Ecology lab experiments high school

To reflect the layers of the Earth and aquifers under the soil, this activity uses soda, ice cream, sprinkles, colored sugars, and food coloring. Students are told to use a straw to “drill a well” and “pump the well” by sucking on the straw while watching the water level drop… Continue reading “Edible Earth Parfaits- Groundwater Base” for more information.
The sections of a microscope will be described by the students. Students will be observing, manipulating, writing, and memorizing information. The cumulative magnification of the objective lenses would also be determined by the students. Using the attached handouts for different observation stations, the lab can be adjusted to accommodate higher grade levels. Obtaining Downloads Red Onion Cell Station Pollen Station… Continue reading the article “Microscopy and Cell Biology” for more information.
Via the use of preliminary activities modeled by the instructor, students will be exposed to the idea of a dichotomous key in this lab. They’ll then study the ecology and biology of a variety of marine mollusks before putting their dichotomous main reading abilities to the test on 8 or more of them. Continue reading “Mollusk Dichotomous Key” for more detail.

My students visit five lab stations to learn more about the world of microscopes after learning about the basic parts of a microscope and an overview of correct procedures for using them. I give each station at least 15-20 minutes and all of the materials required to complete the activities. For a rundown of the station activities as well as a list of resources students may need, see the Teacher Notes below. There are also unit goals and extension ideas included.
NOTE: I created this lab in response to growing class sizes and a scarcity of microscopes. It was difficult for me to teach microscope topics to 25+ students at a time with just 10 microscopes each year. I can set up groups of 5-6 students with the stations, and the students enjoy not having to share microscopes. With the exception of a few visits to keep everyone on track, I prefer to concentrate my attention on the groups at stations 3 and 4, as the others can be done with little assistance from the instructor.

Cells aren’t just the cornerstone of life; they’re also the foundation of biology education. From the concept and role of the cell to the future of biology study with pluripotent cells, this Digital Teaching Box contains tools for teaching introductory cell biology.
What are cells, what do they do, and how do scientists research something so small that they can’t see it? This unit introduces students to the fundamentals of cells and stresses the use of a microscope to get them up close and personal with the cells that surround (and within) them.

Biology lab activity

It can be expensive to order class sets of prepared slides. Want to make your own in a fun and inexpensive way? Slides, transparent tape, and animal hair samples are what you’ll need. Place a few hair strands on a slide and cover it with clear tape. A few pointers:
When looking at hair under a microscope, you’ll notice that different species have different medulla patterns in the middle. I gave my students a few samples to look at, including human, dog, and cat fur, and then a “unknown” slide to find out what sort of hair they were looking at. Ask students who have fun pets at home (such as a bunny, ferret, or guinea pig) to carry in some hairs as well.
Another option is to contact your local game and fish department for some odd hair samples. In Arizona, the Game and Fish Department provides free skull and pelt boxes to students. For my ecology unit, I borrowed the skull box and had my students compare the skulls of various species. I also plucked a hair or two from the pelts and prepared slides while I had the crate. It was interesting to see fur from mountain lions, bears, and coyotes in addition to the usual pets.
