This is  energy stored in the object. A tree  stores potential  energy in its wood. This enegy is released when we burn wood. The water in a lake also has potential energy. It becomes kinetic energy if the water flows into a rivers.]]> 2022-05-19 08:59:19 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2191013497 Thermal energy (Erika) https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2197237428 This energy comes from a heated substance. When thermal energy is transferred from or to an object, we call it heat. Warmer objects have more thermal energy than cooler object. Thermal energy also moves from warmer objects to cooler objects]]> 2022-05-24 07:17:49 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2197237428 Chemical energy (Erika) https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2197259934 This form of energy is released during a chemical reaction. For example, the chemical reactions inside batteries produce electricity. Our bodies also use chemical reactions to change food into energy.]]> 2022-05-24 07:32:36 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2197259934 Solar energy ( Alejandra ): The sun is the cleanest surce of energy. Solar planels do not pullute the enviroment. Solar energy is effective un places with very sunny climates. alor3 https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199136255  ]]> 2022-05-25 09:35:07 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199136255 Water energy (Celia) ceru3 https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199143866 Hydroelectric power is more than wind and sunligth and it does not cause any pollution . Building dams can destroy wildlife habitats and affect biodiversity on a areas.]]> 2022-05-25 09:42:54 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199143866 Geothermal energy (Erika) https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199145532 This energy is heat that comes from the centre of the Earth. Geothermal energy only exists in areas with volcanic activity. 

    It is a clean energy source because it does not cantribute to the greenhouse effect and it does not pollute the air.]]>     2022-05-25 09:44:38 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199145532     Wind energy(Alberto) https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199146576 We can build wind farms on land and in the sea. Wind turbines are only effective in windy places]]> 2022-05-25 09:45:42 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199146576 Coal (Erika) https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199154396 We burn coal to get energy and to produce electricity. Coal is a major source of fuel and the biggest source of air pollution ]]> 2022-05-25 09:53:15 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199154396 Crude oil(Alberto) https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199154689 We make crude oil into petrol for cars. Burning oil causes air pollution and contributes to climate change. ]]> 2022-05-25 09:53:28 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199154689 Biomass (Alejandra): This is all things and órganic matter. It includes Woody, crops,manure of animal origin and food waste. Se burn biomass in power station yo boil water and produce steam. This Steam turns a tubine and generales electricity. Biomass production can contribuite to desforestation and global warning. alor3 https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199158447 2022-05-25 09:56:44 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199158447 Natural gas (Celia) ceru3 https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199486446 This energy is more eficient thanthe other fossil fuels. Is barns more cleanly than coal or crude oil, but It still contributes to global waning.]]> 2022-05-25 14:36:07 UTC https://padlet.com/selvaillana/h6of1hnlxk6he1da/wish/2199486446
