Question

How many centimeters of root growth will result from putting a geranium clipping in water?

Standards

Cell Biology

7.1. All living organisms are composed of cells, from just one to many trillions, whose details usually are visible only through a microscope.

f.    Students know that as multicellular organisms develop, their cells differentiate.

Genetics

7.2. A typical cell of any organism contains genetic instructions that specify its traits. Those traits may be modified by environmental influences. As a basis for under­ standing this concept:

a.  Students know the differences between the life cycles and reproduction methods of sexual and asexual organisms.

Experimental Design

A geranium clipping is placed in water in a window sill with indirect light from October through January.  Root growth will be monitored each month and root length will be measured with a ruler.

Independent variable

Geranium branch

Dependent variables

Sed auctor facilisis lobortis. Vivamus eu diam orci. Sed blandit, mi a tincidunt commodo, purus nulla imperdiet arcu, eget rhoncus risus nibh sit amet tortor. Sed sed nibh id quam aliquam placerat vitae eget neque. Nam fermentum varius vulputate. Nullam vel erat et nulla auctor mole

Series

Pellentesque ornare feugiat nunc. Cras gravida sagittis augue non aliquam. Quisque non mi ante, vitae convallis nisi.

Controls

Vivamus suscipit placerat massa, ac ullamcorper quam congue id. Sed auctor facilisis lobortis. Vivamus eu diam orci.

Materials

Sed blandit, mi a tincidunt commodo, purus nulla imperdiet arcu, eget rhoncus risus nibh sit amet tortor. Sed sed nibh id quam aliquam placerat vitae eget neque. Nam fermentum varius vulputate. Nullam vel erat et nulla auctor molestie.

Procedures

Sample data and graphs

Nam pharetra erat vel purus vulputate convallis. Morbi ac augue nibh, vel dapibus felis. Nulla facilisi. Phasellus vehicula cursus enim et iaculis. Cras massa felis, scelerisque gravida euismod eu, condimentum vel mauris. Maecenas sit amet risus ut odio consectetur venenatis.
