Eclipse Simple video animation   (watch the short video to answer the following Guide Questions): Guide Questions: 1. What are the 2 kinds of eclipses? 2. Describe the difference between umbra and penumbra. According to the National Aeronautics and Space Administration , or NASA , " An eclipse happens when a planet or a moon gets in the way of the Sun’s light." Two kinds of eclipses on Earth: 1. solar eclipses 2. lunar eclipses Two distinct parts of the Earth’s shadow during a solar eclipse : 1. Umbra – refers to the darkest part of the moon’s shadow formed on the Earth where a total solar eclipse is seen 2. Penumbra – refers to the lighter part of the moon’s shadow formed on the Earth where a partial solar eclipse is visible Two distinct parts of the shadow created during a lunar eclipse : 1. Umbra – the darker inner region of the Earth’s shadow where all the sunlight is blocked out 2. Penumbra – the lighter outer region of the Earth’s shadow where the sunlight is partia...

What are the benefits of games in education? "One such way to better use technology is to engage pupils in online gaming that enhances and positively reinforces their learning. This is one of the key benefits of games in education. Computers, mobile phones and tablets have allowed students new and innovative ways of learning."  Reference:  Benefits of Online Games for Students | Games in Education (reviewgamezone.com) Check out our list of games that will help our students enjoy the lessons in Science!

Greenhouse Effect Simple video animation Water vapor  - the concentration of this gas is largely controlled by the temperature of the atmosphere. Carbon dioxide - a good absorber of energy (infrared radiation) and the most common gas produced by human activities. Methane - 30 times stronger than carbon dioxide as an absorber of infrared radiation. However, it is present in smaller concentrations. Nitrous oxide - a relatively long-lived gas that has increased in atmospheric concentration due mainly to agriculture. Ozone - a highly reactive gas, both a natural and a man-made product. Halocarbons - composed of carbon, chlorine, fluorine, hydrogen, and chlorofluorocarbons or CFCs. CFC gases can absorb more infrared radiation than any other greenhouse gas. 1. The Sun’s heat enters the atmosphere as SOLAR RADIATION. 2. About half of the heat is reflected or absorbed by clouds and the atmosphere. 3. The rest reaches the Earth, where it absorbs by oceans and land. 4. The Earth also release...

 Earth’s Movement and Seasons Simple video animation   (watch the short video to answer the following Guide Questions): Guide Questions: 1.  At how many degrees is the Earth's axis tilted? 2. What is the effect of the slanting position of the Earth, along with its constant movement around the Sun? Our home planet Earth is the third planet from the Sun and the only planet known to have life. Did you know that Earth is not perfectly round? It is an oblate spheroid. It is constantly spinning like a top around its axis. This spinning is what we call rotation . Rotation - the movement of the Earth on its axis over a twenty-four (24) hour period It rotates eastward. As viewed from the north pole star Polaris, Earth turns counterclockwise. The effect of Earth's rotation is that we have a cycle of daylight and darkness approximately every 24 hours. This is called a day . While the Earth spins on its axis, it also revolves around the Sun. It takes 1 year or 365.25 days to complete...

 Layers of The Earth’s Atmosphere Simple video animation   (watch the short video to answer the following Guide Questions): Guide Questions: 1. What layer of the Earth’s atmosphere does most weather occur? 2. Where can we find the Protective Ozone? The atmosphere is a blanket of air that protects the Earth from ultraviolet radiation and meteors. It primarily consists of 78% nitrogen and 21% oxygen gases. The remaining 1% contains several inactive gases - argon, neon, helium, hydrogen, and xenon - and other several gases that vary in concentration - water vapor, carbon dioxide, methane,  nitrous oxide, ozone, and chlorofluorocarbons. Earth's atmosphere has a series of layers. Moving upward from the ground level, we have the: Troposphere Stratosphere Mesosphere Thermosphere Exosphere 1. Troposphere Temperature: DECREASES (from 17°C to -51°C) Characteristics: It is the  lowest region  of the Earth's atmosphere. It is  where we live  and most  w...
