6th Grade Science Experiments

Reaching 6th grade is fun because then you become eligible for performing the middle school experiments that may capture your interest a lot. Performing science experiments is not only interesting but it also develops analytical skill that may prove useful in the future when they work on research projects. Students are enthusiastic about performing science experiments because it gives them the opportunity to exhibit their analytical and creative skills.

Science Experiments for 6th Graders

You should go through the laboratory safety guidelines and the procedure for handling the laboratory equipment before starting the science experiments to avoid any mishaps. In 6th grade, students are allowed to handle instruments and samples that are safe, and do not involve any risks. Handling fire or strong chemicals is usually not a part of 6th grade science fair project. Here I come up with some ideas for performing the practical works.

The Egg Experiment
One of the most commonly used substance for 6th grade science experiments. With eggs students can learn rules and laws of science. They can perform a number of practicals, that can include observation of eggs sinking or floating on changing the density of the water, or the difference in composition of hard-boiled eggs and raw eggs. Set up the experiment in different containers. The first containing plain water, the second containing sugar and the third containing salt. Now, dip the eggs in each container and record the results. Try to analyze the results with the help of your teacher. You can also find out the differences between hard-boiled eggs and raw eggs by allowing it to spin.

Evaporation of Water
In this science activity you will determine the rate of evaporation of water under different intensity of lights. You will have to construct several boxes installed with electric bulbs having different wattage. The containers are simultaneously filled with water and the bulbs are lighted. You also need a controlled experiment that will be devoid of bulb. You will notice that the rate of evaporation is highest in the container having maximum power of bulb. This happens because water changes to vapor form more quickly under intense temperature. Since the surrounding temperature of the bulb with highest power is more, so the rate of evaporation is also more.
