Exploring the Gyroscope

Image
     When something rotates fast, it doesn't want to change it's position.     This principle is used to build devices called gyroscopes. Gyro means "wheel", and scope "observation". In old times gyroscopes were used to observe the Earth rotation. The gyroscope will stay in the same plane, and as the Earth rotes, for us it will look like the gyroscope slowly changes it axis - one full rotation cycle per 24 hours, when in reality it's the gyroscope that stays in place, and we all, together with the house, and the whole Earth are moving.     Let's see what fun and surprising things you can do with a gyroscope.     Gyroscopes are not expensive. You can buy one, and try all of these experiments, and maybe come out with some new ideas for gyroscope tricks.

 Here are the 29 chapters that the students shall cover in their IGCSE Chemistry course under the Edexcel exam board. This shall be covered in two years, during year 10 and year 11. Year 10 covers chapters 1 till 15. Year 11 - chapters 16 till 29. Download a printable pdf from my Google Drive https://drive.google.com/file/d/1OqXgUIDtHMwOPKWiIJePM2mO703_tQcK/view?usp=drive_link

Periodic and Solubility Tables - Ready to Print and Laminate

Image
    This is a useful set for learning chemistry. You may print the periodic table on one side, and the solubility table on another, and then laminate the sheet to protect it.     These tables are colorful and printer-friendly and will not waste ink. These versions are the best I could find. I hope you will find them useful. Download the table from my Google Drive https://drive.google.com/file/d/1bPbBcHkGQrAJlPJqVBd1sk1SFdQlNUCn/view?usp=sharing Download the table in pdf from my Google Drive https://drive.google.com/file/d/1bPbBcHkGQrAJlPJqVBd1sk1SFdQlNUCn/view?usp=sharing

Introduction Chemistry - Team Building Activities

Image
 Here is a fun, student-centered activity that may be used to start the chemistry lessons at the beginning of the year.  1. The students form groups of 2 to 4 students 2. Each group gets a mineral and its name from the teacher 💎 3. The teacher asks "What is the periodic table? How many elements are there?" "And where do we get the elements from? Where do we get the chemicals? - From the ground, for free - you just take it." "Each country has different minerals. What minerals do we have in our country?" 3. The students research about their mineral in groups for 5-10 minutes, using their personal devices, take notes.  They may mention: The mineral's name Chemical formula, what elements are in it The uses The price - is it expensive? Interesting facts 4. The groups volunteer to present.  While some students speak, another walk between the desks and show their mineral to the classmates. In this way everyone will see each mineral. 5. The students clap each...

Chromatography - a Student-Centered Lesson - GCSE Chemistry

Image
 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...

How Do Waterfalls Form? 🏔️💦

Why is the atomic number marked with a Z

Image
  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 "
