A pair of tight-fitting eyeglasses, often tinted or having side shields, worn to protect the eyes from hazards such as wind, glare, water, or flying debris. Unit - Magnets an object that pulls on some metal objects Unit Motion push or pull the act of changing place or position a repeating event where an object is placed to move from one place to another with the same part of an object touching the surface to move from one place to another by turning over and over repeating motion that turns around a point 1

2 condensation cooling energy evaporation freezing heat energy heating melting thermometer light energy dim bright sound energy vibrate matter physical property shape mass texture flexibility state of matter solid liquid Unit - Heat the change from a gas to a liquid to make less warm the ability to cause movement or create change the change from a liquid to a gas to change from a liquid to a solid by losing heat the energy of moving particles to make warm or hot to change from a solid to a liquid by adding heat how hot or cold something is a tool used to measure Unit - Light energy that you can see less light more light Unit - Sound energy you can hear to move back and forth quickly Unit - Properties of Matter anything that has mass and takes up space attributes that can be observed and measured the outward form of an object the amount of matter in an object how a substance feels ability to bend a form that matter can take such as solid, liquid, or gas a state of matter that has a definite shape and volume a state of matter that has a definite volume but takes the shape of its container 2

3 property combine folding sanding structure condensation evaporation model water cycle air cloud rain gauge season thermometer weather wind wind vane moon star Sun mineral property rock texture Unit - Changing Matter an attribute that can be observed and measured to put together to bend so that one part covers another the smoothing of a surface a collection of parts held together Unit Water Cycle the change from a gas to a liquid the change from a liquid to a gas something that helps us learn about the way it works water or ice that falls to Earth in the form of rain, snow, sleet, and hail the movement of water between the air and Earth Unit Weather gases that surround the Earth a clump of tiny water drops that hangs in the air a repeating event water that falls from clouds in the sky, includes rain, snow, and hail a tool used to measure how much rain has fallen a time of year that shows a certain weather the measure of the amount of heat a tool used to measure a description of the outside air in a certain place at a certain time moving air a tool used to show which direction the wind is blowing Unit Objects in the Sky a natural object in space that orbits around a planet events that repeat over and over again a big ball of hot gases that gives off light the star at the center of our solar system Unit Rocks a solid material found in nature that has never been alive characteristic of a material that helps to identify or classify something a solid material made up of minerals the appearance and feel of a substance 3

4 freshwater natural resource saltwater water conservation natural resource manmade resource recycle reuse soil animal environment basic needs factor behavior migration hibernation environment factor basic needs behavior dormancy plant Unit Water water that does not have salt in it something found in nature that people can use water that has salt in it a clear liquid that has no color, taste, or odor Unit Natural Resources the saving of resources by using them carefully materials in nature that people use to make things materials that people make to collect things so they can be remade into new things to use things again made of broken down rock and once living things Unit Animals a living thing that can move on its own, eats plants and other animals for food and produces offspring the living and nonliving things in an area where an organism lives something an organism must have to survive and produce offspring a cause of something changing a response to a change in an organism s environment that helps it survive when an animal moves to a new environment because the current one is difficult to live in a deep sleeplike state when an animal s, heart rate, and breathing slow down water or ice that falls to Earth in the form of rain, sleet, snow, or hail Unit Plants the living and nonliving things in an area where an organism lives a cause of something changing something an organism must have to survive and produce offspring a response to a change in an organism s environment that helps it survive when plant growth is slowed down or stopped a living thing that cannot move from place to place on its own, makes its own food, and produces offspring water or ice that falls to Earth in the form of rain, sleet, snow, or hail 4

5 molt larva life cycle nymph pupa adult food chain interdependence Unit Life Cycles the process of shedding the outer skin of an insect as it grows hatches out of an egg, often worm-like series of stages that an organism passes through as it is born, grows, and dies hatches out of an egg, looks like a smaller adult but does not go through a pupa stage occurs as the larva changes completely inside a cocoon fully developed and mature Unit Interdependence transfer of energy from one organism to another need for another living thing and the environment 5
