6th Grade Science Worksheets and Study Guides
The big ideas in Sixth Grade Science include exploring the life, earth, and physical sciences within the framework of the following topics: “Structures, Processes, and Responses of Plants” (structure and function of plants); “Structures, Processes, and Responses of Animals” (structure and function of animals); “Earth’s Atmosphere and Weather” (atmospheric properties and processes); and “Conservation of Energy” (properties of energy, work, and machines).
A bird is an endothermic vertebrate that lays eggs, has feathers, and has a four- chambered heart. A mammal is an endothermic vertebrate that has skin covered with fur or hair, a four-chambered heart, a wide arrangement of teeth, and young that are born alive and feed by milk that was produced by the mother’s body.

The structures within the cell are known as organelles, which are all of the structures within the cell that carry out specific functions. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 4There are many characteristics that scientists use to determine if something is alive. The characteristics are very specific and are applicable to all of the different species that exist on our planet. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 4FreeThe Earth is unique in our solar system because it has an atmosphere that can support life. By comparison, Venus has an atmosphere that is high in ammonia and other caustic gases; it is so dense that it would crush a human. On the other hand, Mars has no atmosphere at all.

Nonrenewable resources are resources that, once consumed, cannot be replaced. Because oil, natural gas, and coal are the products of plants and organisms, they are known as fossil fuels. Fossil fuels are ultimately a limited resource, it is important to develop and use renewable energy resources.

Small streams that feed water into larger rivers are called tributaries. Rivers are closely interconnected and flow from higher to lower elevations where the water collects in larger and larger rivers until it ultimately flows into the oceans.

External fertilization is when the female’s eggs are meeting with the male’s sperm outside of the female’s body. Three major groups are the jawless fish, cartilaginous fish, and bony fish. An amphibian is a vertebrate that is ectothermic. Most amphibians live the beginning of their lives in the water. A reptile is a vertebrate that is ectothermic and has scaly skin and a pair of lungs. Lizards, snakes, turtles, tortoises, and crocodiles are all examples of reptiles.

Read more...iWorksheets: 3Study Guides: 1Vocabulary: 8Groundwater is fresh water stored in regolith and bedrock. Even though solid rock like granite or marble has no pores, it often has a series of cracks and possibly faults. Water accumulates in the cracks in solid bedrock and, at times, is a source of water. A layer of rock material that can store water and allow the movement of water through the ground is called an aquifer.

Planet Earth is home to 8.7 million species, scientists estimate. Animals have adapted to feed on different types of food. There are animals that eat only animals (carnivores), animals that eat only plants (herbivores), and animals that eat both plants and animals (omnivores). Read more...iWorksheets: 3Study Guides: 1Vocabulary: 4The field of Geology includes a number of specialized disciplines including: Mineralogy - the study of minerals, Paleontology - the study of fossils, Petrology - the study of rocks, Geophysics - the study of the physics of the Earth and its atmosphere, Meteorology - the study of weather and weather prediction, Seismology - the study of earthquakes, and Volcanology - the study of volcanoes. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 1Matter is anything that takes up space and has mass. Some of its properties are physical and would include such things as color, volume and weight. Other properties are chemical and deal with how matter chemically reacts with other materials. Matter can undergo both physical and chemical changes. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 2Worksheets: 4Study Guides: 1Vocabulary: 1Geologists use a variety of different types of maps to model or depict the three-dimensional Earth on a two-dimensional surface. Each type of map serves a purpose because each type has its special strengths: Topographic Maps, Mercator Projections, Conic Projections, Azimuthal Projections.

Snails, octopuses, clams, and oysters are all species of mollusks. Arthropods are invertebrates with external skeletons, segmented bodies, and appendages. Appendages are structures that are jointed and attached to the body.

The waste substance itself is the pollutant. A natural resource that can be replenished is called a renewable resource. In most cases, water is a renewable resource. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 1Photosynthesis is a process powered by sunlight that uses carbon dioxide and water to produce oxygen and food. The process requires six molecules of water and six molecules of carbon dioxide. These molecules undergo chemical changes and oxygen and sugars like glucose are produced. The oxygen is let go through the stomata and the sugars are used to power cell functions. Read more...iWorksheets: 4Study Guides: 1Vocabulary: 2An angiosperm is a plant that produces seeds within a fruit. Reproduction begins when the pollen from the anther is in contact with the stigma. Eventually the egg will be fertilized in the ovule that is in the ovary and turn from a zygote to an embryo inside the seed. The life cycle of angiosperms among the different species is very similar: Pollination, fertilization, and the development of fruit.

Igneous rocks form when liquid rock cools and hardens. Sedimentary rocks: Clastic, Chemical, Biochemical or organic. Metamorphic rocks: foliated and non-foliated (or massive). Read more...iWorksheets: 4Study Guides: 1Vocabulary: 3Worksheets: 3Vocabulary: 3Matter exists in three different states or phases: solid, liquids and gases or vapors. A solid has a definite shape and volume, A liquid has a definite volume but no definite shape and A gas has neither a definite volume nor shape. Gases or vapors are influenced by three factors: temperature, volume and pressure. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 1Until recently, people thought that sponges were plants. The fact that they take in food puts them into the animal kingdom. When they are adults, they do not move. They attach themselves to a hard surface where they live out their lives. The structure of a sponge is very basic with some specialized tissue, but lacking organs and organ systems.

He used photographs to prove that there are galaxies beyond our own. Prior to this, scientists believed that our galaxy was the entire universe. In 1990, the Hubble Space Telescope (clearly named in honor of the great 20th century astronomer) was launched by NASA and has provided some of the most spectacular images of the universe ever seen.

The boundary or line delineating different air masses is the
weather front. A small weather system that has intense energy that creates heavy
rains, high winds, and lightning is called a thunderstorm. A hurricane is an extremely large, tropical, rotating weather system that has sustained winds of at least 119 km/hr. Read more...iWorksheets: 3Study Guides: 1Vocabulary: 4. Read more...iWorksheets: 3Vocabulary: 2
