The experiments included chemical and physical reactions dealing with torn news paper‚ appearance of rock salt crystals‚ the appearance of sand‚ oil and water on plastic‚ and making iodine in water and mineral oil. We found that all these included four physical changes and two chemical changes. This was important in determining the substance or mixture that dealt with physical and chemical properties as well as homogeneous and heterogeneous mixtures. Purpose/Hypothesis: The purpose

diffusion of water across a semi permeable membrane. Over three days we tested the egg in three different solutions to observe the changes. On Day 1‚ the main question we answered was what happened to the egg when it was placed in vinegar? Before doing this I came to my hypothesis was that the vinegar would eat away at the shell and eventually dissolve the shell since it is an acidic solution. Things with acid are corrosive and sometimes poisonous so they eat away at things. On Day 2‚ the main question we had to answe

plants may have a hard time penetrating the soil due to the heavy compacting in the clay (Royal‚ 1). Usually clay is very high in PH (alkaline)‚ which can be hard on plants as they are trying to attain enough nutrients to grow (Bachman‚ 1). Our hypothesis for this experiment was that if there is more clay than soil in the mixture‚ then there will be less plant growth than if the majority of the mixture was soil. METHODS: Materials used throughout the experiment: 2- plant seeds 1- plastic

to pass through. I will keep the surface area the same by keeping the mass and length of the potato piece the same in each instance‚ by measuring and cutting it carefully. I am fairly sure that my results are reliable as they proved my hypothesis but I had two anomalous results. I think this is because as we did the experiment over 3 days‚ we did not have a chance to use the same potato as I had planned to do. All potatoes do not have the same tissue structure and also concentration

In the process‚ the paper also clearly explains the various key factors which determine the outcome and accuracy of the method of experimental research‚ such as dependent

recreate the Redi experiment that was preformed originally in 1668 by disproving the spontaneous generation of maggots on meat. In this experiment there were steps that first had to taken. Step1. Observation: Step2. Ask Questions: Step3. Develop a Hypothesis: Step4. Make a prediction: Step 5. Perform experiment: Step 6. Collect results: Step 7. Interpret results and make conclusions. This was done by placing meat inside two jars and observing What would happen over the course of 4 days to the meat

from the observations that initially‚ the increase in exercise did not increase the performance of the subjects. However‚ after trial three (after 60s) two of the subjects increased their mathematical performance. (Graph attached) The predicted hypothesis was correct as brain performance increased through exercise. However‚ this was not clear in the observations because as soon as exercise began‚ the blood with the oxygen immediately went to parts of the body that was doing the work (here‚ the legs)
