Science
DNA Structure and Replication: Build the Matching Strand
Students learn base-pairing rules, build complementary DNA strands, solve base-percentage puzzles and trace how DNA replication copies a molecule.

Science
Earth’s Biomes: Match the Climate to the Place
Students use a biome reference table to match climate clues, plants and animals to six major land biomes.
Science
Energy Flow in an Ecosystem: Food Chains and the 10% Rule
Students classify organisms as producers or consumers, calculate energy passed along a food chain using the 10% rule and predict the effects of removing one species.
Science
Energy Forms and Transfers: Follow the Energy
Students read about energy forms and conservation, trace energy transfers in six devices, and calculate wasted energy and efficiency.
Science
Evidence for Evolution: Bones, Fossils and DNA Differences
Students sort evidence for evolution into types, interpret a made-up DNA-difference table to rank how closely related animals are, and explain homologous and vestigial structures.
Science
Food Webs and the 10% Rule: Following the Energy
Students read about energy flow, learn the vocabulary of food chains, and use the 10% rule to calculate how much energy reaches each level of an energy pyramid.
Science
Four Big Molecules of Life: Read, Sort and Match
Students read about carbohydrates, lipids, proteins and nucleic acids, fill in a summary table, match examples to jobs and answer short questions.
Science
Free Fall and Projectile Motion: Two Directions, One Clock
Students solve free-fall and horizontal-launch problems, complete a motion table that tracks horizontal and vertical motion, and compare weight on Earth and the Moon.
Science
Free-Body Diagrams: Draw the Forces, Find the Net Force
Students add and subtract forces to find net force, then draw and label free-body diagrams for five situations and calculate weight, tension and acceleration.
Science
From DNA to Protein: Decode the Gene
Students transcribe a DNA strand into mRNA, decode it with a codon table, and predict how a single-base change affects the protein.
Science
Gas Laws by the Numbers: Pressure, Volume and Temperature
Students apply Boyle’s, Charles’s, Gay-Lussac’s and ideal gas relationships to numerical problems and explain which direction each variable moves.
Science
Heart and Circulation: Follow the Blood and Do the Math
Students trace the path of blood through the heart and body with a word bank, calculate heart rates and cardiac output from provided data, and answer questions about vessels.
