Epic Ecosystems
The lowest level of an energy pyramid and the base of most food chains. They make their own food.
What are producers?
This greenhouse gas is released during the combustion of fossil fuels.
What is carbon dioxide? (and water vapor)
This is a physical property of matter that can be used to help identify an unknown substance. It is calculated by dividing the mass by the volume.
What is density?
This is the type of change that occurs in matter when its atoms are rearranged to form a new substance.
What is a chemical change or a chemical reaction?
This type of resource is sustainable (can be used again and again and never run out)
What is a renewable resource?
The variety of life in an ecosystem. It predicts the ability of an ecosystem to recover from disaster or disease.
What is biodiversity?
These are three types of renewable energy sources that would reduce the amount of carbon dioxide released into the atmosphere.
What are....
solar power, wind power, geothermal power, hydropower.
These are examples of pure substances and this is how they are modeled. *Use a white board*
What are elements and compounds?
What is by single colored dots and by two colored dots connected.
How many of each atom are in the reactants and products?
Mg + HCl 🡪 MgCl2 + H2
What is.....
Reactants: Mg=1, H=1, Cl=1
Products Mg=1, Cl=2, H=2
One piece of evidence that the climate has changed is that average global temperatures have risen over the past 50 years. These are two more data-backed pieces of evidence that the climate is changing. (You do not need to provide data, just the type of evidence).
Sea levels rising, Ice caps melting, ocean temperatures rising, glaciers disappearing, increase in extreme weather, decreased snow cover and earlier snow melting.
The arrows in this diagram show the flow of energy from what gets eaten to what eats it.
What is a food chain or food web?
This type of fossil fuel takes the most amount of heat and pressure to form.
What is natural gas?
This scientific principle states that matter can change form or be rearranged, but it cannot be created or destroyed.
What is the Law of Conservation of Mass
This is the number of carbon atoms that will be in the products of a chemical reaction that has reactants with 8 carbon atoms.
What is 8 carbon atoms in the products.
This is how the forest feedback loop works.
Global Warming creates warmer dryer conditions in the forest, which means tree are more susceptible to fire, disease, drought, and insect infestation. More trees die, which means less carbon dioxide is removed from the atomosphere. More carbon dioxide remaining in the atmosphere means more heat is trapped, worsening global warming.
The amount of energy passed on each trophic level on an energy pyramid.
What is 10%?
This is the relationship between global fossil fuel consumption, carbon dioxide levels, and average global temperature over the past 50 years.
Fossil fuel consumption, carbon dioxide levels, and global temperature have all risen since around 1950. (there is a direct relationship amongst all 3)
These are examples of physical and chemical properties. (list two for each)
What are
physical-color, mass, volume, density, odor, conductivity, tast, texture, shape, solubility, etc.
chemical-flammability, reactivity, corrosion, pH, radioactivity, combustability
These are the two requirements for covalent bonds to form.
What are
1. There has to be a strong enough attraction by the protons in each atom for the electrons in the other atom. (They need to be close enough)
2. There must be room for the electrons on the outer energy level of both atoms.
This is how albedo contributes to warming oceans in the Arctic.
What is water has a lower albedo, meaning it reflects less of the sun's rays than ice.
The series of events that creates dead zones.
What is.......
1. Fertilizer (nitrogen) run-off
2. Overgrowth of algae or phytoplankton.
3. Death of algae or phytoplankton.
4. Depletion of oxygen due to decomposers.
In the carbon cycle, these are the processes that occur when carbon travels from the atmosphere to land plants, then to land animals, then back to the atmosphere.
What are photosynthesis, digestion, and cellular respiration.
This is the correct arrangement of electrons into their energy levels for a neutral atom of Nitrogen, which is atomic number 7. (use a whiteboard to draw this)
What is....
The atomic number is the number of protons as well as the number of electrons. Two electrons should be placed in the first energy level and five in the second energy level.
These are three differences between complete and incomplete combustion.
What are incomplete combustion does not have enough oxygen to create as many carbon dioxide molecules, incomplete creates carbon monoxide, and incomplete creates soot (lone carbon).
These are the processes that cause the uneven formation and distribution of fossil fuels on Earth.
What is settling of dead microorganisms, burial in low oxygen and pressure to form fossil fuels. Then, tectonic plates move the fossil fuels to new locations.
