Who is Your Closest Relative?

dfix — Wed, 30 Apr 2008 16:12:04 +0000

Students constructed a cladogram showing the evolutionary relationships of humans, chimpanzees, gorillas, gibbons, and orangutans based on DNA evidence. Play the slide show to hear and see how it was done. To view a bigger version of the slide show, go here.

Let’s Grub on Some Grass Beetles

dfix — Sun, 13 Apr 2008 22:21:02 +0000

Students participated in a natural selection simulation called Let’s Grub on Some Grass Beetles. Play and listen to the video on how it was done.

Genetics Simulation

Watch and listen to the slide show on the genetics simulation that was done in class.

DNA Models

dfix — Thu, 06 Mar 2008 16:56:39 +0000

Students constructed 3 dimensional paper DNA models. They learned that DNA is made up of nucleotides. Each nucleotide is comprised of a phosphate, deoxyribose sugar, and a nitrogen base, which can be cytosine (C), thymine (T), guanine (G), or adenine (A). Students then had to answer questions based on the model. Here is a slideshow of the students.

Human Traits

dfix — Thu, 06 Mar 2008 01:19:02 +0000

Students did a simulation where they were heterozygous for 17 different facial traits. The pictures show them flipping coins to determine which allele, dominant or recessive, they were going to give to the offspring. Once they got the offspring gentoypes, they then had to draw the offspring phenotypes.

Reebop Genetics

dfix — Mon, 03 Mar 2008 14:33:51 +0000

Student did a simulation of Gregor Mendel’s experiments with pea plants. Instead of using pea plants, students used fictional organisms called reebops. Watch and listen to the slide show to see what mechanism controls the inheritance of reebop traits.

Yeast Cellular Respiration

dfix — Wed, 20 Feb 2008 21:07:24 +0000

During the cell unit students learned how cells unlock energy in food. More specifically in the mitochondria oxygen reacts with glucose to release energy, carbon dioxide and water. In the video below students got to observe yeast cells doing this process. Bromothymol blue solution turns yellow when carbon dioxide is present. Watch and listen to the video for further explanation.

Biology in the News Extra Credit

dfix — Wed, 20 Feb 2008 19:57:47 +0000

This is a rare extra credit opportunity in science. Play the slideshow to learn how to do it. It’s worth up to 10 extra credit points. Last day to submit 3/14.
