The Atoms Family
We made a human atom. I printed of 10 of each: P, N, and E and photocopied them onto different colored paper. Here is our human nitron atom: (notice the electrons are running around the outside in wild abandon).
A brief periodic table trends activity for high school and genchem college students to learn about the 5 trends of the periodic table: ionization energy, electron affinity, metallic character, atomic radius, and electronegativity.
Decision Trees to review chemical compounds
Looking for a way to help students that are struggling with naming and writing compounds? Try this technique! It helped raise my students test average almost 20%.
Let me take a minute to take you back to May of last school year. As you can imagine, the end of the year is hectic. My third grade team would meet for an hour twice a week to go over report cards, end of the year activities, field trips, class lists, and purchase orders. Because I was the chairperson for third grade, I was in charge of leading the meetings and filling out the necessary paperwork. Ok, purchase orders. My teammates and I sat down and opened those gigantic vendor catalogs…
Homer-ostasis - Critical Thinking/problem Solving Skills, Collaboration Skills, Self-Monitoring And Self-Direction Skills
Keep The Level, Color And Temperature The Same In A Leaky Cup Of Yellow Yellow Water - Maintain Homeostasis To Keep 'homer' Alive. Keep the level, color and temperature the same in a leaky cup of yellow water - maintain homeostasis to keep 'Homer' alive! Homeostasis is traditionally a tricky concept to teach. This is a memorable and successful way to finally get this central need of life across to students with a fun challenge. It's tried and tweaked, easy to resource and links the lab to…

Organic Macromolecule Flowchart
This organic macromolecule flowchart walks the student through a series of questions to identify the 4 main organic molecules: carbohydrates, lipids (saturated and unsaturated), proteins and nucleic acids. Especially for students who struggle with organization and need concrete steps and scaffolding...
Freebie and Matter
This week in the lab all grades K-3 are working on matter. K is being introduced to matter. First grade is reviewing matter. One of my first graders said to another on the carpet this morning, "Can you believe my brother is in highschool and doesn't know that there are more then three states of matter?! He had never heard of plasma or Bose-Einstein condensate!" To this my other first grader replied, "I know, my dad (a highschool science teacher) says I know more than a lot of his students!"…
The atomic theory of matter tells us that a gas is made up of tiny particles called atoms (or molecules, which are combinations of atoms), which are constantly in motion, smashing into each other and the walls of whatever container they might be in. Here is a highly visual model of this idea.
