0ScienceMy daughter's science fair project was supposed to demonstrate density. She put a rock, a coin, and a paperclip in a glass of water. The rock sank. The coin sank. The paperclip floated. She wrote her observation: 'The paperclip is less committed to the bottom than the other objects.'Show PunchlineShare
0ScienceMy son's science fair project was supposed to demonstrate air pressure. He built a small device with a balloon and a straw. He presented it to the class. He blew into the straw. The balloon inflated slightly.Show PunchlineShare
0ScienceMy son's science project was supposed to demonstrate the scientific method. He asked a question, made a guess, did the experiment, and wrote down what happened.Show PunchlineShare
0ScienceMy son's science project was supposed to demonstrate a controlled experiment. He set up two cups of water. He added a drop of food coloring to both. He wrote his observation.Show PunchlineShare
0ScienceMy son's science project was supposed to demonstrate the water cycle. He put a bowl of water on the windowsill, waited two days, and wrote his observation.Show PunchlineShare
0ScienceMy son's homework asked, 'What is the difference between a hypothesis and a theory?' He wrote, 'A hypothesis is when you guess. A theory is when you guess and then you write a whole essay about it so no one can tell you you're wrong.' His teacher wrote, 'Close, but a theory is a well-substantiated explanation.'Show PunchlineShare
0ScienceMy kid asked, "Dad, why do we call it 'gravity' if it doesn't feel like a force? It just feels like everything is heavy."Show PunchlineShare
0ScienceMy son's science project was supposed to demonstrate the concept of gravity. He dropped a rock, it hit the ground, and he wrote his conclusion.Show PunchlineShare
0ScienceMy son's science project was supposed to demonstrate photosynthesis. He put a leaf in a jar of water, waited a week, and wrote, 'The leaf got wet. The water got leafy. We are both changed.' His teacher wrote back, 'Photosynthesis is the process by which plants convert light energy into chemical energy.' My son wrote back a response.Show PunchlineShare
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
