Metric Units
What are metric instruments used to measure length and mass? (You must have both answers correct to earn the points!)
Length - meter stick
mass - triple beam balance
What is abrasion?
Abrasion is a type of weathering caused when rocks break other rocks.
What is deposition?
The DROPPING of sediments in a new location.
Michael wonders if the type of fertilizer he uses will affect the height of his sunflower plants. He gives 5 sunflower plants “Miracle Grow” fertilizer, 5 plants “Super Grow” and 5 plants “Mega Grow.” What are some of the controlled variables in Michael's experiment?
The amount of fertilizer.
The length of time he lets the sunflowers grow.
The type of flower he is testing (sunflowers)
What are metric instruments we used to measure weight and the volume of a liquid in class? (You must have both answers correct to earn the points!)
weight - spring scale
volume of a liquid - graduated cylinder
Give an example of how abrasion might happen.
Any example that describes rocks breaking other rocks.
Waves in the ocean might smash rocks against each other.
A rock might fall on another rock.
Wind might sandblast another rock. etc.
What are the three main agents of erosion?
Water, wind and glacial ice
Rank these steps of the scientific method in the order they are usually done. (Put a 1 in the blank next to the first step, a 2 in the blank next to the second step, etc.)
_____ Analyze the data, draw conclusions, develop general theories
_____ Make an observation about something
_____ Ask a question about what you have observed
_____ Design an experiment to test the hypothesis
_____ Do the experiment and collect data
_____ Make a hypothesis to answer the question
6. Analyze the data, draw conclusions, develop general theories
1. Make an observation about something
2. Ask a question about what you have observed
4. Design an experiment to test the hypothesis
5. Do the experiment and collect data
3. Make a hypothesis to answer the question
How many millimeters are in one meter? (Don't forget to include your UNITS on this!)
1,000 mm (if you didn't say millimeters, no points for you!)
Which type of mechanical weathering happens when water gets into a crack in a rock, freezes, expands, and breaks the rock?
frost wedging or ice wedging
Rusting is an example of which type of chemical weathering?
oxidation
Michael wonders if the type of fertilizer he uses will affect the height of his sunflower plants. He gives 5 sunflower plants “Miracle Grow” fertilizer, 5 plants “Super Grow” and 5 plants “Mega Grow.” What units should Michael use to measure his plants?
meters or centimeters
What are the SI units used to measure length and mass? (You must have both answers correct to earn the points!)
length - meter
mass - gram
Which type of mechanical weathering happens when roots of a tree grow into a crack in a rock, then break the rock as the tree root gets bigger?
Biological activity
Name and describe any of the types of chemical weathering we have learned about.
Dissolution - dissolving of minerals by water
Hydrolysis - when minerals breakdown in a chemical reaction with water
Oxidation - when minerals combine with oxygen
Michael wonders if the type of fertilizer he uses will affect the height of his sunflower plants. He gives 5 sunflower plants “Miracle Grow” fertilizer, 5 plants “Super Grow” and 5 plants “Mega Grow.” What is Michael's dependent variable?
The height of the sunflower plants.
What are the SI units used to measure weight and the volume of a liquid? (You must have both answers correct to earn the points!)
weight - Newtons
volume of a liquid - liters
Which type of mechanical weathering happens when rock is under pressure with things building up on top of it, then the soil on top gets eroded away and the pressure releases?
unloading or exfoliation
What is the difference between weathering and erosion?
Weathering is the BREAKDOWN of rock material, erosion is the MOVEMENT of that material (sediments) from one place to another.
If you got this question, you can have an extra 100 points if your whole team does the "Weathering, erosion and deposition" dance.
Michael wonders if the type of fertilizer he uses will affect the height of his sunflower plants. He gives 5 sunflower plants “Miracle Grow” fertilizer, 5 plants “Super Grow” and 5 plants “Mega Grow.” What is Michael's independent variable?
The type of fertilizer
