Laboratory Assignment: Designing and Instructing Laboratory Experiences
One of the greatest challenges to the secondary science teacher is the creation, implementation, and evaluation of quality laboratory experiences. The purpose of this series of assignments is to get you to begin thinking about the role of laboratory work in the secondary science classroom and how its effectiveness can be optimized.

You will be designing and teaching a 35-40 minute laboratory experience to your BSC 307 peers. Details of the assignment can be found in the assignment description sheet. Please make sure to use the templates provided for your lesson plan and lab considerations document.

 * [[file:Doellman, 5E Laboratory Assignment Lesson Plan.doc]] Rollin' in the Dough** (Melissa Doellman): In this lab, students investigate the process of cellular respiration in yeast through the context of baking bread. After completing a guided lab examing the effects of sucrose concentration on yeast respiration, students graph and analyze the collected data. Students will also design and complete their own experiment to test the effects of other bread ingredients on yeast respiration. The total length of this activity is suggested for three class periods.


 * [[file:Bagby_5E Model Laboratory Teaching Model Lesson Plan.doc]] Sensory Lab-** Meghan Bagby: In this lab, students will investigate sensory receptors in the human body. This lab encompasses a guided exploration portion where students take data on different sensory systems of the human body. Then they will make conclusions based on their individual group data and the data of the class. Once that is complete students will design their own experiment for taste receptors and heat receptors in the human body. This lab should take about 3 days to complete from start to finish.

Basic Lab Considerations


 * Prendergast, Michael**. Laboratory Assignment, Bloodstain Analysis. In this lab, students will use a simple chemical test to determine the murderer of a local pizza delivery man. They will review basic concepts of enzyme reactions and proper scientific experimentation. Included below is my 5E model Lesson Plan, a basic lab consideration form, a teacher guide to the lab, a student handout, and the power point I will use as a part of my engagement.


 * Sandy, Emily.** 5 E Model Laboratory Assignment, Plastics by Numbers. In this lab, students will be given 6 unmarked plastics and must find out the resin code for each from a sheet left by the 'old supervisor' at the hypothetical plastics sorting facility. They will be graded on their problem solving skills, observation skills, and the quality of their notes and reasoning. Below is the 5 E Model Lesson plan, Teacher Guide, Lab and Handouts, and the related PowerPoint.



Here is a very simple but meaningful science inquiry activity which uses silent movies. Students can practice science inquiry thinking skills through observation of the filmed experiment. Below is the 5 E Model Lesson plan, Lab and Handouts, and the related PowerPoint.
 * Kim, YoungHak.** 5E Model Laboratory Assignment. Enjoy Silent Movies! : Using silent movies for the science inquiry classroom

**Milica Leone, Plasmolysis of Elodea Lab.** This lab has students investigating plasmolysis in Elodea leaves. The students are given a problem as their engage (ecologists in Mississippi want us to tell them what happens when saltwater begins to invade the freshwater wetlands along the Gulf Coast). Students will observe and draw Elodea under different salt solutions, draw conclusions about what they have observed and how it will effect the ecosystem, then as an expanded assignment, the students will come up with a solution to the issue. This is the 5E Model Sheet.

This is the Teachers Guide that goes along with the Plasmolysis of Elodea Lab.

This is the Basic Lab Considerations sheet for the Plasmolysis of Elodea Lab.

This is the student lab worksheet the student will use during the lab. It is 6 pages and contains step-by-step instructions for the lab as well as places to draw pictures and answer questions on the lab.

This is the expansion project for the lab. This is a very basic version of the expansion project as my plan is to go much more indepth and use this as my authentic assessment. I just wanted to provide a quick overview of what the students would be doing as their expanded project on days two and three of the lab. Wisniewski, Ammands--> What Part of a Plant Do We Eat? This lab experiment discusses the basic structure of plants. Touching into fruit and vegetable structure and discussing evolution/diversity based on artificial and natural selection. Basic lab Considerations for What Part of a Plant Do We Eat? Student lab handout sheet Teachers guide to Lab: What Part of a Plant Do We Eat? This is the expansion project where the students conduct a mini-research write-up furthering their investigation of artificial selection of fruits and vegetables.

Maggie Quinn's 5 E lesson for the laboratory. In this lab student's learn of human impact on the enviroment. Through cleaning up a simulated oil spill, students will learn how ecosystems and populations are intertwined.

Carrie Simonson's 5 E lesson for the laboratory. Students will be investigating the properties of water.

Chelsey O'Connor's "Who Stole the Macaw at Petland" lab- In this lab, students will be asked to help the Bloomington police in analyzing DNA samples found in a burglary at Petland. The students will analyze the DNA by constructing their own gel electrophoresis!

Flanagan: This lesson is an introduction to homeostasis and feedback mechanisms, especially when it applies to Thermoregulation. Included below are the student worksheet, the lesson plan and teachers guide, introductory email and case studies and a post lab Power Point



Abbott, John: Pom-pom Predators - Experiment in which students explore the concept of natural selection and evolution.

 * Benjamin, Jamie. Acid-Base Lab-** This lab allows students to become more familiar with acids and bases. Within this lab students will test the pH of common household items thus allowing them to make the connection with their homes. This lab also connects these household items to their bodies and other living and non-living things. This lab follows the 5-E Model and includes the following the lab for students, teachers guide, lab considerations, lesson plan and labels for the stations.


 * Dawson, Amanda. Blood Typing-** In this lab, the students are asked to investigate the crime of stolen computers in the high school. Using milk as simulated blood, the students will test the reactions between the blood and antibodies (water and vinegar). The students will then test the blood left at the crime scene and from a suspect, to determine if the suspect is guilty. The concepts of antigens, antibodies, and blood types are discussed.



**Patrick Murphy - Density** In this lab the students will have to find the density of certain materials for a plane crash victim. Once they have done this they will build a raft of a material they select to save the survivor. The concept of density and the skills of measurement will be used throughout this laboratory.


 * Amanda Monaco - Nightmare on Bug Street Lab**. In this lab students will take on the role of casting directors for a play in which mealworms will be the actors. In the first part of the lab they will make observations of their natural behavior and their responses to various stimuli. Then they will follow the steps of the scientific method to design an audition for the mealworms.


 * Megan Sharp- Jell-O and Enzyme Lab-** In this lab students will have to figure out why fresh pineapple will not solidify in Jell-O. In this lab students will further be exploring the basic functions and properties of enzymes. Students will be working with three different types of pineapple; fresh, canned, and frozen. Student's will then analyze their results and try to figure out why canned pineapple works and fresh pineapple doesn't allow the Jell-O to solidify. Students will then research important roles enzymes play in everyday life, and other important functions of bromelain.
