Nervous System Lab and Due Dates

Posted in 7th Grade at 4:33 pm by slesscience

7th Graders,

This week we will be conducting a lab called “Getting The Point: Skin Sensory Comparisions”. It is very similar to tests that doctors and nurses run to test for neurological disorders. While conducting the lab, please think about the sensory map of humans and the image above. It shows how one cross section of the cerebrum relates to your sense of touch. We will be building our touch receptor testers on monday.

-Mr. K

Reminder of Upcoming Due Dates:

Thursday: Assessment Sections 2 & 3; Skin Sensory Lab

Friday: Powerpoint & Model of Organ

Nervous System

Posted in 7th Grade at 9:29 am by slesscience

7th Graders,

Your Nervous System PowerPoint will be due next Friday. I know that some of you do not have computers at home so I will stay after school to let you work on the school computers if you give me warning. Most mornings I am here at 7:30 so come on up to use a computer then, too.

The reaction time lab will be due Friday. Here is what I need in the lab report

Name & Lab Title (Reaction Time Lab)

Purpose (Your Question)

Hypothesis (Your Educated Guess)

Analysis (Your Data Table & Calculation of Average reaction times for the 2 groups)

Conclusion (Was Your Hypothesis Correct?, What did you learn? Any Sources of Error?)

human to yeast about 30%

human to worm about 40%

human to banana about 50%

human to fruit fly about 60%

human to mouse about 90%

human to chimp about 98.4%

human to human about 99.9% (except for twins, whose genes are 100% identical)
