8th Grade
What are the three most important properties of a wave
A simple wave has a repeating pattern with a specific wavelength, frequency, and amplitude
What are you studying this quarter
How temperature affects collision rates
What conversion takes place during photosynthesis
Light energy is converted to chemical energy
What is a feedback loop
A process where the output of a system is fed back as an input to influence future actions
The volume of the wave is related to what
The amplitude of the wave
How does temperature affect particle movement?
Colder temperatures means slower movement and warmer temperatures mean faster movement
What are the four main parts of a flower
The four main parts are the sepals, petals, stamens and the pistil
The pitch of a sound is related to what
the frequency of the wave
What happens when reactions happen very quickly
There is enough energy to break chemical bonds
What would happen if plants could not open and close the stomata
They could not regulate the absorption or release of gasses
How do negative feedback loops influence the Earth's climate
They stabilize the climate by counteracting or reducing greenhouse gas concentrations
What types of sound waves break glass
Waves with a very high amplitude
What is the Collision Theory
For a chemical reaction to happen, the reactant particles (atoms or molecules) must collide with each other in a specific way.
How do plants absorb sunlight energy
Plants absorb sunlight energy through pigments like chlorophyll in their chloroplasts
How does reforestation act as a climate change mitigation
Reforestation enhances carbon sequestration in forests mitigating the greenhouse effect
What is the best decibel and hertz level to break glass
500 Hz and at least 100 dB
What are the three conditions the particles must meet during a collision
They must collide
They must have enough energy
They must have the correct orientation
What are the two stages of photosynthesis
The light-dependent reaction and the light-independent reaction
What is the best way to mitigate the impacts of climate change
Combine renewable energy adoption, reforestation, and carbon capture
