Matter
A cup of water is left out overnight and is empty the next morning. What happened to the water?
What is- it changed states of matter and evaporated. It changed from liquid to gas.
A pan is placed on a hot stove tops and heats up. What type of heat transfer is this?
What is conduction?
What is an example of a terrestrial ecosystem?
What is an example of an aquatic ecosystem?
1. What is the deciduous forest, grasslands, desert, rainforest
2. What is any body of water, i.e. ocean, pond, lakes, swamp, estuaries
What are Newton's 1st and 3rd laws of motion?
What is-
1.Inertia
3. For every force, there is an opposing force acting on it
When matter changes form, what type of change takes place?
What is a physical change?
A bike is left out in the rain and rusts, what type of change has taken place?
What is a chemical change?
The sun warming the water on earth's surface is what type of heat transfer?
What is radiation?
How would a decrease in decomposers affect an ecosystem?
What is- it would affect the quality of soil?
A tennis ball moves 6 feet per second. If a player is trying to calculate the distance, what does she need to know?
What is the total time the ball traveled?
What are examples of abiotic factors in an ecosystem?
What are non living things? Such as sun, rocks, soil, water, weather, temperature, etc.
I have a sheet of paper that weighs 10 g. I rip it into 5 pieces. What is the combined weight of the pieces?
What is 10 g?
A current of warm air rises while cool air sinks is what type of heat transfer?
What is convection? (A convection current)
grass > rabbit > fox
Above is a simple food chain. Removing which component would be most detrimental and why?
What is - removing the grass because it is the producer that feeds the rabbits which are food for the foxes. Without it, the rabbits can't eat so they will die then they will not be able to feed the foxes so they will also decrease in population.
If ball is rolling downhill, what is the force that causes it to slow down?
What is friction?
The 5th graders were playing a game of tug-of-war. The class was divided equally with half the class on one side of the rope and the other half on the opposite side. For 5 minutes the students pulled and pulled but neither side could pull the flag to one side or the other. Why is this?
What is- the forces were balanced?
I have 2 slices of cheese that are 15g each. I melt them in the microwave. What is the mass of the liquid cheese?
What is 30g?
Why do your hands not burn if you hold a hot beverage in a styrofoam cup?
What is- because styrofoam is a good insulator therefore it keeps the heat contained inside the cup.
Provide an example of a terrestrial organism relying on an aquatic organism for survival?
Answers may vary.
What is a bird eating a fish out of a body of water?
A ball is rolling on a field. How would an increase in friction affect the ball?
What is the ball would slow down?
An object that transfers heat easily
What is a conductor?
How do I know a physical change has taken place?
What is- an object is the same substance but it could be in a different form or have a different shape. (For example, cutting a sheet of paper)
A light bulb glowing is what type of heat transfer?
What is radiation?
What type of wildlife and vegetation can be found in a grassland?
What is grass and lions, zebras, tigers, rhinos, etc.
An object at rest has a lot mass, therefore it has a lot of inertia. How does this affect the motion of the object if I want to put it into motion?
What is - a lot of force would be needed to move an object with a lot of inertia?
Which ecosystem is most likely where the ocean meets a body of fresh water?
A) a lake
B) a pond
C) an estuary
D) a swamp
What is C) an estuary because it has BRACKISH waters (a mix of saltwater and freshwater.. a small amount of salinity.)
