Throughout the experiments the size of the balloons stayed about the same size except for in experiment 3. Also the bottles that had more sugar had a stronger scent of alcohol and also contained more foam on top of the liquid. All yeast in each of the bottles seemed to have fermented at the same time and stopped/slowed down‚ the growing process‚ at the same time. Bottle 3 also would always overflow and the foam would fill the ballon in every experiment. Another trend with bottle 3 was that in the

Determine the weight and volume of the cylinder (for lab experiment written on side). 2. For the mixed aggregates ensure they are well mixed. Now fill the cylinder with the aggregate to 1/3 the height of the cylinder using the scoop. 3. Compact the aggregate with the tamping rod giving 25 strokes without

Experiment 4A – Counting Atoms in a Chemical Reaction Purpose: The purpose of this lab is to create an experiment where zinc reacts with hydrochloric acid in order to find out the number of moles and atoms of zinc reacted. This can be accomplished by weighing the sample before and after the reaction with hydrochloric acid. Data: Material Mass in grams (g) Initial mass of dry beaker 49.37 Initial mass of dry beaker + zinc 51.03 Initial mass of zinc 1.66 Final mass

the okay to do the experiment‚ I grabbed the girls and went to work. The experiment I picked was the conservation concept‚ where the idea that merely changing the appearance of objects does not necessarily change other key properties. In other words‚ just because I put the same amount of water in a bigger case‚ doesn’t change how much water there is. I predict that both the girls would fail at conservation concept‚ and always

Are you looking for a fun experiment that you can perform for a psychology class? This experiment on gender and memory is relatively quick and easy to perform‚ which is a bonus if you are short on time and resources. Could gender differences play a role in short-term memory? We often hear women complain that their husbands can’t remember important dates like anniversaries or birthdays‚ but could this phenomenon be due to something like memory differences between men and women. Some previous research
