This forensics activity allows students to practice making and analyzing bite mark impressions using styrofoam plates and a variety of soft candy. Additional instructions can be accessed at http://sciencespot.net/Media/FrnsScience/bitemarks.ppt.
This presentation gives basic information about blood and how it can be used as evidence in a crime. An accompanying student worksheet can be accessed at http://sciencespot.net/Media/FrnsScience/bloodbasicswkst.pdf. The worksheet contains a link to an online blood typing game.
This forensics presentation gives an overview of bloodstain pattern analysis and includes instructions for four blood spatter labs . An accompanying student worksheet can be accessed at http://sciencespot.net/Media/FrnsScience/bloodspatter09wkst.pdf. An angle guide needed for the fourth lab can be accessed at http://sciencespot.net/Media/FrnsScience/bloodspatter_angleguide.pdf.
In this activity, students will wear "tags" to identify themselves as common ions and find a classmate that they can "bond" with. Students will record information in a table, including the formula and the name of the compound that is created during the bonding.
In this activity, students determine the number of valence electrons for a variety of elements. They will then create Lewis structures (using pieces of cereal or small candies as electrons) to show what happens when two of the elements combine via ionic bonding.
This forensics presentation is an overview of how DNA is used to solve crimes. An accompanying student worksheet can be accessed at http://sciencespot.net/Media/FrnsScience/DNABasicswkst.pdf.
This presentation is an overview of how to identify the different fingerprint patterns. An accompanying student worksheet can be accessed at (http://sciencespot.net/Media/FrnsScience/fingerprintbasics_student.pdf). Students can then use their investigative skills to match fingerprint samples in a fingerprint challenge that can be accessed at (http://sciencespot.net/Media/FrnsScience/fingerprintchall.pdf).
Students use pennies to determine the traits for a smiley face, then use Microsoft Word to create the smiley face. Faces are displayed in the classroom and students use their knowledge of genetics to answer questions about smiley faces, traits, and probability. NOTE: Teacher notes and a "Wrapping It Up" analysis activity are separate complementary resources.
This resource is a set of directions to help students learn how to use the drawing tools in Microsoft Word. It accompanies the activity "Genetics with a Smile".
This resource is a set of teacher notes to accompany the activity "Genetics with a Smile". It includes directions and tips for teachers as well as a sample smiley face.
This student worksheet, with answer key, is used to wrap up the activity "Genetics with a Smile".
This forensics presentation is an overview of the use of hairs and fibers as evidence. An accompanying student worksheet can be accessed at http://sciencespot.net/Media/FrnsScience/hairfibernotewkst.pdf. A related hair evidence lab activity can be accessed at: http://sciencespot.net/Media/FrnsScience/hairlabwkst.pdf
This presentation is an overview of impression evidence in forensic science, including tire tracks, tool marks, shoe prints, and bite marks. An accompanying student worksheet can be accessed at http://sciencespot.net:/Media/FrnsScience/impsevidnotes09.pdf
To complete this worksheet, students visit a series of web sites where they explore the history of the microscope and identify objects viewed at different magnifications.
This presentation is an overview of the various types of physical evidence that can be found at a crime scene and how they are used to help investigators. An accompanying student worksheet can be accessed at http://sciencespot.net/Media/FrnsScience/physevidwkst.pdf.
In this activity, students will assume the functions of various cell organelles and RNA to simulate cell processes and protein synthesis. They will compete against other classes to determine which "cell" has the lowest time for creating six proteins.
This resource accompanies the activity "Protein Power Game". Students cut apart small cards to use to complete the chart that outlines the functions of each organelle as well as memory clues that can be used to help them remember the functions. It is not required for the game, but it serves as a useful pre-game review of the functions of cell organelles.
This resource contains the masters to use for the organelle necklaces for the activity "Protein Power Game".
This Power Point presentation accompanies the activity "Protein Power Game" and is used to introduce the game and to review the functions of cell organelles and the process of protein synthesis.
This resource shows the protein models students need to make during the activity "Protein Power Game".
This worksheet accompanies the activity "Protein Power Game" and includes background information and review questions.
