Rubber Boom Slavery Dating back hundreds of years the indigenous people of South and Central America had discovered the many uses of rubber‚ taken from what is known as a "Hevea brasiliensis" or more commonly‚ a rubber tree. When the latex is extracted from the tree it is hardened and formed into rubber which natives would use for numerous tasks such as making shoes‚ handles for tools‚ and even rubber balls for sports (Dean 23). Due to its useful yet uncanny features it created an immediate

Karol Mooshe Literature Review Rubber vs. Rubber The purpose of my experiment is to figure out which type of synthetic rubber is best to use on bicycle tires‚ neoprene‚ latex‚ or silicone. Synthetic rubber is a polymer. A chemical compound that includes many molecules that form one large molecule. Synthetic rubber is also an artificial elastomer‚ a material that undergoes elastic deformation under stress‚ but then turns into its original shape. In

measuring its mass and volume. Hypothesis When the rubber stopper is dropped into the overflow can‚ the volume displaced (mL) will be equal to the number of grams of the rubber stopper. I think this will be the outcome because I learned before that 1g=1ml‚ so for every gram dropped into the overflow can‚ 1 ml should be displaced (the volume). Therefore I think the density of each rubber stopper would be 1g/ml. Materials - 5 different rubber stoppers - Triple Beam Balance - Graduated Cylinder -

Newton’s first law totally connects with our Rubber Band boats. When the boat was in motion‚ it continually stayed in motion. When the boat was at rest‚ it stayed at rest. For Newton’s Second Law it states: The acceleration of an object as produced by a net force is directly proportional to the

next quarter to spend for buying two important materials in manufacturing tires‚ Natural Rubber and Carbon Black. Natural rubber is the basic elastomer used in tire manufacturing then synthetic rubber is often added by manufacturers to reduce cost. To avoid loss of quality‚ Carbon Black is then added which gives the final product reinforcement and abrasion resistance‚ it forms a high percentage of the rubber compound. Both can only be bought overseas‚ though Carbon Black supply is readily available
