Solid State of Matter These crystals of the mineral pyrite are a good example of a solid. Click on image for full size Courtesy of Corel Solid is one of the four common states of matter. The three others are gas, liquid, and plasma. There are also some other exotic states of matter that have been discovered in recent years. Unlike liquids and gases, solids have definite shapes. The atoms or molecules in a solid are packed together much more tightly in a solid than in a gas or a liquid. Solids are usually much more dense than liquids and gases, but not always. Many solid materials will melt when heated. Crystals, wood, rocks, most metals, and glass are all examples of common solids. Shop Windows to the Universe Science Store!

The Science Spot Physics for Kids: Properties of Waves Science >> Physics for Kids There are many properties that scientists use to describe waves. They include amplitude, frequency, period, wavelength, speed, and phase. Each of these properties is described in more detail below. Graphing a Wave When drawing a wave or looking at a wave on a graph, we draw the wave as a snapshot in time. In this picture you can see that the highest point on the graph of the wave is called the crest and the lowest point is called the trough. We can determine a number of wave properties from the graph. Amplitude The amplitude of a wave is a measure of the displacement of the wave from its rest position. Amplitude is generally calculated by looking on a graph of a wave and measuring the height of the wave from the resting position. The amplitude is a measure of the strength or intensity of the wave. Wavelength The wavelength of a wave is the distance between two corresponding points on back-to-back cycles of a wave. Frequency and Period Speed or Velocity of a Wave

Fifth grade Lesson States of Matter Part 1 | BetterLesson Inquiry Based Instructional Model To intertwine scientific knowledge and practices and to empower students to learn through exploration, it is essential for scientific inquiry to be embedded in science education. While there are many types of inquiry-based models, one model that I've grown to appreciate and use is called the FERA Learning Cycle, developed by the National Science Resources Center (NSRC): 1. Focus 2. 3. 4. A framework for implementation can be found here. I absolutely love how the Center for Inquiry Science at the Institute for Systems Biology explains that this is "not a locked-step method" but "rather a cyclical process," meaning that some lessons may start off at the focus phase while others may begin at the explore phase. Unit Explanation In this unit, students will begin by exploring the properties of matter. Summary of Lesson Today, I open the lesson by discussing the three states of matter. Next Generation Science Standards 5-PS1-1. 5-PS1-3. Crosscutting Concepts

ScienceGeek.net - Support for High School Science Physics for Kids: Basics of Sound Science >> Physics for Kids Sound is a vibration, or wave, that travels through matter (solid, liquid, or gas) and can be heard. How does sound move or propagate? The vibration is started by some mechanical movement, such as someone plucking a guitar string or knocking on a door. This causes a vibration on the molecules next to the mechanical event (i.e. where your hand hit the door when knocking). When these molecules vibrate, they in turn cause the molecules around them to vibrate. Sound must travel through matter because it needs the vibration of molecules to propagate. Speed of Sound The speed of sound is how fast the wave or vibrations pass through the medium or matter. In dry air, sound travels at 343 meters per second (768 mph). What is the Sound Barrier? When airplanes go faster than the speed of sound (also called Mach 1), it's called breaking the sound barrier. When planes break the sound barrier they also create something called a sonic boom.

Fifth grade Lesson Physical Changes Versus Chemical Changes The Focus of the Investigation: After our foldable is created, it is time to investigate some changes to practice identifying them as physical changes or chemical changes. The students get very excited about some of these activities so it is important to help guide them to help them focus on what is most important, observing the changes that are occurring and watching for one of the indicators listed in the foldable. The Physical and Chemical Change Investigation Sheet that I use for this lesson has students identify properties before and after to help them notice these changes. Investigating in Small Groups: We do the rotations as a class, but each group completes the activities and investigation sheet together. Next, we move to the station 1 activity: Origami. We move on to station 2: Lava Lamps. Station 3 is building a boat out of an 10" x 10" square of aluminum foil. After boats are built, we move on to station 4: Balloon Blow Up. Our final station is station 5: Glue Bouncy Balls.

What is Matter | Matter Facts for Kids Some substances, like glass and water, allow light to pass through them. These substances are called transparent or see-through. The matter is still there, even though it can be hard to see. Humans are very good at changing matter to make things we can use. Gases Gases Gases such as air are the lightest state of matter. Gases › Solids Solids Solids, such as wood and stone, have a fixed shape that is difficult to change. Solids › Liquids Liquids Liquids such as water can flow freely, changing their shape. Liquids › Some matter is bound up in living creatures, such as animals and plants. Earth is mostly made up of nonliving substances such as rock and metal. Changing states Changing states Matter can come in different forms, or states, such as solids, liquids, and gases. Changing states › Atoms › All matter is made up of tiny, tiny particles called atoms. Atoms › Inside an atom › Atoms can be broken down into even smaller particles. Inside an atom › Molecules › Molecules ›

Eighth grade Lesson Eliciting Student Ideas: What is Heat? What is Temperature? This starts a series of lessons that introduce students to Heat and Temperature. I teach these in the context of a my unit on Changes in Earth's Atmosphere in order to apply the understanding of heat transfer on atmospheric phenomena as opposed to stand alone physical science lessons. This set of lessons gets students thinking about how heat is transferred through conduction, convection, and radiation. You begin with an elicit of student's ideas on heat and temperature followed by engaging them in discussion of their ideas. First up is a lesson from the American Chemical Society, where students complete an activity in which heat is transferred from hot water to metal washers and then from hot metal washers to water. A lab modeling the Greenhouse effect looks at heating of soil and water with and without an "atmosphere" as part of an exploration of heat transfer by radiation. Science and Engineering Practices Planning and Carrying Out Investigations Engage in Argument From Evidence
