Middle and High School … from a Montessori Point of View
Are the elements of larger atoms harder to melt than those of smaller atoms? We can investigate this type of question if we assume that bigger atoms have more protons (larger atomic number), and compare the atomic number to the properties of the elements. Data: Properties of the First 20 Elements Question 1. Your job … Continue reading “Atom Size and Element Properties?”
These atom boards worked very well for practicing how to interpret atomic symbols. The protons (blue) and electrons (red) are magnetic so they snap into place quite satisfyingly. Their poles are oriented so that the electrons will only attach properly to the slots in the electron shells and the protons only attach the right way … Continue reading “Atom Board: Montessori Work”
A couple of my students asked for worksheets to practice drawing atoms and electron shells. I updated the Atom Builder app to make sure it works and to make the app embedable. So now I can ask a student to draw 23Na+ then show the what they should get: Worksheet Draw diagrams of the following … Continue reading “Updated Atom Builder”
Because we have the opportunity to get a few rabbits, we’re starting Biology this year with anatomy. In the first week, our discussions will be based around the rabbit dissection so we’ll be focusing on the systems where the organs are easiest to find: the fluid regulation/excretory, respiratory, cardiovascular, reproductive, and digestive systems.
The electron cloud surrounding an hydrogen atom shows the shells quite nicely. Via Science.
A neat stop-motion movie made by manipulating individual atoms. This is a great spark-the-imagination video because you can use it to talk about the physics of atoms and molecules, and what is temperature — they had to cool the atoms down to 4 Kelvin to keep them from moving too much. How they did it: … Continue reading “A Movie in Atoms”
A look into the imaging of large molecules (chromosomes) and the arrangement of atoms in really small particles.
This app lets you drag and drop electrons, protons, and neutrons to create atoms with different charges, elements, and atomic masses. You can also enter the element symbol, charge and atomic mass and it will build the atom for you. Note, however, it only does the first 20 elements.
