In this egg drop project, a container was built to house one egg and was then dropped at various heights. The purpose of this lab was to find how impact time affected the force with which an object, the egg container, hits another surface as the momentum moves to zero. Our hypothesis states that if the impact time is stretched longer then the force exerted on the egg would decrease, making the egg less likely to break. The independent variables for the egg drop project was the height at each drop; the dependent variables were impact time and survival of the egg. The controls were mass, design of the container, and the egg.
The Story of the Horned Toad Chapter #1 It was 1935, Boston Massachusetts and there lived an 8 year old boy named Phrynosoma. His mother died an hour ago, and before she died she called a taxi to take him to the airport to live with his cousins in Guatemala,. When they were boarding the plane he saw that they didn't put enough fuel in the plane. Mabe they put the fuel in ahead of time, he thought.
First of all, an alka-seltzer is an a little tablet that helps with multiple pain. For example, alka-seltzer helps with migraines, headaches, sinus headaches, muscle pain, and symptoms of pain. Alka-seltzer contains aspirin, sodium, hydrogen carbonate, citric acid, natural flavors, and artificial flavors. These are just some of the ingredients. When an alka-seltzer dissolves it releases all of the medicine.
The effects of where these larvae are laid can dictate the fate of these gall fly larvae. A study shows that avian predators can assess a gall 's content prior to pecking it open, preferring galls that are inhabited by gall fly larvae. Bird predation was found to be concentrated near the places with a lot of tree cover where S. gigantean a large centipede tends to pray few attacks occurred in the open where golden rods are prevalent. The study was a field experiment to observe the preference of avian predators on galls in different habitat types and that had different sizes, and heights of galls. It is possible that birds have either learned through experience or evolved through natural selection to choose the more profitable galls (Poff et al. 2002).
There was no known Earth before Gael, the God of Earth. He would roam around the heavens, looking for dirt holes. Whenever he would find a dirt hole, he would throw rocks into it. He would throw enough rocks to fill the hole entirely. He loved when the dirt holes were filled.
Parachutes were invented about a century ago, but they continue to evolve, as inventors devise ever-better ways to improve their safety and handling. As indicated by the United States Parachuting Association, there are an expected 3 million jumps for every year, and the fatality count is 21 (for 2010). That is a 0.0007% possibility of dying from a skydive, contrasted with a 0.0167% shot of kicking the bucket in a fender bender (considering driving 10,000 miles). In layman 's terms, you are around 24 times more prone to pass on in a pile up than in a skydiving one. Rationale and aim: Extreme sports represent the most ferocious activities that challenge our natural human instincts.
Lone Pairs ADI Lone pairs, the electrons that the central atom does not share during a covalent bond, can and will affect the shape of a molecule in various ways. During this lab, the goal was to answer the guiding question of, “How does the number of lone pairs affect the shape of the molecule?” Answering this question served to cement in those participating in the lab an understanding of the affect a central atom’s number of lone pairs will have on the shape of the molecule, and be able to identify a pattern of molecular shapes and their central atom’s lone pairs. We conducted this lab by first experimenting with 3-D molecular structures on a website, becoming familiar with the geometry of molecules and what exactly lone pairs were.
The egg-speriment was one of the ways to observe how the cell membrane works with different liquids entering and leaving. The egg is a model of the cell membrane that is soaked in vinegar for Days 1 and 2, water for Days 3 and 4, food coloring with water for Day 5, salt water for Day 6, and finally Arizona Tea for Day 7. My hypothesis was when the egg is soaked in vinegar, it will make the shell rougher, water will make it soft, food coloring will make it colorful, and salt water will make it a rocky shell. In this egg-speriment, the manipulated variables is the liquids, the responding variable is circumference, and the controlled variable is the egg.
Daedalus was one of the cleverest men in all of Crete. He had created a maze that was called a Labyrinth. Inside the Labyrinth lived a Minotaur, a half –man half-bull creature. King Minos used the Labyrinth and the Minotaur to sacrifice people to the gods.
Reaction Time Lab Report Research Question: How does the physiological stimulus of music affect the reaction time of a subject? Aim: The aim of this experiment is to see how reaction time can be tested in a variety of ways and can be affected by a number of environmental and physiological factors. Hypothesis: I have reached the hypothesis that the reaction time will increase whilst the subject is listening to music.
I don't accept my current grade, because it is wrong, and my grade should be higher than D in anyhow according to Dr.Scandale's grading policy. The following explanation is made on my behalf. Lab 1.1 grade = 0 "what should be the correct grade?", and if different, explain why
I read The Boy Who Harnessed the Wind for the Sakai Reads event. The Boy Who Harnessed the Wind takes place in Malawi, Africa in a time of hardship and poverty. Young William Kamkwamba is the son of a poor African farmer. During a Man vs Nature conflict he drops out of school but as a result finds his confidence in himself and learns that he has an incredible scientific mind. He is a very curious and ambitious person and is not afraid to try new things.
