Population Dynamics of Growth of Drosophila
Learners experiment with Drosophila to determine if density of female flies, food sources, temperature and light affect the population dynamics of growth. Students graph their data and compare their results to the number of human...
Curated OER
Signal Transmission in the Nervous System
Learners explore signal transmission in the nervous system. They determine the speed of nervous transmission in an integrated nervous system and investigate the differences between signal transmission in a single neuron and in a nervous...
Curated OER
What Does Your "Homunculus" Look Like?
Students determine the density of touch receptors in various parts of the body on the right hand side. They use collected data to draw a picture of the
"homunculus" of an experimental subject.
Curated OER
ISOLATION OF DNA FROM ONION
Students perform a lab in which they extract DNA from onion cells. Students break through the cell and nuclear membranes and then break down the protein that the DNA is wrapped around.
Curated OER
SEPARATION OF A STARCH-GLUCOSE MIXTURE USING GEL FILTRATION
Students make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...
Curated OER
CULTURING PLANTS FROM EMBRYONIC PLANT TISSUE
Pupils use this laboratory exercise as a growth medium that contains the macronutrient and micronutrient needs of plants. They observe the effects of different hormones on tissue cultures and must use variations of the basic growth medium.
Curated OER
Comparison of Four-, Six-, And Eight-bp Cuts in Calf Thymus Dna
Students investigate the use of restriction enzymes to recognize a four-, six-, and eight-nucleotide sequence. They utilize restrictive endonucleases to cut Thymus DNA and compare results by viewing the DNA fragments on Agarose Gel...
Curated OER
Active Ingredient Screening Test for Plants
Students explore the growth of bacteria. They determine if various plant materials contain active ingredients that inhibit the growth of bacteria. In addition, they complete a student data sheet.
Curated OER
Collect Your Own Drosophila Lab
Learners study Drosophila by catching them. They construct catcher-containers to catch Drosophila using fruit as bait. After collection, they examine the flies and collect data to be displayed.
Curated OER
Observing the Development of Drosophila in Apple Juice Agar
Students observe the development of the Drosophila fly. They observe the first two stages - the egg and the 3 larval instars. They observe the culture every day for 8 days using a stereo dissecting microscope.
Curated OER
The Effect of Citrus Oils on Fruit Flies
Students answer the question, "How could citrus fruits be toxic to fruit flies when fruit flies live on fruit?" They conduct an investigation using four different citrus oils and fruit flies and analyze data collected.
Curated OER
A Lab Trilogy for Beginning Biology Teachers
Students are able to explain their models to other students and to their parents. Then students like to decorate the room by hanging the models or constructing mobiles of a number of models.
Curated OER
Extraction of DNA from Onion
Young scholars study DNA by isolating it from plant tissue. They determine the purpose of each step in the isolation procedure as it relates to the physical and biochemical characteristics of the genetic material
Curated OER
Plant Biotechnology: Controlling Tissue Differentiation
Young scholars demonstrate hormonal control of plant tissue differentiation and relate this differentiation to gene expression. They explore the effects of hormones (auxin and cytokinin) on the genes that control tissue differentiation...
