This lesson uses centers to reinforce the five senses incorporating backyard science in the wonderful world of nature.
Students use their senses to describe what the weather is doing and predict what it might do next. After gaining a basic understanding of weather patterns, students act as state park engineers and design/build "backyard weather stations" to gather data to make actual weather forecasts.
Students are introduced to the concept of engineering biological organisms and studying their growth to be able to identify periods of fast and slow growth. They learn that bacteria are found everywhere, including on the surfaces of our hands. Student groups study three different conditions under which bacteria are found and compare the growth of the individual bacteria from each source. In addition to monitoring the quantity of bacteria from differ conditions, they record the growth of bacteria over time, which is an excellent tool to study binary fission and the reproduction of unicellular organisms.
Students construct paper recombinant plasmids to simulate the methods genetic engineers use to create modified bacteria. They learn what role enzymes, DNA and genes play in the modification of organisms. For the particular model they work on, they isolate a mammal insulin gene and combine it with a bacteria's gene sequence (plasmid DNA) for production of the protein insulin.
In this presentation, we talk about adaptation and evolution of bacteria. Furthermore, we will discuss how you can work with or against evolution, regarding the treatment of bacteria and biofilms.
In this presentation, we will discuss how bacterial pathogen adapt to the human host environment during long-term chronic infections. In continuation of this, we will discuss how the opportunistic pathogen - Pseudomonas aeruginosa - evolves during adaptation to the airways of cystic fibrosis patients.
This presentation introduces bacteria and biofilms. Where do we find bacteria? Is it possible to live without bacteria? Should we be scared of bacteria?
The aim of this presentation is to expand the student knowledge about biofilm properties. In continuation of this, we will present different models for testing and study a biofilm, hereby: the crystal violet assay, filter biofilm, the semi solid model, and the flow-cell system
this presentation focuses on host response to biofilm infection. In continuation of this, we will go through the different types of host response to infections, which consists of at least three components: the non-inflammatory defense, the immune response and the inflammatory response.
In this presentation we will focus’ on host response to chronic infections. In continuation of this, we will talk about the polymorphonuclear leukocytes (PMNs), the respiratory burst and reactive oxygen species (ROS).
this presentation focuses on the problems of treating chronic infections. Furthermore, we will discuss why the host defense seems to be not working probably. In continuation of this, we will discuss whether the problem with chronic infections will increase over the years.
In this presentation, we will introduce the mechanisms involved in the tolerance of biofilms to antibiotics. In continuation of this, we will talk about specific tolerance mechanism, oxidative stress and the development of mutational resistance.
This presentation introduces chronic wounds and the non-healing properties of these. In continuation of this, we will provide a brief introduction to bacterial biofilms in chronic wounds, furthermore we will introduce some of the controversies and challenges we face working with this subject.
The aim of this presentation is to expand the students’ knowledge about the chronic lung infection, Cystic Fibrosis. Cystic Fibrosis is probably the most studied biofilm infection and much of our biofilm knowledge derive from this disease.
In this presentation, we will talk about diagnosis of bacteria and chronic infections in clinical practices. We will discuss why we need to diagnose bacteria in infections and what the biggest challenges are in diagnosing bacterial and chronic infections. Finally, we will discuss what the future will bring, regarding bacteria and diagnosis.
In this presentation, we will introduce the student to diagnosis of chronic infections. Diagnosing chronic infections is just as complicated as treating these infections. In continuation of this, we will talk about the three main issues when diagnosing chronic infections and share some experiences we have within this area.
In this presentation, we will introduce you to evolution in biofilms and chronic infections. The general principles of evolution are independent of the specific environment, however some conditions related to time and space are faced by bacteria in chronic infections - and this affects evolution
In this presentation, we will tell you about social evolution in microbes and in continuation of this discuss why social evolution in microbes is important in biofilms.
In this presentation, we will discuss how bacteria are causing disease. Furthermore, we will introduce the student to the term pathogenesis, and in continuation of this present the four main steps, that causes pathogenesis.
The aim of this presentation is to expand the student knowledge about biofilms on central venous catheters (CVC). In continuation of this, we will discuss how to avoid infections regarding CVCs.
