Even after half-a-century of Indian Independence, the fate of education, educators and students has hardly improved. The apathy of the power that be, including a large section of society, has not changed when it comes to human resource development and education. Even now there are more than four crore educated unemployed.
Red displays come from Lithium, Rubidium and Strontium. These metals give different intensities in color and some even play other roles. Lithium and Rubidium are metals in group one of the periodic table. Lithium gives a medium red color and is most useful, for this purpose in its carbonate form. Rubidium on the other hand gives a deep red/ violet-red flame and is also used to oxidize the mixtures in these explosives; without oxidation, they will not burn properly. Strontium burns with an intense red but it also has the job of stabilizing the elements used to make the fireworks.
6 to 12 Months: Your baby has much better control over arm and leg movement. By 9 to 10 months, your baby should be able to move around by some means- either pulling, crawling, or scooting. By 12 months they should be able to stand by themselves and many will even start walking. Educational toys including wooden blocks that baby can stack and knock down, throw, or bang together to make noise are good choices. By 12 months, educational wooden blocks can be used for early construction play to promote development of motor skills, cause and effect, sensory and visual stimulation. Educational toys like the Sensory Ball from Edushape, provides great stimulation with different textures. Once babies learn to sit up, they will enjoy rolling a ball and trying to catch it as you roll it back. Letting your baby chase the ball will encourage movement. Trying to figure out why a square block wont go through a round opening will help develop problem solving skills- though it may cause some frustration in the beginning. By the time your baby is 12 months, they will start to enjoy stacking activities, though they will need help in trying to get the right order. More interest in books will be noticeable now. Try to buy books that have pages with different textures and simple flaps. This will help to develop their sense of touch.
Newborn to 3 Months: Babies cannot do much at this stage but their senses are eager for stimulation. Childrens educational toys with high-contrast patterns and bright colors will capture little ones attention. Babies can see color from birth but have difficulty distinguishing between similar tones. Educational toys designed with bright and distinctly different colors like red, green, black and white help babies differentiate shapes and patterns. Babies spend a good deal of time on their backs and sides at this age making colorful mobiles that play music a great educational toy choice. Babies are fascinated by their reflection in safety mirrors. They are not able to recognize themselves but the activity is great visual stimulation. Baby gyms are excellent educational toys because of the variety of stimulation they offer. Baby gyms have bright colors, a variety of attachments with different shapes, textures, and sounds. Most gyms now play music and have lights as well. These educational toy gyms require baby to pull, kick, or bat something to set off the stimulus helping to develop motor skills.
