Physical Science
What are the main ways that energy can be transferred from place to place?
Sound, Light, Heat, and Electric Currents
(S.4.2)
Energy is not created or destroyed. It is moved from place to place by these methods.
In order to reduce their impact on the land, water, air, and/or other living things in the local environment, humans can...
A. Use less energy (turn off lights when they exit a room)
B. Carpool with friends
C. Reuse things when possible
D. All of the above
D. All of the above
(S.K.6)
Humans leave an impact on the environment around them, but there are ways to limit their impact. This helps our environment to stay healthy.
In the United States, there is ________ sunlight during the winter than the summer.
less
(S.1.9)
This is because our hemisphere is tilted away from the sun, resulting in less sunlight per day.
The variable that does not change in an experiment is called the ______.
Control Variable
(S.5.17)
The control variable helps to ensure that an experiment is not biased.
True or False
Stars that are farther away from Earth generally appear brighter than those that are closer.
False
(S.5.13)
Stars that are farther away from Earth usually appear dimmer while closer stars generally appear brighter.
The more force you push an object with, the ______ it will go.
Farther
(S.K.1)
By exerting more force onto an object, the object receives more energy, allowing it to go farther.
What is one species that forms a group in order to survive?
A. Bears
B. Owls
C. Wolves
D. All of the above
C. Wolves
(S.3.6)
Some species form groups to increase the chance of their survival.
What do we use fossils for?
To learn more about organisms that lived in the past and their environments.
(S.4.11)
Fossils are an amazing resource to learn more about the world before us.
True or False
The shape of an object can help its function
Ex. A wheel being round
True
(S.1.11)
Because a wheel is round, it is able to roll over different types of surfaces. Its form helps its function. This can be applied to other object as well.
All energy that animals use can be traced back to what?
A. Water
B. Sunlight
C. Food
D. None of the above
B. Sunlight
(S.5.6)
Plants use sunlight to make energy for themselves. These plants are then eaten by animals, and those animals are eaten by other animals. The energy is transferred from the sun to the plant to the animal to the next animal.
Matter is made of _____.
Atoms, or particles that are too small to be seen.
(S.5.2)
These particles are the basis of everything in the universe.
True or False
Flowers use only their stamens to reproduce.
False
(S.4.8)
The Stamen is the male reproductive organ, and the pistil is the female reproductive organ. Both are needed for flowers to reproduce.
True of False
Weather forecasting can help us prepare for severe weather
True
(S.K.8)
One of the main reasons that weather forecasts are so important is because they help us to prepare for severe weather, helping us to stay safe.
A doctor needs to take a person's temperature. They should use...
A. Their Hand
B. A Thermometer
C. Their Wrist
B. A Thermometer
(S.3.17)
There are many different ways to take a person's temperature, but out of the three provided answers, the thermometer is by far the most accurate.
True or False
All animals and plants need the same type of environment to survive.
False
(S.3.7)
Animals have different needs, meaning that they require different environments.
If ice is melted, can that change be reversed?
Yes
(S.2.4)
While not always the case, some changes caused by heating or freezing can be reversed by the opposite action.
Plants need ________ and _________ to grow.
Sunlight and Water
(S.2.5)
In order for a plant to survive, they must have these basic needs met.
What type of weather would you expect in the Sahara Desert, located in Sub-Saharan Africa?
Hot and Dry
(S.3.14)
Knowing the region allows us to predict the climate.
What are some issues that you could face when solving a problem?
Constraints on materials, time, or costs.
Specific Criteria for Success (must hold this much weight, etc.)
(S.3.16)
When attempting to solve a problem, there are often things that stand in your way, such as the ones listed above.
Humans planting a certain type of crop in order to feed themselves is an example of what?
Changing their environment to meet their needs.
(S.K.4)
By planting crops that are not native to the area, humans are altering their environment in order to fit their needs.
True or False
You can see an object in complete darkness.
False
(S.1.2)
Our eyes require at least some light to hit and object in order for us to be able to see it.
True or False
Puppies are exactly like their parents.
False
(S.1.6)
While they are similar, there are many differences, including, but not limited to, size and proportions.
What are some ways that water can be found on Earth?
A. Glaciers
B. Lakes
C. Oceans
D. Just A and B
E. A, B, and C
E. A, B, and C
(S.2.11)
Water comes in all different forms. Some can be used for drinking water and some can’t.
A scientist performs a test to find out the best way to grow a tomato plant. He puts the first plant in direct sunlight and gives it frequent water. He does the same for the second plant, but adds miracle grow to it. The first plant grows 5 tomatoes, and the second grows 10. Which method is best?
The second method (Adding miracle grow)
(S.1.12)
Although both methods resulted in plants that grew tomatoes, the second plant grew more, meaning that the miracle grow helped produce more tomatoes.
How might a shark smelling blood respond?
It might search for the source in order to feed itself.
(S.4.9)
The shark uses its sense of smell to detect a possible food source.
