0ScienceMy daughter's science fair project was supposed to demonstrate the principle of buoyancy. She put a cork in a bowl of water, the cork floated, and she wrote, 'The water was not strong enough to hold the cork down.' Her teacher wrote back, 'The cork is less dense than water. It floats due to the buoyant force.'Show PunchlineShare
0ScienceMy son's homework said, 'If a train leaves Station A at 60 miles per hour and another train leaves Station B at 40 miles per hour, heading toward each other, when do they meet?' I did the math. He looked at me and said, 'Dad, trains do not leave stations at 60 miles per hour.' I said, 'This is a thought experiment.' He said, 'The train is in the picture. It has a cab. It has wheels. It is not a thought. I saw a train last week. It left the station at the speed of a man walking to the mailbox. The answer is not two hours. The answer is eventually, and probably not today.'Show PunchlineShare
0ScienceMy son's science project was supposed to demonstrate the water cycle. He put a bowl of water outside in the sun, waited two days, and wrote his conclusion.Show PunchlineShare
0ScienceMy kid's science project was supposed to demonstrate the concept of inertia. His teacher pushed his chair, he kept moving, and he wrote his conclusion.Show PunchlineShare
0ScienceMy son's science project was supposed to demonstrate the concept of density. He put a rock in a cup of water, the water level rose, and he wrote, 'The water got bigger.' His teacher wrote back, 'The water displaced. The volume increased due to the rock's density of approximately 2.7 grams per cubic centimeter.'Show PunchlineShare
82ScienceMy son's science project was supposed to demonstrate Newton's third law. He pushed against the wall, the wall pushed back, and he wrote his conclusion.Show PunchlineShare
21ScienceMy son's science project was supposed to demonstrate the concept of gravity. He dropped a rock off the balcony, timed it, and wrote in his report: 'Object fell. Conclusion: gravity works. Next time I will drop a heavier object to determine if speed increases.' His teacher wrote back: 'Please do not drop objects off the balcony. Also, Galileo covered this in 1590 and he did not have a balcony.'Show PunchlineShare
59ScienceMy kid's science project was supposed to demonstrate the concept of equilibrium. He stood on one leg, held a book over his head, and declared, 'I am balanced. I am the equilibrium.'Show PunchlineShare
69ScienceMy daughter's science project was supposed to demonstrate the water cycle. She made a bowl of water, put it in the sun, and said, 'Evaporation.' Then she put it in the freezer and said, 'Precipitation.'Show PunchlineShare
48ScienceMy kid's science project was supposed to demonstrate the concept of momentum. He ran into a wall, turned around, ran into the other wall, and said, 'I'm maintaining my velocity.'Show PunchlineShare
24ScienceMy kid's science project was supposed to demonstrate the concept of energy transfer. He slammed his hand on the table and said 'kinetic energy,' picked up the table and said 'potential energy,' put the table down and said 'thermal energy,' and then sat in the chair and said, 'I am now the control group.' His teacher gave him an A.Show PunchlineShare
14ScienceMy kid's science project was supposed to demonstrate the concept of pressure. He stood on one foot, held his breath, squeezed his eyes shut, and declared, 'I'm putting more pressure on this foot than the other one.' His teacher asked, 'And what did you observe?'Show PunchlineShare
56ScienceI was explaining gravity to my kid at the dinner table. He pushed his peas off the plate and said, 'See? Gravity works on peas.' I said, 'Exactly.' He said, 'But it doesn't work on my patience. I've been sitting here for forty minutes and I'm not moving.'Show PunchlineShare
