Nature of Science
Define a law
Define homeostasis.
Maintaining an internal balance in a changing environment.
Which two systems are responsible for waste removal?
Digestive and excretory
The nucleus of an atom is made of which 2 parts?
Protons and Neutrons
List the three measurable properties of matter.
Mass, volume and density
Explain why we need constants
to make sure you are only changing and testing one thing in the experiment
Compare and Contrast cell wall and cell membrane
Cell wall- extra protection and support
Cell membrane- lets in certain materials
What are the main organs in the circulatory system?
Heart, arteries, blood, lungs
Identify what type of element would be located on the left side of the periodic table
Metals
List the 4 states of matter
Plasma, gas, solid, and liquid
Contrast independent and dependent variable.
Independent is the part of the experiment you change (thing being tested) Dependent is what you measure (the data)
Describe the difference between plant and animal cells.
Plants- cholorplasts, large central vacuole, cell wall
Describe the function of the digestive system.
Absorb nutrients and get rid of waste
Classify the electrical charges of the three parts of the atom, protons, neutrons and electrons.
Proton +
Electron -
Neutron 0
Define volume and tell it's units and how to calculate it.
Amount of space an object takes up, measured in cm^3 or mL, length x width x height
Predict what would happen if your experiment did not have a control group.
You wouldn't have anything to compare results to.
How are prokaryotic and Eukaryotic cells different?
Prokaryotic- more simple no nucleus or membrane bound organelles
Which type of pathogen is can be treated by rest or antiviral drugsand tell why they are considered not alive.
Virus, they cannot reproduce on their own.
Explain the mnemonic device APE MAN.
Atomic number=proton #= electron #
Mass #- Atomic #= neutron #
What happens to particles in matter as you increase kinetic energy? How does it affect density?
They start moving faster and have less spacing. It becomes less dense.
You were given an experiment on finding how tall a plant will grow in a month depending on the type of soil being used.
Identify the following independent and dependent variable and what type of graph would best represent your data.
IV- type of soil
DV- height of plant
Graph- bar
What is the job of the mitochondria?
cell respiration- turn food into energy
Identify at least 3 system that are involved in the following scenario.
You hear the tardy bell, you start running to lunch, Mr. Forbes catches you in the hall while you are chewing gum, you start to sweat as he writes the detention.
Nervous
Endocrine
Musculoskeletal
Digestive
Excretory
Integumentary
If your atom has an atomic number of 6 what three things change when you add one proton?
Atomic number, atomic mass, element name, and charge
Which of the following is a physical property of matter?
mass, volume, density, flammability
density
