Oogenesis: How the Female Reproductive System Produces Eggs - Video & Lesson Transcript. The Ovum Oogenesis is the process by which the female gametes, or ova, are created.
The female gamete is called an ovum. Sometimes people will refer to female gametes as eggs, but the term egg can include more than one stage of development, and the definition of an egg also changes depending on the type of organism. For example, the entire prenatal development of birds occurs inside an egg, but in placental mammals, after the egg is fertilized and starts dividing, nobody calls it an egg anymore. So, we're going to use the more precise term for a mature female gamete which is ovum (or ova for the plural form). Meiosis You may also remember that in order to create haploid gametes, a cell must go through the process of meiosis which involves replicating its genome and then dividing, not once, but twice.

GETTING ENERGIZED! Teacher’s Activity Guide for Elementary Grades 3-6pdf. Magchar pres. Electricity & Magnetism: Magnets. A magnet is an object or a device that gives off an external magnetic field.
Basically, it applies a force over a distance on other magnets, electrical currents, beams of charge, circuits, or magnetic materials. Magnetism can even be caused by electrical currents. While you might think of metal magnets such as the ones you use in class, there are many different types of magnetic materials. Iron (Fe) is an easy material to use. Other elements such as neodymium (Nd) and samarium (Sm) are also used in magnets. Electricity_lesson_plan.pdf. Electricity_definitions.pdf. ELECTRICITY - GRADE 6 SCIENCE. CLP Group - PowerU. Heat - Science for Kids! Lessons and Activities about Heat and Insulation — Keeping Warm. These lessons help students develop a basic understanding of heat and how heat is produced.
Teachers may wish to further develop a study of heat by exploring how different surfaces and colors reflect and absorb light. For lessons and activities about albedo, please see “Hands-on Science and Literacy Activities about Solar Energy” in the October 2008 issue of Beyond Penguins and Polar Bears. The Warmth of the Sun (Grades K-2) To help students broaden their understanding of the sun, particularly its critical role in warming the land, air, and water around us. When Things Start Heating Up. © 2012 Clipart.com Purpose To understand how and why heat is produced from things that give off light, from machines, or when one thing is rubbed against another.
Context. StudyJams. Investigating Light and Color, lesson plan for grades 3,4,5. Grades: 3, 4, 5 Related Subjects: Science, Visual & Performing Arts Medium: Sculpture Class time required: 1 X 50 minute session Author: Museum of Photographic Arts Summary Students investigate the properties of light.
They begin with an exploration of the visible light spectrum and follow up with an investigation into the primary colors of light. Elementary Physical Science - Light Energy. By completing computer and hands-on activities, students experiment with the concepts of transparent and opaque objects, shadow and reflection.
As they record what they’ve learned, students build math and science skills by measuring length and making a graph to log results. Take the online material further by making use of the professional development available in the form of printable teacher guides. These teacher guides include hands-on activities, follow-up discussion questions and more to help students recall information and enhance the online activities. Additional professional development is available in the form of Teacher Lessons. These help you prepare for each lesson by allowing you to go over the student material prior to implementation.

During a typical trip to school, your car will undergo a series of changes in its speed.
If you were to inspect the speedometer readings at regular intervals, you would notice that it changes often. The speedometer of a car reveals information about the instantaneous speed of your car. It shows your speed at a particular instant in time. The instantaneous speed of an object is not to be confused with the average speed. Average speed is a measure of the distance traveled in a given period of time; it is sometimes referred to as the distance per time ratio. On the average, your car was moving with a speed of 25 miles per hour. Motion: Introduction. Motion is one of the key topics in physics.
Everything in the universe moves. It might only be a small amount of movement and very very slow, but movement does happen. Don't forget that even if you appear to be standing still, the Earth is moving around the Sun, and the Sun is moving around our galaxy. The movement never stops. Motion and Forces. Forces and Motion activity 1: Predicting speed and directions changes (Inquiry Based) - PhET Contribution. Force and motion 5 6 unit guide. Matter: Chemical vs. Physical Changes. It is important to understand the difference between chemical and physical changes.
Some changes are obvious, but there are some basic ideas you should know. Physical changes are usually about states and physical states of states. Chemical changes happen on a molecular level when you have two or more molecules that interact. 5th grade science physical changes in matter.
