Unit 1 Cells
This is the basic unit of all living things.
Cell
This is the basic building block of all matter. Everything around you is made of these.
atom
This is how we measure how long something takes. We measure it in seconds, minutes, or hours.
time
This organ is like the body's computer or control center. It sends messages to all parts of the body.
brain
Which country is Ms. Sharon from?
the Philippines :)
This is the "brain" or control center of the cell. It contains the DNA.
nucelus
This is the center of an atom. It contains protons and neutrons.
nucleus
This is the speed of an object in a specific direction. For example, "50 kilometers per hour to the north."
velocity
This organ is like a powerful pump. It pushes blood to every part of your body.
heart
It is a scientific instrument designed to produce magnified, high-resolution images of objects too small to be seen with the naked eye.
microscope
This is the powerhouse of a cell.
mitochondria or mitochondrion
This is what you get when two or more atoms join together.
molecule
We measure force in this unit, named after a very famous scientist.
newton
These two sponge-like organs are what fill up with air when you breathe in. They take oxygen into your body.
lungs
What kind of directions are west and south?
negative
This is the jelly-like substance that fills the cell and holds the organelles.
cytoplasm
This state of matter has a fixed shape and a fixed volume. The particles are packed tightly together.
solid
This is a non-contact force that pulls objects toward the center of the Earth.
gravity
This organ is like a mixing bowl. It uses strong acids and muscles to churn food into a soupy liquid.
stomach
What is the net force if two forces acting on an object are 20N, East and 10 N, West?
10N, East
This is a type of cell that has a nucleus and other organelles. Plant and animal cells are this type.
eukaryotic
This scale measures how acidic or basic a liquid is. It goes from 0 to 14.
pH scale
If you run one lap around a 400-meter track and end back where you started, what is your displacement?
0
These two bean-shaped organs act like filters for your blood. They take waste out of the blood to make urine.
kidney
What is the exact pH of water?
7
