In this lab‚ the purpose was to find how mass‚ angle‚ and length affected the average period that it took for a pendulum to swing eight times. For each experiment‚ the pendulum had two constants either being the mass‚ angle‚ or length and had one variable being changed‚ also being either the mass‚ angle‚ or length. In each experiment‚ the pendulum took ten full swings and at the end of the tenth swing‚ the time was taken. Then‚ the time of the ten swings was divided by ten and an average period

The overall experiment consisted of three smaller experiments as a result of the different properties chlorophylls possess and the need to test them individually to receive the most accurate results. Preparation for the lab began with selecting a medium to large spinach leaf and deveining it. Once the spinach was prepared‚ it was ground in 5 mL of 100% acetone‚ creating a green acetone extract. The extract was filtered through a funnel with a kimwipe and into a test tube. The volume of the filtered

Animal rights groups have surfaced throughout the years‚ protecting the lives of innocent animals from experiments. Below are some facts about how experimentation on animals is torturous: “1. Over 100 million animals are burned‚ crippled‚ poisoned‚ and abused in US labs every year. 2. 92% of experimental
