Nature of Science
Hannah and Avery are working on a project to create a model of their school. What limitations might they face while creating this model?
They cannot include all the details of the school building in their model
Some accuracy of the school building is lost to make the model simplistic enough to communicate ideas
Their model is not an exact representation of the school building
You are standing in front of a calm lake on a sunny day, looking at yourself on the water's surface. Explain and draw what kind of light behavior demonstrates this concept of why you can see a clear image of yourself in the lake.
When a wave strikes a surface and bounces off it is called a reflection. (Show drawing of reflection using an arrow)
Which type of electromagnetic radiation has a higher frequency than microwaves but a lower frequency than ultraviolet waves?
Infrared waves
Visible Light
What is the best description of the outer core?
It is the liquid inner layer of Earth, made of metals at extremely high temperatures.
If an object is moving to the right, what will happen if a greater force is applied in the opposite direction?
The object will slow down and then move in the opposite direction.
This kind of investigation shows a student observing plant and animal cells under the microscope and using a Venn diagram to compare what they observe.
Comparative
How does visible light interact with a red leaf?
Red light is reflected while all other colors are absorbed.
How do the wavelengths and frequencies of radio waves differ from infrared waves?
Radio waves have longer wavelengths and lower frequencies than infrared waves.
Compare Earth’s inner core and mantle.
The inner core is thinner than the mantle.
Logan is pushing a cart with 75 N of force. If Gabriella wants to help Logan demonstrate balanced forces, what should she do?
Push with a force of 75 N in the opposite direction of Logan.
Lilly was trying to explain to her friend the difference between a theory and a law in science. She used the theory of plate tectonics and the law of superposition as examples. Lilly explained the difference by using non-scientific language. Which statement could Lilly use to correctly describe the difference between a theory and a law in science?
A theory explains a natural event, while a law describes it.
As light moves through the air and enters the water of a lake how will it behave?
Light will slow down as it moves from the air into the water, causing it to refract.
What are some examples of common usages for infrared radiation?
Thermal Imaging
Remote Controls
Night Vision in Cameras
Electric Heaters
Two students discuss the processes forming the rocks near mountains and lakes. How are each of these rock types formed at these locations?
Metamorphic rock is formed by the heat and pressure of tectonic plates, which push it up to form mountains. Rivers deliver weathered rocks into lake beds, forming sedimentary rock as more layers are added.
Create a statement describing the forces acting on an object in motion.
To cause a change in speed or direction, an unbalanced force must be applied to an object.
Alisha's science teacher asked each student to create a model of the Earth's tectonic plates. Alisha decided to use a hard-boiled egg. Part of the assignment required her to describe the benefit of the model they chose. What would be the best description to accurately describe her model's benefit?
The cracks on the shell represent the tectonic plate boundaries.
In what order will the speed of sound waves travel from fastest to slowest, in different states of matter?
solid, liquid, gas
List the correct order of the electromagnetic spectrum from shortest to longest wavelength.
Gamma rays, X-rays, Ultraviolet light, Visible light, Infrared radiation, Microwaves, and Radio waves.
Which of the following events must occur to transform sedimentary rock into igneous rock?
Tectonic plates push against each other, driving sedimentary rock under the Earth's surface, where it melts into magma and turns into igneous rock as it cools.
A car traveled 90 km from Jacksonville to Daytona in 2 hrs. What is the average speed the car traveled?
45 km/hr
A team of biology students investigated to test how four different solutions affect the volume of a raw chicken egg. Two identical raw chicken eggs were placed into four containers, each containing a different solution. After 24 hours, the volume of each egg was measured and recorded. What is the test variable (independent variable) in this investigation?
type of solution in the container
Describes how light behaves when sunlight strikes the window of a house.
The light wave slows down as it travels from a gas to a solid.
Describes the characteristics of white light.
White light is composed of a spectrum of different colors.
About 10,000 earthquakes occur in the California area each year. Describe why earthquakes are a common occurrence in California.
The two plates form a transform boundary because earthquakes are caused by plates sliding past each other.
Create an example of an unbalanced force acting on an object.
A ball is hit by a bat.
An example should include an object moving due to force.
