Marker pen

ethanol and 25% ethyl acetate. 2. Which pen matches the unknown ink? Provide a clear list of arguments as to why you believe it is a match. Our group decided the pen was Vis-a-Vis wet erase marker for multiple reasons. This first reason was that the colors appeared very similar, as most other pens appeared very dark with shades of blue on the TLC, while Vis-a-Vis and the unknown marker were lighter and had shades of yellow and light blue. Our unknown pen

METHODOLOGY PARTICIPANTS The aim of this article is to investigate the frequency of DMs in the speaking of two groups of teenagers and adults. Two groups of teenagers and adults were randomly selected to this aim which their age ranges from 20 to 23 for the first group and 27 to 30 for the second. The selection of the participants was based on the point of comparing the frequency of the use of DMs between the group of teenagers and adults. INSTRUMENTS The instruments applied in this study

of the pens listed above; to determine which line or lines the termite prefers. Each termite was tested and documented.

For my science fair project, I figured out what solvent would work best to erase permanent marker. The solvents I tested were: lemon juice, vinegar, water, and rubbing alcohol. I tried each of these solvents on a permanent marker line on plastic, paper, fabric, and wood. In this research paper, I will be talking about what a permanent marker is, how they are made, why they work so well, what rubbing alcohol is and its common uses, what vinegar is and its common uses, what water is and why water is

by a pen. 19 out of 28 termites tracked a line drawn by a PaperMate pen. 9 out of 28 tracked a line drawn by a Bic pen. Out of 4 termites used in group 7, only one tracked a line drawn, the utensil used was a red Bic pen. The data in table 2 shows that termites 1,3 and 4 did not track any one the lines drawn by any of the utensils. Only ¼ of the termites tracked a trail drawn by a utensil. Termite 2 being the only one that tracked a trail. The utensils termite 2 tracked were the: red Bic pen, black

fittest human races depended upon instruments of warfare, the pen, a tool not designed for combat, was declared "mightier than the sword" by Benjamin Franklin (World of Quotes, 2003). Ironically it was one of the first human weapons, the sharpened stone, that was a precursor to pen and paper when it was used to etch drawings upon cave-wall dwellings (Bellis, 2004). Long use of these concrete implements forged abstractions of them. Pen and paper have been interiorized into social practices and language

their bodies called pheromones. Because termites are usually found inside dark areas, pheromones help them communicate in these places. Past studies have suggested that ink inside ballpoint pens contains pheromones, causing termites to follow any trail created by the ink. If a pathway is drawn with an ink pen, then a termite will be attracted to the path and trace it due to the pheromones. To test the behavior of termites in relation with the presence of ink, we outlined two shapes with two different

years old, all I could think about was my family. How was I gonna go to school? Would I lose my friends? Would I ever see my brother again? I would write about my family breaking up. My writing was on a piece of printer paper with pens, (I wasn’t allowed to have markers at my mom’s house). She wasn’t home much so I would write about the boys she brought home. How some of them had tattoos and some of them had cool, funky hair. I was about 11 years old and my 5th grade teacher told me to write

which method is more beneficial to the facility. - The number of hogs that should be penned prior to the commencement of slaughtering since we have to take into consideration the number of pens in the plant, the number of hours to pen hogs prior to slaughtering. - How are we going to manage the plant number of pens to match up with the daily inventory so that the plant will run at full capacity? To do this, we must determine the number of hogs that should be penned prior to the start of slaughtering

What are the major 3D pen pictures? Description: Try and make easy 3D pen pictures at home in order to create different useful things that can be used in daily life. The decorative aspect of these objects can be easily taken care by 3d pens. Drawing is nothing but a fun game for creating arts.
