only grow physically‚ it also grows by learning. The biology of learning is very interesting and taught me what learning really is like what is does‚ when it is done‚ and how it can be done better. The brain can learn to multi-task‚ to learn better by sleeping‚ and to understand information by what type of learner we are. This essay will tell you how the brain works and some other things you need to know about learning. In the essay “The Biology of Learning”‚ Stephen Londe tells us information to

Introduction In this investigation‚ me and my partners performed an experiment to find the different energy contents in food and different amounts of energy released when consumed. Throughout this experiment our procedure was to take different food samples and use a device known as a calorimeter made from a can of aluminum‚ one large paper clips and a string of copper wire to measure the amount of thermal energy released during a reaction. By measuring the temperature difference before and after
