Sept.12‚ 2013 Experiment 1: SLIME (Starting Labs Is Mighty Exciting) Abstract In this experiment we investigate the properties of SLIME. Substitution of polyvinyl alcohol instead of Guar gum makes this experiment quite accessible. The Slime is prepared by mixing a solution of (Na2B4O7*10H2O) sodium tetraborate decahydrate (Borax) and H2O with a solution of polyvinyl alcohol (pva) and H2O. Then stirring for ~10 minutes to obtain the final product‚ SLIME. The product was examined and noted

The Effect of Physical Barriers On The Growth Of Polycephalum Nathan LHypothesis: The slime mould will attempt to bypass the barrier to reach the oats. Independent Variable: The path provided by the colored Lego blocks. Dependant Variable: The path in which the Polycephalum Constants: The size of the dish‚ the species of slime mold‚ the light the slime mold received‚ and the temperature it was kept. ] 1.

In today’s laboratory session you will examine some common molds and attempt to identify them. While the identification of bacteria relies heavily on biochemical testing‚ the identification of molds tends to focus on their structural features. You will examine the appearance of growing cultures of several different molds and then

experimentations the experiment of “Fluffy Slime” illustrates the science concept of chemistry. Fluffy slime isn’t the traditional sticky slime. This slime is soft‚ squishy‚ and fun to play with‚ while maintaining a solid form. There’s different ways to play with it‚ you can stretch it‚ squeeze it‚ bend it‚ and put it back together! Mattel first created slime. It was mostly made of guar gum (polysaccharide) and borax (sodium tetraborate). The non-toxic green slime was made in 1976. Due to the history

Kentaurus Webster Ms. Mulvanny 8th Grade Science December 13‚ 2012 What Causes Mold on bread? The question I am trying to answer is what causes mold on bread. I think that mold is fungus. Mold spores are everywhere: in the air‚ on your kitchen counters‚ on your skin etc. Mold likes to grow in environments where they can find nutrients like bread. When mold spores find a nice environment‚ they "hatch" and then begin to eat and reproduce. This is when you see the lovely green and white fuzz

Project Part A Question: Is white bread or wheat bread more resistant to mold? Food waste is a problem for families on a budget. So not taking into account any health benefits from a particular style of bread we want to know which bread is more resistant to mold or does it matter at all? A1. Literature Review According to a study by students at A&M University in April 2010 they found that white bread is far more susceptible to mold due to several factors. The most prevalent factors being that white

produce up to 10 parts per mold‚ as the mold will have defects after several parts has been casted. So‚ for a production of 100‚000 parts‚ a minimum of 10‚000 molds have to be manufactured. Also‚ only one part can be casted at one time‚ which highly slow the process of making all the parts. 2. Using the investment casting method‚ the mold too will have to use multiple molds to cover the quantity of 100‚000 graters. By looking at the size of the grater‚ we assumed that each mold can produce up to from
