The tiny unit that all living things are made of.
What is a cell?
The control center of the cell that contains genetic material and directs cell activities.
What is the nucleus?
The measure of how much matter is in an object.
What is mass?
The season when leaves change color and temperatures start to cool.
What is autumn (fall)?
This tiny, creepy critter often shows up in Halloween decorations or “haunted” houses and makes eight-legged webs.
What is a spider?
This thin, flexible barrier surrounds the cell and controls what enters and leaves.
What is the cell membrane?
The jelly-like substance inside a cell that holds organelles in place.
What is cytoplasm?
The basic substance that makes up all matter.
What is an element (atoms)?
Many birds do this to find warmer places and food during fall.
What is migrate (migration)?
These night-flying insects are often drawn to porch lights and spooky decorations in October.
What is a moth?
Cells that provide structure and support for your body are part of this system.
What is the skeletal system?
This organelle is known as the “powerhouse” of the cell because it produces energy.
What is the mitochondrion?
The chemical that carries genetic instructions inside living cells.
What is DNA (deoxyribonucleic acid)?
These funny-looking figures made of straw and old clothes appear in fields to scare away birds during harvest season.
What are scarecrows?
This type of gas can fill a fog machine or bubbling cauldron to create spooky, cloud-like effects. (Hint: It’s also a byproduct of cellular respiration.)
What is carbon dioxide (CO₂)?
This process happens in cells when they use food molecules to release energy for the body.
What is cellular respiration?
These structures in plant cells capture sunlight to make food during photosynthesis.
What are chloroplasts?
Some organisms are so small you need a microscope to see them; they are called this.
What are microorganisms?
This special “sun event” happens in fall when day and night are almost the same length, signaling the change of seasons.
What is the autumnal equinox?
This spooky Halloween science involves mixing ingredients to make a reaction that fizzes, foams, or bubbles.
What is a chemical reaction?
This principle states that all living things are made of cells, cells are the basic unit of life, and all cells come from other cells.
What is cell theory?
These tiny structures in a cell make proteins according to instructions from DNA.
What are ribosomes?
A group of similar cells that work together to perform a specific function.
What is a tissue?
Animals like squirrels and bears do this in fall to get ready for winter, storing food or finding safe places to sleep.
What is hibernation preparation (or storing food for winter)?
This tiny organism, sometimes found on rotting pumpkins or leaves, helps break them down and can make a glow under certain conditions.
What are fungi?
