Purpose: We are doing this experiment to find the best ratio of potassium nitrate to powdered sugar for a model rocket motor that will create the most thrust. We are also testing if adding fins will affect the flight distance of the rocket. Hypothesis: The best ratio for potassium nitrate to powdered sugar is 1 to 3 because Grant Thompson‚ who has experimented with the best ratio of powdered sugar to potassium nitrate‚ has stated that “The 1 to 3 ratio is best for creating the most amount of thrust

Conductor Investigation Experiment LabReport Introduction This experiment is about to test how will the nichrome wire effect the ampere of the electric current. All the possible factor that will effect to the volt of the current • The Length of the wire • The Diameter of the wire • Temperature • Magnetism Aim To determine the effect of the length of the wire on the ampere of the electric current. Hypothesis Nichrome is an alloy(a metal made by combining two or more metallic elements)

Physics 1003 Experiment Report In this experiment‚ the technician began with the demonstration of solar energy. Solar energy is the conversion of light energy to electrical energy by using solar panels. Solar panels are devices that contained solar module which use light energy from light to generate electricity through the photovoltaic effect. And photovoltaic modules generate electricity from a frequency of light. From my observation of the experiment‚ I found that the panel is black in

Catalase Experiment Research Question: How does the weight of a piece of liver (0.4g‚ 0.8g‚ 1.2g and 1.6g in this case) affect the amount of gas created after 2 minutes when combined with hydrogen peroxide? Aim: To see find out how the amount of catalase correlates with the amount of gas created when in combination with hydrogen peroxide. Materials: 15g of liver 25 ml of hydrogen peroxide 1 scale 1 bucket 1 100ml graduated cylinder 1 250ml flask with bung 1 50cm tube (able to fix onto top of flask)

For this experiment‚ we started off by taking tubes numbered 1-4 and started adding one scoop of our enzyme catalyst‚ in this case‚ the yeast. We then proceeded to measure and add 1 mL of distilled water to test tubes A-D. To get a more accurate measure of 1 mL of distilled water‚ we used the dropper labeled “W” to drop distilled water into the 5 mL graduated cylinder until we saw that the bottom of the water line reached closely to 1 mL. Next‚ we took the four tubes with the scoop of yeast and

HYPOTHESIS Using train conductors as representatives for all of human kind we can postulate with some accuracy the percent of the population of Earth that are complete and total assholes. If you have ever lived in a small town with train tracks running through it you will know that the conductor of the train is required to sound the whistle at every crossing. This is a 4-part whistle; 2 long‚ 1 short‚ 1 long. My hypothesis is that we can calculate what percentage of the population of planet Earth

PLANT GROWTH EXPERIMENT Numerous environmental variables influence plant growth. Three students each planted a seedling of the same genetic variety in the same type of container with equal amounts of soil from the same source. Their goal was to maximize their seedling’s growth by manipulating environmental conditions. Their data are shown below. Plant Seedling Mass (grams) Day 1 Day 30

Lab Report - Microbes Aim: To investigate four areas of the school and to find out which of the four have the most microbes. Areas to Sample: 1. Girl’s locker room (Senior school) 2. Girl’s locker room (Elementary school) 3. Boy’s locker room (Senior school) 4. Boy’s locker room (Elementary school) Hypothesis: We predict that the boy’s locker room in the senior school will have the most microbes. First of all‚ there are more people using our locker rooms in the Senior School
