosion transports the fragments away.
How does increasing temperature affect solid solubility?
Higher temperature increases solid solubility.
How does Netukulimk relate to sustainable resource conservation?
Netukulimk ensures resource extraction meets current needs without compromising future generations or ecological integrity.
Compare static loads and dynamic loads.
Static load is constant force and dynamic load is changing force. (Standing still vs. jumping up and down).
What geological process causes earthquakes?
Shifting tectonic plates.
Explain how filtration differs from evaporation when separating mixtures.
Filtration physically separates solids from liquids; evaporation removes the liquid by turning it into a gas and leaves dissolved solids behind.
How do biological indicators measure the health of a local waterway?
The presence, absence, or abundance of sensitive species reflects water purity and pollution levels.
Identify the two forces acting on top and bottom of a bending beam.
Compression acts on the top surface; tension acts on the bottom surface.
Name two pieces of evidence supporting continental drift theory.
Matching continental shorelines, identical fossil records across oceans, matching mountain formations, or paleoclimate evidence.
