Tropical rainforest A tropical rainforest is an ecosystem type that occurs roughly within the latitudes 28 degrees north or south of the equator (in the equatorial zone between the Tropic of Cancer and Tropic of Capricorn). This ecosystem experiences high average temperatures and a significant amount of rainfall. Rainforests can be found in Asia, Australia, Africa, South America, Central America, Mexico and on many of the Pacific, Caribbean, and Indian Ocean islands. Within the World Wildlife Fund's biome classification, tropical rainforests are a type of tropical wet forest (or tropical moist broadleaf forest) and may also be referred to as lowland equatorial evergreen rainforest.[3] Overview[edit] Tropical rainforests can be characterized in two words: hot and wet. Tropical rainforests are among the most threatened ecosystems globally due to large-scale fragmentation as a result of human activity. History[edit] Tropical rainforests have existed on Earth for hundreds of millions of years. Forest floor[edit]
Science: Earth Cycles We are finishing up a study of Earth Cycles this week. During this time we took a look at the Earth rotating and revolving. Here are two Make and Takes we created for these. We first made the model of the Earth using model magic clay and a straw for the axis. We showed how the Earth rotates or "turns like a top" towards and away from the sun creating day and night. Students saw how the tilt stays the same as they positioned and glued each Earth down representing the seasons. The corners flip up to create a square and each corner is labeled with the season's name. I have bundled these resources and more in one pack.

African Grey Parrot - Congo African Grey Congo African Grey Parrot The Congo African Grey Parrot (Psittacus erithacus erithacus), is the largest and more commonly known of the two types of the African Grey Parrot. Congo African Grey Parrots are approximately 12 – 14 inches (32-26 cm) in length and usually weigh 16 ounces (450 g). They are gray in color and have a solid black beak with a bright red tail. Congo African Grey Parrots originate in Central Africa, from the southeast portion of the Ivory Coast extending to western Kenya and down to Tanzania and Angola. The Congo African Grey Parrot from Congo can be somewhat larger and a lighter gray in color than one from Cameroon which would be medium-sized and a darker grey in color. It has been determined that if you start in the country of Ghana or Togo and radiate outward in all directions there is a progressive change in shade and size of the Congo African Grey Parrot. Congo African Grey Parrots are talented talkers and begin talking between 12 and 18 months old.
Tasks The Four Seasons | What Causes Seasons? The four seasons vary significantly in characteristics, and can prompt changes in the world around them.Credit: Shelli Jensen | Shutterstock The passing of a year can bring a marked change in the weather and the surrounding environment. The four seasons — winter, spring, summer, autumn — can vary significantly in characteristics, and can prompt changes in the world around them. The annual cycle Attributes of the seasons may vary by location, but there are still broad definitions that cross most of the boundaries. In the spring, seeds take root and vegetation begins to grow. In the summer, temperatures may increase to their hottest of the year. In the autumn, or fall, temperatures cool again. Winter often brings a chill. Location, location, location The timing and characteristics of the seasons depends upon the location on Earth. But for areas to the north and south, the seasons can change more significantly.

Congo African Grey Parrot CLASS: AVES ORDER: PSITTACIFORMES FAMILY: Psittacidae GENUS: Psittacus SPECIES: P. erithacus erithacus Common Name(s): African Grey, Congo Grey, Grey Parrot There are only three distinct birds in this genus; along with the Psittacus erithacus erithacus, there is Psittacus erithacus timneh and Psittacus erithacus princes. Whether or not they are different species, subspecies or simply variants of the main species, Psittacus erithacus, is still open for debate. Congo African Grey is the largest of the three types of Grey Parrot (the other two being the smaller maroon-tailed Timneh, and the darker colored Psittacus erithacus princes). Grey’s have a large white facial area, which flares back beyond the eye resulting in a masked appearance. Body length approximately 14-16 inches with a wingspan of approximately 18-20 inches. Congo African Greys are found in Equatorial Africa, ranging from Angola to The Ivory Coast, inland from Kenya to Tanzania. The African Grey is not considered endangered.
Lessons about the Sun and Earth’s Climate — The Sun and Earth's Climate — Beyond Weather & The Water Cycle X-Ray picture of our sun. Photo courtesy of blueforce4116, Flickr. The first principle of the The Essential Principles of Climate Sciences states: “The Sun is the primary source of energy for Earth’s climate system.” Concept A. In keeping with these concepts, we’ve highlighted lessons that help elementary students develop an understanding of how the Sun’s light warms Earth’s air, land, and water and how variation in daylight hours are associated with seasonal change. Solar Energy The Warmth of the Sun (Grades K-2) This introductory lesson helps students understand the sun’s role in heating and warming earth’s air, land, and water. Cooler in the Shadows (Grades K-2) In this lesson, students will make inferences about the cause of shadows by observing and making their own shadows in the sun. Sun. Our Super Star (Grades K-5) A multiday lesson plan about the sun. Investigating Radiation (Grades 3-5 with modifications) In this lesson, students investigate how different surfaces absorb heat.
UVB requirements of an African Grey | Bird Lighting Q. I have a hand reared African grey parrot and have just bought a bird lamp for the first time. I just wondered how many hours a day that I need to run the lamp and if I still need to use it in the summer when the parrot spends roughly 2 hours a day with me in the garden? A. This is a fantastic question and one that does deserve some explanation. It is safe to say that an average dose would be almost twice of that which is common to the UK summer. I would suggest that a captive grey is allowed to self-regulate its own level of exposure for 6-10 hours a day all year round. If we take the ParrotPro as an example of a system with defined parameters I would want to see a grey able to safely self-regulate under the lamps emission zone at a distance of around 12-15” from the lamp to the top of the birds head at the shortest point.

Parrot Facts: Habits, Habitat & Species Parrots are members of the order Psittaciformes, which includes more than 350 bird species, including parakeets, macaws, cockatiels and cockatoos, according to the Integrated Taxonomic Information System (ITIS). Though there are many types of parrots, all parrot species have a few traits in common. For example, to be classified as a parrot, the bird must have a curved beak, and its feet must be zygodactyl, which means there are four toes on each foot with two toes that point forward and two that point backward. Size Because the parrot order includes so many different species, parrot sizes vary widely. Habitat Most wild parrots live in the warm areas of the Southern Hemisphere, though they can be found in many other regions of the world, such as northern Mexico. Not all parrots like warm weather, though. With their colorful plumage and ability to mimic human speech, parrots are very popular pets. Habits Most parrots are social birds that live in groups called flocks. Diet Offspring
Seasons on Earth OpenClose Lesson Summary Overview Earth's seasons — the annual climate changes that different locations experience — result from a combination of Earth's orbit around the Sun and the tilt of Earth's axis. Earth's orbit brings it closer to the Sun in summer and farther away in winter. In this lesson, students use class discussion, interactive activities, hands-on activities, and videos to learn about the seasons, Earth's motion, and the role of its tilted axis. Objectives Know that Earth is tilted on its axis and that this tilt, by affecting the angle of incidence of sunlight, is responsible for the seasonsUnderstand how different angles of incidence affect surface heatingRecognize that different parts of the world experience different seasonal changesBe able to interpret satellite maps of the world that show seasonal differences in plant life Grade Levels: 6-8 , 9-12 Suggested Time Three class periods Multimedia Resources Materials Before the Lesson Arrange to start the lesson on a sunny day. 1.
