This fun, interactive, project-oriented forensic science course is designed to engage students Grades 4-5 in this truly fascinating area of science! Your students will become immersed in roles as crime scene investigators as they work together examining and analyzing evidence needed to solve the mystery of the broken cookie jar!
A crime has occurred in Mrs. Randall classroom! Her favorite cookie jar was broken and some of her homemade cookies were eaten. While breaking a cookie jar and snitching a few cookies are hardly serious crimes, they are nevertheless crimes that can be solved using a forensic science approach.
Mrs. Randall turns this misfortune into opportunity and calls in a “Chief Crime Scene Investigator" (your teacher) to lead her “forensics team" (your students) in how to use the tools of forensic science in analyzing clues left at the crime scene. Each student member of this investigative team is tasked with solving the mystery through scientific observation, sample examination, analysis, lab work, testing, interviews, and field work.How it Works
To draw the students into the mystery, the instructor sets the stage by recounting Mrs. Randall intriguing tale. In advance, the instructor creates names for the four student suspects names that students will find believable. These names replace “Suspects 1 - 4" used throughout the course materials.Preparing to Teach
Instructors will find The Cookie Jar Mystery easy and fun to teach. Each lesson provides 1-3 activities that teaches a new but related aspect of scientific reasoning and a particular scientific process. The text is easy to read and understand, the set-ups are detailed and uncomplicated, and the processes and procedures are clearly explained in each lesson plan.
The Summer Camp version of the Cookie Jar Mystery contains an Instructor Guide, Resource CD. Printed packet of all student handouts, and every supply item necessary to teach a class of up to 30 students. This includes unique items like simulated blood and chromotography paper to scissors and pencils.‚
Instructor Guide:‚ Every step is taken to provide an easy-to-follow format and informative, fun-to-read instructions for each lesson. In addition to a brief listing of objectives, materials, and set-up procedures, useful icons point the instructor to a number of key elements:
Resource CD: The Teacher Resource CD for the Cookie Jar Mystery includes all the copy masters for student handouts, activities, lesson extensions like crossword puzzles to reinforce newly learned used vocabulary and learning aides. Links to forensic videos and other multimedia resources provide authentic lesson extensions in addition to teacher tutorials for each hands-on activity.
Lesson 1 - Heads Up-Observation Skills
You can't believe your eyes or can you? Budding CSI investigators love to explore the challenge of visual memory and eyewitness testimony in this activity of "Did You See That?"
Lesson 2 - Think Ink-Ink Chromatography
The telltale composition of ink can help CSIs identify the perpetrator when students make their own ink chromatographs. Easy-to-follow instructions lead the way in your classroom's forensics laboratory.
Lesson 3 - The White Stuff-White Substance and Toxicology
Take a powder, please! Students get a closer look at the differences in white substances (Of course they're all non-toxic!) and at the world of poison science in this riveting research.
Lesson 4 - Pull Some Strings-Fiber Analysis
Can scientific analysis of fibers help identify our thief? Students use pocket hand lenses to get up close and personal with fiber analysis, and learn to distinguish between class evidence and direct (conclusive) evidence.
Lesson 5 - Hair We Go-Hair Sample
Who knew hair could be so complex? In this activity, can our junior gumshoes match a hair sample to the correct suspect? This absorbing inquiry will have students scratching their heads (and plucking their own hair!) as they delve deeper into the Cookie Jar Mystery.
Lesson 6 - Follow the Grain-Pollen Analysis
Achoo! Pollen as evidence? Learners explore another form of trace evidence that often tells where something happened. Students do the legwork in the field as they practice with this essential tool.
Lesson 7 - Make an Impression-Bite Marks
Surprisingly simple materials provide all you need for another great lesson in comparing and contrasting for students to "sink their teeth into."
Lesson 8 - Bloody Brilliant-Blood Types
Of course, it's not real blood - but we do provide blood evidence substitute that encourages learners to handle evidence just like genuine CSI laboratory technicians. This lesson in blood typing provides a great jump start for future scientists, geneticists and crime scene detectives.
Lesson 9 - One of a Kind-Fingerprint Evidence
Oh, the things we leave behind! Everything you always wanted to know about whorls and ridges, fingerprinting technique and more with authentic Ten Cards for each student to make a record of his/her prints.
Lesson 10 - Crack the Code-DNA
Learning to unravel the mystery of our genetic code is revealed in this straightforward explanation and lesson helps learners narrow the field of suspects.
Lesson 11 - Let's Talk-Questioning Our Suspects
A lie detector isn't the only way of getting at the truth! In this lesson, our junior CSI detectives learn the meaning of the "norm" and how knowing the norm helps sort truth tellers from liars. Students also return to the "scene of the crime" for another look.
Lesson 12 - Who Dunnit?-Examining & Analyzing All the Evidence
Means, motive and opportunity all come together in this culminating activity that encourages students to put all of the puzzle pieces together and finally solve the Cookie Jar Mystery!
