Applied Science - Science and Math Lab
Students examine fabric. For this Applied Science lesson, students look at the fibers of fabric through a microscope. Students compare and contrast a variety of fibers.
Curated OER
Fiber Identification
Lab sheets for three different crime scene investigation activities are tucked into this resource. In the first activity, inquisitors examine a variety of fibers, including the fiber found at "the crime scene," under ultraviolet light....

Lesson One: Lifting Latent Fingerprints
Crime scene investigators practice collecting fingerprints off of surfaces in order to compare them to an imaginary crime suspect's prints. Instructions for using graphite powder and a Zephyr brush to collect the evidence are outlined....
Curated OER
Audio Engineers: Sound Weavers
Students explore audio engineering. In this career education and "sound" science lesson, students define related vocabulary and make connections between the music they listen to and the job an audio engineer does after listening to...
Curated OER
DNA Fingerprints
Students interpret different DNA fingerprints, then do a jigsaw activity to explore other uses of DNA forensics. They listen to a radio program about using DNA as evidence and discuss the limitations of and problems with DNA testing.
Curated OER
Biotechnology: Drug Delivery and Diffusion
Young scholars discover advances in biomedical technology such as transdermal delivery and other non-invasive procedures. In lab activities, they examine how medication is given and how molecules travel, observe electrophoresis, and...
Curated OER
DNA Fingerprinting
Students study the process of DNA Fingerprinting and how DNA Fingerprinting is used in solving crimes. They examine a crime scenario that involves collecting DNA Fingerprinting information from blood collected at the crime scene. They...
Curated OER
Toolmarks Lesson Plan
Young scholars examine the scientific method and lab procedures. They solve problems using experimentation, observation, and the scientific method.
Curated OER
DNA
Learners explore the basics of DNA and its history. In this DNA lesson students extract DNA from fruits and understand how it is used in forensics.
Curated OER
Using Plant Pigments to Link a Suspect to a Crime
Students use chromatography to separate plant pigments collected from a fictitious crime scene and suspects. They compare the Rf values of the plant pigments to determine whether the plant pigments found on any of the suspects match the...
Carolina Biological Supply
Aquarium Equilibrium Demonstration
Sometimes equilibrium is a difficult concept for a beginning chemist to grasp. Here is a demonstration that helps them to visualize what is happening at a molecular level. Using two aquariums and different sizes of beakers to transfer...
Curated OER
Bloodstain Pattern Simulations: A Physical Analysis
Students receive bloodstain pattern evidence from a crime scene. They answer a series of questions through inquiry, observation, measurement, and analysis. Pupils complete this challenge, by reconstructing the evidence through four...
Curated OER
Fingerprinting
Students list and describe the three types of fingerprint patterns. They list and describe three layers of fingerprints that can be made. They explain why we leave fingerprints.
Curated OER
Who's Who and How Do You Know for Sure?
Students investigate the applications of DNA fingerprinting, They read crime scenarios and using the details of the crime and laboratory experimentation decide the suspects guilt or innocence.
Curated OER
Density of Glass Fragments
Young scholars explore how the density of an object is determined and determine what a "physical property" is. They demonstrate how science can be applied to police work.
Curated OER
Ink Analysis and Thin Layer Chromatography
Learners explain the process of TLC. They identify at least three components of ink. They analyze data and make conclusions based on laboratory observations.
Curated OER
Module 1, Unit 2, Lesson Plan 2: PCR and DNA Diagnosis
Students discuss the importance of the Polymerase Chain Reaction for biologists. They explain what factors make the Polymerase Chain Reaction possible. Students explain the steps in thermocycling and what happens during each step.
Curated OER
Biology: Howler Monkeys Tell All
Students examine a PBS special about howler monkeys as an introduction to scientific forensic investigative methods. In groups, they conduct a host of experiments containing clues which point to discovery. By challenging assumptions,...
Curated OER
What Does That DNA Molecule Really Look Like???
Students extract DNA from animal liver cells. They separate, collect and describe the appearance from the extracted DNA while role playing as an intern in a city's forensics.
Curated OER
The Ladder of Life
Students explain the concepts of what DNA is and where it is located in a cell, identify the two types of molecules that make up the rungs of a DNA molecule and identify the two types of Purine and Pyrimidine molecules
Curated OER
Soil Analysis Lesson Plan
Learners practice calculating density and examine examples of the physical characteristics of soil. They solve a "crime" based on the evidence and laboratory investigations.
Curated OER
Crime Scene Investigation (CSI) with Powdery Mildew Fungi
Students explore a specific method of identifying fungi, using a written key and an illustrated key. Powdery mildew fungi can be identified to genus by the morphology (appearance) of the sexual stage (cleistothecia).
Curated OER
Potato Launcher Energy Lab
Pupils investigate conservation laws using a potato launcher. In this physics lesson plan, students measure angles, time and distance of the potato. They discuss applications of experiments like this.
