Science Lessons

The science learning cycles of the PULSE curriculum form the basis for developing student understanding of environmental health and biomedical concepts. These lessons are supported by the social studies, math, and language arts lessons in several important ways. These lessons develop necessary understandings of biology, chemistry, earth science, and physical science to master the information nedded to complete the major projects. The national science education standards developed by the National Committee on Science Education Standards and Assessment, National Research Council were used to align the lessons.

The National Committee on Science Education Standards can be viewed at: http://www.nap.edu/readingroom/books/nses/

The lessons address many of the eight categories of content standards

• Unifying concepts and processes in science
• Science as inquiry
• Physical science
• Life science
• Earth and space science
• Science and technology
• Science in personal and social perspectives
• History and nature of science


Lessons in Alphabetical order: A-D, E-M, N-S, T-W.

Mini-Unit/lesson
Description of Mini-Unit/Lesson
Oh Those Sandy Beaches
--
On the Microbe Trail: Bacteria and Aseptic Technique Students practically explore and explain why they need to use aseptic techniques as they learn those techniques.
This lesson introduces students to the forces involved with like and unlike electrical charges.
Pollutant Posters

During this lesson students will apply their understanding of weather systems, air currents, and pollution to create an informational poster that will be presented in a mini science forum.

Pollution Over Where? In this lesson, students will predict the movement of an air borne pollutant using their understanding of air currents.
Power-Who Needs It?

The reading for the lesson is from July 4, 2004 from the NY Times. The information provided should be appropriate for a very long time.

Protecting the Herd This activity introduces students to modeling as a scientific exercise. Students learn how models based on observations of disease transmission can be used to predict the likelihood of epidemics and to help public health officers recommend policies to protect the public from infectious diseases.
Protein Synthesis and Words But what do genes actually do? During this lesson students learn about the roles of the mRNA, ribosomes, tRNA and how the cells synthesize proteins.
Putting on Mass: Just how do Trees grow? Students discuss van Helmont’s experiment and identify what they know about plant nutrition.
Rain Shadows and Sea Breezes

Where toxicants of environmental health importance are transported through the air, understanding the natural processes, which contribute to air movement and weather patterns of a region, is important.

Reaction --
Reading your Water Students return to their water bill and look at the local water utilities quality report.
Renewable vs. Non Renewable Energy --
Routes of Entry Student groups are given a set of stories describing different diseases and they have to classify each disease as pathogenic, non-pathogenic, beneficial, and put it into its’ proper place on a chart of the four microorganism types.
Skin cancer in trial

In this engage lesson, students will be introduced to clinical trials via a scenario and will begin to read articles about clinical studies associated with skin cancer.

In this explain/apply lesson, students will be given the opportunity to design an experiment looking at the ability of different substances to interfere with the transmission of UV rays from different sources.

Sugar and carbohydrates, protein, fat and water - that’s what little plants are made of! Students connect the chemicals that make up cell parts with the processes that get them there, photosynthesis and respiration.
Sugar and Light Light as an essential part of the photosynthesis process is addressed in this classic lab using geraniums and Lugol’s Iodine.
SuperBugs and Antibiotic Resistance Through laboratory experimentation, students test antibiotics and/or antimicrobials to determine how quickly a given bacterium develops resistance to antibiotics and/or antimicrobials.
