Cells
This structures acts like the "brain" or control center of the cell, housing the cell's genetic material (DNA).
Nucleus
This type of change alters the form or appearance of a substance (like melting ice or tearing paper) without creating a new substance.
Physical Change
This is the energy of motion; anything that is moving has it.
Kinetic Energy
Sound is produced by these rapid, back-and-forth movements of matter.
Vibrations
This type of eclipse occurs when the Moon passes directly between the Sun and Earth, blocking the Sun's light.
Solar Eclipse
Found only in plant cells, this rigid outer layer provides structural support and protection.
Cell Wall
The ability of a metal to be hammered or rolled into thin sheets is known as this physical property.
Malleability
Stored energy, or energy based on an object's position or structure, is known as this.
Potential Energy
Sound waves cannot travel through this completely empty space because there are no particles to carry the wave.
Vacuum
A lunar eclipse can only take place during this specific phase of the moon.
Full Moon
Known as the "powerhouses" of the cell, these organelles convert glucose into usable energy (ATP) through cellular respiration.
Mitochondria
Flammability and the tendency to rust are examples of this type of property, which describes a substance's ability to change into something entirely new.
Chemical Property
According to this fundamental law, energy cannot be created or destroyed, only transformed from one form to another.
Law of Conservation of Energy
This property of sound refers to how high or low a sound seems, and it is directly determined by the wave's frequency.
Pitch
This is the name given to the fully dark, inner part of a shadow during an eclipse where the light source is completely blocked.
Umbra
This is the green pigment found inside chloroplasts that absorbs sunlight for photosynthesis.
Chlorophyll
This classic sign of a chemical reaction involves the sudden formation of a solid when two liquids are mixed together.
Precipitate
This type of heat transfer occurs through the direct contact of particles in a solid, like a metal spoon heating up in hot soup.
Conduction
Sound travels fastest through this state of matter because its particles are packed tightly together.
Solid
This is the alignment order of the three celestial bodies (Sun, Earth, Moon) during a lunar eclipse.
Sun, Earth, Moon
Unlike eukaryotes, these simple, single-celled organisms (like bacteria) lack a nucleus and membrane-bound organelles.
Prokaryotes
Calculated by dividing mass by volume, this property determines whether an object will sink or float in water.
A solar panel converts radiant (light) energy directly into this form of energy.
Electrical energy
Measured in decibels (dB), this term describes the energy or loudness of a sound wave, represented by the height of the wave.
Amplitude
During a solar eclipse, what specific phase must the Moon be in to block out the Sun?
New Moon
