Bouncy Ball Experiment Aim: The aim of this experiment is to investigate the efficiency of a bouncing ball‚ and the factors which affect its efficiency. Prediction I predict that the higher I drop the ball from the higher it will rebound up‚ because it will have more gravitational potential energy the higher dropped from. As it is dropped the ball will have kinetic energy‚ and then when it hits the ground changes to heat and sound energy‚ and kinetic as it rebounds back up. The higher up

hard surface. This toy is known as the bouncy ball. Usually bouncy balls are made of natural rubber‚ ways have been discovered in which bouncy balls can be made from leather‚ plastics‚ and other types of polymers. In this experiment we created not just any regular bouncy ball‚ but one whose materials are not harmful to the environment. In other words‚ we created the perfect eco-friendly bouncy ball. The materials we used to create this eco-friendly ball were polyvinyl alcohol (PVA) and polyvinyl

In our past experiments and observations we have found that air is in fact matter we know this because air takes up volume and mass. In the beach ball demo‚ we tested the beach ball without air and the mass was 56.1 grams and then we tested it again with air and the mass equalled up to 56.3 grams. This shows us that air takes up space. In the investigation 1.2‚ we tested 3 demonstrations. And in the second demonstration In demonstration 2 the cup was put into the water‚ upside down‚ the beaker

When you have all that done just put vinegar in the bowl with the hard boiled egg ( How to make a bouncy egg). After letting the hard boiled egg set in the vinegar for three days take it out and let it set on a paper towel for a couple of minutes. After letting it set on the paper towel take the egg and set it under cold

Much like Gilgamesh’s quest for fame‚ of wanting his “name stamped on bricks” (70)‚ Odysseus also demonstrates a lust for power and fame. Odysseus relates to Gilgamesh in the sense they are both self-centered‚ proclaimed heroes. Gilgamesh seeks Humbaba to slay him simply for the fame of it while Odysseus reveals his identity to Polyshemus simply to boast of his accomplishment. This completely backfires on him when the Cyclops throws a slab of mountain at their boat‚ resulting in the near death of
