![]() | Use of Quartz Crystal Microbalance to Study Antibody Antigen Interactions ![]() The Quartz Crystal Microbalance (QCMB) is a simple device. The adsorption of a compound on the quartz surface causes a decrease in the resonance frequency that is proportional to the mass adsorbed. My goal was to use the QCMB to prepare a biosensor capable of measuring baculovirus particles. | ||

![]() | What effects would changes in the ozone layer have on Antarctica's penguin population? ![]() The penguin population in Antarctica is diminishing. Scientific teams have already investigated predator-prey relationships, disease, and environmental pollution as possible causes. Data has been collected and analyzed. No correlation has been found between these factors and the penguins' decline. The International Symposium on Environmental Issues is meeting late next year in Sydney, Australia. E | ||

![]() | High-Ampere Magnetism! There are a number of science museum exhibits which require many tens of
amperes of electric current in a thick cable to generate strong magnetism.
One example is a raft of compasses with a 200-amp cable running through
the center of the raft. Or, three 100-amp cables with three-phase AC
powering them, where the resulting field rotates and can spin a conductive
object by induction.

![]() | How to make your own comet In ancient times, people did not understand the objects in the sky, how they moved or what they were. They did not know what a comet was, where it came from, or where it went. A large comet is a spectacular sight and inspired both awe and fear in primitive peoples. | ||

![]() | Which string is the strongest and the least elastic? I wanted to know which type of string will stretch the most? I want to find out which string is the strongest and the least elastic. My hypothesis is that nylon thread will hold the most
weight and stretch the least.

![]() | What Patterns Are Formed When Number Sequences Are Translated into Different Base Systems and Interpreted in Base-10 The goal of my project was to find and study patterns formed through the translation of the first thirty terms of figurate number sequences into bases-2 through 20 when the results of these translations are interpreted in base-10. I hypothesized that I would find patterns related to the original sequences. | ||

![]() | How much does a typical student know about endangered species? We would like to do a survey research project on student knowledge about endangered and extinct animals. Our hypothesis states that the majority of the responses to the factual questions on the questionnaire will be correct. | ||

![]() | How does a bar magnet's field interact with the earth's magnetic field? The magnetic field around a permanent magnet, like the gravitational field around a massive object, is not only invisible, but hard for students to comprehend. With no concrete experience to draw from, they tend to ignore this basic concept, or at best, memorize facts about it. This activity shows how to map a magnetic field, and to find how a bar magnet's field combines with the Earth's magnetic | ||

![]() | Which types of film are most tolerant to light? The purpose of this experiment is to determine what film speed is most tolerant to light out of three speeds of film. (100, 400, 1600 speed film) | ||

![]() | How much do students know about pollution? We would like to do a survey research project to find out what students know and feel about air pollution. Our hypothesis states that the majority of the responses to the factual questions about air pollution on the questionnaire will be answered correctly.
