BIOTECHNOLOGY VIRTUAL LABTERMINOLOGY – CORNELL NOTES

BIOTECHNOLOGY VIRTUAL LABTopic: Name

Biotech Virtual Lab Class

Terminology PeriodDate

ECB -European Corn Borer

Yield -Amount of crop production

Infestation -Overrun with pests and parasites

Independent Variable

-Types of Corn & their level of infestation: BT123, Super Harvest –NonBT; BT456; Golden Crop – NonBT Crop

BT Corn - BioTransgenic Corn

Growing Conditions for

Corn

Controlled Soil, moisture, temp,

l ight & nutrit ion

Dependent Variable -Yield of corn plant in terms of kernel mass (g)

-Soil, nutrients, watering amounts, light, heat, infestation level

Dependent vs. Independent VariablesScientist use an experiment to search for cause

and effect relationships in nature. In other words, they design an experiment so that changes to one item cause something else to change in a predictable way.

These changing qualit ies are called variables. A variable is any factor, trait or condition that can exist in differing amounts or types. An experiment usually has three kinds of variables: independent, dependent and controlled.

The scientist focuses their observations on the dependent variables to see how it responds to the change made to the independent variable . The change of the dependent variable is caused by and depends on the value of the independent variable.

Dependent vs. Independent VariablesExperiments also have controlled variables.

Controlled variables are factors that a scientist want to remain constant (the same), and they must observe them as carefully as the dependent variables. Controlled variable are used to compare the dependent variable’s changes in experiment’s relationship and keep the tests fair .

Underl ine the independent variable and

circle the dependent variable in each.

Dependent vs. Independent Variables

1.The price of gas determines how much I wil l purchase.

2. If I do not want to gain weight, the amount of exercise I need to do is a result of how much I eat.

HypothesisBased on what you know about the

experiment…..

In your Cornell Notes:If we test four different types

of corn under similar conditions and change only the infestation level, then we should be able to determine and give evidence for which corn type wil l provide the highest yield and withstand ECB attack.

• There are 8 different data collection tests.• Continue until all Data is Collected.

TODAY’S TASK LIST1) Work with a partner from your table OR

individually.2) Pick up your Assigned Computer.3)You will be held responsible for its well-

being.4) Ask Clarifying Questions as needed.5)Begin experiments & collection of data6) Our Goal is complete 8 tests by the end

of Friday’s class.

HOMEWORK1)We will be working in class on the Virtual Lab tomorrow and next week.

2)You will have homework over the weekend if you do not finish collecting data on 8 experiments.

3)This lab is not due until Wednesday of next week.
