Types of Forces
The two main categories of forces
Contact and Non-Contact forces
Gold, Iron, and Silver can all be found on the periodic table. These are examples of
Elements
This organelle is found in plants ONLY and is the site of photosynthesis
Chloroplast
A plant in a rainshower displays which two Earth spheres?
Biosphere and Hydrosphere
What is formula for calculating density?
D=M/V
This contact force is simply described as push or pull
Applied Force
NaCl is known as table salt. What would this be classified as?
Compound
This body system is responsible for breaking down nutrients. Starts in the mouth.
Digestive System
Wildfires are known to affect the biosphere since they affect trees and animals, but what is the other MAIN sphere that is affect due to the fires? WHY?
Atmosphere- Air pollution
When two individuals are fighting for limited resources such as water or shelter, it is this type of relationship?
Competition
This non-contact force talks about the force of attraction and repulsion between 2 magnetic poles.
Magnetic Force
I'm making a cake for my favorite class. Is this a physical or chemical change? WHY?
Chemical- we are changing/altering the substance to make something new. Can not be reversed.
Why do plant cells have 1 large vacuole when animal cells have multiple small ones?
Possible answer: Plants cannot move- they need to store water or nutrients.
Scientists have determined that convection currents are responsible for plate movement, where are these convection currents located?
Mantle
Which planet in our Solar System has the most similar atmosphere to Earth ?
Mars
Hitting the brakes while riding a bike would be an example of this contact force.
Friction
Slicing lemons and Melting Ice are all examples of physical changes. How would you describe a physical change?
Possible answers:
Physical changes are a change in matter, can be reversible, does not change chemical properties
What are two body systems that help us get rid of waste and maintain homeostasis?
Excretory and Respiratory Systems
When two plates collide, the oldest layer always goes beneath the Earth. This process is known as
Subduction
What are the levels of organization starting from Smallest to Largest (HINT- 5 levels)
Cell, tissue, organ, organ systems, organism
You rubbed a balloon on your hair and held the balloon next to the wall. You observed the balloon stick to the wall.What force is responsible?
Electrical force
This law states that the total mass of products must be equal to the total mass of the reactants. What is this law?
Law of Conservation of Mass
What are the Three Principles of the Cell Theory?
All organisms are made up of one or more cells
Cells are the basic unit of life
Cells come from pre-existing cells
Which of these may be caused by an interaction between the hydrosphere and geosphere?
-Water Cycle
-Photosynthesis
-Icebergs forming
Water Cycle
Photosynthesis is a process that all producers undergo to make their own food. What are the reactants (starting materials) and products (end results) of photosynthesis?
Reactants- Water, Light energy/Sun, Carbon Dioxide
Products- Glucose and Oxygen
