What Sunscreen really works? Problem: Will sunscreen with an SPF of 4 be able to withstand the sunlight more effectively than SPF 45? Purpose: Due to the increasing amount of sun exposure on teens‚ we want to ensure that sunscreen can protect against the sun. An increase amount of exposure can damage the skin directly. The dangers of increased sun can lead to the 3 types of skin cancer (Basal‚ Melanoma‚ and Squamous) and these types can spread to other parts of the body. The most dangerous form

technique). Each group will inoculate his/her own plate of Mueller-Hinton agar with an assigned culture. To that inoculated plate‚ you will then aseptically add sterile filter paper discs (using a disc dispenser)‚ which contain a known concentration of antibiotics. As soon as the antibiotic discs touch the agar‚ the antibiotic will begin to diffuse into the surrounding agar. During incubation the bacteria you inoculated onto the agar

This is a quantitative test and is considered to be the gold-standard method for biofilm detection (13). Organisms isolated from fresh agar plates were inoculated in 10 mL of trypticase soy broth with 1% glucose. Broths were incubated at 370C for 24 hours. The cultures were then diluted 1:100 with fresh medium. Individual wells of sterile 96 well-flat bottom polystyrene tissue culture

quickly diffusion occurs is dependent on several factors‚ such as temperature‚ particle size‚ and the concentration difference on either side of the membrane. Testing the hypothesis relating to the effect of molecular weight to the diffusion rate‚ agar plate set-up was used to observe the diffusion of different substances. The methylene blue and potassium permanganate (KMnO4) was used and placed in the plate. Because the two substances have distinct colors‚ the measurement of the diffusion zone was

was in order to test the many effects of diffusion and osmosis amongst four experiments. One such experiment was testing the effects of molecular weight on diffusion in relation to the use of Agar. The methods performed included the use of two acids‚ HCl and acetic acid. Both acids were placed into an Agar-filled dish and‚ over increments of 15 minutes‚ data collection was taken based off the diffusion rate and the diameter length of both the HCl and the Acetic Acid. The resulting factor was the

____________________ ABSTRACT The effect of molecular weight on the diffusion of substances were tested through the use of agar-water gel with three wells placed in a petri dish. Drops of three different substances namely: Potassium permanganate (KMnO4)‚ Potassium dichromate (K2Cr2O7) and Methylene Blue were placed in the wells of the agar-water gel in the petri dish. The diameter of the diffused substance was noted every 3 minutes for 30 minutes. The Potassium permanganate (KMnO4)
