Three Cool Science Fair Projects from 2011 Science Fairs

You can read about cool science fair projects that were used in recent science fairs to get some great ideas for this year.

cool science fair projectsI found myself reading about some cool science project ideas from Google Alerts, as we like to keep track of what is going on in the science fair world, and I found a couple that fit right in with what we teach at 24 hour science projects. The main thing I look for is that if they are quick and easy projects to do, and use common every day things you can find around the house.

One of the things we try to get across is that easy to do does not mean simple science. You can find some advanced science concepts that many people never quite get, but since the projects use things you find at home or a quick trip to the local store, that are easy to organize and do. Some of these can be done is as little asn one day and others take a little more time

Here are summaries of the three cool science fair projects I found from this past season:

  • Looking at mold and different kinds of bread: This is good because there are a variables you could zone in on to study mold. The ingredients are simple as can be, but you will need to do this over a period of days or weeks to keep track of the progress of the mold. Different bread types, temperatures, what you put on it, preservatives are just some of a long list of things you could study.
  • Magnetizing seeds to see if they germinate faster: You can read the details from the link, but this was cool because it came from a grandmothers old wives tail, about magnetizing the seeds they used back on the farm. This is another one that is simple to do, easy to record the data, but will take some time, to watch the germination.
  • Which paper towel is more absorbent: This would be a true 24 hour project because you can almost instantly judge how much water different brands of paper towel really absorb., or if single or double layered or ply make a difference, and even compare it to towels or sponges or whatever you want. Again, there are many variables you can test out with this kind of project, so as an idea starter

Notice that in our minds, these are cool science fair projects because each one of them uses common everyday household items like a stop watch, paper towels, bread, or magnets. Believe it or not you will notice that your kids tend to get more “in” projects when they can go rummaging in your cabinets and closets and find what they need themselves!

When you are dealing with a last minute project, where you don’t have much time you can find some really cool science fair projects that still use the scientific principles teachers require!

Science Projects for Seventh Graders

great science project for kidsWhen looking for a science project for your 7th grade student, it can be a bit difficult  to find the right science project at their grade level. It has to be something they can understand and do mostly for themselves and teach them something. You can help find the perfect 7th grade science project for your student by using some of the resources you have readily at your disposal, including your child’s science teacher, the library, and even resources on the internet.

First, consult with your child’s science teacher when trying to find a good science project idea, especially at the 7th grade level. This way you will know what the class is currently studying to keep the project relevant but not redundant, and clarify any requirements or deadlines that some 7th graders might not quite know how to manage yet.

Next, science project books are easily found at the public library.  These books are reliable and easy to use resources for finding and executing a science project. Trying the library is a great way to teach your child to search for books by subject matter, in this case looking for science projects or the subject matter that interests them, and to ask for help from the librarian if you need it.

Finally, the internet is a great place to find huge amounts of 7th grade science project ideas, but you have to know where to look to save yourself time. While you can begin with a general search for science project ideas, it might be a good idea to search more specifically for websites like that are searchable by subject matter or grade level, so that you aren’t finding projects that are too easy or difficult for your student. Another great tool is the free project guides found at

Eighth Grade Science Projects Ideas

rocket scienceResearching  the right science project for your eighth grader can be a challenge if you don’t know where to look.  But you probably have several useful tools at your disposal to help you find a grade level science project that will interest your student.

First, consult with your child’s teacher or science teacher when searching for the right science fair project for your eighth grader, especially if the science project was assigned through school.  By asking for some ideas from the teacher, you’ll be able to clarify all of the project guidelines and requirements, and be able to find a project that is relevant to your student’s course work.

Secondly, a great place to find good eighth grade science projects would be your local library. At the library you’ll find lots of science project books with helpful project ideas and explanations, all of which are from a reliable source. Additionally, if you need any help finding something suitable for your eighth grader, at a library you can always ask for the help of a librarian to point you in the right direction.

Lastly, the internet is a great way to find eighth grade science projects, but with so much information out there, you have to know where to start. You can do a general search, but it might be wise to be more specific, looking for “8th grade science projects, earth sciences” or “8th grade science projects, physics,” depending on what your student is interested in. You can also find great online guides, often for free, that are loaded with science projects, directions on what materials you’ll need and how to complete them.

Science Fair Project Ideas

If your child just made the announcement to you that they are participating in the yearly science fair at school, you are probably searching for ideas. Below are a few ideas that work well in science fairs, and interesting for both of you.

Pollution is always a popular and fascinating project at science fairs. It also helps children, as well as some adults, understand the real damage that pollution can cause. Some areas that you may want to consider are water pollution, air pollution, soil pollution, and global warming.

If you are looking for something a little more involved, many children love to watch fungus grow. This may sound like a nasty one, but kids think it is amazing.

Electrical projects are always a hit as well. You can do many things under this category, including; using magnets, constructing batteries, building a simple electric or wind generator, and radio waves.

Botany is also a large field with many options. The effects that different elements have on plants is a good option. Do plants grow better in sand, soil, or water? The effects of music on plants, as well as the effect that sun has on plants. With all of the above experiments you can choose one specific plant, or use a variety. Seed germination is also a great project. Botany experiments are well suited for all age groups, and relatively cost friendly.

If you do not see anything that interests you or your child, sit down together and have a brainstorming session. Think of things that are interesting and a little challenging for your child. Your child’s experiment doesn’t have to be one that someone has already done, think outside of the box.

If you’re looking for a ready made experiment, get one of our Science Project guides. They’ll take you step by step through the experiments, all of which follow the scientific method.


Kids Science Projects: or How far will a Trebuchet go?

There are two types of people: those who are absolutely terrified when they hear the phrase “Kids Science Projects” and those who immediately think “Cool!” Let me assure you: I’m firmly lodged in the first category. My husband, an electrical engineer, is in the second category. How do such people end up in marital bliss? God has a sense of humor, and He knew how much we needed each other.

Early in our three kids’ education, we quickly gravitated to a system of sorts. Language arts was all mine, and math and science were all his. (I would like to point out that would include the kids’ science projects, of course.) We overlapped on social studies, and when a foreign language was added to the mix in middle school, I was voted most likely to tutor. Sacre Bleu!

When the third grade science fair rolled around for our oldest son, I made sure my husband got lots of advance notice. Fortunately, he was as intrigued as I was intimidated.

My husband suggested a trebuchet. Although I liked the French sounding word, I was at a loss as to its meaning. According to my American Heritage Dictionary, it’s “A medieval catapult for throwing heavy stones.” The sketch in our dictionary showed a medieval catapult that appeared to be a couple stories high outside a forbidding looking castle. Dwarf-like men were pulling the main levers controlling the spring action. Although such a mammoth creation would certainly have been the talk of our small town, the men in our family made plans for a table top trebuchet that would be practical for throwing small objects without breaking our neighbors’ windows. My husband and son were excited about the prospect of hurling things in our back yard with such a device. If they used a series of objects, they could measure how far the trebuchet could throw said objects and draw their own scientific conclusions.

This project allowed for more father and son bonding time, more trips to Home Depot and more purchased sandpaper than the Boy Scouts’ Annual Pinewood Derby matchbox car competition. Science nerds rock, dude!!

Two years later, our family moved overseas, and it only seemed appropriate that the state-of-the-art, homemade trebuchet should go with us. My husband was a bit disappointed to discover that our local American curriculum-based school didn’t sponsor a science fair for kids. Science projects quickly became a mist in his pleasant memory file. For another 4 years, the trebuchet gathered dust in our garage until one day our ninth grade son had an inspirational moment for his world history project. He dusted off the neglected trebuchet and researched weapons typically used in the Middle Ages. On his appointed day to present, he dressed up as a warrior of that time period and gave a very impressive talk on weaponry of the Middle Ages. His teacher was certainly impressed: he gave our son an A.

You never know where a kid’s science project may take you and your family. It might not be good for two grades in two different countries within six years, but it’s an experience your kid will never forget.

By the way, if you’re in the ‘terrified of projects’ group like I am, grab a copy of 24 Hour Science Projects. The 24 Hour guides have step by step instructions for all sorts of science projects for your kids. It’s almost as good as having an engineer husband with a passion for trebuchets!


Creating an Experiment from a Model, or Demonstration

Elementary and middle school science projects almost always have to be done in the form of an experiment. The trouble for most students is that most of the time, projects that are on the internet or in books are either demonstrations or models. Since they don’t follow the scientific method, neither of these meet the qualifications of the school science fair.

The good news is that many times, a model can be used in an experiment, and variables can be added to a demonstration, so that it can be one, too. Here are five examples of projects that are modified to become an experiment.

– How hot can a solar heater get? – First of all, finding the answer to this question may result in a fire! Make it an experiment by testing two different solar heater models. Construct two identical heaters, one with a glass front, and the other with a plexiglass front. (The instructions are live here.) Measure the temperature over several days, and see which one got the hottest.

– How can you make a potato canon? – This is a fun activity, and it demonstrates how cool science can be, but it doesn’t test anything. How can you turn it into an experiment? Vary the trajectory, and ask, “At which angle will a potato canon launch a potato the farthest?”

– What happens when you mix chalk and lemon juice? – Studying acids and bases is fascinating, but there are no variables – so it’s not an experiment. Change it up. Soak pieces of chalk in water, a basic solution, and an acid, and note the variance in the weight.

– What happens when bean seeds germinate? – This is a great lesson, but what are kids comparing? Turn it into an experiment by testing “At which temperature do bean seeds germinate the best?” Use different watt bulbs to vary the temperature.

– How do bones change when soaked in vinegar? – This is close to an experiment, but the project I saw didn’t have a way to measure the change. The results of a true experiment must be measurable. Come up with a weigh to measure the amount of weight the bones can support before breaking, and you may just win your middle school science fair.

Remember, an experiment is a test of the relationship between two variables that have measurable results that can be replicated. It amazes me that reputable science publications will label any sort of science activity as an experiment. It doesn’t matter that you’re still in middle school type of project isn’t right. You can do better than ‘real’ scientists! Turn a ‘non-experiments’ into middle school projects that will amaze judges, your teachers – and yourself!

The Coolest of our Cool Science Experiments

All of our science experiments are cool, but you’ll have to agree that A Slice of Ice is the coolest of our cool science experiments. You see, A Slice of Ice is an experiment that finds out if the surface area of ice affects its melting time.

Surface area is what’s on the outside. Image you make two cubes out of playdough – measuring 1 inch on each side. There will be six square inches on the outside of the cubes. Then image you flatten one of the cubes, and make it as thin as possible. Way more than six square inches will be on the outside. There is more surface area in a ‘puddle’ of playdough than in a cube.

Now imagine that the playdough is frozen water – a frozen cube and a frozen puddle. Which do you think will melt faster?

That’s what A Slice of Ice will tell you. See what a cool experiment it is?!

The first thing you’ll have to do is make ice of different shapes, but containing the same amount of water. Our experiment guide tells you an easy (and cheap!) way to get ice containers. Then you have to calculate the surface area. Depending on the type of object you have, there are different formula to calculate surface area. Our science project guide has the formula you need built into a spreadsheet. You just measure and plug in the numbers – and it will be calculated for you!

The Most Popular of our Science Project Ideas

Experiments with Vitamin C are among the most popular of our science project ideas. Our Vitamin “C”itrus project is part of the 24 Hour Science Project package. It’s a cool chemistry project that is really impressive, but is really easy to do.

Most ideas for experiments involving chemistry require expensive and hard to find supplies. Experimenting with Vitamin C isn’t like that. In addition to foods containing Vitamin C, you will only need iodine, cornstarch, water, a pot, and a medicine dropper.

First you’ll extract juice from your fruits or vegetables, then you’ll make what is called a ‘titrating’ solution with cornstarch and water – a very easy process. You’ll add the titrating to your juices a drop at a time, and count the number of drops it takes until the solution turns blue. This will indicate how much Vitamin C (did you know it’s really called ascorbic acid?!) is in the juice you are testing. It’s a cool process that is fascinating to watch and do.

You can also use your own ideas to change our experiment up a bit. We give you instructions on how to do that in the expanded version of this experiment in our Middle School Science Project package.

We get notes all the time from kids who have used our Vitamin C science project ideas and have won their science fair.

“I enjoyed doing this experiment with my son. It was very interesting and it turned out real well.
You made it so easy for us. We are so glad we found you website!” – Shannon from Hawaii
