Introduce the Engineering Design Process for problem solving as you explore electricity and magnetism in this electromagnet building exercise. Students examine magnetic field, electrical charge and the effects of increasing the current on the generation of heat as they compare core materials, core thickness and number of wraps in solenoid coils in these inquiry based investigations. Four engaging activities culminate with teams applying what they learn in a design the strongest electromagnet competition. Includes an extensive instructor’s manual with lesson plans, background information, reproducible stepwise student instructions, worksheets, complete answer keys and all materials required for investigation. Available as a single kit (S07347) for a small group or a class pack (S07348) with materials for 24 students working in six groups of four. Batteries included. Safety goggles required.

Need a way for students to explicitly learn how to engage in engineering design practices to solve problems? Have them build their own simple electric motors using wire and magnets. Extend learning from solenoid coils to motors with this hands-on project set designed for the whole class. Students explore the effects of altering the coils in the motor, wire thickness and the effects of using different sizes, shapes, strengths and types of magnets as they are guided through the engineering design process. This unit is complete with four experiments which culminate in a design competition. Great for introducing guided inquiry-based learning, systematic problem solving and engineering design practices. Kits include instructor’s manuals with lesson plans, background information, reproducible stepwise student protocols and guided worksheets. Select the kit size that fits your needs; single kit (S07349) requires 3 D-cell batteries; class-pack (S07350) requires 18 D-cell batteries. Safety goggles required. Designed for working in groups of four students.

Teach simple DC circuitry using real components and help students relate classroom projects to real world applications. This basic approach introduces the use of easy to manipulate, reusable solder-less breadboards, resistors, LEDs, jump wires and batteries, allowing hands-on experience with circuitry components for individual students. Students learn to build circuits, read circuit diagrams and investigate the effects of resistors and LEDs in real circuits. Covers series and parallel circuits, LED circuits and combined series-parallel circuits. Includes instructor’s manual with reproducible student guides including stepwise experimental protocols, simple circuit diagrams, data collection sheets, homework assignments and assessment materials. This unit is complete with five experiments, lecture information, sample data and complete answer keys. Separate assignments for middle and high school levels are provided. Both single kit (S07352) and class kit (S07353) include one digital multimeter for teacher to demonstrate how to measure voltage, current and resistance so that data may be collected for problem sets. Designed for working in groups of four students.

Students explore wavelength, frequency and amplitude while immersed in hands-on experimentation. As students build their own old-fashioned Crystal Radios, they explore the effects of design variations within the coils, building materials and antennae number and length, on maximizing tuning and signal strength. Then students upgrade their crystal radio into a transistor radio. Ideal for hands-on learners, as intuition plays a role in developing antenna design solutions, iterative testing and making modifications for improvements (iterative cycle). Great for introducing guided inquiry-based learning. Includes a complete instructor’s manual with reproducible stepwise student protocols. Available as a single kit (S07354) or a class kit (S07355) which makes six radio projects. Designed for working in groups of four students.

With this kit, students will gain comprehensive knowledge of structural engineering and how it is used to support or resist loads. The class will study different types of bridges and the STEM principles that support them. They will construct six working models including a house, a suspension bridge, a cable-stayed bridge, an arch bridge and two different truss bridges. Students are also challenged to build the largest free standing tower in the class using the given Engino® components. Finally, students are challenged to apply all they have learned to build a bridge that spans 70cm and supports a minimum distributed static load of 2kg using only 100 plastic straws and a limited amount of masking tape. Includes all building and testing materials, instructor’s manual, lesson plans, Engino hands-on activity books, building instructions and student worksheets. Class kit designed for 24 students.

Trace evidence allows students to solve the crime presented in this hands-on CSI activity. Using observation, experimentation and interpretation, students employ scientific inquiry to analyze hair, fiber, fabric, blood, fingerprints and handwriting. Both evidence and personal profiles intertwine enabling students to crack the case using deductive reasoning. Includes instructional manual, reproducible student worksheets and materials sufficient for 24 students working in six groups. Additional items required but not included: microscopes, water bath, glass test tubes with stoppers or caps.

Students are introduced to qualitative analysis in the intriguing context of criminal investigation. Chemical analytical techniques are used to identify over-the-counter drugs, to test for controlled substances using simulated drugs and to detect heavy metals and amino acids in body fluids as part of a simulated poisoning. Includes materials for six groups (24 students) and an instructor’s manual with reproducible student instructions, data sheets and complete answer keys. Required but not included: UV light, microscope, oven, lamp, or hot plate, scale, glassware and lab supplies. Kit includes Lead Nitrate and Potassium Chromate.

Minerals and Soils Analysis teaches students to utilize physical and chemical techniques to thoroughly investigate crime scene samples. Soil, glass, dust and metal traces are just some of the types of materials that are analyzed in this kit to link a suspect to the scene of the crime. Analyses include comparison of acidity; comparison of particle sizes using sieves; comparison of particle densities using density gradient tubes; and comparison of minerals present through the use of wet chemistry. Required not included: fume hood, UV light, balance, microscope, oven / lamp / or hot plate, glassware and general lab supplies. Contains lead nitrate.

Dental records, like fingerprints, offer a form of positive identification. Not only do they differ in detail from person to person, but they last longer than other physical evidence and may be the only identifiable body characteristic following catastrophic accidents, explosions, burning or decomposition. Kit includes seven experiments: Making a Patient Dental Chart, Identifying a Body with Dental Charts, Casting Teeth, Evidence Analysis of Bite Mark Injury, Collecting Evidence (Bite Marks in Wax Molds), Identifying Suspects from Bite Marks and Identifying Suspects (Matching Teeth Casts to Wax Bite Planes).

The Kemtec Master Forensics Kit allows participation in many aspects within the field of forensic science, which involves chemistry, physics and biology along with the use of reasoning and common sense. This kit is designed to introduce students to the techniques needed to accomplish a thorough criminal investigation. It contains sub-units of our Fingerprint Analysis, Soil and Mineral Analysis, Hair Analysis, Document Analysis and Analysis of Drugs and Poisons kits. After learning these techniques, students use them to solve crime scene scenarios outlined in the kit. Complete with manuals, CDs and student data sheets. Designed for 24 students working in groups of four. Contains lead nitrate.
