Answer |
| Is the Ability to do work | Energy |
| What is matter made up of? | Atoms and Molecules |
| Atoms and Molecule moving around produce what kind of energy? | Kinetic |
| The Total Kinetic energy of particles in a substance. | Thermal Energy |
| Measure of the average kinetic energy of the particles in a substance is called... | Temperature |
| Stored energy that an object or substance has because of its motion. | Potential Energy |
| The instrument that measures temperature | Thermometer |
| Almost all substance ------ when heated and contract when cooled. | Expand |
| In Maine, a birthday balloon filled with helium and tied to a mailbox with shrink faster in January or July? | January |
| A Wooden dresser drawer may be more difficult to close during the winter or summer months? | Summer |
| Engineers design spaces between bridge sections to prevent buckling by allowing for thermal (reduction or expansion) and contraction. | Expansion |
| Unit of measure used to measure thermal energy. | Calorie |
| Certain type of sound often thought of as harsh, unwanted, or surprising. | Noise |
| A sound wave gradually ----- as its energy is used up. | Fades |
| An ---- is a sound wave that bounces back toward its source and is heard. | Echo |
| Oilbirds use ------------ to help them "see" in dark areas. | Echolocation |
| Type of echolocation that locates items underwater. | Sonar |
| Technology that uses echoes of high-frequency sound waves to "see" inside of a human body. | Ultrasound |
| The study of this helped in the development of early ideas and theories about sound. | Music |
| The waves of calm sounds are usually seen as smooth curves while the waves of harsh sounds look rough and jagged on a microphone or an oscilloscope. | Oscilloscope |
| The science of sound is called ------. | Acoustics |
| Surfaces that are smooth and hard usually absorb or reflect sound? | Reflect |
| Materials that are ------, soft or fuzzy usually absorb sound. Rough or Smooth? | Rough |
| Name the Type of Wave, Light or Sound described: Electromagnetic: Can travel though both matter and empty space. | Light |
| Name the Type of Wave, Light or Sound decribed: Faster of these two waves. | Light |
| Name the Type of Wave, Light or Sound decribed: Longitudinal Wave | Sound |
| Name the Type of Wave, Light or Sound described: Transverse Wave | Light |
| Name the Type of Wave, Light or Sound described: Mechanical wave, can travel only through matter | Sound |
| Highest point of a wave | Crest |
| Lowest point of a wave | Trough |
| Distance between 2 crests and 2 troughs | Wavelength |
| Height of a wave | amplitude |
| Number of waves that pass a certain point in one second | Frequency |
| Distance that one wave travels in one second | Speed |
| Form of wave energy | Light |
| The different colors of light are called | Visible Spectrum |
| Light always travels in a staight line. True or False | True |
| The bending of light as it passes from one medium into another | Refraction |
| Objects that do not let light pass through | Opaque |
| The colors in the visible spectrum | Roy g biv red green blue |
| The color that is seen depends on which colors of light are reflected to your eyes and which are absorbed. True or false. | True |
| When all colors of light are reflected you see white. True or False | True |
| When all colors of light are absorbed you see black | True |
| The primary colors of light are red blue and green. The colors can be used to make all other colors of light. True or False | True |
| The primary colors of light are different from the primary colors of art. True or False | True |
| Pigments are opaque substances that are used to color other materials. True or False | True |
| The attraction between particles of a substance depends on the speed at which its particles move. True or False | True |
| When the temperature of a substance increases, the speed of its particles also increases. | True |
| The slower particles move, the more attraction there is between the particles. | True |
| What Scale do scientists use to measure temperature? Fahrenheit or Celsius? | Celsius |
| Energy has many forms. True or False | True |
| What state of matter is it?Particles vibrate back and forth: great attraction between the particles. Gas, liquid or solid? | Solid |
| What state of matter is it?Particles move faster than in a solid: Less attraction between the particles than in a solid. gas, liquid or solid? | liquid |
| What state of matter is it? Particles move rapidly and cover great distances: little attraction between the particles Gas, liquid or solid | Gas |
| Movement of thermal energy from one substance to another | Heat |
| What type of heat do the following statments describe?Heat that occurs when particles bump into each other but do not change location. and Used to hear solids. Conduction, Convection or Radiation | Conduction |
| What type of heat does the following statements describe: Heat that occurs when particles carry thermal energy as they move from one place to another and Usually occurs in liquids and gases. Conduction, Convection or Radiation | Convection |
| What type of heat do the following statments describe? An important source of heat and light from the sun. and Heat that occurrs when there are no particles to carry the energy. Conduction, Convection or Radiation | Radiation |
| Amount of thermal energy needed to raise the temperature of 1 g of water 1 degree Celsius is called----- | Calorie |
