What is Stuff Made Of? �All things are made of matter. �Mass is the amount of matter in an object. �You can describe the physical properties of matter like color, smell, taste, texture, and how it conducts heat or electricity. © Hedgehog Learning

Describe the Physical Properties of Sugar �Taste? �Smell? �Texture? �Color? �Conducts Heat? �Conducts Electricity? © Hedgehog Learning

Physical Properties �Some materials will retain their physical properties even when mixed together. �Consider a mixture of sand iron filings. Does it retain its physical properties? Can you separate the mixture? How? © Hedgehog Learning

Magnetism �Magnetism is also a physical property of metals like iron, steel, and nickel. �A magnet can attract things like iron filings, paper clips, and staples, but not glass, plastic, wood, or rubber. © Hedgehog Learning

Solubility �Dissolving means to mix evenly in a liquid like water. �What are some things that dissolve in water? salt, sugar, etc. �What are some things that don’t dissolve in water? sand, metal filings, etc. © Hedgehog Learning

Temperature � Temperature measures how warm something is. The higher the temperature, the more the particles in matter move. � In science, we primarily use the Celsius scale. � Water freezes - 0˚C � Water boils - 100˚C © Hedgehog Learning

Density: Will it Sink or Float? �Density is the amount of matter in a certain amount of space. �If something has greater density than water, it will sink. �An object with lesser density than water will float. © Hedgehog Learning

Density: Will it Sink or Float? �Will a key sink or float? Does it have higher or lower density than water? �How about a block of wood? Does it have higher or lower density than water? © Hedgehog Learning

Designing an Experiment �When designing an experiment, you begin with a hypothesis, or a statement that can be tested. �For example, you may hypothesize that objects of higher mass will require more force to move them. �If this was your hypothesis, what would be your variable? What would you keep constant? © Hedgehog Learning

STAAR Review DAY 4 FORCE, MOTION, AND ENERGY TEKS 5. 6 B (R), 5. 6 C (R), 3. 6 B (S) © Hedgehog Learning

Review of Circuits � Draw a circuit that includes a battery, light bulb, switch, and copper wires. � What happens when the switch is open? � What happens if you remove the battery? � What happens if you unscrew the light bulb? © Hedgehog Learning

Light � Light is energy that can be seen. � It travels in a straight line until it strikes a mirror or travels through another medium. � Reflection is the bouncing of light off of a mirror or other shiny object. � Refraction is the bending of light when it travels through a different medium such as glass. © Hedgehog Learning

Refraction or Reflection Classify each picture as an example of refraction or reflection.

Motion and Force �Motion occurs when an object changes position due to a push or a pull. �When a change in motion occurs, a force has been applied to that object. �Work, a force applied over a distance, can be done by machines such as pulleys, swings, or wagons. © Hedgehog Learning

Examples of Work, Motion, and Force Identify the direction of forces and motion in each example below. © Hedgehog Learning

Sedimentary Rocks �Sedimentary rocks are formed by the deposition and compacting of sediment. �Sediment is material eroded from other rocks. Notice that the sediment is deposited in layers. © Hedgehog Learning

Sedimentary Rock Cycle Small rocks, sand, and pebbles are eroded and carried away by water. Sediment is deposited in a new location by the water. Deposited sediment is compacted into layers to form new rock. © Hedgehog Learning

Fossils � Sedimentary rock is perfect for capturing fossils – the imprints and remains of prehistoric organisms. � The age of fossils depends on how long ago the organism lived. Scientists use models to show time in the fossil record. © Hedgehog Learning

Fossil Fuels The energy trapped in rocks from dead organisms is called fossil fuels. Coal is formed from decayed plants that have been compacted under heat and pressure. Oil and natural gas are fossil fuels from prehistoric animals. © Hedgehog Learning

Energy Sources �Fossil fuels are considered nonrenewable resources. They cannot be replaced when they are used which is why we should practice conservation. �Renewable resources are energy sources that are always available. They include solar, wind, geothermal, hydroelectric, and biofuels. © Hedgehog Learning

Renewable Resources Name these renewable resources and describe how they can be used to produce energy. © Hedgehog Learning

Landforms � Weathering from wind, water, and ice can create magnificent landforms on Earth! River deltas are triangular formations caused by the depositing of sediment in the river when the flow of water slows down. The sediment is the result of erosion upstream. © Hedgehog Learning

Landforms Canyons are formed by water cutting through the rock and carrying away sediment. Over time, the river or stream carves a deep formation in the rock. © Hedgehog Learning

Landforms Sand dunes are formed from wind gusts that carry sediments in the air and deposits the grains of sand on top of one another until a large hilllike structure is formed. © Hedgehog Learning

Landforms Glaciers are large sheets of ice that move slowly over time. Their large size and weight can carve smooth hills and valleys in the landscape. Valley carved by glacier

Rapid Changes in Landforms �Sand dunes, canyons, deltas, and glacier valleys are formed slowly over time. �Sometimes, the Earth can experience rapid changes from mudslides, earthquakes, and volcanoes. © Hedgehog Learning
