Science Test Energy

5th Grade

QuestionAnswer
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
