A number of different variables, such as the concentration of the hydrogen peroxide solution or the temperature at which the reaction occurs, can affect the rate at which yeast breaks down hydrogen peroxide. To prove this we first tested the solution with 3% concentration of peroxide, the paper that was soaked in yeast rose in 1.7 seconds. After that we changed our concentration to 2.25%, 1.5%, and .75% of hydrogen peroxide to see the effects it had on the amount of time it took the felt to completely drop and rise. On 2.25% it took 2.8 seconds, 1.5% took 3.2 seconds, and .75% took 3.9 seconds.…
On January 10th, 1901, 10:30 AM, possibly the biggest and most influential events in all of oil history occurred in Beaumont, Texas. The Texas Oil Company, now known as Texaco, struck oil at a salt dome in southern Beaumont Texas. This was the biggest amount of oil the world had ever seen at the time. These wells on Spindletop would change the way we drilled, collected, used, and sold oil. Spindletop even raised concerns about conserving the oil. This gusher would change the way oil was drilled, collected, used and sold. The Spindletop oil field produced more than 20% of the United State’s oil at that time. Spindletop has an intriguing story that expands before and after the actual gusher, and that story involved many people…
The red knot (Calidris canutus) or the rufa red knot (Calidris canutus rufa) is a medium sized shorebird, the second largest sandpiper (Calidris), measuring between 25 and 28 cm long with a wingspan of approximately 20 inches (United State Fish & Wildlife Service (USFWS), n.d.). (See Figure 1). The species has been known to travel great distances; breeding in the Arctic regions of Canada and migrating south in the winter months to the coastal mudflats and tidal zones (USFWS, n.d.). Every spring the red knot reaches the beaches of Delaware Bay with very little body fat and for three short weeks forages on the highly nutritious eggs of horseshoe crabs before they continue migrating north to the Artic (Karpanty, et al., 2006). (See Figure 2). This…
Women sought for liberty and equality that was granted to men during the early nineteenth century in the United States. Women questioned differences in rights and roles compared to men. Sarah Grimke was the daughter of a wealthy slave-owner in Charleston, South Carolina. She despised slavery and inequality of women and moved to Philadelphia. She became a Quaker and leader for abolition and women’s rights. Sarah Grimke published Letters on the Equality of the Sexes in 1838 that criticized inequality of women. However she believed achieving equality of the sexes was possible. She argued that God had made both genders equal, but men created inferiority among women and denied them opportunity. She insisted that women gain rights and duties to be able to participate in education, religion and urged that marriage should not limit women’s rights. She believed Americans could achieve equality of the sexes by allowing women to get equal educational opportunities, holding rights during marriage equal to men, and by receiving equal salary as men.…

Sensory play and sensory devices have been around for a while now, and have been manufactured in order to help create a sensory input to calm and focus children with ADHD, ADD, or autism. Furthermore, are fidget spinners productive or are they just a distraction. Now, I tend to fidget a lot, I press my fingers against my palms, twiddle my thumbs, and sometimes, have a hard time focusing. This is only when i’ve been sitting a desk for a while, and I constantly feel the need to be doing something productive, or I feel like i’m wasting my time. The science behind fidgeting actually isn’t very complex. Said by Roland Rotz, “If something we are engaged in is not interesting enough to sustain our focus, the additional sensory-motor input that is mildly stimulating, interesting, or entertaining allows our brains to become fully engaged and allows us to sustain focus on the primary activity in which we are participating.” For example, If you are fully engaged in watching a baseball game in the bottom of the 9th, I’ll bet you're not fidgeting a lot because you're focused…

The supplies needed in order to create this bracelet are rubber bands, a loom kit, and a Rainbow Loom hook. When all the supplies are prepared, it is time to start. First, make sure that the red arrow is facing outward. Also, make sure that 25 rubber bands are supplied, with at least two different colors. Take a rubber band and wrap it around the first middle peg. Stretch the other end diagonally to the first right peg. Next, take different color band and wrap one end around the first right peg that one end of the first rubber band is wrapped around. Pull the other end diagonally onto the next middle peg. Continue this process until the end of the loom kit is reached. At this moment, flip the loom kit so that the red arrow is now facing inward at the top. Now it’s time to use the loom hook. Pick up the bottom rubber band from the first peg from the top that has two rubber bands on it. Once it is on the hook, take it off the peg it’s on and wrap it around the peg in the middle that the other end of the rubber band is already on. Note that the rubber band that was just on the hook should now make a tear drop shape. At this instant, pick the bottom rubber band off the peg that was just used, and wrap it around the peg the other end of the rubber band was on. Repeat this step until the bottom of the loom kit is reached. The next step is to pick both layers of the last rubber band and pull it out to the peg in the empty row of pegs. Notice that there are two layers of the band because in previous steps the band was wrapped around the peg twice. After it is pulled out, take a c or s clip and put it on both layers of the band. Pull the rubber bands of the peg by pulling the end up. Finally, put the clip on the other end of the bracelet. The…

First, prepare the equipment. The equipment you need are colored-papers scissor, needle tool, and glue. Second, make the quilling strips. You can make it by yourself. Cut the colored-paper into particular sized paper. You can cut the paper into 1 cm wide each pieces. It depends on the shape you are going to make. The third, roll the paper strip by using needle tool. Keep rolling the paper strip until the whole quilling strip is rolled around the needle tool. Next, pull off the roll. When you have rolled the paper strip, take it off. If you want a loose roll, put it down and let it lax by it self. After that, glue the paper together. You can use stick or toothpick to stick on the glue. Next, pinch the roll into the shape that you want. For example, if you want to make a leaf, just pinch the tip of the roll.
