BCR: Which Towel? A student asks a testable question: “Which brand of paper towel absorbs the greatest volume of water?” Design an investigation to provide an answer for the student. Be sure to include • the materials needed. • a numbered procedure. • the independent and dependent variables. • important data that will answer the question. • ways to help ensure the accuracy of the results. Materials: Several paper towels‚ a flat dish‚ bottled water‚ a thermometer‚ a tong

grave. Speeding increases the stopping distance required to avoid a collision even as it reduces the amount of time a driver needs to avoid a collision called the 3 second rule. For example when people are running late to work they tend to speed and are not as aware about the certain limit their meant to be driving‚ they speed and they don’t tend to give way especially to trucks and buses which causes a huge amount of collisions between the vehicles and when they want to brake it would be less likely

to conclude how long the reaction proceeds for. We tried the experiment many times with different amounts of chemicals. In this experiment we will be seeing how the amount of chemical change‚ will affect the timing of reaction to occur. The collision theory Some reactions can be slow such as rusting but some can be fast for example burning. Reactions that occur slowly have a low rate of reaction. Reactions that happen quickly have a high rate of reaction. For a reaction to happen the particles

for a chemical reaction to take place‚ the reactants must collide. The collision between the molecules in a chemical reaction provides the kinetic energy needed to break the necessary bonds so that new bonds can be formed. Thus‚ increasing the concentration of the anode‚ zinc sulfate‚ will increases the rate of reaction for oxidation because there are more zinc ions in the new concentration‚ which would also increase the collision between molecules. This will eventually allow an increase in the transferring
