Matter
What are the three states of Matter?
The three states of Matter are:
-solid
-liquid
-gas
What is mass? What is Weight?
What is Mass is the amount of stuff in something (in kilograms) gravity acting on an object
What is Energy? Name some different types of energy.
Energy is power that makes everything move and change.
Some different types of Energy are light energy, heat/thermal energy, sound energy, electrical energy, fuel energy, food energy, mechanical energy, chemical energy, love energy.
True or False. The world and the Universe are in constant movement.
True!
What are machines?
Machines help us perform complex tasks more easily.
Match the state of Matter to the correct characteristic.
1. Solids a. don't have a fixed shape or volume
2. Liquids b. don't have a fixed shape but have a fixed volume
3. Gases c. have a fixed shape and volume
1-C
2-B
3-A
What is volume?
Volume is how much space something takes up.
What is Motion?
Motion is movement in any direction.
What are the two types of machines?
The two types of machines are simple machines and complex machines.
Energy can cause changes of state during ______, _______, _______, and ________.
-melting
-solidification
-evaporation
-condensation
What is Density? What is the formula for Density?
Hint: the heart
What is Density is how compact an object is. The formula is mass/volume
What is an example of radiation energy?
What is The sun melting an ice cream on the side walk
What is the building block of life?
What are some examples of simple machines?
a) The wheel makes transport easier and faster.
b) The lever is a bar that rests over a pivot point and makes it easier to lift heavy object with a bar (the see-saw) or to move them around (the broom).
c) The inclined plane makes it easier to move heavy objects from a lower to a higher place.
d) The pulley makes it easier to lift heavy objects with a wheel and a rope.
e) The wedge is like a small inclined plane used for cutting. We can see it in knives and axes.
f) The screw is another inclined plane only this time it goes in circles instead of in a straight ramp and it can be used to open and closed things or to secure them tightly against another surface like when we screw a picture on the wall using a screw.
What are the general properties of matter?
Mass, volume, and density
A liter of milk and a liter of sugar take up the same space but weigh _________.
a. the same
b. differently
b. differently
What is thermal energy?
What is Energy responsible for heat?
Which organelles help transport things out of the cell?
What is the golgi body and the endoplasmic reticulum
What are complex machines?
Complex machines are a combination of simple machines put together to make more complex objects.
Ex. Scooter, bike, car, computer, etc.
What is the difference between homogenous mixtures and heterogenous mixtures?
Homogenous mixtures (salt & water) cannot be separated easily. Heterogenous mixtures (sand and water) can be separated easily.
How can we find the mass of an object when given the density and volume?
What is D*V=M
What is the law of conservation of energy?
What is Energy is not created nor destroyed but simply transferred.
What are the sphere of the planet and what do they mean?
Geo-rock and things
Hydro-water
Atmo-air
Bio-living things
What are tools?
Tools are machines that we use to make our lives easier.
Ex. scissors, hammer, screws, knives, sharpeners, etc.
