Matter & Energy
This type of mixture looks uniform throughout and cannot be easily separated.
What is a homogeneous mixture?
This term describes a group of living and non-living things interacting in an area.
What is an ecosystem?
This form of heat transfer occurs in liquids and gases due to movement.
What is convection?
This type of load causes a structure to be stretched.
What is tension?
This type of variable is intentionally changed by the scientist to test its effect (only 1 thing changes)?
What is the independent variable?
These are substances made of only one type of particle.
What are pure substances?
This is an organism that makes its own food using sunlight.
What is a producer?
This is the transfer of heat through direct contact.
What is conduction?
Why are triangles commonly used in bridges and towers?
What is they distribute forces evenly and provide stability?
Why is it important to repeat an experiment multiple times?
What is to increase reliability and identify consistent patterns? To make a test fair.
This property describes how much solute can dissolve in a solvent at a given temperature.
What is solubility?
This human activity leads to habitat loss and reduced biodiversity.
What is deforestation?
This human activity increases greenhouse gases and contributes to climate change.
What is burning fossil fuels?
A beam bends under weight. What type of stress is acting on the top vs. bottom of the beam?
What is compression on top and tension on bottom?
A hypothesis must be written in this format to clearly show cause and effect.
What is “If…then…because…”?
This is a molecule or particle that is distributed in a solvent.
What is a solute.
This is when one organism benefits and the other is harmed.
What is parasitism?
Explain how insulation reduces heat transfer using particle theory.
A: What is it traps air, slowing particle movement and reducing energy transfer?
This simple machine is the main mechanism used in a catapult.
What is a lever?
A graph shows a straight upward trend to the right, What type of relationship does this suggest?
What is the universal solvent?
What is water?
This word comes from Greek origin meaning “together” and “living” and describes a close interaction or relationship between two different species.
What is symbiosis?
What is the greenhouse effect?
What is the trapping of heat by gases in the atmosphere?
After release, stored energy changes into this form.
What is kinetic energy?
A student changes both temperature and light while testing plant growth. Why does this weaken the investigation?
What is .. you can only have 1 independent variable in an experiment to determine cause and effect?
