Herpetology FIELD TRIP!!! January 27, 2016Posted by jessicategt in Events & Announcements.
***SPECIAL NOTE: Due the to weather this week, this field trip has been rescheduled for Tuesday, February 9th!***
This Tuesday we will be visiting some herpetologists (the scientists who study reptiles and amphibians) at Mississippi State University and seeing specimens of all kinds of animals you may have never even heard of! There are several key differences between reptiles and amphibians including their skin, leg placement, and eggs. Reptiles have scales, legs underneath their bodies, and eggs with leathery shells that are laid in dry environments. Amphibians have moist, smooth skin, legs attached to the sides of their body, and shell-less eggs that have to remain damp to hatch. Some reptiles and amphibians are very secretive and not often seen while others are very common. We will hopefully be observing many different kinds of herpetofauna on our field trip!
Frog Dissections January 20, 2016Posted by jessicategt in Events & Announcements.
In the fall, we dissected fish to examine their external and internal anatomy. This week, before we learn more about reptiles and amphibians, we will be looking at the anatomy of frogs. Many of a frog’s systems function in the same way as ours do, such as the circulatory system (though frogs have a 3-chambered heart while mammals have a 4-chambered one) and digestive system. We will also see several unique features of frogs. See you on Tuesday for the dissections!
DNA Extractions January 13, 2016Posted by jessicategt in Events & Announcements.
After our discussion last week, you have learned the basic structure of DNA as well as the important role it plays in genetics, it is the code for who we are! This week we are going to extract DNA so that we can see it, without the use of high-powered microscopes. We will look at human as well as plant DNA. We will also discuss the structure of cells and how the process of separating DNA from animal and plant cells are different. See you AND your DNA on Tuesday!
Genetics January 4, 2016Posted by jessicategt in Events & Announcements.
Happy New Year and welcome back, Science Club! During our first meeting of 2016, we will begin a two-part exploration of genetics and DNA. All living things have amino acids (the building blocks of life found in DNA), from trees to jellyfish to bananas to people. We, as humans, all have so much genetically in common and yet we are completely unique at the same time. We get an equal amount of our genes from our parents, 50% mother and 50% father. This week we will talk about the chances of young getting certain traits (or characteristics) from their parents. Some are easily calculated (like eye color in people or plumage in chickens) while others are so complicated scientists are still trying to figure out how they work.
Arctic Wildlife December 13, 2015Posted by jessicategt in Events & Announcements.
Even though it’s been a warm fall and early winter, we will discuss and explore some of the most common wildlife associated with the frigid temperatures of the Arctic region. We will understand how endothermic mammals can stay warm in freezing temperatures and discover the many adaptations of cold weather creatures. This will be our last meeting of the year and we truly had a great first semester! Looking forward to 2016! Happy Holidays Science Club!!!
