Science Fair Projects for 4th Graders

The 4th graders are students between 9-10 years of age. These kids have little knowledge of the different scientific concepts. Although they are able to understand few basic concepts however, need help in doing something like a science fair project. The science fair projects for 4th graders should be based on simple concepts that are easy-to-understand. Let us find out more about such projects.

Interesting Science Projects for 4th Grade Students

The 4th grade science fair project ideas given below are easy to experiment with. It is possible to demonstrate few of the fundamental concepts of science through projects described below.

Creating a Magnetic Compass: The project of creating a magnetic compass is very simple to execute. For this 4th grade science project, one would require following items: a needle, cork, bar magnet and small bowl of magnet. In this experiment, one has to first charge the needle by rubbing it against the bar magnet. The needle should be rubbed repeatedly for about 15-20 times. One should keep in mind that needle has to be rubbed only in one direction. Once, the needle gets charged, it should be driven through the cork and placed in the water bowl. As the water becomes still, one would observe that needle automatically attains a north-south direction. This happen due to the magnetic charge acquired by the needle.

Making an Electromagnet: Procedure to create an electromagnet is quite simple. The resulting effect which can be observed is quite fascinating. 4th graders can be introduced to the concept of electromagnetism through this experiment. To carry out the project of creating an electromagnet, one would require a copper wire, iron core, battery and other iron objects (for example, safety pin). Copper wire should be wound around the iron core tightly in a spiral manner. One should see that every successive loop is as close as possible to the previous one. Once the winding activity is completed, ends of the copper wire should be kept ready for passage of electric current. One end of the wire should be connected to the positive terminal of battery and other to the negative. As current passes through the copper wire, magnetic field is created which attracts iron objects; the phenomenon is known as electromagnetism.

Apart from the above mentioned ideas for science fair projects for 4th garders, one should also try out the following science activities for kids.

• The following project idea on the topic of magnetism should be an interesting one. In this project one has to determine whether magnetism travels through all materials. Putting different materials between a magnet and noting down the results should be the main task in this project. The results of this experiment provides information about which materials are affected by magnetic field and one also gets to know the intensity of magnetism for different materials.
• There is one more simple project which can be performed by 4th graders. The experiment to find out preference of cockroaches for a direction can be interesting, just like the one mentioned above. For this project, one will have to catch a cockroach and release it to find its direction preference. The activity should be performed repeatedly in order to establish trends and patterns regarding the cockroach's direction preference. The same experiment can be performed with other insects (for example, ants).
• A project on seed germination should be helpful in teaching kids about this natural phenomenon. The topic for this project should be about checking whether seeds germinate in liquids other than water. To perform this experiment, different liquids such as juice, milk, vinegar, etc. should be used.

The science fair projects presented in the article are fairly simple to understand and make use of fundamental concepts. Parents need to help these 4th graders to carry out the project work in a safe manner.
