Science

• A biome is a group of land ecosystems with similar climates and organisms.
• There are 6 major land biomes and 2 major water ecosystems.
• The area’s biome is determined mostly by its climate (temperature and precipitation).
• The deep zone of the open ocean is below the surface zone, and is totally dark and home to many bizarre organisms.
• The surface zone of the open ocean is the first few hundred meters deep, where light penetrates.
• Coral reefs may form in water that is warm.
• There are two main types of rain forests: Temperate Rain Forests and Tropical Rain Forests.
• Temperate Rain Forests, also known as “temperate”, are found on the Northwestern coast of the U.S. and receive more than 300 cm of rain per year.
• Tropical Rain Forests are found in regions close to the equator and are warm and humid all year long, receiving a lot of precipitation.
• Deserts are areas that receive less than 25 cm of rain per year and some deserts receive no precipitation at all during one year.
• Deserts often undergo large shifts in temperature during the course of a day.
• Organisms that live in the desert must be adapted to the lack of rain and extreme temperatures.
• Saguaro Cactus stores water in its stem.
• Gila monster spends weeks in its cool, underground burrows.
• Many other organisms are only active at night when it is cooler.
• Grassland, also known as prairie, is an area that is populated mostly by grasses and other non-woody plants and receives 25 to 75 cm of rain per year.
• Fires and droughts are common in grasslands.
• Savanna is a grassland that is located closer to the equator than prairies and can receive as much as 120 cm of rain per year.
• In addition to grass, scattered shrubs and small trees can grow in the savanna.
• Grasslands are home to many of the largest animals on Earth.
• Tundra is an extremely cold and dry biome that usually receives no more precipitation than a desert biome, with most soil being frozen all year long (permafrost) and during summer, the top layer of soil thaws, but the rest remains frozen.
• Grazing by large herbivores helps to maintain these grasslands.
• Rivers and streams are bodies of moving water where animals adapt to the current by hooking and sucking to cling to rocks or have streamline bodies, with few plants or algae able to grow due to the strong currents.
• Estuary is where freshwater of a river meets saltwater of the ocean.
• Marine ecosystems include estuaries, intertidal zones, neritic zones, and the open ocean.
• Many living things live in the neritic zone.
• Boreal forest, also known as taiga, is mostly made of coniferous trees, such as Fir, Spruce, and Hemlock, and has very cold winters and warm and rainy summers.
• Deciduous forests receive enough rain to support the growth of trees and other plants, with a growing season of 5 to 6 months.
• Neritic Zone is the area below the low tide line which extends over the continental shelf, where sunlight passes through, allowing photosynthesis to occur and plants to grow.
• Intertidal Zone is the area between the highest high tide line and the lowest low tide line, where organisms must be able to survive the pounding waves, water level changes, and temperature changes.
• Deciduous trees are trees that shed their leaves and grow new ones each year, such as Oaks and Maples.
• Freshwater ecosystems include streams, rivers, ponds, and lakes.
• Ponds and lakes are bodies of standing or still freshwater, with lakes being larger and deeper than ponds, and ponds being shallow enough for sunlight to hit bottom, allowing plants to grow there.
• Rock-forming minerals can be identified based on properties.
• The importance of rocks in daily lives can be valued.
• Upload it through google classroom, soft copy only.
• Choose one of the minerals then you make an infographic about it in terms of characteristics, properties and its significance it can be health, economic or scientific.
• Rocks can be classified into igneous, sedimentary, and metamorphic rocks.
• Minerals are the building blocks of rocks.
• Mineralogists use criteria to determine whether a material is classified as a mineral or not.
