  6. 6. Exampel of appliances that make use of energy transform To save cost c) Kicking Ball a) Moving Car b) Lighting Candle Food Water Sun Fuel Batteries Reduce pollution Avoid wastage Heat Light Electrical Kinetic Chemical By living things to carry out life processes-moving to move,boil,melt Some energy resources cannot be replenished when used up WHY USE ENERGY WISELY FORM OF ENERGY WHY ENERGY IS NEEDED? CAN BE TRANSFORMED SOURCES OF ENERGY ENERGY Wind Sound
  7. 7. 1.2 Food Preservation ( Process whereby food turning Bad is slowed down Example Eggs, water Reason ……………… .. ……………… .. Example Egg, vegetables, fruits Reason Cold temperature slow down the growth of bacteria and fungi Example ………………… .. Reason Bacteria and fungi cannot grow without water Example …………………… Reason Bacteria and fungi cannot grow without water Reason Destroy microorganism Example Meat, yogurt Reason Bacteria and fungi cannot grow without air Example ……………………… Reason Bacteria and fungi cannot grow in very Salt substances Example ………………… . Reason ………………… . ………………… . ………………… . Example Fish, meat …………… . Bottling/ canning Salting Freezing Reason Prevents the growth of bacteria and fungi Example Fruits, chili, fish ……………… .
