10 Awesome Science Experiments for Middle Schoolers

Easy To Do Science Experiments

Young students are quite inquisitive about the universe, environment and everything in it. The best way to foster a student’s curiosity is through science experiments. Kids learn better by doing things by themselves. If you want your child to ace up his intelligence, then he should experience how science works. The following are the 10 very simple and easy-to-to science experiments for middle schoolers.

WATER FILTRATION-BASIC SCIENCE EXPERIMENT FOR MIDDLE SCHOOLERS     

An easy and simple science experiment for middle schoolers that show how a filter system works. Moreover, this experiment also teaches students to learn science, not just by reading but by performing.

Requirements:

For this experiment, you need a teaspoon, two jars, red food coloring, activated charcoal, and a measuring cup.

Procedure:

  1. Fill the measuring cup with water up to half. Add around 8 drops of food coloring
  2. Divide this mixture equally by pouring half of it in each of the two jars.
  3. Now, add two teaspoons of activated charcoal to one of the jars and cover both of them. 
  4. Leave them in a secluded place for several days.
  5. Note the color of both the jars after an hour, 5 hours, 24 hours and then once a day. Repeat this for three days.

You will notice the difference in the color of water in the two jars. One will be colored and others will be colorless because activated charcoal absorbs impurities from water.
