Tinker Nest

  In this STEM activity, students will learn about tension as a force and how it acts on structural components through a hands-on group design problem. Through this activity, the students are excepted to learn about force and tension and their balancing. When the ends of the thread are tied to the pencil and the nail, a tension will be created on the string and as a result, the pencil cannot fall on the side opposite to the nail where it is tied. But, still, it can fall on the remaining three sides. So, now if we tie a thread to these remaining three sides, the force or tension created by the threads will be balanced and pencil will be able to stand upright. For their final task students will be instructed to balance a pencil upright with the help of the given materials. Sample video of the final task:  https://youtu.be/IlnkYlTOlb8 Objective : Introducing Class 4 & 5 students to the concept of Tension force. The Tug of War Students will be taken to the field for a three-ro...

Many of us love dice. We love to chuck them on the table, sometimes so hard that it rolls off onto the floor. Dice are the heart of almost all the board games and in this project, I tried it to make even more fun. I'm in grade 6 and as a part of my curriculum, I recently completed the basics of Tinkercad. I made this Dice in  3D Design  as part of my assignment and after that, I tried to push myself by recreating this using  Codeblocks . In this project, I'll walk you through how I created this Noisy Dice using Tinkercad Codeblocks . Things We Need   A Computer Tinkercad account 3D printer(Optional) Creating New Codeblocks Project Log into your Tinkercad account, and select  Codeblocks  from the toolbar on the left. Then select  Create New Codeblock . A new window will pop up. In the new window, select  New Design .  Making Cube Hollow For this Noisy Dice, we will first make a hollow cube. For this: Select the  Box block  from the...

Submarine operates using the Archimedes' principle by manipulating the buoyancy. Let's perform a simple activity to understand its operation. Things We Need Plastic bottle Glue gun Screwdriver Some Weights(You may use steel washers, nuts or castor wheel) Candle and matchbox 2 feet rubber tubing Water tub Activity Preparation Light up a candle and heat up the end of the screwdriver. Push the heated screwdriver through the bottle and poke 3 holes in it. Also, poke a hole through the cap on the bottle. Pass the rubber tubing through the bottle cap and water-tight it using a glue gun. Place the cap back to the bottle. Glue the weights near the holes using a glue gun. The Submarine Science Place the bottle in a water tub. The bottle will float. Now suck through the open end of plastic tubing. The bottle will start sinking slowly. Next, blow air into the bottle. What will happen? The bottle will start coming to the surface just like a submarine. So before dive into behind it, let...

  I learned to make ball hinges while I was designing a hand for my Servo Robotic Hand project. In this project, I will first make a Ball Hinge and explain how we can use it to make anything hinged with a hands-on on a Bat model that we will import or copy from the gallery. Things We Need Computer Internet Tinkercad account  Creating Ball Hinge Use solid box from Basic Shape menu and change its dimensions to Length = 15mm, Width= 15mm and Heignt= 10mm. Use hole box(transparent), change its dimensions to Length = 5mm, Width= 15mm and Heignt= 20mm. Place this box into the solid box(Pic Align them so that the sold box forms a "C" shape after grouping both of them. Group both the boxes by selecting both the boxes and group them(Ctrl + G). Now drag a sold sphere to the workplane. From Shape Menu change it to Hole and its Steps to 24(this will give it a smooth surface). The diameter of this sphere will be 9mm(or L=9, W=9, H=9). Align this hole sphere in the sold C shaped box and gr...

Making modeling clay structures is fun, but making them with light-up eyes and moving parts is even more fun. Clay modeling is one of the favorite activities of kids because kids like being messy. I thought it would be icing on the cake if they will see glowing light, running motor and sound of a buzzer on Clay. This hands-on learning can be easily done at home by using few materials. Clay has a playful nature, so kids can explore Electronic Circuits in a playful way. They will learn about Closed Circuit, Open Circuit, and Short Circuit. This hands on learning can be done by kids above 4 years. You can initiate or encourage curiosity just by asking this question : Do you know you can make creatures or things using modeling Clay that can light up, move and make a sound? Watch their ZEAL for the learning !! Things We Need A power source with a current value of 5 volts. I have used a battery of 9 Volts. Two wire leads with alligator clips on each end. Modeling Clay. Some finely grinded sa...

Whether you’re building a robot or working with Arduino, form "hands-on" electronics to prototyping of a project idea, knowing how to solder will come in handy. soldering is an essential skill to be learned if someone is really into electronics and making. Learning to solder is relatively straightforward but it takes a little bit of practice to become a master. In this project, I'll share how my kids enjoy learning and mastering this important skill. Things We Need You will need: A soldering Kit Perdboards Some electronic components like LEDS, resistors, etc Power Supply Soldering:  Soldering is a process in which two or more items are joined together by melting solder around the connections providing reasonably permanent but reversible connections. Solder Wire:  (Pic 2) It is a metal alloy which is usually made up of a Tin/Copper alloy(60% tin, 40% lead). It comes in both lead and lead-free variations with diameters of .032″ and .062″ being the most common. Due to enviro...
