1 Increase Decrease (Reduce) State of Matter Property Density Energy Temperature To become bigger or make bigger the amount or size of something. To become smaller or make smaller the amount or size of something. For example, if the grass that crickets eat dies, the population of crickets would likely decrease. The form something can take. The most common states of matter are solid, liquid, or gas. A characteristic of something, such as texture, shape, color, odor, size etc. How tightly or loosely packed the molecules of an object, liquid or gas are. For example, a ping-pong ball and a golf ball may have the same volume/size, but the golf ball is denser. The ability to do work (like moving an object, or lighting a bulb). The main source of energy is the Sun. Chemical energy is found in food and batteries. An example of mechanical energy is chewing or moving. Light and heat energy is in the Sun and light bulbs. Sound energy is produced when you speak or play an instrument. How hot or cold something is. The tool to measure Organism Length Width Diameter Mass Volume Vibration Any living thing. All organisms grow, reproduce (have babies) and die. How long something is (measured in centimeters (cm) or inches with a ruler or meter tape). How wide something is (measured with a ruler or meter tape in cm or inches). The width of a circle (measured with a ruler in cm or inches). The amount of matter in an object and can be measured using a scale or a balance. The unit of measurement is the gram ( g ). How much space something takes up. The tools to measure volume are a graduated cylinder, a beaker, or a measuring cup. The main units of measurement are milliliter (ml) or liter (L). Movement back and forth, which causes sound energy. When

2 Gravity Lubricant Work Insulators temperature is the thermometer, and the unit of measurement is degrees Celsius or degrees Fahrenheit. Water freezes at 0 degrees Celsius and boils at 100 degrees Celsius. A force that pulls objects toward the center of the Earth. Something that decreases/reduces friction, like water on a water slide, or the slime that helps a snail glide. In science, work is done when you apply force to something causing it to move. Materials that block the flow of electricity (anything non-metal). Examples include rubber, glass, wood, plastic, paint etc. Pot handles are often plastic because plastic doesn t conduct heat like metal. Friction Simple Machines Conductors Force of Attraction you hit a tuning fork, it makes a sound. A force that pushes in the opposite direction an object is moving. Something smooth has less friction than something rough. Concrete has more friction than ice, and that s why you slide less on concrete. Something that helps us use less force to do work. Examples are pulleys, levers, inclined plane (ramp), and screws. Simple machines use mechanical energy to move objects. Materials that transmit/carry the flow of electricity. All metals are conductors. Examples of object that conduct electricity include wires, paper clips, coins, and many other metal objects. How much pull there is between two magnets. As you increase the distance between two magnets, the force of attraction decreases. This just means that if you take two magnets and move them further apart, they attract each other less.

3 Iron Circuit Contracts Evaporation Precipitation Groundwater Structure Function The main metal that attracts magnets. Metals such as copper and aluminum do not attract magnets, while nickel does a tiny bit. A closed path around which electricity can flow. Electricity only flows in a closed circuit (when metal is touching metal). An open circuit breaks the flow. Gets smaller, the molecules get closer together. When a liquid turns into a gas. For example, when water turns to vapor When the water in the clouds gets too heavy and falls back down as rain or snow Water under the Earth s surface Part of something. For example, the structures (parts) of the plant are the roots, stem, and leaves. The job or purpose of something. For example, the function (job) of a plant s roots is to take in water and nutrients, and to Chemical Energy Expands State of Matter Condensation Runoff Water Cycle Germination Habitat The kind of energy you find in batteries which then flows through wires in the form of electric energy, and becomes heat energy and light energy in the bulb. Gets bigger, the molecules get further apart. Refers to solid, liquid or gas. In the case of water, is it ice when solid, water when liquid, and water vapor when gas. When vapor/gas turns back to liquid. This is how clouds are formed. Excess water that flows down the surface of the land. The Sun gives energy to the water cycle by evaporating water from puddles, lakes, and oceans, which then goes up into the clouds (condensation), and falls back to the earth (precipitation). When a seed starts to grow. Another word for it is sprouting. The natural home or environment of an organism (plant or animal).

4 Inherited Trait Behavior Life Cycle of Insect Seed Dispersal Predators Food Chain Primary Consumer Decomposers anchor the plant into the ground. Something that you get from your parents when you re born. Eye color is an example. Something a person or an animal does. A learned behavior is something you learn to do. Egg Larva Pupa Adult. Example: Egg Caterpillar Chrysalis Butterfly. When seeds are spread around. They are moved by wind, running water, sticking to animals fur, or by passing through an animal s digestive system. Animals that hunt other animals for food. If a cat hunts a mouse, the cat is the predator and the mouse is the prey. A series of organisms that depend on eating each other for survival. The source of energy for a food chain is the Sun. Sun Producer (Plant) Primary Consumer Secondary Consumer Tertiary Consumer An animal that eats plants. Animals that break down dead plants and animals by eating them. Earthworms and flies are examples of decomposers. Learned Trait Offspring Life Span Migration Prey Producer Secondary Consumer Competition Something you learn, and are not born with, like learning to read. Someone s children. For example, you are your parents offspring, a puppy is a dog s offspring. The length of time that a person or an animal lives. When animals, such as birds, leave a habitat for another, usually for a season and then return. Any animal that is hunted by other animals Plants are producers because they produce (make) their own food and oxygen using light, water and carbon dioxide (CO2) in a process called photosynthesis. An animal that eats the primary consumer. Something that happens when different animals need the same resources to survive. For example, if there is a limited amount of food, an animal needs to try harder to

5 Adaptation Deposition Revolution Pollution An adaptation is a change by which an organism (living thing) becomes better suited for its environment. Examples of adaptation include a snail s shell (which helps protect it from predators), an anole s camouflage (it turns brown or green to blend in to the background, which protects them from predators), and a bear hibernating (to adapt to environmental changes like the cold weather, and a decrease in food). Coloration is the natural color and design on an animal, such as the colors of a bird s feathers, which can help it attract a mate. When land that was taken away from somewhere, is added to somewhere else. Circling of the Earth around the Sun, takes one year. The presence of a harmful/unhealthy substance (thing). For example, a factory can produce pollution in the air and in water. Erosion Sun Rotation Natural Resource get that food before the others. When water or wind takes away land (soil or rock) from somewhere. A star that is the main source of energy for life on Earth. Spinning of the Earth, takes one day, causing the Sun to rise and set. Something found in nature that can be used by people.
