Teacher Demo Box
Welcome to all teachers. We hope you have the ThinkTac “Demo Box” handy! Within it, you will discover unlimited fun and exploration possibilities that belie the nifty size of the box itself. And that is the wonder of science: it’s possible to enjoy, engage and learn it with very simple materials, and all in the raw form!
This fun-filled box of a diverse group of 6 experiments can cover various topics taught in school level science across all curricula. The Play Card illustrates very effectively and pictorially the instructions required to undertake each activity (which we call “TACtivity”, as all our activities are Tactile Activities). Detailed instructions are available on our website (Links in the table below) as well as on our YouTube Channel. An overview of the contents of the Demo Box, and a quick sample demonstration of a selection of the TACtivities, are also available on YouTube.
Magnetic forces, along with friction and gravity, can be experienced and understood by making a marvellous vertically-standing pen stand, using a bicycle spoke and a CD base. You will also get to observe a stained slide of an onion peel through a simple microscope, made using a spherical and clear glass bead, which acts brilliantly as your converging biconvex lens. The ingenious design allows you to explore any number of samples with the microscope, e.g. leaf venations, cloth fibres, cheek cells, fungi, pollen, the RGB LED grid of any modern device screen and a lot more…
An ingeniously designed “Straw Propeller” is a powerful tool to demonstrate Newton’s Laws of Motion as well as various aspects of rotational mechanics. Made with straws of two different gauges, this versatile toy is a joy to play with and explore the nuances of some very fundamental concepts in physics. Acids and Bases can be explored in-depth right in your kitchen, using turmeric as the acid-base indicator. Get yourself a selection of household acids (e.g. vinegar, lemon juice etc) and bases (lime powder, baking powder etc), and you can conduct a series of experiments, ranging from titrations and neutralisations; to categorising any and every solution / liquid mixture in your house into “acidic”, “basic” or “neutral”. You’ll be amazed by the results of where food items fall!
Did you ever realise it is so simple to make your own speaker? Well, you have one with you in your kit! Made just with a small (and powerful) magnet and some enamelled copper wire, you can connect the audio jack to any electronic device audio outlet and listen to your favourite tracks! Any electrical signal sent in a wire converts that wire into an electromagnet, which then interacts with a permanent magnet resulting in the movement of the metal wire: an up-and-down vibration that is captured by the container/membrane that the coil is attached to, and this vibration, happening tens or hundreds or thousands of times per second is what we hear as sound! You also get to “make” your own battery using two metals, a separator and an electrolyte. Through this TACtivity, you can not only delve into the world of series and parallel circuits, but also into the intricacies of electrochemistry, replete with possibilities, as you can vary the materials of the electrodes, separator, electrolyte, its concentration etc.
While these remarkable TACtivities will definitely leave you asking for more, they themselves may well be that path of where you find a lot in very little.
