Things to Know About Robotics Learning for Beginners

Robotics is an exciting and ever-evolving field that combines engineering, technology, and creativity to build intelligent machines. Whether you're a student, a hobbyist, or a parent guiding your child into robotics, understanding the basics is essential for a rewarding learning experience. Here are key things to know before diving into the fascinating world of robotics. 1. What Robotics Is At its core, robotics involves designing, building, and programming machines that can perform tasks autonomously or with minimal human intervention. Robotics integrates multiple disciplines, including: Mechanical Engineering: For designing the physical structure of robots. Electronics: For creating circuits and connections that enable movement and sensing. Programming: For writing the code that controls robot behavior. Having a basic understanding of these fields will give you a strong foundation as you start your robotics journey. 2. The Importance of Problem-Solving Skills Robotics is all a...

Home Made Lava Lamp

Do your own lava lamp and learn the interesting fact about density in science. It is a very interesting project which your kids enjoy for sure. Now Prepare yourself in a work area and wipe towel where you can easily clean up any spills.

Materials Required:

  • Clean glass or plastic container (If want more lava lamps take more bottles)
  • Vegetable oil
  • Water
  • Fizzing tablets (like the Alka-seltzer tablet)
  • Food coloring
  • Glitter if desired

Method

  • Take a bottle and fill half of it with water. Add vegetable oil into the bottle to make it full and leave some space on the top of the bottle. ( Use a funnel if you have it with you.)
  • Wait for some time and watch the oil and water get separated
  • Then add your favorite food color, you can see the food color slides through the oil until it mixes with the water. 
  • Then keep your fizzy tablet breaking into two half. Drop one part of the fizzy tablet in the bottle. You can see the bubble blobs.
  • Turn off the lights and drop another half of the fizzy tablet.
  • If you have the flashlight, shine the flashlight through the bottle with a lava lamp. You can see the blobs are bubbling.
  • Add glitters if desired you can see the glitters shining with the bubbles

Science Behind

Oil and Water have different densities. Oil is less dense (lighter) when compared with water hence it floats on top of the water. 

Food color has the same density as water hence it slides through the oil and mixes with water.

Fizzy tablet as it dissolves in water forms a gas named carbon dioxide.

Gas is lighter than water so, once the gas is formed it floats at the top bringing some food color with it. When the air gets released from the water blob, the water becomes heavier again and sinks.

A Lava lamp works with liquid that does not mix with each other. The real lava lamp consists of wax and water. The lamp inside heats the wax. The wax when melted becomes less dense and starts to float on the top of the water. As wax becomes cool it sinks down. This process repeats itself.

Experiment Further:

  • Try with different sizes of bottles.
  • Try with salt instead of the fizzing tablet
  • Try dropping fizzing tablets at once instead  of two half parts
  • Try different liquids with different densities

Different liquid has different properties to learn. Try mixing water with milk, juices, or food color, it mixes easily. But oil and water stay separated even if you stir vigorously it is all because of different densities. 

 

Hope you enjoyed the lava lamp. Keep learning with fun.

Growing Crystals

GROWING CRYSTALS Crystal is a solid material formed with atoms and molecules that are arranged in a consistent repeating pattern. This gives a definite shape to the crystals. Some of the crystals which are expensive are known to us like amethysts or diamonds. Do you wonder how crystals are found right in your kitchen? Yes, in the form of salt and sugar.  Crystals can be easily grown by adding a crystal-forming chemical to water and waiting for the water to cool or evaporate. Growing crystals is really a fun experiment for kids. They enjoy growing crystals in different and learn their science along the way. Let's see a few ways to grow crystals at home and engage kids with fun learning. Epsom Salt:   Epsom salt is inexpensive and readily available in the pharmacy or craft store.   It accepts food color as well if you want to grow colorful needle-like crystals.   It is non-toxic and crystals can be grown in a few minutes to an hour when the liquid is refrigerated.

Borax Pipe Cleaner Hanging Crystals

Borax Pipe Cleaner Hanging Crystals  It is a very interesting and fun activity of growing crystals with the chemical called Borax.  Borax is a chemical sold in the market as a laundry booster or an insecticide. It does not accept food coloring.  You can also use a pipe cleaner, bend it into fun shapes (stars, flowers, hearts, and more), and dip it into the borax solution overnight. You can see the crystal grow in the fun shape of pipe cleaners and get colorful crystals growing with the color of pipe cleaners. Required material: pan with a wide mouth Borax Pipe cleaners Water Tablespoon String Scissors Food coloring (optional) Methods to Grow Hanging Crystals Twist the pipe cleaners with your desired shape (like a star, flower, or any shape you desire) Take a wide-mouth pan such that the pipe cleaner easily fits into the jar with plenty of shape around it. (if not it will become harder to remove once the crystals are formed) Tie one end of the string into the shape of a pi...
