The purpose of this experiment is to observe the results of cellular respiration of yeasts, using grape sugar as a substrate and yielding carbon dioxide and ethanol.

Using equipment that we might now call simple or even rudimentary, Galileo revolutionized basic scientific principles which were posited by Aristotle and held firmly by scholars of the High Middle Ages and Renaissance. One of his most important experiments was the inclined plane experiment. Galileo used his inclined plane, a simple board with a groove down which he rolled a small metal ball, to ex

This page presents a "basement science" experiment which reveals the universality of gravitation by demonstrating the gravitational attraction between palpable objects on the human scale. The experiment deliberately uses only the crudest and most commonplace materials, permitting anybody who's so inclined to perform it. Einstein's 1915 theory of General Relativity explains gravitation

Satellites are used to monitor the condition of the earth's surface over large areas in a short time period. Images from satellites have been used to determine changes in global vegetation patterns, monitor the health of agricultural crops, and measure the amount of evaporation from the earth's surface. The pictures from satellites are not taken with a traditional camera that requires film. Instea

The purpose of this lab is to demonstrate visible changes in E. coli bacteria that have been transformed with a gene that codes for a green fluorescent protein, the source of this gene being bioluminescent jellyfish. In real life, the gene provides the jellyfish with a glow-in-the-dark feature in the deep, dark ocean. You will be using a plasmid called pGLO (p = plasmid) because the gene being

In this investigation, amylase is the enzyme, and starch is the substrate, i.e. the substance it acts upon. In fact this work should add to your knowledge about the process of digestion which occurs in your body. This practical work is designed to give you some experience about: i) how enzymes work, using amylase as an example ii) what a "control" experiment tells you iii) how to carr

The purpose of this project is to determine if there is a mapping between Nimbers (non-negative integers under Nim addition) and multidimensional objects called Simplexes, thus demonstrating the power of finite groups to relate very different mathematical objects to each other.

I wanted to demonstrate how parallax works in measuring distances on a small scale, and to see if one method was more accurate than the other. My hypothesis was that the tangent method would be more accurate than the radian method.

Light has a dual nature: it has the characteristics of both waveforms and particles. This science project was conducted in order to help us better understand the dual nature of light. This paper explains the double split experiment which is also known as Young's experiment, and how the experiment demonstrates the waveform nature of light.
