Modeling Effective Dose: Salt Tasting lab Purpose The purpose of this lab is to see at what measurements (of salt) can the salt be detected by taste. Abstract The science of toxicology is based on the principle that there is a relationship between a toxic reaction (the response) and the amount of poison received (the dose). An important assumption in this relationship is that there is almost always a dose below which no response occurs or can be measured. A second assumption is that once a maximum

n this lab experiment factors that affected solubility are temperature‚ liquids‚ concentration‚ pressure‚ polarity‚ and molecule. In this experiment we use temperature‚ centrifuge‚ and concentration solutions to be able to achieve the results that we wanted. Step one of the experiment was to mix HCl‚ to cause a precipitation form‚ after that we had to decant the solution‚ then we used a centrifuged to separate the the precipitate of the supernatant liquid. After the decant was done‚ then the process

Based on the knowledge I gained from the blubber lab‚ I discovered how homeostasis is maintained by feedback loops in regards to blubber. A negative feedback loop is a process where change is prevented and a certain set point is kept. In this experiment‚ the negative feedback loop was the blubber preventing the changing temperature of the thermometer. Therefore‚ blubber is a method of homeostasis‚ because it prevents the ideal temperature of the thermometer from dropping. Our data shows this as well

Effects of Antiseptics and Disinfectants Purpose: The purpose of this lab is to discover substances that can slow the growth of‚ or kill‚ microorganisms. Hypothesis: The antiseptic that will prevent the growth of bacteria the most is iodine. The disinfectant that will prevent the growth of bacteria the most is bleach. Procedure: To begin the lab‚ turn the agar plate over and divide the plate into four quadrants and label the agar plate whether you

Electrostatic Lab What materials will you use? I will use the virtual lab and elements provided by the class What would you measure? I will measure the static electricity with a neutrally charged balloon What results do you expect? I expect that the balloons charges and sticks to the wall. What is the result are different? That would mean that there is a different way to charge the balloons than negative charge as using your hair. EXPERIMENT Bring together the balloons but not touching
