Make Simple Spectrometer Experiment

Preface Spectrometer is a tool used to measure the spectrum of light, Spectrometer is the basis of other sophisticated equipments such as spectrophotometer, Spectrophotometer is a tool used to measure absorbance by passing light with a certain wavelength on a glass or quartz object called a quvet. Some of the light will be absorbed and…

The Water Cycle Experiment

The water cycle or also known as the hydrological cycle is a state that describes how water moves continuously on Earth. Water cycle through different stages include: Evaporation, Condensation, precipitation and flow. Then go back to the evaporation stage. The whole cycle begins again and hence the name “water cycle”. Stages of the Water Cycle…

Inertial Experiments at Eggs

Preface Inertia or inertia is the tendency of all physical objects to resist changes to the state of motion. Numerically, this is represented by the mass of the object. The principle of inertia is one of the foundations of classical physics used to describe the motion of objects and the effect of force imposed on…

Determining Sugar Levels In Drinks Experiment

Purpose: Determine the levels of beverages that have the highest glucose concentration levels after adding enzymes, invertase the following drinks Coke, Red Bull, Gatorade, Arizona Green Tea, and Sunny D? Hypothesis: Coke will have the highest glucose concentration level because it has the maximum sugar from the rest of the drink so that after the…

Detecting Carbon Dioxide and Water Vapor Experiment

Detecting Carbon Dioxide Experiment

Preface Car exhaust contribute a lot to air pollution. And also contribute to global warming by releasing carbon dioxide and water vapor. Global warming is not from exhaust heat (some contribute) but from the fact that carbon dioxide and water absorb heat from the sun and from heat radiating from the ground. In this experiment…

Fingerprint Detection Experiment

Purpose To detect and obtain fingerprint patterns from our fingers Application Forensic and criminal investigations Basic theory Fingerprints are a unique identity that differs from one person to another. This is a pattern, or trace of the friction region, or lifting the epidermis on the palm of the hand of the finger. The print can…

Made Secret Ink Experiment

Preface Sometimes called security inks, invisible ink or secret ink are substances that can become invisible to the application to the surface, or shortly afterwards. This ink is often used by security and intelligence professionals, to hide messages intended for specific audiences who know how to disclose concealed shipments. Ink Invisible Type Invisible ink can…

Making Elephant Toothpaste Experiment

Making Elephant Toothpaste Experiment

Preface Elephant toothpaste is a term for a very large foam, resembling an elephant’s trunk, or because so many foams are produced so that pas made elephant toothpaste so that his elephant can brush his teeth. Elephant toothpaste experiments show that the hydrogen peroxide decomposition/decomposition reaction can be accelerated with a yeast catalyst. Hydrogen peroxide…

Water droplets form convex lenses that can refract and unite light so that we can see objects clearly and larger, initially the invention of microscopes by early scientists begins in this way that is using small balls that fill with water droplets, with the development of the time then making the microscope is enhanced by the number of lenses that exist in the microscope so that the creation of modern microscopes as it is today

Made Simple Microscope Experiment

Preface Microscopes (Greek: micros = small and scopein = see) is a tool to see objects that are too small to see in the naked eye. A microscope is a tool that can be found almost throughout the laboratory to be able to observe small (microscopic) organisms. Maybe for most students in Indonesia are familiar…

Put two pencils into cardboard, about one inchi apart.

Water Electrolysis Experiment

Preface Electricity can be made when certain chemicals react together. We usually use chemicals to make electricity for example on a flashlight, a clock battery or sometimes a car battery. There are cars that run on electricity! Devices that store electricity are called batteries. Instead electricity can also be used to produce chemical changes or…
