The smallest unit that can carry out all life processes.
What is a cell?
White, frozen precipitation that falls in cold weather.
What is snow?
The process by which plants use sunlight to make glucose and oxygen.
What is photosynthesis?
Newton’s law stating an object resists changes in motion unless acted on by a net external force.
What is Newton’s First Law?
This evergreen tree is commonly decorated at Christmas.
What is a Christmas tree?
The structure that controls what enters and leaves a cell.
What is the cell membrane?
The season that includes December, January, and February in the Northern Hemisphere.
What is winter?
The process that breaks down glucose to release energy (producing CO2 and water).
What is cellular respiration?
The physical quantity equal to mass times velocity.
What is momentum?
These tiny organisms help break down leftovers and turn them into soil.
What are bacteria (or fungi)?
Cells that have a nucleus and organelles (examples: plant and animal cells).
What are eukaryotic cells?
A frozen form of water that forms on surfaces overnight when temperatures drop.
What is frost?
The two raw materials (reactants) plants need for photosynthesis.
What are carbon dioxide and water?
If you double the net force on an object while mass stays the same, this happens to its acceleration.
What is the acceleration doubles?
Lights on a tree need this to light up a closed path for electricity to flow.
What is a circuit?
Organisms made of a single cell that perform all life functions in that one cell.
What are unicellular organisms?
The loud sound you hear when water in the air freezes and then thaws quickly (often during storms).
What is thunder? (or What is thunder from lightning?)
The organism type that makes its own food from sunlight.
What is a producer (autotroph)?
Why action reaction forces do not cancel each other for a single object.
What is: they act on different objects, not on the same object?
Frozen water that falls from the sky in winter; each piece often has a unique pattern.
What is a snowflake?
The rigid layer found outside the cell membrane in plants, fungi, and many bacteria.
What is the cell wall?
These animals often migrate or change behavior in winter to survive cold temperatures
What are migratory birds?
Short explanation: how photosynthesis and cellular respiration connect in ecosystems.
What is: Photosynthesis stores energy in glucose; respiration releases that energy and cycles carbon, hydrogen, and oxygen between organisms and the atmosphere?
In a collision between a heavy cart and a light cart, which typically has the larger change in velocity and why?
In a collision between a heavy cart and a light cart, which typically has the larger change in velocity and why?
These newer holiday lights use less energy and stay cooler than old incandescent bulbs.
What are LED lights?
