The Science For Future

"I can stop looking at porn any time I want to; I stop almost every day. But I can't resist the urge to start again. Am I addicted to porn?" Does this sound like you? Some psychologists think porn can be addicting but many disagree. It's not addictive like a drug can be - I've looked at porn in the past, and I've spent years without porn with no withdrawals. Calling porn tube addictive is an easy explanation that really explains nothing.

As much as there is a place for all insects in the bigger scheme of things, some 'nocturnal' insects can be really annoying to people. Night insects like mosquitoes, moths and the like, buzzes your ears constantly, they bite you, or even takes up residence in your home. Use a box-trap to catch some of these 'nocturnal' insects in the following science experiment:

Invisible ink has been used by spies and secret lovers alike for centuries to transmit hidden messages to their partners. Invisible ink isn't just something you see in James Bond movies; hundreds of liquids, from fruit juices to household liquids, to specially formulated chemicals, can be used as invisible ink. In this science experiment, become a master of 'steganography' by making your own invisible ink from baking soda and send secret messages to your friends:
WHAT YOU NEED:
• Purple grape juice
• Baking soda
• Tap water
• Cotton swab
• White writing paper

At the same time the Egyptians invented the 'shadow clock', other cultures also developed a need to organize their time more efficiently. Amongst others, the Chinese, Greeks and the Romans developed another device for telling the time known as a 'sundial'. Sundials do not necessarily work better than shadow clocks; it is just a slight variation to the shadow clock. Make your own 'sundial' to tell the time in this science experiment:
WHAT YOU NEED:
• Protractor
• Stiff card
• Compass
• Thick cardboard
• Glue
• Scissors

Many electrical devices are used as early warning systems such as burglar alarms, electric fencing systems and many more. Don't you think it will be useful to have an early warning system for rain to warn you to close the windows and bring in the clothes from the clothesline? In the following science experiment you will build a device that can detect rain as soon as the first drops start to fall:
WHAT YOU NEED:
• 9 Volt battery
• Plastic coated copper wire
• 9 Volt buzzer or bell
• Clothes pin
• Effervescent tables
• Wire cutters
• Rubber cement

Microorganisms found in pharmaceutical and healthcare environments require identification in order to determine the species. This is important so that the origin of contamination can be assessed and the origin of contamination determined. This is commonly performed by using a standing technique called the Gram stain, which is based is a type of "phenotypic identification method" and it undertaken so that the microbiologist can understand the general profile for microorganisms.
The first step of most identification schemes is to describe the colony and cellular morphology of the microorganism. Colony morphology is normally described by directly observing growth on agar, where the colony will appear as a particular shape (such as raised, crenated, spherical and so on) and the colony will have a particular pigment. Some microbiologists will attempt to identify the microorganism based on such visual identification.
