Using three-dimensional scaffolds, these materials address the following topics:  - Relationships between DNA, proteins, and traits.- How mitosis enables each cell to receive a copy of DNA.- How gametes like sperm and eggs are formed and transmit parents' genes to offspring.  - Predicting traits based on parents' genotypes and phenotypes using Punnett squares.  Each packet is broken into five parts - data dive, core ideas, investigations, asssessments, and life connections. Formative assessments and checkpoints are embedded throughout each packet. The final packet prepares students for a summative assessment, with a provided practice assessment.Implementation instructions are embedded for each component of each packet. PDFs are included as attachments (in case the file formats are altered by this system).
