Activity Magnetic Fishing Objectives: At the end of this activity, the student should be able to: 1. define what is a magnet 2. identify what kind of materials are being magnetize 3. site some uses of magnet 4. perform the activity with discipline, collaboration and cooperation Background: A magnet is any object that has a magnetic field. It attracts ferrous objects like pieces of iron, steel, nickel and cobalt. In the early days, the Greeks observed that the naturally

Reaction Paper on the Core The Core is a film that is about the sudden stop of the Earth’s core that causes many sudden happenings like the birds suddenly start flying in all directions like they were blind and were going mad but because of that the geophysicists agree to drill down to the core and restart the rotation before all humans in the world would die. The scenarios are likely the scenarios in end of the world movies but in this movie the thing that make it the end of the world is

attain the same lift - this implies both a longer takeoff roll and a higher true airspeed which must be maintained when airborne to avoid stalling. Density Altitude Computation Chart[1] Density altitude is the altitude relative to the standard atmosphere conditions (ISA) at which the air density would be equal to the indicated air density at the place of obser• The aircraft will climb slower as the result of revation. In other words, density altitude is air density given duced power production

Electromagnetic fields are present everywhere around the atmosphere but are not visible. Electric fields are produced by the local build-up of electric charges in the atmosphere associated with thunderstorms. The earth's magnetic field causes a compass needle to orient in a North-South direction and is used by birds and fish for navigation.[ http://www.who.int/peh-emf/about/WhatisEMF/en/]. Now we will talk briefly about the atmospheric electromagnetic fields. There is always free electricity in

dioxide deposits continue to flood the atmosphere it is now considered one of mankind’s largest challenges in the 21st century. Global warming is climate change that causes the average temperature of the Earth's lower atmosphere to increase. Global warming can have many different causes, but it is most commonly associated with human interference, specifically the release of excessive amounts of greenhouse gases. With this gas buildup, the Earth's atmosphere warms to unnatural temperatures, which

Oxygen - A nonmetallic element constituting 21 percent of the atmosphere by volume that occurs as a diatomic gas, O2, and in many compounds such as water and iron ore. It combines with most elements, is essential for plant and animal respiration, and is required for nearly all combustion. Atomic number 8; atomic weight 15.9994; melting point -218.4°C; boiling point -183.0°C; gas density at 0°C 1.429 grams per liter; valence 2.

remaining. This is why the bottle was still warm because the particles still had kinetic energy. How does the composition of the gases in the bottles differ from the composition of gases naturally found in the atmosphere? The gases in the bottles differed from the gases found in the atmosphere in 2 ways:-The gases in the bottle were not produced naturally because of the use of Alker seltzer tablets and they gases in the bottles were trapped and filled into the bottles they were not found naturally

warming, discuss the extent to which you agree with this statement. (40 Marks) Global warming refers to the way that heat is being trapped in the atmosphere due to the greenhouse effect. The greenhouse effect is when heat is trapped in our atmosphere by gases such as Carbon Dioxide. The greenhouse effect is actually a good thing because without it, the Earth’s global temperature would be around 33 degrees’ cooler which would mean life on earth would be completely different as ecosystems etc. would have
