Test tube

filled dialysis tubes fill with different percentages of solute and placed them in beakers full of a different solute. Through this experiment, I saw what happens when the solution becomes hypertonic, hypotonic, and isotonic. My hypothesis was that bag A would shrink because the water would leave the bag to go to the higher concentration. Bag B would stay the same because it would be isotonic. Bag C and D would swell because water would rush into the cell where…

is to outline the process of planning an activity in science understanding physical science for a 5 year old child with the expectation of learning the concept of motion, inertia, force, velocity, acceleration and gravity by using balls, blocks and tubes. The report will also outline the pedagogy approach adopted by educators to ascertain that the child will engage in a physical science activity, which will improve the child’s skills of problem solving, critical thinking and reasoning in…

They discovered a form of testing called in vitro which was based on human cells using robotic screening (Bin, A264). Through this method, human tissue is grown in test tubes which are then exposed to the new substances being tested (Cole). Test tube testing eliminates animals from being poisoned in order to differentiate toxic from non-toxic ingredients (Cole). This artificially grown tissue has proven to have more accurate results in testing irritation…

separate tubes. Next, we used a sterile loop to transfer two to four larger bacteria colonies from an E.coli plate into each of the two tubes. The bacteria was observed under UV light to make initial observations. We pipetted 10 ul of pGLO plasmid (0.08 ug/ul) into one of the tubes. Both tubes were incubated on ice for ten minutes. After ten minutes of incubation, the tubes were heat shocked at 42°C for exactly 50 seconds and then returned to ice. After two minutes on ice, we removed the tubes,…

In these camps “the death rates were so high, from malnutrition, typhus and exhaustion that the disposal of corpses became a serious problem.” (THE CAMPS) The treatment in transporting and caring for the victims is probably one of the main factors in the dehumanization of people during Holocaust. The victims were treated inferior simply because of their nationality. The Nazi’s made it a point to degrade these people in every way possible by taking away their rights and free will.…

When we finally arrived at the water’s edge my brother John and I were so excited, we basically leapt out of the car before it came to a complete stop. Larry and my uncles unloaded the cars, while my Aunt Janet and Sister Lorena went to pick up the tubes. John and I decided to jump in the water to cool off while everybody else got everything ready for the trip down the river. We were all laughing and smiling all the while oblivious to the impending tragedy that lies ahead. The moment I jumped…

My friends and I consider ourselves to be very spontaneous and adventurous. It was one cold week in February of 2016, when a group of about 6 of my friends (including me) all decided that we wanted to go to Vermont for the weekend to ski and snow tube. Considering this would be my first trip with no parental guidance at all, I was apprehensive about asking my mom. On the way to drop me off after school one day, my best friend Tony told me to tell her that he was going too so then she’d say yes…

Determination of Most Advantageous Sequestering Agent By: Kayla Jeeter and Ashley Driscoll Chemistry 112-508 Abstract The creation and execution of this project served to determine what material is a better sequestering agent of the polycyclic aromatic hydrocarbons (PAHs) that are found in Texas’ water. Charcoal is currently the most typical agent used to sequester PAHs. In this experiment, two different Bentonite clays (zeolites) were synthesized, one magnetized and one not, to determine if…

Spina Bifida, a condition that is classified as a neural tube defect that affects about 1,500 babies are born with each year where the spinal column is not completely closed over the spinal cord. There are two types of Spina Bifida, one being very mild and one being very severe. Although this can be a tough disorder with possible physical and mental disabilities, with the correct treatment and follow through many people with some assistance cam live their lives fully. Spina Bifida can vary in…

Spina Bifida (Ridosh, Braun, Roux, Bellin and Swain (2011) state “Spina Bifida is a chronic congenital health defect caused from the incomplete closure of the neural tubes of the spinal cord during the first few days of development. It occurs in almost two out of every 10,000 births.” According to the Spina Bifida Association of America, (2014) there are four different types of Spina Bifida. The first one is, Occult Spinal Dysramphism (OSD). Children born with this particular form of the…
