Unit Title: Cells & Heredity 7th Grade Science Stage 1 - Desired Results Established Goals: Know and apply concepts that explain how living things function, adapt, and change. State Standards: 12 A Enduring Understandings: Students will understand that… • Compare and contrast the organization of a living system (cell, tissue, organ, system) to another system. • Compare unicellular and multicelluar organisms. • Compare and contrast meiosis and mitosis. Essential Vocabulary: Cell Cell Membrane Organelle Nucleus Cell Wall Ribosome Endoplasmic Reticulum Mitochondria Golgi Bodies Lysosomes Vesicle Vacuole Cytoplasm Chloroplast Tissue Organ Organ System Organism Unicellular Multicellular Essential Questions: 1. How do simple life structures compare with complex life structures? 2. Why does an understanding simple life structures help us understand complex life structures? Amoeba Diffusion Osmosis Passive Transport Active Transport Endocytosis Exocytosis Photosynthesis Cellular Respiration Fermentation Cell Cycle Chromosomes Homologous Chromosomes Mitosis Cytokinesis Interphase Prophase Metaphase Anaphase Telophase Meiosis Heredity Self-pollination Cross-pollination Dominant Trait Genes Alleles Phenotype Genotype Punnett Square Mendel Pedigree DNA Nucleotide Mutations Adapted from Understanding by Design: Professional Development Handbook. McTighe and Wiggins. ASCD. 2004. Resultant Skills & Knowledge: Students will be able to 1. Determine the identity of several organisms using the dichotomous key. 2. Infer what biome or ecosystem you might find a variety of organisms living in based upon their observable structures. 3. support with evidence why an unknown cell should be classified as a plant or animal cell based upon observation of its characteristics. 4. Determine how our understanding of DNA has revolutionized a field (Example: criminology) 5. Explain that one or more genes determine an inherited trait. 6. Determine traits of an offspring based on Punnett square analysis. Support determination of traits with evidence. Stage 2 – Assessment Evidence Performance Tasks: Through what authentic performance tasks will students demonstrate the desired understandings? • Students will create an analogy project to demonstrate their understanding of cell structure and function. • Egg-Speriment (Diffusion & Osmosis) • Microscope: Live & prepared samples • Photosynthesis lab • Heredity Project Other Evidence: Through what other evidence (e.g., quizzes, tests, academic prompts, observations, homework, journals) will students demonstrate achievement of the desired results? • Review of Dichotomous key • Viewing pond water samples • Cell Organelle Quiz • Cell Processes Quiz • Microscope journal drawings • DNA Lab • Punnett Square Quiz • PTC Heredity Activity Stage 3 – Learning Plan Learning Activities: Adapted from Understanding by Design: Professional Development Handbook.
