So we will have a very powerful battery that the people just have to flip a switch to turn on which will create a chemicle reaction that will send an electric pulse down a wire which will be electrical energy which will power a nail and when the nail has the energy it will mangnitize and have mecahnical and thermal energy then the magnatized nail will pull up the paper clips which will create and imbalence between the weight of the paperclips and tennis ball which will roll down and and hit a swicth which will turn on a light and then the light will turn on and then power a songboard which will play a song and then the sticker will come out in the slot and then the kid can pick up the sticker. energies: Chemical ideas: battery powering magnet. chemical reaction baking soda vinager mentos and diet coke mechanical ideas: rolling ball falling things and hitting objects acoutstic: thump from falling objects hitting toy piano crashing mp3 player playing music thermal: piano playing battery nail heating up electrical: piano playing battery giving of power sticker diespensing electromagnetic: the lights lighting up on the piano glow sticks light bulb on battery The energy flow in a closed system goes from the power source though the conducter to the lightbulb. The power sorce would be the battery which is chemical energy. Then the chemical energy gets converted to electrical energy which gets converted to thermal and electromagnetic whih powers the light and makes it light up. THen the energy is tansfered to mechanical energy and is transferred to the envirnment. Energy exstavaganza: Deandre and I's experiment was what surface would the popper go the highest when dropped from one meter. Deandre and I learned that the harder the material the higher the popper would go when dropped from one meter. This is because the harder the material the less energy it absorbs when it hits. For example when we tried our experiment on leather it didn't work well because the leather is soft and absorbs the impact. Then when we tried it on the very hard table top it hit the ceiling because their was not much of the energy transfered. That is why the popper would go higher when dropped on a harder surface that it would go higher. Friction played into it when the popper hit the ground and rubbed against the ground then went back up but transfered some of the energy to thermal energy.
