There are load of terms to know about DNA, and in this video we explain all the main ones - genes, alleles, homozygous and heterozygous, dominant and recessive, genotype and phenotype. Along the way we'll see how genes and inheritance really works!
How does gear ratio affect the speed of a model car? How can you find the best gear ratio? You should take this into account when building your own solar-powered car for a competition like the Junior Solar Sprint. See the Science Buddies website for an NGSS-aligned classroom lesson plan: https://www.sciencebuddies.org/teacher-resources/lesson-plans/solar-powered-cars-junior-solar-sprints?ytid=-frF3sPyKMI&ytsrc=description and instructions for an individual student science project:…
In this Biotechnology Project Idea, the Science Buddies Summer Science Fellows demonstrate how to construct your own gel electrophoresis chamber, the technology behind DNA analysis, and use it to compare molecules in different colors of food coloring dye. You can see the full science experimental procedure for this science fair project idea—and do it yourself!—in 'Forensic Science: Building Your Own Tool for Identifying DNA' project idea at Science Buddies:…
The Personal Genome Project, spearheaded by George Church, the Director of Harvard's Center for Computational Genetics, aims to recruit 100,000 people to offer up their DNA and personal life histories, all in an effort to further knowledge of human genetics and why we get—or don't get—diseases.
