Introduction to make science experiments:

Science experiments are fun. They interest the kids very much. An experiment is demonstrative. The observation the primary graders do stay for ever in their mind. They can recall the experiments and answer the questions. Science experiments are much better than theoretical learning. Hence schools are advised to conduct science experiments. The children should be made to take part in it. Science experiments are one way of learning science.

An eggy experiment of science:

An eggy experiment is one way of teaching the children about science.

The experiments requires

(1) a small drinking glass

(2) lemon juice

(3)eggshells

(4) lime stone.

These are inexpensive materials that can be brought by the students to the classroom. Each child can do the experiment by himself and record the observation.

The experiment:

Step 1: Let us ask the children to put the eggshells in the drinking glass.

Step 2: Let us ask them to pour the lemon juice into the drinking glass enough to cover the egg shell.

Step ...
... 3: Let us ask the shildren to observe what happens.

Step 4: Observation shows us that the bubbles come out.

Step 5: What made the bubbles come out?

Step 6: Reasoning : the eggshells contain calcium carbonate. It reacts with the lemon juice and produces carbon dioxide gas. The gas comes out bubbling through the lemon juice.

Step 7: Repeat the experiment with limestone instead of eggshell and note what happens

Step 8: Lime stone contains calcium carbonate and carbon dioxide is released and it comes out bubbling . The little children will remember this experiment and will remember that carbon dioxide is released when calcium carbonate reacts with lemon juice .

Plants need light , air and water to live - an experiment.

We can conduct experiment on plants to see how it survives.

Experiment 1:

The children are asked to keep two pots with plants, one outside the class an the other inside the class. Let the children water both the plants. The plant that is outside the class room grows well. It has fresh yellow flowers. The plant that is inside the classroom sheds its leaves,

The teacher asks the kids "Why is this plant shedding its leaves?

Usually the children come up with varying answers. The teacher then explains that the leaves need the sunlight with which it cooks the food for the plant. Without the sunlight , the plant dies .

Experiment 2 : Now the teacher asks the children to keep the other plant also outside the classroom. She asks the children to water one plant and not to water the other plant. Now she asks the children to observe the two plants the next day. What do they see?

The plant that is watered is alive while the plant that is not watered droops down. This experiment shows that the plant needs water for survival.

Experiment 3 : The teacher locks one pot of plant inside the cupboard and the other flower pot is left outside the class room. After a few hours, the plant inside the cupboard is observed. The plant is not fresh. The leaves droops proving that air is essential for survival. The flower is withered.

These three experiments prove that air, water and sunshine are essential for the survival of plants.
