CO02DIY Multiple Test Tube StandSome experiments often require the use of a multiple test tube holder, useful for making comparisons and holding multiple test tubes side by side. Here, we make a test tube holder by making a loop using binding wire to hold the test tube and by wrapping the binding wire around an ice cream stick or any other object made from a poor conductor of heat. Make a slit in a foam base and insert the ice cream stick inside it to extend the test tube holder to a test tube stand. Add more slits and more test tube holders to make multiple test tubes stand next to each other.PACK OF 4PACK OF 10
CM02DIY CentrifugeA centrifuge is a device that uses rapidly spinning containers, to separate substances based on their density. The apparent centrifugal force pushes the denser materials to the extreme ends of the container while the less dense materials remain nearer the centre.

In this remarkable creation of Prof. Manu Prakash from Stanford University, we make a “centrifuge” using just cardboard, cotton thread, vials and a button. With one’s own hands, one can wind the thread and spin the cardboard at about 3000-4000 rpm, and easily separate certain colloidal mixtures, such as muddy water and even blood!
PL20DIY MicroscopeA microscope is an instrument used to observe very minute/small objects that are not visible to the naked eye. It consists of a diverging (convex/biconvex) lens, which enlarges the small objects to make it visible to the human eye.

In this TACtivity, we will make a microscope using glass beads (which act as the biconvex lens) and explore it by adjusting its focus to get a clear image and viewing some interesting objects.
CC14Food Test – ProteinThe food we eat contains various nutrients that are required by the body. One of these vital components is protein. Protein is one of the building blocks of life and essential in our diet. Using sodium hydroxide and copper sulphate, one can create a solution that is a good indicator to detect the presence of protein in a food substance. Here, we perform the test on a few daily life food items.
BP12Microscope – Leaf VenationObserving the veins on different kinds of leaves is a great way to not only appreciate how water and nutrients are transported in plants, but is also an effective tool in identifying plants and their types. In this TACtivity, you use your own DIY Microscope to observe leaf venations on all kinds of leaves
BA02Body Joints – Ball SocketMake a ball and socket joint using two balls of different sizes and a couple of joysticks. Understand how your shoulder joint works, and notice the expansive movements made possible by such a joint.
BA16DIY RespirometerChemical reactions often create a change in colour. Here, we use a classic acid-base indicator to make a simple “respirometer”, which can be used to estimate your metabolic rate as you blow into a solution of slaked lime.PACK OF 6
PL14Law of ReflectionThe Law of Reflection states that the angle of incident light is equal to the angle of the reflected light, with respect to the normal of the surface of reflection, and all three lines are on the same plane.

In this classic experiment, we use pins and a plane mirror to prove this Law.
PL09Light – Umbra PenumbraHave you ever noticed that shadows sometimes have sharp edges and sometimes look blurred? What is the difference and why is this? When a light source is fully blocked out, the shadow is distinctly dark; this is called the Umbra. However, if a light source is only partially obscured, the shadow can look like any shade of grey, thereby giving you a blurry impression; this is called the Penumbra.

In this simple TACtivity, you use household materials to make an experiment where you can observe both these phenomena and make measurements to elucidate your understanding of shadows.
PM15DIY Battery HolderRegular electrical cells available in the market are typically 1.5V. However, several appliances need a larger voltage to work. Even LEDs need a minimum of 1.9V to light up. This requires connecting 2 or more cells in series. To do this in a robust manner, one needs battery holders.

In this TACtivity, you make your own 2-cell battery holder using a foam piece, some metal strips and electrical wire.
PM16DIY SwitchA switch is a mechanism that removes, restores or diverts the conducting path in a circuit when it is operated. In this TACtivity, using ice cream sticks, magnets and some electrical tape and wire, we are going to make a simple tap switch to make or break small DC circuits.
CP05Matter – Electrical ConductivityElectrical conductivity is the measure of the amount of electrical current a material can carry. A conductor is a material which allows current to flow through it easily whereas an insulator is a material which does not allow the flow of current through it.

In this TACtivity, we will set up a circuit using AA cells and an LED, to test the electrical conductivity of different materials used in our daily life.
PM09Magnetic Pen StandMagnets are among the most fascinating things in nature. They are fun to play with, and play an important role in our day-to-day lives. They can attract or repel each other, depending on their orientation.

In this TACtivity, we use a cycle spoke and a CD to make a stand to hang one magnet. The other magnet is fixed on the pen such that it prevents the pen from falling. Adding a colourful fan on top of the pen makes the pen rotate when there is a light breeze from the top or side.

CQ04Measure – LengthLength is one of the fundamental units of measurement. It is often the first thing we are taught how to measure. In this enjoyable TACtivity, using matchsticks, beads and a piece of string, we measure the length/perimeter of regular objects followed by any oddly shaped track/object, e.g. the length of India’s coasts and/or borders. We then compare which methods give the most accurate resultsPACK OF 4PACK OF 10
CQ05Beam Balance ModelMass is one of the fundamental units of measurement. The classic device to measure mass is a beam balance. In this TACtivity, you make your own beam balance – and using nuts (or other items) of known mass – calibrate any unknown masses, such as stones.
CH06DIY ThermometerGenerally, matter of all forms expand and contract, on heating and cooling, respectively. This principle is used in thermometers, where the expansion of liquid mercury helps in determining the temperature. In this TACtivity, we will make and explore a non-mercury-based thermometer, using a test tube filled with propanol and a straw acting as the capillary tube.
PF31Trolley ModelNewton’s Second Law of Motion talks about how the net force acting on a body is directly proportional to the mass of the body and acceleration it experiences.

In this ingenious TACtivity, we use our own Hand Cart to conduct a series of experiments to discover for yourself the relationship between mass and acceleration
PL23Box Pinhole CameraA pinhole camera is a simple camera without a lens but with a tiny aperture. When light passes through this tiny aperture, it projects an upside down image of the object being observed through the aperture. In this TACtivity, we will make a pinhole camera using a chart paper, butter paper, and tape to see lovely inverted images.
PM13DIY CompassThe Earth happens to have its own magnetic field; in other words, it is a giant magnet in itself, because it has a rotating magnetic core. It is one of the reasons life exists on Earth, as the magnetic field provides a protective zone around the Earth preventing dangerous high energy particles penetrating our atmosphere and affecting our cells.

In this TACtivity, we make a compass of our own, using magnets and a template to mount them in, to determine the orientation of the Earth’s magnetic field.

PM03DIY ElectromagnetA current carrying conductor produces a magnetic field, i.e. it becomes an electromagnet. In this TACtivity, we wind enamelled copper wire around a nail and connect the two ends of the wire to a cell. How does the nail start to behave? Can it start to lift iron filings, or does it have an effect on paper/safety pins?
CC23DIY Handmade SoapSaponification is the soap making process, which uses the basic solution lye and different types of fats. The science behind soap making is in the structure of the fats, the properties of the lye, and the chemical reaction that produces cleaning molecules. Not only is it a process that uses science, but it’s also just a fun activity to make your own soap with the features that you want.

BA05DIY StethoscopeA stethoscope is a medical instrument to listen to a patient’s heartbeat or breathing, and typically has a small disc-shaped resonator that is placed against the chest, and two tubes connected to earpieces. Here, we insert pipes in a cut ball and insert binding wire to the pipes to give them the shape of a stethoscope. Foam pieces are fixed at the other end of the rubber pipes to make the ear plugs.
