Which wood burns the fastest? In my research I found that because of the lower density of soft woods they burn more quickly than hard woods. When looking for a fast burning wood, I found most sources recommend using soft wood. I also found that the more resin (also referred to as sap) types of wood contain affects how it burns. The combination of high resin content and low density means easy ignition and a lesser burn time.
B. Hypothesis: My hypothesis is that pine will burn the fastest because it is less dense. II. Methodology: A. Variables: Independent Variable: Types of wood (poplar, oak, and pine.) Dependent Variable: How fast the wood burns. Controlled Variables: Size of wood samples, tempter of fire, method of ignition, shape of wood samples.
Major League mandates wooden bats simply because the aluminum bats can make the ball so dangerous. The cost of a wooden bat is relatively low compared to an aluminum bat. A good wooden bat can be purchased
As the solvent moves up the paper, it carries along any substances dissolved in it, which are the pigments. The heavier the pigments the slower they move and they do not travel as far. Going in order from the heaviest to the lightest: Chlorophyll b, Chlorophyll a, Xanthophylls, and Carotene, which means that the lighter the pigment the better the substance is in dissolving in solvents. Photosynthesis
Fill the cuvette about 3/4 full of the solution you wish to test. Wipe the outside of the cuvette with a soft tissue (Chemwipe) to remove any moisture or fingerprints from the outside
Slowly pour the beaker contents into the drip paper. Make sure every piece is out of the beaker. 10. Remove the funnel from the drip and the filter paper from the funnel. Allow the filter paper to dry overnight.
Then the same was done with each of the other substances. Weezie was washed off with water after the baking soda. Next, the tray was washed and dried. Then, using the spatula again a small amount of orange juice, molasses, veggie oil, and vinegar was placed in each corner of the dissecting tray. Weezie was placed near each substance again to be observed.
Hemp fiber could be used to make a large variety of papers, which would help decrease the paper industries dependency on wood. Hemp based building materials have proven to be a direct, and even sturdier replacement for wood in construction. With hemp’s many different uses, the saying should go “Hemp is
Allow the test tube to cool and record your observations. 5b. After the test tube has cooled, add 5-10 drops of water and record your observations. 6. Obtain 6 clean/dry test tubes and arrange in your test tube rack.
He compares the use of hemp compared to wood. Dean Curran writes, “Hemp produces twice as much fiber per acre than the average forest. When added with worthless fibers that are currently burned such as straw from oats, rice and wheat, hemp can be used to create construction materials stronger than lumber” (Curran). So not only can hemp produce more paper then wood it also creates construction materials stronger than it as well. Lots of things are made from wood everyday but it has nowhere near the same production that hemp has.
