5th Grade Science Worksheets and Study Guides
The big ideas in Fifth Grade Science include learning about the life, earth, and physical sciences by exploring them within the framework of the following topics: “Ecosystems: Terrestrial and Aquatic” (characteristics and interactions); “Landforms and Oceans” (natural processes and the ocean floor); “Properties of Matter” (mixtures and solutions); and “Forces and Motion” (position, direction, and speed).
Atmosphere & Weather
Planet Earth (the planet on which we happen to live) spins on an imaginary line called an axis. One spin around on its axis is called a revolution. As the earth rotates, the areas facing the Sun slowly change, and that means the time of day and the temperatures change.The sun is the main energy supply for the water cycle.

What are the Four Most Influential Air Masses that Affect the Weather in North America? What is needed for a thunderstorm to occur? Thunderstorm key ingredients: Moisture, Instability and Uplift. What is a hurricane? What is a tornado? What is climate? Climate Zones: Polar zone, Temperate zone, Tropical zone. The location of the zone determines its climate.

The Rock cycle, Volcanoes. How do Earthquakes happen? Read more...iWorksheets: 5Study Guides: 1Vocabulary: 4 Minerals are solid elements formed naturally in the Earth’s surface. Every mineral has a unique chemical composition – a mix of the chemicals that formed it. Rocks are made up of minerals, sometimes more than one kind of mineral! Read more...iWorksheets: 3Study Guides: 1Vocabulary: 2 All planets in our solar system rotate and they all revolve around the Sun. Inner planets: Mercury, Venus, Earth. Outer planets: Jupiter, Saturn, Uranus, Neptune. Comets are made of ice and rock. They have four parts: a nucleus which is the solid portion of the comet and is made of dust and ice, a coma which is a cloud of dust and evaporated gases, an ion tail and a dust tail.

A renewable resource is a resource that can be naturally restored or at least replenished as it is needed: The power of WIND, the power of WATER, the power of the SUN, Geothermal energy (heat from the earth), the Energy of TRASH. Fossil fuels - Crude Oil, Coal, Natural Gas - are nonrenewable resources. These types of resources take much longer to replace than most societies can wait. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 2 What is motion? Motion is the process of an object changing its place or its position. Motion is not speed. Speed is the rate an object changes position. Newton's law of motion. Read more...iWorksheets: 5Study Guides: 1Vocabulary: 2 Sound is a type of energy that travels in waves which are caused by vibrations. Characteristics of Sound. Vibrations: movements made rapidly back and forth. Sound Waves: an invisible transfer of sound energy as it travels away from the energy source. Wavelength: the distance between a point on one sound wave and a similar point on another sound wave. Frequency: The number of vibrations in a period of time is called the frequency of a vibration. Volume: The loudness or quietness of a sound is its volume. Read more...iWorksheets: 5Study Guides: 1Vocabulary: 2 Science process skills include observing, classifying, estimating, measuring, inferring, predicting, creating graphs, and developing models. Identify Dependent and Controlled Variables: A dependent variable is the variable that is being observed during an experiment. A control variable is the part of an experiment that you do not make any changes to which you can use to compare the other parts of your
experiment to. Read more...iWorksheets: 3Study Guides: 1 Matter & its Interactions
Elements are a basic (simple) kind of matter. They can’t be broken down into simpler parts and still keep their properties because they are in the simplest form. A solute is the substance that is dissolved in the solvent. Solubility refers to the ability of one substance to dissolve into another substance. Read more...iWorksheets: 5Study Guides: 1Vocabulary: 2 What is matter? Matter is anything that takes up space and has mass. Kinetic energy is energy that is happening now; it is energy in motion. Potential energy is energy that is waiting to happen; it is stored energy. How does heat get transferred: By conduction, by convection and by radiation. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 2 An Acid is a type of sour substance. Examples of acids are lemon juice and vinegar. A base is a type of bitter substance. A base dissolved in water is called a basic solution. Examples of a base substance are soap and baking soda. Scientists use a variety of pH indicators to determine which substances are bases and which are acids. Read more...iWorksheets: 5Study Guides: 1Vocabulary: 2 A chemical change is a change in which one kind of substance is changed into a different kind of substance. Chemical changes produce substances that were not there when you started. You can’t reverse or undo a chemical change. The substance or object involved in physical change is the same before and after the change (unlike a chemical change). The change is not permanent and can be undone.

The molecules in liquids are not as close as those in solids; they have a little more room to move around. The molecules in gases are far apart. Gases can fill any size room or any size container.

FreeHere are some examples of the systems that animals and humans have in common: Integumentary system, Muscular system, Endocrine system, Nervous system, Circulatory system, Respiratory system, Digestive system, Excretory System, Reproductive system, Immune system, Skeletal System. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 5 FreeCells need ENERGY to do all this work. Cellular respiration is the process where cells turn food into usable energy. When similar cells group together and work
together for the same purpose, they form tissues. For example, skin tissues protect our bodies from dirt and germs getting inside our bodies. Nerve tissue helps us feel things, such as if something is hot or cold. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 6 The Nitrogen Cycle Process: Nitrogen is taken in by plants through their roots, animals eat plants, and the nitrogen is passed along the food chain to animals. Herbivores get nitrogen by eating plants. Carnivores get nitrogen by eating herbivores. Nitrogen is returned to the soil when an organism dies – decomposers break down the dead organisms and change the nitrogen compounds in the dead organism’s body into the kind plants can use. Read more...iWorksheets: 4Study Guides: 1Vocabulary: 2 An ecosystem includes all the living and non-living things in an area. This includes populations and communities of many different animals. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 3 The flower is the seed factory of the plant – where the flower produces seeds. A flower’s sepals cover a developing flower bud in order to protect the bud while it grows. The petals of a flower are often bright and colorful. The stamen is the male part of a flower. The pistil of a flower includes the stigma, style, and ovary. The ovary of a flower contains seeds. The ovule is the part of the plant that becomes a fruit. Read more...iWorksheets: 5Study Guides: 1Vocabulary: 2 An important and essential interaction among living things involves the flow of energy within an environment. All living organisms need energy to survive! Energy moves through an environment through food chains and food webs. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 3 A plant can respond to the conditions of its environment. A plant can change its position and grow in a certain direction or manner to meet its survival needs and adapt to a varying environment. Read more...iWorksheets: 4Study Guides: 1Vocabulary: 2 There are many plants in the world. Some are plants that you know of and many you have never heard of before! The Fern’s Life Cycle. The Life Cycle of Moss. Monocots vs. Dicots….what are these? Read more...iWorksheets: 3Study Guides: 1Vocabulary: 2 Plants have two different root systems: a Taproot and a Fibrous Root system. Leaves of a plant are made of plant organs and tissues. The top layer of leaf, which protects the leaf, is called its epidermis. Leaves have tiny openings underneath them called the stomata which let air and water in and out of the leaf. Read more...iWorksheets: 5Study Guides: 1Vocabulary: 3 Scientists classify plants and animals according to the structures and characteristics of each organism. They compare and contrast organisms, and those with similar structures and characteristics are grouped together. Read more...iWorksheets: 5Study Guides: 1Vocabulary: 4 Standards
