Frequently asked questions

What is a Science fair? #

Generally elementary school students need to get better awareness and understanding from doing basic science experiments. If it conducted as a event, then it is called science fair. It is really helpful for the kids.

What are good ideas for science fair projects? #

What is the best experiment for a science fair? #

There are so many experiment ideas on our web page and many more to come. The best experiment should be simple and giving better clarity to the science fair audience. You should always select the simple science concept or scientific rules and design the science fair project. Some of the methods to design science fair projects from basic ideas are listed below.

Many More ideas, please visit to our web page.

What makes ice melt fastest? #

The temperature difference is the reason for the melting of ice. If we add some external agents it will melt ice in a faster way. Like sodium, hydroxide salt reacted in the presence of water to liberate heat (exothermic reaction). This liberation of heat makes ice to melt faster.

Ice melting basic information for school students.

How can I win the science fair? #

To win in science fair

You just follow the following info-graphic to win in the science fair.

What is Enzyme? #

Enzymes are proteins. But all proteins are not enzymes. Amino acids are the building blocks for proteins. Enzymes are the bio-molecules, which are responsible for biochemical reaction activity.

What type of reaction is the enzymatic reaction? #

Enzymatic reactions are biocatalytic reactions. Catalysts are responsible for the faster reaction rate. It reduces the activation energy of any particular reaction. That is the reason it undergoes in faster and selective phase.

What are the steps in an enzymatic reaction? #

Four Steps of Enzyme reaction

  • The enzyme and the substrate are in the same area and region. Some special situations have more than one substrate molecules that the enzyme will change physically or chemically.
  • The enzyme binds to the substrate at a special area and region called the active site for the enzymatic reaction. The enzyme acts as a lock and the substrate acts as a key. This is called the Lock-key model.
  • An enzymatic reaction called a catalysis reaction. It accelerates the biochemical reaction and regio-selectivity of the molecule.
  • The enzyme releases the final outcome product in specific regio and stereoselective manner.

How does the concentration of enzyme affect the enzymatic rate? #

Concentration of the enzyme plays very important role in enzymatic reaction. If the concentration of enzyme is high, then more number of enzyme molecules will be there. More number of number of enzyme molecules gives increase in the binding site of substrate molecule. It accelerates the enzymatic reaction.

What are some examples of enzymes? #

Examples of enzymes

  • Lipase is a group of enzymes that help digest fats and fatty acids in the gut.
  • Amylase chemically changes starches into sugars by breaking them into small ones.
  • Maltase is in saliva, which breaks the sugar maltose into glucose in our mouth. The digestion process starts in the presence of saliva.
  • Trypsin is found in the small intestine in our stomach, which breaks big proteins down into amino acids. These amino acids will be the building blocks for protein synthesis in the body.

What is the best science experiment for kids? #

Colour changing experiments are really good for kids. Like, you put different paint colour in the milk solution. Each colour diffuse in different rate as compare with another. You can picture this experiments with different stages. Best science experiments for kids are listed below.

  • Cloud formation experiments in the bottle
  • Volcano experiment
  • Ice melting experiments
  • Crystal growth experiments

How do you make a saltwater experiment? #

Saltwater experiments are very easy experiments to observe the changes in the temperature. Whenever we dissolve the crystals or salt substances in water. It may increase the temperature. In some cases, It may decrease the temperature. It totally depends on the nature of the substance.

If it increases the temperature, then it is exothermic in nature. If the reaction process decreases the temperature, then it is endothermic in nature. You can these experiments with the things available in the kitchen.

Why does salt make an egg float? #

Normally ,if you put egg on the drinking water, it will immerse inside. Because the the density of the egg is higher than the water. When we dissolve the salt in the water. It will increase the density of water. Now if you put the egg on the salt water, it will float in the water.

Because, saltwater density is higher than egg.

How can I make science fun? #

Kids are always eager to learn new things. Science starts from asking questions. As parent and teacher, we should encourage asking questions. “There is no stupid questions. But off course, there is stupid answers.”

While doing simple science experiments and asking questions, it will cultivate the fun of doing science.

How do you teach science in early childhood? #

Science starts from the house kitchen. You can introduce the heat change during cooking the omelettes. How egg white is moving from transparent to hard white? This is happened due to increase in the temperature.

You try to teach the kids learn science with the help of their senses. Our five senses are input for mind, with that it process everything. In our senses, we use seeing and listening most of the time. In science, Seeing or observing played very important role.
