FREEBIE! Catalase - An Enzyme Common to Both Plants and Animals Great Lab Activity! Concepts covered: 1. Enzymes speed up the rate of biological chemical reactions. Cell Models For life all cells have basic needs. Cells have diverged in their structure and function to accommodate these survival requirements. Here are some KEY TERMS to help you think, explore and search for similarities and significant differences that have become the characteristics of eukaryote (animal, plant) and prokaryotic (bacteria) cells. Examples might be searching: eukaryote prokaryote reproduction or animal plant cell energy.

First Complete Mapping Of Human Proteome Discovers 193 New Proteins In separate papers published this week, two independent teams have drafted the first maps of the human proteome -- which charts all of the proteins that make up a person. And both teams discovered that proteins do come from “noncoding” DNA sequences. The proteome is an important complement to the genome and transcriptome, and together they create a more complete resource for researching health and diseases. While genes determine many of our characteristics, they’re able to do that by providing instructions for making proteins. So these draft maps -- which you can think of as the Human Genome Project for proteins -- consist of profiles of proteins expressed in all sorts of different human cell types.

Lab: Gas Exchange in Respiration Gas Exchange in Respiration: Qualitative Observation of Carbon Dioxide Release It is the time of year for teaching photosynthesis and respiration to my biology students. I think that all biology teachers will agree that these are difficult concepts to teach to our students. Other than genetics, I think that the topics of photosynthesis and respiration may be my favorite topics to teach. I enjoy the chemistry aspects, and I especially enjoy sitting back and marveling at how beautiful these two processes are. LAB: USING CABBAGE JUICE TO OBSERVE CO2 PRODUCTION IN CELL RESPIRATION Make your science class more fun and interesting by incorporating lab activities into your daily and weekly lesson plans. My students particularly love this lab because it uses red cabbage juice as an acid/base indicator to detect the carbon dioxide that is released during cellular respiration. Carbon dioxide is released during cellular respiration and is given off as a waste product.

Foldables in Science This is not a science specific resource, however, as an elementary teacher of science and as a professional development provider I have used Foldables to help learners better understand science concepts. If you are new to Foldables, they are essentially folded paper used as a graphic organizer. There are many flavors of Foldables: Cause & Effect, Venn Diagrams, mini-books, and more. If you found this post by searching for science & foldables, I would ask that you check out some of my other posts and add this blog to your science education bookmarks.

Poster «The Ebola Virus» The Ebola virus and it’s close relative the Marburg virus are members of the Filoviridae family. These viruses are the causative agents of severe hemorrhagic fever, a disease with a fatality rate of up to 90% [12]. The Ebola virus infects mainly the capillary endothelium and several types of immune cells. The symptoms of Ebola infection include maculopapular rash, petechiae, purpura, ecchymoses, dehydration and hematomas [13]. Since Ebola was first described in 1976, there have been several epidemics of this disease.

Anatomia Vegetal Visualising the Cell Nucleus Leaf growth Cell growth Cell organelles and cytoplasm visualisation Cell membrane and cell wall growth Dicotyledon* stem cross-section Whole organ 'grown' in world first A whole functional organ has been grown from scratch inside an animal for the first time, say researchers in Scotland. A group of cells developed into a thymus - a critical part of the immune system - when transplanted into mice. The findings, published in Nature Cell Biology, could pave the way to alternatives to organ transplantation. Experts said the research was promising, but still years away from human therapies. The thymus is found near the heart and produces a component of the immune system, called T-cells, which fight infection. Grow your own

Who wants to summarize using foldables??? I love foldables. They can take the most mundane of material and liven it up so that the kids are meaningfully engaged and learning. As the year has progressed, I find myself using more and more of these little pieces of paper in my classroom. My latest craze has been to use them in science.
