They have special features that make them ideal organisms for scientists and engineers to use in a wide ranage of applications ranging from medicine to environmental and energy engineering. When we study bacteria closely, we find that they fascinating organisms. People generally think that bacteria are bad for us or dirty, but in reality, many different types of bacteria are essential and beneficial to us. Well, microorganisms are all around us, and we can even study how quickly they grow.Īt the end of this activity, you will know what specific factors influence the growth of microorganisms, such as bacteria, and know what effects these various factors have on bacteria. Have you ever noticed blobs of mold or strangely colored microorganisms around your house? These strange organisms might have shown up in suspicious looking food or in a pink ring around the water in a (dirty) toilet bowl. Organisms, and populations of organisms, are dependent on their environmental interactions both with other living things and with nonliving factors.Īlignment agreement: Thanks for your feedback! In any ecosystem, organisms and populations with similar requirements for food, water, oxygen, or other resources may compete with each other for limited resources, access to which consequently constrains their growth and reproduction.Īlignment agreement: Thanks for your feedback! Growth of organisms and population increases are limited by access to resources.Ĭause and effect relationships may be used to predict phenomena in natural or designed systems.
Phenomena that can be observed at one scale may not be observable at another scale.Īlignment agreement: Thanks for your feedback! Engineering advances have led to important discoveries in virtually every field of science, and scientific discoveries have led to the development of entire industries and engineered systems.Īnalyze and interpret data to provide evidence for the effects of resource availability on organisms and populations of organisms in an ecosystem.Īnalyze and interpret data to provide evidence for phenomena.
An organism may consist of one single cell (unicellular) or many different numbers and types of cells (multicellular). This activity focuses on the following Three Dimensional Learning aspects of NGSS:Ĭonduct an investigation to produce data to serve as the basis for evidence that meet the goals of an investigation.Īlignment agreement: Thanks for your feedback!Īll living things are made up of cells, which is the smallest unit that can be said to be alive. Describe the conditions and requirements that bacteria need to survive.Ĭonduct an investigation to provide evidence that living things are made of cells, either one cell or many different numbers and types of cells.Ĭlick to view other curriculum aligned to this Performance Expectation.Explain generally where bacteria can be found.Plot data and determine their significance.Determine, based on data analysis, the best way to keep bacteria off our hands.Describe the potential positive and negative roles bacteria play in our lives.Knowledge of the growth rates of bacteria is essential for these types of engineers in order to use the microorganisms in valuable ways for human and ecological life.Īfter this activity, students should be able to: Bacteria are also used by environmental engineers as an ecologically-friendly way to digest (literally, to eat) the carbohydrates in oil from off-shore oil spills. Biochemical engineers genetically modify the DNA in bacteria to produce "designer proteins," and proteins to treat diseases, such as cancer or to act as new materials enabling the conversion of solar energy to useable electricity. Biological, environmental and biochemical engineers must have a thorough understanding of bacteria in order to use these organisms in devising new treatments for diseases, better oil spill clean-up, and the production of alternative energy forms. However, many bacteria are beneficial to humans and useful (even essential), as well. The word bacteria often brings up negative connotations related to illness and disease.
