Document Summary

Principles that are involved in designing classroom language test and how they are to be applied. There are 6 crucial questions that must be asked when designing and administering a test. How it will impact you and your students. What are you trying to find out. What language abilities you will be testing. The test structure must follow from the lesson it is testing. Task types and weights should be appropriate, logically sequenced, and of suitable variety. They should mirror tasks of the course. They should be biased for best performance. It must be possible to evaluate them reliably. Students need to feel well prepared for their performance. Conditions for taking the test must be adequately established. The test should reduce student anxiety, raise student confidence, and be seen as an opportunity to learn. The type of feedback given to students depends on the purpose of the test. 4 assessment scenarios for which the 6 questions may be asked.

For the first part, you will write three different effective learning objectives focusing on insects that will support the standard from your discussion. For the second part, you will search for an existing insect-based lesson plan on the internet. Identify the standards addressed in that lesson and re-write your own learning objectives for the lesson plan.

Things to remember about learning objectives:

Learning objectives are brief descriptions of specific things a learner completing the lesson will know or be able to do. They should be succinctly expressed using clear action verbs.

The text of effective instructional objectives includes three parts. These parts are best described in the work of training and human performance expert Robert Mager:

description of a performance - Question to ask when writing this part: What do I want students to be able to do? The performance must be observable so be specific (E.g., Don't simply state students will understand something. You can't observe that. Students will define in writing, sort insects into groups by order, etc.).

conditions - important conditions under which the performance is expected to occur Examples: Given a list of... (sort into stacks); when provided with standard tools... (construct a table); without using references... (know the state capitols) Questions to ask when writing this part: What are the important conditions or constraints under which I want them to perform? What the learner will be provided? What will the learner be denied? Are there special conditions which occur on the job or when performing?

criterion or standard - the quality or level of performance that will be considered acceptable. Examples: include measures of speed (in less than 30 minutes...), direction (according to manufacturers specifications...), accuracy (without error...) , quality (all cuts must be smooth to the touch). Question to ask when writing this part: How well must learners perform for me to be satisfied they've accomplished the objective?

Part 1 must include:

1.The grade level, the Big Idea/Supportive Idea, and Next Generation Sunshine State Standard (5 points).
2. Three effective learning objectives (see advice above) that focus on insects and support that standard (5 points a piece).

Part 2 includes:

1.A working link for the lesson plan (2 points).
2. The grade level, the Big Idea/Supportive Idea, and Next Generation Sunshine State Standard (3 points).
3. Three effective learning objectives that focus on insects and support that standard (5 points a piece).

can anyone help with this really super basic lab? Feel free tomake up data, highschool level information please!

You are NOT limited to the suggested projects listed below.Think up your own unique research project!!

Projects should involve observation/measurement of livingorganisms-plants, animals, fungi, humans. They should be designedto answer a question or to test a hypothesis. Examples ofhypotheses would be; "Plants will grow more if there is morerainfall" Or "Students will get higher grades if they study more."Sample size is important when possible; make multiple measurementsof several individuals. Your project must be something thatproduces DATA that can eventually be graphed. There should be adependent variable and an independent variable. For example,"amount of rainfall" would be an independent variable and "how fastplants grow" the dependent variable.

Projects should take approximately three hours, total, tocomplete, not counting the write up, which will be a separate lab.Detailed instructions on writing your report are attached. Keepyour project simple and manageable. Submit your first project bythe due date for Project 12 (July 7th)**Please make sure that yourassignment gets to me by the due date. You will still be able toupload your assignment after the due date, but it will be marked aslate, and you will lose some points for being late.

A few examples of projects:

Is there a correlation between the size of a dog, and how longit lives? For this you will need about ten dead dogs! Ask aroundamong friends, classmates, family, about dogs that died a naturaldeath. Find out each dog's age at death, and approximate weight. Alarger sample size here would be even better. Can you explain thecorrelation?

Do humans have a physiological response (difference in pulse,blood pressure, etc.) to music? Choose three different categoriesof music, such as classical, folk, rock, or none (silence). Have atleast five people in your study, and measure their pulse (or bloodpressure) both before and after they have listened to the music for5-10 minutes. Graph the increase (or decrease) in their pulse forthe different types of music. GRAPH THE AVERAGE values for yoursubjects, not value for each individual.

Is there a correlation between a person's usual amount of sleep,and how well they perform on memory tasks? Devise a SIMPLE memorytest-it could be just to study a list of twenty random words, andthen to recall as many as possible. Give this test to at least fourpeople who usually get (a) less than 6 hours sleep, (b) 6-7 hourssleep and (c) 8 or more hours. Or, choose your own categories.Amount of sleep is your independent variable (X axis) and AVERAGEscores on the test, the dependent variable. (Y axis). GRAPH THEAVERAGE!

Include ALL relevant observations and information in precisedetail. If possible, include illustrations of your experiment, yoursubjects, your work in progress, etc.

BIOTECHNOLOGY

Introduction

In this Experiment we will learn how to identify the unknownbacterium according to the case study given as you start to performyour procedures and following the steps. Also, we will be learningthe outcome of a specific case scenario of immunity. We will beperforming different examples of media and observing the reactionafter inoculation and adding different reagents as it produce somechanging of color diagnose to a negative or positive results. Also,we will conduct different types of biochemical testing includingIndole production, Citrate Utilization, Methyl red test, andMannitol Fermentation.

In this case scenario we are trying to figure out theinfestation of food at the warehouse causing a death of theplaintiff mother. The plaintiff is accusing the warehouse forselling these infested products by insects. At the warehouseinspection is been done by swabbing and acquiring the type oforganism to be identified as evidence for the court finaldecision.

One of the major findings in this experiment is that itwas negative gram stains and the Indole and Methyl Red Test had apositive reaction. Additional testing was perform which show theresult of only negative on Lactose Fermentation and the remainingthree additional testing add up to a positive. The outcome of thisinvestigation scenario could be a negative result to the casescenario presented about infested products by insects since nounknown bacteria was left to bediagnosed.

Procedure

The following steps are requiring completing this labexperimental. First make sure you open the Virtual UnknownSoftware. Complete conducting using Indole production and CitrateUtilization, Methyl Red test choosing from your media option. Alsomake sure you open the reference book for each procedure to beinformed of the lab steps and decision making such as positive ornegative and its color after inoculation.

Observations and Results

	Result + or -	Appearance after Incubation
Gram Stain	- gram rods	N/A
Indole Production	+ positive	Yellowish-after incubation & adding Kovacâs reagent changingto a cherry red color indication of positive
Mannitol Fermentation	- neg	Red
Methyl Red Test	+ pos	Turbid yellowish after incubation and adding methyl red reagentchange to red positive. +
Citrate Utilization	- neg	Greenish after incubation. No reagent added.

Additional tests performed are listed below:

	Result + or -	Appearance after Incubation
Lactose Fermentation	- neg	Red- no reagent added
Sucrose Fermentation	+ pos	Yellowish- no reagent added
Phenol Red Rhamnose (Lactose Steps)	+ pos	Yellow- no reagent
Phenol Red Xylose (Sucrose Steps)	+ pos	Yellow- no reagent

Bacterium identified as: You may want to do some additionaltests to conclusively identify your bacterium. Some good ones to domight be lactose and sucrose fermentation, like you did last week.Remember, they use Phenol Red Lactose Broth and Phenol RedSucrose Broth and yellow= positiveand red =negative. After you do those two tests,you may want to do Phenol Red Rhamnose and Phenol RedXylose, which are set up the same way as the sucrose andlactose tests, they just have different sugars. Be sure to recordyour test results!

Discussion

Identify the bacterium â Make sure you look in the VirtualUnknown lab report to make sure you got the right organism. Afteryou have made your identification, look at the lab report. You cando this by going to the View menu in Virtual Unknown and selectingLab Report. You can double check with me that you are researchingthe right one.

Once all observation was performed including the additionaltesting I was left without an Unknown organism to be identified.This only leave me with a diagnose to state that no evidence wascollected to accused the warehouse as being infested with insectsaccording to the case study.

Explain what features of this organism make it an idealcandidate host for your insecticide. (Hint: remember you will needto infect insects with the bacteria to deliver the insecticide.)âFind out where the unknown organism was isolated from.

Describe in detail the steps you will take to insert the targetgene into the bacterium. - Figure 8.1 of your book should help youwith this.
