DNA and RNA
Tenth graders research the history and discovery of DNA. Using their text, they label a basic DNA structure and the composition of genes. They explain how RNA and DNA differ from one other and discuss the processes of transcription and...
Science 4 Inquiry
The Monster Mash
Young scientists create monsters by applying their knowledge of transcription and translation. They randomly find the DNA, assign it a codon, and build monsters piece by piece.
Curated OER
Producing a Strain of E. coli that Glows in the Dark
Students observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...
Curated OER
Constructing a Phylogenetic Tree
Students are given the opportunity to analyze DNA sequence differences between organisms in order to establish a reasonable picture of the evolutionary relationships between them (Phylogenetic Tree). In the simulation form they are...
