Observing Beyond our Senses – Career Connections Summarized

Within each OBOS lesson, there are outlines of career-connected activities that can be incorporated into the lesson. These can be located in the Career Connection Tab within each lesson page. In the table below, you will find a compiled list of options for teaching all of the career connected activities for the entire module. For each lesson, we have identified 4 options – choose an activity based on the time…

Death Valley Community Meeting Role Play

To conclude the career activities of the Observing Beyond our Senses module, we suggest students role play a “Town Hall” community meeting. Students should have learned enough content and done enough guided interview work to be able to stage a “Town Hall.”  A Town Hall is a community meeting attended by a wide variety of constituents who speak about a topic while representing their point of view and specific interests….

Lesson 6 – Death Valley Middle Basin Case Study

Measurements of indicator species can be used to make inferences about environmental conditions. Quantity and resolution of a data collection plan is limited by resources. Mine tailings are point sources of heavy metal pollution.

Lesson 5 – Inferring Properties and Calibration

This lesson serves as the conceptual underpinning for understanding how light behavior can be used to measure concentrations with a spectrophotometer. Students should frame their observations around “particles” of light interacting with material in three observable ways: that light can pass through, bounce off, or be taken in by materials.

Lesson 4 – Signal and Noise

In this set of activities, students will attempt to communicate using hand signals or assemble an operational amplifier to play their iPods through a small speaker. The focus of activities will be the concepts of signal and noise and the trade-offs involved in amplifying the signal.

Lesson 3 – Inferences from Proxy Variables-Mock AFM

Observation is the skill of recognizing and noting some fact or occurrence in the natural world. Observation includes the act of measuring. To infer is to arrive at a decision or logical conclusion by reasoning from evidence. Scientists use observations to make inferences.

Lesson 2 – Design Process-Measuring Wind Speed

his introductory activity has students quickly cycle through a complete design procedure centered on a measuring challenge. Specific aspects of a design procedure, such as defining criteria or evaluating trade-offs, will be practiced again in later instrumentation activities.

Lesson 1 – Introduction to Saline Environments & Microbial Halophiles

Environments of differing salinities form on earth. Human activities impact saline environments by altering the salinity and/or introducing pollution. Extremophilic organisms such as Halobacterium salinarum can live in high salinity environments.

Observing Beyond our Senses – Unit Plan

In this unit, students are confronted with increasingly complex examples to build an understanding of how scientists measure what we cannot directly observe with our senses. Trade-offs in instrumentation design and generating meaningful inferences from observations are overarching themes connecting the activities.
