NOS Variables
What is the Independent Variable?
The variable the experimenter changes
The variable that is different between groups.
Identify the independent variable in this experiment?
Mary and John want to test the effects of acid rain on plant growth. They have 4 groups of plants and they give each group a different amount of acid rain. Each group gets the same type of acid rain, the same type of soil, and the same type of plant.They water the groups twice a week every for 8 weeks. At the end of each week they measure the plant heights.
The IV= different amount of acid rain
Igneous
Metamorphic
Sedimentary
What are the three surface events?
Weathering
Erosion
Deposition
This type of land form resembles piles of sand and is usually found at beaches in Florida
Dunes
What is the dependent variable?
The variable that "Depends" on the independent variable.
This is the Data that is collected. The output variable.
Identify the dependent variable in the experiment below:
Mary and John want to test the effects of acid rain on plant growth. They have 4 groups of plants and they give each group a different amount of acid rain. Each group gets the same type of acid rain, the same type of soil, and the same type of plant.They water the groups twice a week every for 8 weeks. At the end of each week they measure the plant heights.
The DV = plant height
What type of Rock is made from magma cooling?
Igneous Rock
Which surface event involves moving or transporting weathered rock particles?
Erosion
This type of landform can usually weather and then erode rock really far distances
River
What is/are the constant(s) in an experiment?
All things that are kept the same in an experiment.
Identify the Independent variable below:
Ms. Tyson is testing her hypothesis that candy will make her students get higher test grades. She offers half of her students a bag of candy if they get an A or B on the test. She doesn't offer the other half of the students any candy. The students all have the same teacher, the same class, and will take the same test.
The IV = whether or not the students were offered candy
What conditions are needed to make metamorphic rock?
High Heat and High pressure
Weathering of rock by force or movement.
Can be by wind, water, or ice
When a river eventually opens up to a large body of water, a massive amount of sediment can settle/deposit at the end. What new landform is formed?
A delta
Identify the constants in this experiment:
Mary and John want to test the effects of acid rain on plant growth. They have 4 groups of plants and they give each group a different amount of acid rain. Each group gets the same type of acid rain, the same type of soil, and the same type of plant.They water the groups twice a week every for 8 weeks. At the end of each week they measure the plant heights.
The constants are= type of acid rain, type of soil, and type of plant
Identify the Depend variable in the experiment:
Ms. Tyson is testing her hypothesis that candy will make her students get higher test grades. She offers half of her students a bag of candy if they get an A or B on the test. She doesn't offer the other half of the students any candy. The students all have the same teacher, the same class, and will take the same test.
The DV = test grade
What is the settling of rocks at the bottom a river an example of?
Deposition
This landform is a frozen moving mass that can be responsible for weathering and eroding rock. It also effects sea levels!
A glacier
Identify the constants in the following experiment:
Ms. Tyson is testing her hypothesis that candy will make her students get higher test grades. She offers half of her students a bag of candy if they get an A or B on the test. She doesn't offer the other half of the students any candy. The students all have the same teacher, the same class, and will take the same test.
The constants = same teacher, same class, same test
Which of the following is NOT a model?
A) a graph of mountain height over time
b) a drawing of how the coast line has changed
c) a robot creating a new car
d) a 3d recreation of earth
What type of rock is responsible for forming rock layers that scientists can use for relative dating?
Sedimentary Rock
Acid rain falling on the top of a mountain and weathering the rock over time is an example of?
Chemical weathering
This landform changes often overtime and is where land meets ocean water.
A coastline
