Welcome to Science Lesson Resources for Teachers and Parents!

 See the list of all the compounds with each element in a form of the periodic table. For example, let's go for the compounds of chlorine. Do you know how many different compounds between iron and chlorine exist?  What about sulfur?  How many different compounds do chlorine and sulfur form? Follow the link, and answer the questions https://en.wikipedia.org/wiki/Actinium(III)_chloride

 This useful website shows the electron configurations for all the elements in the periodic table . It can be used in group work activities when learning about the orbitals . https://www.webelements.com/carbon/atoms.html Here is a nice template to be filled by hand

 1. Introduction The teacher introduces the new topic with  intrigue , tells that chromatography is used in pharmacy and industry, and that the previous exams had many questions on this topic.  The students write down in their notebooks the topic and sketch the lesson summary diagram. The teacher introduces the two objectives of the lesson. 2. Sticky notes - brainstorming - Aha Slides The students show their previous knowledge and creativity . Each student contributes 3 words to the word cloud. 3. Virtual experiment - can be done in the lab also The students do the experiment first and then interpret the results, before learning the theory. This constructivist approach allows the student to think for themselves.  - Recap about why plants are green - See the experiment video for 30 second - Try it yourself This experiment uses the  I do - We do - You do approach. 4. Sample exam question The students together solve two questions about chromatography from the pr...

Why do waterfalls form?  Usually, the reason is not soft bedrock. The big river washes away sediments than its at tributary streams. This creates a difference in the elevation needed for a waterfall. Waterfalls Clearly Explained

  General Chemistry Online: FAQ: History of chemistry: Why is atomic number called "Z"? Why is mass number called "A"? Z symbol for atomic number probably comes from  German   " Zahl " (number). A - Atomic number" in German is " Atomzahl "

 Why the electron shells are called KLM not ABC? Orbital: px, py, pz - 2 electrons each Subshell: s1, p3, d5, f7 Shell: K s, L sp, M spd, N spdf  Here is a nice article explaining this. General Chemistry Online: FAQ: Electrons in atoms: Why are the shells named K, L, M, ... instead of A, B, C...?

 Let's find out how to measure the distance from Earth to any star. >>>>>>>>>  Parsec Parallax  <<<<<<<<<<<<<<<<< But first you shall know how to measure angles. 1. Read this: 90°11`41`` This is 90 degrees, 11 arcminutes, and 41 arcseconds 2. Is this correct? Why? 51°20`90``  No. Arcseconds and arcminutes cannot be greater than 60! 90`` -> 1`30`` 51°20`90`` -> 51°21`30`` Arc minutes and arc seconds are just like minutes and seconds on the clock!

 Fundamental knowledge means that you've learned a subject in a classical way, in the right order, with no gaps. For example , if you learn fundamentally about organic chemistry, you 1. learn the topics in the classical sequence:  alkanes, alkenes, alkynes; and then add functional groups: alcohols, aldehydes, ketones, acids, ethers, esters, amines, amides, proteins, and sugars. 2. understand the main concepts: nucleophile, electrophile, dative bond, Lewis structure, VSEPR Valence shell electron pair repulsion, etc. With fundamental knowledge you have a good foundation to build on, and you can understand specialists, have a common language with the scientists. Here are a few of excellent channels to explore and build Your knowledge fundamentally on each topic: 1 - Organic chemistry - 30 videos sequence, free Organic Chemistry Exam 1 Review - YouTube 2 - General Chemistry - all the elements in the periodic table by groups: Periodic Table Part 2: Alkali Metals (Li, Na, ...
