Exploring Air Resistance Investigate the relationship between velocity and air resistance. View »
Ideal Atwood Machine Use this classic physics problem to analyze the forces acting on a set of weights suspended over a pulley. Calculate the acceleration of the system by applying knowledge of Newton's second law of motion, free-body diagrams, and kinematics. View »
Derivation of the Kinematics Equation A solid understanding of kinematics equations and how to employ them to solve problems is essential for success in physics. Take a quick look the algebraic derivations behind these equations. View »
Lumbriculus: Contraction Rate of the Dorsal Blood Vessel In this introductory physiology lab, students determine the contraction rate of the dorsal blood vessel of the blackworm Lumbriculus. Students then design and conduct an experiment to determine the effect of temperature change or chemical exposure on the contraction rate. View »
Daphnia Heart Rate In this introductory physiology lab, students determine the heart rate of Daphnia magna and then test the effect of changing temperature on the heart rate. View »
Stoichiometry and Limiting Reactant Develop a model for a limiting reactant in a chemical reaction, analyze combining ratios for reactions, and write balanced equations for them. Activity supports NGSS instruction. View »
Volcano in the Classroom Here’s a safe, easy, and vivid interpretation of a classic activity that won’t break the budget. All you’ll need are a few common items—a beaker, sand, water, a candle, and a hot plate. View »
Under The Dome: Demonstrations with a Vacuum Pump Get out your vacuum pump for engaging activities and demonstrations designed to enrich your lessons on the properties of gases. View »
Invasion! Invasion! Engage life science students by investigating a fascinating topic: invasive species. Here’s a lesson plan outline to help you get started. Based on the KWL chart, it guides you through 4 days of invasive species activities that introduce the topic, guide research, and culminate in a research project. View »
Ballistics: Student Investigation Sheet How do holes left by projectiles help forensic investigators? This activity asks students to calculate the angle of incidence of several perforations. View »
Bloodstain Analysis: Student Investigation Sheet Like other physical evidence, blood often links a scene, perpetrator, and victim. This activity describes how to determine the angle of incidence of a blood drop. View »
Five Photography Terms Every Arson and Crime Scene Photographer Should Know Despite its advantages, photography remains the least understood and developed skill for arson and crime scene investigators. Learn about key terms and techniques and try a fingerprint distortion activity. View »
