TANGLEWOOD MIDDLE SCHOOL 7 th grade science midterm exam study guide Name Test Date Period This study guide will outline the topics that will be covered on the midterm exam. Completing this packet will help aid in your success on the midterm. However, it is the student s responsibility to cover each topic in its entirety. You will need your science textbook pages (assigned during the semester), composition notebook (ISN), and science binder as a resource to complete this study guide. Notebooks/Binder should be taken home and used to study for this exam. Notebooks/Binder will need to be returned to the classroom the day of the test. Unit 1 Nature of Science Global interaction fosters our understanding of the natural world based on evidence discovered through scientific and technical innovation. 7.3 Scientific investigation and reasoning. The student uses critical thinking, scientific reasoning, & problem solving to make informed decisions & knows the contributions of relevant scientists. Students are expected to: (A) in all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student Evidence Law Theory Microscope: Know the parts of the microscope on pg. 4 of your ISN. The eyepiece of our microscope has a magnification of 10x. Find the total magnification below with each objective lens: 4x - 10x - 40x -
Unit 2 Building Blocks of Life Global interaction fosters our understanding of the natural world based on evidence discovered through scientific and technical innovation. SSCI.7.6A Identify that organic compounds contain carbon and other elements such as hydrogen, phosphorus, nitrogen, or sulfur. SCI.7.12C Recognize levels of organization in plants and animals including cells, tissues, organs, organ systems, and organisms. S SCI.7.12D Differentiate between structure and function in plant and animal cell organelles including cell membrane, cell wall, nucleus, cytoplasm, mitochondrion, chloroplast, and vacuole. SCI.7.12E Compare the functions of a cell to the functions of organisms such as waste removal. S SCI.7.12F Recognize that according to cell theory all organisms are composed of cells R SCI.8.5C Interpret the arrangement of the Periodic Table including groups and periods, to explain how properties are used to classify elements. Draw an atomic model of a Carbon atom: How many atoms of each element are present in each formula? Ex. CO₂ - Carbon = 1, Oxygen = 2 Formula: What element has to be present in a compound in order for it to be classified as organic?
Cell Theory: 1. 2. 3. What did the following scientist contribute to the discovery of cells and the Cell Theory? Robert Hooke- Matthias Schleiden- Rudolf Virchow- Theodor Schwann- Define the following vocabulary words: Prokaryote Eukaryote- Homeostasis- Photosynthesis- Know the levels of organization in order from least to most complex and what each level means. Organelle Cell Tissue Organ Organ System Organism Which organelles are found in plant cells that are not found in animal cells? Why is the Endoplasmic Reticulum rough and smooth?
Organelle Cell Wall Cell Membrane Location (Plant, animal, both) Function Nucleus Cytoplasm Mitochondria Endoplasmic Reticulum Organelle Golgi Bodies Ribosomes Location (Plant, animal, both) Function Vacuoles Lysosomes Chloroplasts Label each part of the cell and know their functions.
Unit 3 - Genetics The system of identifying relationships between inherited traits and patterns in genetics instructions connects one generation to another. SCI.7.14A Define heredity as the passage of genetic instructions from one generation to the next generation. Know the following terms: Trait Heredity Chromosomes Genes Gregor Mendel Genotype Phenotype What is the difference between a dominant and recessive gene? What is the difference between a homozygous and heterozygous genotype? In a certain species of plant, the color purple (P) is dominant to the color white (p). Complete the Punnett Square and show what the probability of an offspring being white would be? Plant 1 genotype PP (homozygous dominant) Plant 2 genotype pp (homozygous recessive)
