Density Slice : How to calculate the area of objects using Density Slicing (A technique used to highlight a range of pixel values)
Set image scales Using the rectangle selection tool Use density slicing techniques to calculate area Tree Ring Geometry: The Chaco Canyon Story
Interpret tree ring data Setting scale Calculate radius, circumference and areas of circles. Measuring length Organize, graph and interpret data Compare measurements and calculations
General Science
Butterfly : A measuring exercise + a little background on butterflies
Learn a little bit about butterflies. Move between stacked images Comparison with other insects - including moths.
Fibers: Calculating the porosity of different fabrics
Set image scales Measure length and area
It's Just a Phase: Observing the Moon's Cycles
Recognize lunar phases Setting scale Graph and interpret data Measuring length, area and calculate percent Density Slicing
Aral Sea : Environmental changes in the Aral Sea
Examine ecological/human consequences of Aral Sea catastrophe Measure distances Measure surface area changes in the last three decades Calculate surface area (Density Slicing) Biology
Cells : A comparison between plant and animal cells.
Compare the onion plant cell with the human cheek cell Copy and paste between images Compare the sizes of the two different cells Set image scales Identify the various cellular structures and their relative sizes Measure length, width Learn to distinguish between plant and animal cells Measure area
Elodea:The effect of osmosis and plasmolysis on the plant cell Elodea
Identify typical plant structures Copy and paste between images Compare the elodea plant cell before and after the process of plasmolysis Set image scales Identify plant cellular structures both before and after plasmolysis Measure length and width Calculate the size of the plant's vacuole based on this experiment Measure area
Bone Density : This exercise examines normal and osteoporotic bone.
Examine the problem of osteoporosis. Open up X-ray images Compare skeletal X-rays of normal and osteoporotic patients. Use density slicing to determine bone density. Identify the different lumbar vertebrae Graph bone density results
