Welcome to Science Lesson Resources for Teachers and Parents!

 Turns out, we do not see the absolute values of colors.  We always take into account the shadows. Let's see this video to understand how it works https://drive.google.com/file/d/11KMDfT-AGgnSuJ_tYJ5M53K7q8B56acK/view?usp=drive_link

 Here are some 3 cool experiments that you can do in class if you have a laser pointer. One of them shows that light is not just a stream of particles/ photons, but a wave at the same time. 1. Laser does not spread out with distance the way the flashlight beam does 2. You cannot see a laser beam from a side. You need a mist to disperse it 3. The famous "double slit experiment"   There is only one hard word that we have to learn today - Diffraction .

 See how do waves bounce from the walls and form different patterns. https://www.youtube.com/watch?v=Q8P4iL6ZafQ

 Each color has many shades. Some are very beautiful. These shades are very popular.  Choose - which once of them you like the most: https://www.eggradients.com/blog/pretty-colors Anodized titanium can have many different shades, depending on the voltage of the electricity used. This coating is cheap and stable. Which shade do you like the most?

 1. Find Namibia on the map 2. Listen to the click sounds on the web site: https://www.ipachart.com/ Here is a web site with probably all the sounds that people make in the languages around the world. Have you noticed that English has different B and P sounds, while Arabic has ء ع, and ظ, like in word "Abu Dh abi"? And some languages use the distinctive click sounds 3. Try to say/ pronounce some click sounds 4. See a video with a fluent use of the click sounds: https://www.youtube.com/shorts/Q5H3TPoN7Qo As you can see, the click sounds do not interrupt their speach

     Sound is a vibration. It can travel in air . You also can hear sounds under water and through solids .  But sounds cannot travel through vacuum or outer space.  Let's do some easy experiments ourselves to prove the above statements!
