Betty, the robot cleaner


Introduction: 
In this tutorial you ill learn what is a circuit. An electric circuit is like a pathway made of wires that electrons can flow through. A battery or other power source gives the force (voltage) that makes the electrons move. ... The wires have to go from the power source to the device and back again, so that the electrons can go out and come back.

Circuit Diagram

Aim: 
To build a  mini-robot that will help someone clean a tiny area in their home. (maybe you can create a big robot)

Materials: 

 diy robot

 2 x bits of wire, 
1 x 3v motor, 
1 x AA battery, 
3 x beads (a third one too if wanted), 
2 x pieces of foamboard (or more if desired), 
Some legs,
A Hot Glue Gun.

 Method:

1. Connecting to your Motor: You can either “twist” them on or solder them on. Soldering will probably give your little robot more longevity, but isn’t strictly necessary.
Take your pieces of wire and solder one of each onto a metal contact on the motor. This is quite fiddly so be careful. The best technique is to hold the iron on the metal Contact and bring the solder towards it, letting it melt onto the  contact and form a seal. Make sure that you frequently wipe the solder iron with a sponge to get any burnt solder off it. /in my kit, this is done for you).

 2. Securing the battery to your motor: Glue the bigger piece of foamboard onto the Motor with the metal contacts at the top. Glue the bigger piece of foamboard onto the Motor with the metal contacts at the top.

 3. Unbalancer: Now this step may seem a little random.. but what you are doing is “unbalancing” the motor, which in turn creates the movement of the little thing. So make sure you don’t skip this bit! Glue a small piece of foam board onto the end of the motor to help unbalance your robot. You can also stick a bead on if you wish. Leave this all to dry for a couple of minutes.

 4. Legs: You now need to stick your robots legs onto the bottom of the motor. If using toothbrushes, you might want to stick some foamboard in between. Leave to dry for a couple of minutes.

At this point your little robot should look something like this.

5. Connecting to the Battery: Using your hot glue one of your wires to one end of your battery, your choice which one. It is very important that you create a contact between the wire and the battery – too much glue and you will seal the wire.
















6. Eyes: Now stick your robot’s eyes on the appropriate end of the battery. Either end is fine, just choose and end that you like!

7. Final Connection: Now to make your robot move! Take your second wire and stick it to the non wired end of your battery using some tape. By doing this rather than using the glue gun you have flexibility on when the motor is on or off.

Gummy Bears on Fire!

Image
As this was more fun to do then video, we found an old video on YouTube to give a demonstration. This was fun, exciting and awesome to do!! In this experiment, a demonstration of a spontaneous exothermic reaction will take place between a gummy bear and molten potassium chlorate. Once the potassium chlorate has been melted in a test tube, a gummy bear will be dropped to his doom and flames will burst out of the tube as a result. Materials:  1. Safety first! Wear safety glasses  2. Plastic Shield  3. Gummy Bears  4. Potassium Chlorate (About 5-7 grams)  5. Pyrex Test Tube  6. Ring Stand with Clamp  7. Bunsen Burner  8. Matches  9. Tongs  10.Fume Hood or Snorkel Safety:  WARNING! Do not stand near experiment, and always remain on the outside of the fume hood. Viewers must stay behind demonstrators at all times for safety precautions. Those who are sensitive to light should avoid this demonstra...

Briggs-Rauscher Reaction

Image
Having fun as always in my chemistry lab!!This with 15-17 year olds in a workshop INTRODUCTION The Briggs-Rauscher reaction, also known as 'the oscillating clock', is one of the most common demonstrations of a chemical oscillator reaction.  The reaction begins when three colourless solutions are mixed together. The colour of the resulting mixture will oscillate between clear, amber, and deep blue for about 3-5 minutes. The solution ends up as a blue-black mixture. SOLUTIONS Solution A: Add 43 g potassium iodate (KIO 3 ) to ~800 ml distilled water. Stir in 4.5 ml sulfuric acid (H 2 SO 4 ). Continue stirring until the potassium iodate is dissolved. Dilute to 1l. Solution B: Add 15.6 g malonic acid (HOOCCH 2 COOH) and 3.4 g manganese sulfate monohydrate (MnSO 4  . H 2 O) to ~800 ml distilled water. Add 4 g of cornstarch. Stir until dissolved. Dilute to 1l. Solution C: Dilute 400 mL of 30% hydrogen peroxide (H 2 O 2 ) to 1 L. MATERIALS 300...

Explosion boxes

Box example Explosion Boxes If you love pop-ups – those playful, joyful constructions that bring books and cards to life –  then you will enjoy making “ explosion boxes .” These popular 3D paper crafts take pop-ups to a  whole new world. Like pop-ups, “explosion boxes” offer an engaging way to invite students into the world of  math and engineering. They encourage students to explore and work with measurement, parallel  and perpendicular lines, angles, triangles, symmetry, and transformational geometry, all in the  context of engaging students to design and make themselves. Although the deepest learning comes when students design from scratch,  The simple explosion box shown here is designed to enclose a small Valentine’s Day treat, gift, or note.  It can be printed first and then cut, or cut without printing from coloured card stock or plain white paper  that students decorate themselves. Box Example ...
