5 Benefits of Science Experiments at Elementary School:

Learning science has many benefits

You may think that elementary-aged children will make a mess, may not fully understand, or simply cannot handle a science experiment. However, this is not the case. Children at a young age comprehend a lot more than you think, and there are many positive benefits to doing science experiments starting in elementary school. I will tell you about a few of the benefits below.

1. Children tend to do best when they are actively involved in the learning

Children need to be able to ask questions, participate in interesting discussions, and tell you about their interests. When they are actively involved in learning, their brains are grasping so much more information than when not.

Concentration is very important during science experiments

2. Children’s senses should be stimulated

The five senses are smell, hear, taste, feel, and see. Therefore, children need to stimulate these senses to learn. Science experiments are great ways to engage all five senses!

Experiments improve kid's senses

3. Hands-on activities are best for young children

Most children do not learn only by seeing; they learn by doing. By being able to actually do the activity, they are able to fully observe what is happening, ask you questions, and experiment to see what will occur.

Hands-on activity is useful for kid's brains

4. Young students should be allowed to be curious and discover science themselves

It is important for young students to be allowed to let their curiosity soar and make discoveries themselves. If they discover something themselves, they are more likely to remember it.

Let your kids be curious

5. Critical thinking skills are developed when students participate in science experiments

Critical thinking skills are important in everyone’s lives. That is why you should encourage young children to develop critical thinking skills. Science experiments are an excellent way to do this because the children are able to ask you questions as well as find the answer to the questions that they had for themselves.

To see an up-close look at 10 science projects for elementary school students, watch LAB 360’s YouTube video. The video shows how to carry out each science project which will benefit you in knowing exactly how to do them.

If you have heard the term Special Day School teacher or SDS teacher and would like to know more about what that is, I recommend checking out my other article on this subject by clicking here. A SDS teacher is very important in the classroom and one of the best parts about their job may be to bring fun-filled activities for the students to participate in such as science experiments and hands-on learning experiences.

Safety Measures for Elementary School Students:

It is crucial to have certain safety measures in place when doing science experiments with elementary school students. Everyone can experience an accident when doing an experiment, but young children are more prone to accidents than other groups. This does not mean that you should not do science experiments with this age group; it just means that you should take extra precautions. You can even make the safety measures a routine with your students, which will ensure that they always know what to do to prepare for their upcoming science experiment.

Don't forget about safety rules

The following are safety measures for elementary school students participating in science experiments:

  1.  Put on your goggles, coat, and gloves .Your students should have their own sets of goggles, coats, and gloves. These items should be put on before beginning the science experiment to ensure protection. Make sure that everything fits each child perfectly.
  2.  As the teacher, be sure to check chemicals in the science experiment before allowing the children to participate A lot of experiments do call for household chemicals. Make sure that you read all labels to the products that you are planning to use beforehand. Ensure that there are no hazards and be sure to tell the students not to put any chemicals near their mouth or eyes. Properly dispose of all chemicals after you are done using.
  3. Be sure to keep sharp tools out of reach and help the children if they must use them Try your best not to use any glass. Cuts tend to be the most common injury when doing science experiments with elementary students. If a child must use scissors, make sure you help them or do the cutting yourself. Pre-cutting everything will eliminate the risks.
  4. Be careful when using plants in an experimentYou will need to watch children closely while they are handling seeds. The reason for this is to ensure that they do not put them in their mouths. You will also need to make sure that they wash their hands after dealing with plants or seeds. This is important because plants and seeds are sprayed with fertilizers and insecticides. Please do research on the type of plant that you are using because there are many different types of plants that can cause sicknesses.
  5. Be cautious when bringing animals into your classroom for an experimentA lot of young children do not know how to properly handle live animals, so you need to make sure to give a lesson on how to handle the animal or creature with care during the experiment. If a child does not want to touch the animal, that should be their choice. I do not recommend forcing a child to touch an animal. If they choose to participate, you should supervise closely. It is important to make sure animals are not mistreated or mishandled. In addition, do not bring wild animals into your classroom because they can have diseases that are dangerous to humans.
  6. Make sure that heating materials are not used by children to prevent burnsAnything that is hot should not be used by children. This includes hot water. If a cup is filled with hot water, do not let the student hold it. It can easily break or spill. It is best if only you handle the hot items.
  7.  Anything that is broken or spilled should be cleaned up right awayIt is OK if something gets broken or spilled. Make sure that the students move away from the area and do not touch. Everything will need to be cleaned up before they can go back to doing their experiment.
  8. Create an emergency plan for when things go wrong and go over this with studentsYou never know how a science experiment is going to go. It is wise to create an emergency plan and go over it with your students beforehand. This will help them know what to do when you say it is time to do the emergency plan. You will need an emergency plan in case any of the following accidents occur: burning, poisoning, allergic reactions, first-aid accident, fire, spill, animal bite, etc.

Even if you are teaching remotely, there are science experiments that can be done in the comfort of your student’s home. Take a look at LAB 360’s other video showing you the experiments that little one’s will enjoy doing at home.

During a science experiment, children may get loud and rowdy because they are excited. Every student must be able to hear you to ensure that they are being safe while participating in the science experiment. Therefore, my advice is to purchase a voice amplifier for these specific activities. These devices will make your voice loud and clear, so that each student can hear you and comprehend everything you are saying at all times.

Useful Resources


I hope this article helped you come up with several fun science experiments for elementary school. No matter the age of the child, there are always ways to get them involved with learning about science. All teachers should put away the books and worksheets from time to time and do some science experiments to get your students motivated, alert, and learning. I guarantee that they will also be smiling and laughing while doing these hands-on experiments, which is a win-win for you! Good luck and happy experimenting!

    • My favorite? There are so many to choose from. But I’ll go with a really simple one that I absolutely love:
      You take 6 test tubes and put the same amount of vinegar in each. Into 6 identical balloons, you add six increasing amounts of baking soda. You put the balloons on the test tubes and then predict what will happen when they are all flipped up.
      Prediction? The balloons will get progressively bigger.
      Reality? The last three balloons are the same size.
      Blows. Kids’. Minds.
