The Periodic Table of Elements

11/30/2018

In class today our good buddy Hank Green told us the history of the Periodic Table of Elements. We added group numbers and names to our tables and then began building model molecules using ball and stick kits.
Gold Tape Question: Print out and build a papercraft periodic like the one Hank shows in the video. You can check out the link here.

Come on and Meet the Elements!

11/29/2018

Today we watched a fun video called "Meet the Elements by the band They Might Be Giants to kickoff our study of the periodic table of elements. Then students color coded their own periodic table shading the metals, non-metals, and metalloids.

Physical and Chemical Changes Stations Lab Day 1

11/27/2018

In class today students began working through their chemical and physical changes lab stations. They will finish these lab stations tomorrow.

Welcome Back

11/26/2018

In class today we revisited the differences between chemical and physical changes as well as watched a video about the five most dangerous chemicals ever developed. Tomorrow we begin a two day lab further investigating chemical and physical changes.

Chemical and Physical Changes

11/15/2018

The last two days in class were spent discussing and investigating chemical and physical changes. If you missed class you can catch up on these concepts with the two videos below.

Chemistry Lab #1

11/13/2018

In class to day we conducted The Rainbow Lab in which students practiced following instructions and measuring liquids. Students created a test tube rainbow with their results. This is the first of many chemistry labs we will do in class.

Chemistry and Lab Safety

11/12/2018

Tomorrow is our first chemistry lab. In class today we discussed and watched a video about lab safety. Students signed a safety contract agreeing to follow all lab safety protocols.

Evolution Unit Complete Monday We Begin Chemistry

11/11/2018

With our test last Friday our evolution unit is complete. Monday we begin our Chemistry Unit which will take us up to Winter Break.

Gold Tape Question: Read THIS ARTICLE about how elephants are continuing to evolve and write a short summary about: 1) What adaptation is occurring in the elephants? 2) What is causing this adaptation to rise in the population? 3) How does this adaptation help the elephants survive? 4) How do you think African elephants might look in 10, 20, or 30 years?

Relatedness and Evidence of Evolution

11/6/2018

Today we finished our investigation of other methods of relatedness. We found that there are many different ways that we can observe how organism are related to each other and all of these ways are further evidence of biological evolution, that all organism evolved from common ancestors.

Other Methods of Relatedness

11/5/2018

Homologous Structures

Today was day one of two investigating other methods of relatedness among organisms. So far we have focused on how organisms that are similar to each other tend to look similar. However, there are many other ways to compare relatedness including homologous, analogous, and vestigial structures as well as the type of cell that makes up an organism. Tomorrow we will share out what we've learned with our partner groups and continue our discussion of relatedness among all organisms.
