Sustainability and DOPPHAE
Define climate change
long term change in temperature, precipitation and other atmospheric patterns on earth
Define catalyst
A substance that helps speed up a reaction
Purpose summary and materials for waves lab
Purpose: To follow the pattern of waves through various objects
Summary:Larger surface area generally transmits more waves
Materials:Plastic ruler, wooden stick, sponge, cloth and a rubber band
How does a balanced Force affect an object
Object stays at rest
If Von pushed a sled down hill with more force than the amount of friction that would otherwise slow it down that would be an example of
Kinetic energy
Define overexploitation
When plant and animals are taken from their habitat, decreasing the population.
what happens when concentration goes up
What is if concentration goes up the rate of reaction goes up because there are more reactants to react with
Purpose summary and materials for Mirror lab
Purpose:To observe how an object appears in a mirror
Summary: Objects appeared flipped and inverted
Materials: Mirror, Index card, writing utensil and ruler
Does Light need a medium to travel through
No not necessary
More mass=
More kinetic energy
Define habitat fragmentation/destruction
What is when a part/all of an ecosystem/habitat is removed and built on.
How does surface area influence the rate of reaction
What is gives more space for particle collision
List the three main types of heat flow
Convection Conduction Radiation
Double or nothing!
1. Define Kinetic energy
2. Define potential energy
1. Energy of motion
2. Stored energy based on position
What is the key factor for Kinetic energy
How does carbon footprint affect the environment
What is it contributes to climate change by trapping heat in the air along with many other greenhouse gases
Define inhibitor
What is any substance that slows the rate of a reaction
Double or nothing Get two right you get 800 points
Get one right and one wrong or both wrong no points
A. List the Purpose, Summary, and independent and dependent variables of the Heat Flow Lab
B. List the Purpose, Summary, and independent and dependent variables for the Steel Wool Lab
A. Purpose:
To compare the amount of time required for an ice cube to melt in a person’s non-dominant hand.
Summary: Conduction was the main source of heat in this lab
Ind. Var. The person heat in their hand
Dep. Var The amount of minutes needed for the ice to melt
B
Purpose:
To observe the reaction between steel wool, vinegar and oxygen in the air.
Summary:
This was shown as an example of an exothermic reaction due to the fact that heat was released
Ind. Var. The solution of vinegar Dep. Var. How much it changes the appearance of Steel Wool
Define unbalanced force
When the forces acting on an object are not equal and opposite, this will cause a change in the object’s motion.
What is the key factor of Potential energy
The key factor for potential energy is its position/location or state.
Define Eutrophication
What is a form of water pollution caused by humans
How does temperature act like a catalyst in a reaction.
What is If temp is raised it speeds up the reaction by giving particles more energy to collide.
What is the type of reaction in the steel wool lab, Define it
The type of reaction is an exothermic reaction
An exothermic reaction is a type of reaction where energy is released
List the type of wave for each
Light
Sound
Light: Electromagnetic wave
Sound: Mechanical wave
Effect of an unbalanced Force
The object stays at rest or continues moving at a constant speed in a straight line with no acceleration.
