Heat Energy Day 1 Vocab and Matter Unit 4 - 5th Grade Science
Setting Up Your Journal Title Page “Heat Energy” should be written on the page in cool, fire-style font, and you should include illustrations that are labeled (which will need to be colored in)
Table of Contents and Essential Questions Page 3 – Essential Questions Pages 4-5 – Vocabulary Essential Questions How do interactions of matter affect us? How does heat move from one place to another?
Vocabulary Energy – the ability to do work Heat Energy- is the energy moving particles have. Thermal Energy - heat energy Mixture – a combination of 2 or more kinds of matter Density – the concentration of matter in an object Volume – the amount of space an object takes up Weight – a measure of the pull of gravity on an object
Vocabulary Continued Temperature- measure of the average energy of moving molecules. Thermometer- measure temperature. Conduction- transfer of heat from a warmer object to a cooler object. Conductors- materials that conduct heat well. Insulators- materials that do not conduct heat well. Convection – movement of heat energy through liquids and gases in currents. Radiation – heat energy moves through space.
Vocabulary Continued Properties – an object’s specific characteristics Reactivity – the ability of a substance to react chemically Combustibility – the chemical property of being able to burn
Matter Solids, liquids, and gases are made of molecules. These molecules are always moving. How fast these molecules are moving depends on how much energy they have. When heat is added to matter, the molecules move faster -the temperature goes up. When heat is taken away, the molecules move slower – the temperature goes down.
Matter continued A substance that has mass and takes up space 4 states of matter: solids, liquids, gasses, and plasma Energy is what changes a phase of matter.
