4th Grade Science Projects

science fair projects If you are stuck for ideas for this year’s 4th grade science project look no further.  We have lots of fun and easy 4th grade science projects for you to do here at Raising Sparks.  All of our science projects for the 4th Grade are easy to do and all of our science experiments can be performed at home using basic household items.  Prepare to be amazed and raise a few sparks! (See bottom of page for guidance on carrying out 4th Grade Science Fair Projects.)

Or why don’t you check out this Super Science Fair Projects Step-By-Step guide.

floating egg experiment 150x150 Floating Eggs Experiment

Why don’t you sink in the Dead Sea?  More liquid density fun.  How can you make an egg float?  Experiment with solutions and learn more about density.

Don’t forget to use the scientific method in your 4th grade science projects. Here are the steps in case you need a reminder!

Start With A Question: All good 4th grade science projects start with a question, we’ve given you lots of examples above.  Your question might be about something ordinary that you come across everyday such as ‘How do air bubbles get inside the bread on my sandwiches?’ or it might be something you have read about or seen on TV such as The Dead Sea.

Research: What is already known (or at least supposed) about your question.  Use the library and the internet to do research around your question.  Do teachers, parents or your friends think they have any answers?  They could be wrong, but it will help you form a hypothesis.

Hypothesis: Use your research to help you formulate a hypothesis.  Jot down a brief sentence describing what you think might be the answer to your question.

Experiment: Think of a way to test your hypothesis, again we’ve given you lots of great ideas for experiments here.  Is your test a ‘fair test’?  Sometimes experiments don’t always give the same results when repeated.  This is because of ‘variables’, other factors which might affect the outcome of your experiment.  Try to do several ‘controlled’ experiments never allowing more than one variable to change at a time.

Data: Find a suitable way to collect and record your findings.  What do you need to measure your results? We always advise keeping post-it notes handy to jot things down during experiments.  You can also take photographs and make videos.  Charts and graphs might be useful.

Observations: Make some detailed notes.  Did anything happen that surprised you?  Did the intended experiment ‘go wrong’?  What did you learn from this?  What factors may have affected your results?  Do you now have more questions?  Are further experiments required?

Conclusions: Did the experiment support your hypothesis or not?  Can you answer your original question?

Present Your 4th Grade Science Project: Hopefully all the work you’ve done will leave you with lots of notes, pictures and graphs.  Now you need to present this information to your audience in a manner that is relevant, clear and precise.  Make a book or a powerpoint presentation, design a poster with graphs and diagrams, or write up a good old fashioned report!
