He did not use the right size battery.
He used too many pieces of wire.
He left the switch open.

Students conduct an investigation by rolling a car down a ramp covered with four different surfaces, while measuring the time it takes for the car to travel from the top of the ramp to the bottom of the ramp. The results are shown in the graph.
Which surface causes the LEAST amount of friction?
Surface W

Surface Z
A sieve is a container with very small holes in the bottom that are all the same size. What would this tool be useful for?
Sorting soil by particle size
Finding the mass of soil
Growing plants in soil
Determining soil color
Students tested the capacity of a soil to retain water. They poured 200 mL of water through a funnel holding the soil. How many milliliters of water was retained by the soil sample? (Write the number only)
(a)
Students are comparing samples of different soils to the bars on a chart their teacher gave them. What property of soil are they trying to determine using this chart?
Size
Texture
Color
Shape
Students test the amount of water retained by different types of soil. Equal amounts of soil were added to four funnels with filters, then the same volume of water was poured through each soil sample. To determine the amount of water retained by each soil sample, the student would –
Add the amount of each soil sample to the volume of water poured in.
Divide the total volume of water poured in by the number of samples.
Subtract the volume of water collected from the volume poured in.
Multiply the volume of water poured in by the number of soil samples.
Which model demonstrates a way to test properties of different soils to determine which type of soil best supports the growth of plants?
If students are investigating the texture of different soil samples, what would be the best procedure to follow?
Compare each of the samples with a color chart
Pour water into each of the soil samples
Attempt to grow plants in each soil sample
Moisten the samples and rub them with their fingers
This rock formation formed over many millions of years. What force most likely created it?
A glacier pushing rocks ahead of it
A river bringing rocks down a mountain
Wind-blow sand carving large rocks
A volcano blasting rocks great distances
Where is one most likely to find rocks that have become cool, smooth and rounded?
At the bottom of an ocean
Deep within Earth
On top of a hill
In a fast-moving river
How can a glacier change a mountain? A glacier can -
generate a volcanic eruption
cause a powerful earthquake
make a mountain grow taller
change the shape of a valley
What is the movement of sediment by wind, water or ice?
weathering
deposition
sediments
erosion
Which slow, Earth changing process is MOSTLY responsible for providing the Earth with soil?
erosion
weathering
deposition
mudslides
What is the process by which wind or water drops sediment in a new location?
weathering
deposition
sediments
landforms
Caves are large empty spaces below the surface of the earth. Which of the following processes forms caves over millions of years?
Rivers carry mud and silt and then deposit them
Water flowing underground carries away minerals
Volcanic eruptions leave behind hollow areas
Ocean currents move sediments along the beach
A farmer notices that soil on the farm has been decreasing over the past few months. What environmental factor is most likely related to the loss of soil?
Recent heavy rains
Steady increase in temperatures
Abundant crops
Decrease in temperatures

weathering
erosion
deposition
What process is the breakdown of large materials into smaller particles by water, air and other natural events?
deposition
weathering
erosion
