Jet Propulsion Laboratory

Safety standards within a laboratory should be designed in a way that eliminates risks due to using potentially dangerous practices or procedures and dangerous materials. All laboratories are potentially dangerous places, and it is the actions and attitudes of those working there that determine their safety and that of their colleagues and ultimately of the whole community. The manual identifies the biological agents that are in use within the laboratory. It also points out the exposure…

Personal Write up For this lab, bottle rockets were to be made by the materials of duct tape, a tennis ball, cardboard, and a liter bottle. Using water as fuel, the rocket that is constructed was launched at the pressure of eighty PSI. The objective of this lab was to build the rocket efficient enough to launch at a range of two hundred to three hundred feet by calculating different variables. The independent variables of this lab were the shape and mass of the rocket, the angle degree the…

Paul Fitts and Michael Posner created a 3 stage model and suggested any learning of a new motor skill involves this model (Magill 2014). During the first stage, known as the Cognitive Stage, the novice learner will try to familiarize with the movement. The learner will analyze the objective of the movement, what they are trying to accomplish, and how to do it. This first stage of the model will be accompanied with numerous of errors and lack of consistency. Also seen in this stage, the learner…

The effects of deployment: Since October 2001, approximately 1.6 million United States troops were deployed to Afghanistan and Iraq striving for freedom. The most current statistics on the makeup of deployed military is 90% men, 10% women, 53% married, 68% married couples with children, 32% without children, 47% single, 13% single with children, and 87% single without children(Garcia). Soldiers enduring an extended deployment of six months or greater endure a five-stage emotional cycle…

The possibilities of space exploration are unknown, but with the advancements that are to come interstellar travel is one of those possibilities. The propulsion systems these spacecraft are to be far more advanced that of what is in current use. As stated earlier if nuclear fusion is to be incorporated into propulsion systems the distance in which mankind is to travel throughout the universe would increase greatly. Instead of being able to reach Mars in two to three months, it could…

The change process based on Prochaska’s theory, is a model that social workers use to help their clients during changes in their life that they may be going through. A client may be battling an addiction that they are trying to stop, or they may be having self-defeating thoughts about themselves that they cannot control. It is usually a process in which someone is trying to change some part of their lifestyle. Not everyone is successful in changing their unhealthy behaviors, and this model helps…

act as a surface lander, would be attached and be able to undock from the command module. The command module would be equipped with a SEP system to get the crew to and from the Martian system. The lander/ habitation module would have a LOX-methane propulsion system capable of returning it to Martian orbit to rendezvous with the command module. Testing of the spacecraft design includes several phases. The first testing phase is the terrestrial phase. Each component of the spacecraft will undergo…

THE DEADLY TWITCH A Fantastic Way To Fish the Baby ShallowRaider I've made this statement before, and it's definitely worth repeating -- "No lure triggers more strikes from shallow cover muskies, conditioned from repeated casts, than the twitched minnow bait". I've also made the claim "no other lure is a more efficient tournament musky bait than the twitched minnow bait". Statistics prove my claim to right on. The minnow bait has proven to be the best trigger bait, on pressured muskies, by…

The Circadian clock which is the 24h day and night cycle is having an effect on the psychological activity of all organisms. These processes involve activities such as the wave pattern of the brain, melatonin, and other biological aspects. Melatonin is a hormone in the brain that helps our body to control the sleep and wake cycles. A small portion of it can be found in some certain food such as meat and fruits. Our internal “clock” in our bodies that controls the sleep and wake cycles can also…

4 Tips to survive Daylight Savings with Children “Daylight Savings”… are curse words for moms along with “Time Change” and “Fall Back”. Two times a year, we feel the need to mess with our sleep schedules that we spend the rest of the year working to perfect so that mommies can have alone time, or clean up time, or even wine time., no judgment! I’m originally from the Saskatchewan myself, one of the few places in the world next to Hawaii that does not observe daylight savings. Our reason was…
