The wheelchair experiment introduced me to a world that I have never known. I have never been in a wheelchair or been affected by any form of hearing‚ visual‚ or physical disabilities. So‚ this experiment caused me to really think about how the layout of a space‚ weight of doors‚ etc. could affect someone. While using the wheelchair‚ I felt as if I was in the spotlight every time I entered a room or crossed paths with a group of individuals. People would look on as I posed in the wheelchair and give

Should we use animals for experiments? (against) The question is‚what it means to use animals for experiments? It means‚ the investigators and doctors whose are producing medicines they have to test is first‚somehow‚to see how is the effect of the medicine.This “somehow” means the animals.Moreover I haven’t said anything about testing new products like cosmetic products‚make-ups‚sprays. In my opinion‚the animals are different‚they body and organism are different.For this reason the scientists

a tremendous variety of oxidation states that appear in its compounds. The oxidation numbers range from Mn (III) in compounds like Mn(NO)3CO to Mn (VII) in KMnO4. Compounds of manganese range in oxidation number between theses two extremes. This experiment involves the preparation of a Mn (III) complex of actylacetone (also named 2‚4-pentanedione) which is a useful starting material for the preparation of other Mn (III) compounds. Manganese (III) complexes are relatively stable and can be prepared

Osmosis Experiment Subject: Professor Egg-avier Duration: 3 weeks (Oct 2nd – Oct 16th) Week 1 On October 2nd my group was giving a raw egg (weighing 58.8 grams) and placed it into a clear mason jar with 200mL of vinegar. The ph levels of our vinegar equaled a 2 which tells us that vinegar is a fairly acidic liquid. Once submerged in the vinegar‚ little bubbles began to appear around the egg’s shell. We believed this to be carbon dioxide escaping from the shell. We left our egg to sit in the

Observations of Chemical Changes Purpose: To observe some properties of chemical reactions and associate them with everyday household cleaning products. Procedure: In order to complete this experiment‚ I had to set up and organize my lab table. I used my 24-well plate‚ my 96-well plate‚ and the first experiment bag which included all of the necessary chemicals. I also had to gather 3 household cleaning products and a pipet in order to test them as well. The procedure involved was putting 2 drops of

For Acidic hydrolysis‚ SAC was found to be well susceptible to acid hydrolysis with 0.05 M HCl at 40 ˚C for 30 min caused about 8% reduction in the peak area of SAC (Fig.4a). While this mild condition didn’t affect VAL. While‚ nearly 27% was the reduction in SAC’s peak area when subjected to alkaline hydrolysis. This considerable decline in the peak area of SAC when subjected to 0.01 M NaOH at 40°C for 30 min revealed degradation products peaks appeared at 3.339 and 9.482 minutes (Fig.4b) and they

The cerebellum of the brain‚ the “little brain”‚ is located at the rear of the brainstem. The tissue is folded into itself several times and each layer helps with the organization on the mind. It is clear that the cerebellum has an essential job because over time it has grown‚ by studying fossilized skulls it has been exposed that the cerebellum has increased to three times its size over the past million years. This small lump of tissue was first discussed by Ray S. Snider in an article written
