Today's Quote:
Recap:
After all of the confusion with county in- services we finally got back on track. Yesterday the students finally got chance to explain Precision and accuracy. The two can best be summed up with this graphic:
High precision is when all of your observed or recorded data is grouped closely to each other measurement, but not necessarily near your expected or target data.
High accuracy is when all of your observed or recorded data is near your target data, but may not be grouped closely to the other observed data points.
In science, we strive for both high precision and high accuracy.
Following today's discussion of calculating percent error, students will practice with these concepts.
Accuracy, Precision and % Error worksheet. Due at the end of class.
Brain Bender:
It is impossible for anyone to survive longer than one week without drinking non- alcoholic fluids, yet Ronny managed a ten-day desert crossing without finding any water or bringing any along. How was this possible?
Agenda:
(This should be written in your planner every day)
1. Review Accuracy and Precision
2. Discuss calculating percent error.
3. Lab: 6th and 7th grade: Conversion factors. It is important to be able to convert between different units and especially between the SI (System Internationale) or what Americans call the metric system and our standard or Imperial system of measurement. 8th graders will do a similar lab, only we will also collect data on heating a water sample with the end goal of creating a data table and graph.
4. Lab safety Rap and review lab safety equipment locations
Homework:
If you have not read these two articles and taken notes over them, this is your homework this weekend!
Where Did Science Come From? Read through this article.
Review Power Point What is science? What isn't Science? What looks like science, but really isn't science.
6th Grade Honor's Earth Space Science:
6th Grade Class Information and Syllabus
Unit Essential Question:
What are the basic ideas behind the process of science?
Key Learning Statement:
Science is a process based upon observational and experimental studies using scientific methods to develop or explore scientific theories or laws.
7th Grade Honors Life Science
7th Grade Class Information and Syllabus
Unit Essential Question: What methods do scientists use to answer questions and solve problems in the natural world?
Key Learning Statement: Scientific inquiry involves forming a testable hypothesis and developing a valid investigation using scientific skills and tools to determine if the hypothesis is supported or not supported. Data from scientific investigations helps scientists explain natural events through the use of scientific theories and scientific laws.
8th Grade Honors Physical Science
Unit Essential Question: What is required to carry out a valid scientific investigation?
Key Learning Statement: A valid scientific investigation uses prior knowledge, observations, and empirical evidence to test a hypothesis and draw conclusions that must be validated through repetition and replication.
