Title: |
Surviving the Extremes |
| Subject: |
Science,Biology |
| |
Grade: |
9 |
| |
Description: |
This lesson is designed to introduce students to the homeostatic functions of the cardiovascular system. Students explore temperature and blood pressure regulation in the human body in extreme environments, the mechanisms by which they are maintained, and the damage that can be done when the body is pushed beyond its limits. Topics covered in this lesson include: the components of the cardiovascular system, the function of capillaries in regulating body core temperature, what blood pressure is, factors that influence blood pressure and body temperature, and the homeostatic control of both. A laboratory exercise using probeware allows students to gather data on changes in their own core body temperature when environmental temperatures change. They develop hypotheses, construct a scientific model, and collect and interpret data. Lastly, students utilize the information gathered in the laboratory to explain what happens when the body is pushed beyond it’s limits and undergoes d... |

Title: |
Terra Aqua Ecocolumns |
| Subject: |
Science,biology,environmental science |
| |
Grade: |
9,10,11,12 |
| |
Description: |
Students create three chambered eco columns that contain 1) an aquatic chamber, 2) a decomposition chamber, 3) a terrestrial chamber. They monitor the progress of the interconnected ecosystems over a 2-4 week period. Students take quantitative data using salinity probes, oxygen probes, pH meters, and water and soil quality test kits (La Motte). Students also take daily photographs of their pictures and create a video lab report of the changes of their ecocolumn over time. ... |

Description: |
Bug Builders, Inc.
1) Introduction
Imagine that you are a designer for a toy company that makes toy alien bugs. The president of Bug Builders, Inc., wants new versions of the wildly popular Space Bugs, but he wants to use the bug parts that are already in the warehouse. It’s your job to come up with a new bug design. You have studied how traits are passed from one generation to another. You will use this knowledge to come up with new combinations of traits and assemble the bug parts in new ways. Model A and Model B will act as the “parent” bugs. The two models currently available are shown .

Title: |
Are Humans Still Evolving? |
| Subject: |
Science,biology |
| |
Grade: |
9,10 |
| |
Description: |
The lesson begins with students' viewing of a short caroon clip about natural selection and a quick follow up discussion.
Students then watch National Geographic "Was Darwin Wrong? Part III" They will take notes with the assistance of the instructor
They will then proceed to do an inquiry lab, in which students realize that certain variation in characteristics can increase
their survival chances.
This is followed up by a guided instruction segment where students practice their newly acquired knowledge using the proper vocabulary.... |

Description: |
This is a Gradual Release of responsibility (GRR) modeled lesson. The lesson begins with a short video followed by a talk-aloud focus lesson by the instructor.
It is then followed by guided instruction, in the form of a simple lab. Students experiment with changes in their body temperature.
This is followed by students making graphic organizers of various homeostatic situations.(collaborative group work)
For the final section, students, individually, answer follow up questions on the lab worksheet.... |
