LS1.D: Information Processing
• Each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain. The signals are then processed in the brain, resulting in immediate behaviors or memories. (MS-LS1-8)

l. Goals:

1. Understand that each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain.
2. Understand that the signals are then processed in the brain, resulting in immediate behaviors or memories.
NGSS Note: Think, question, entertain ideas.
 
ll. Introductory Activities to Assess Prior Knowledge about Structure and Function
A. Simple Activities - that assess students’ understanding of sensory receptors.
Sense Organs of the Skin - Fill in the Blank (Advanced)
Sense Organs of the Skin Matching
Sense Organs of the Skin - Name Functions (Advanced)

Question: What are some examples of electromagnetic, mechanical, chemical sensory stimuli animals recieve and to which they act upon?
1. Break students down into groups of 3-4.
2. Ask students to generate a list of different sensory stimuli (electromagnetic, mechanical, chemical) that animals receive and respond to (i.e. smell, temperature change, etc.)

V. Summarize Knowledge - Enduring Understandings
1. Understand that each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain.

2. Understand that the signals are then processed in the brain, resulting in immediate behaviors or memories.

Science and Engineering Practices

Obtaining, Evaluating, and Communicating Information
Obtaining, evaluating, and communicating information in 6-8 builds on K-5 experiences and progresses to evaluating the merit and validity of ideas and methods.
• Gather, read, and synthesize information from multiple appropriate sources and assess the credibility, accuracy, and possible bias of each publication and methods used, and describe how they are supported or not supported by evidence. (MS-LS1-8)

Crosscutting Concepts

Cause and Effect
• Cause and effect relationships may be used to predict phenomena in natural systems. (MS-LS1-8)
• Phenomena may have more than one cause, and some cause and effect relationships in systems can only be described using probability. (MS-LS1-4),(MS-LS1-5)

Performance Expectations Students who demonstrate understanding can:
MS-LS1-8. Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories. [Assessment Boundary: Assessment does not include mechanisms for the transmission of this information.]

Citing Research References

When you research information you must cite the reference. Citing for websites is different from citing from books, magazines and periodicals. The style of citing shown here is from the MLA Style Citations (Modern Language Association).

When citing a WEBSITE the general format is as follows.
Author Last Name, First Name(s). "Title: Subtitle of Part of Web Page, if appropriate." Title: Subtitle: Section of Page if appropriate. Sponsoring/Publishing Agency, If Given. Additional significant descriptive information. Date of Electronic Publication or other Date, such as Last Updated. Day Month Year of access < URL >.
