Middle school science projects approximately always have to be done in the form of an experiment. The problem for most students is that most of the time, projects that are on the internet or in books are whether demonstrations or models. Since they don't consequent the scientific method, neither of these meet the qualifications of the middle 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 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 embark on a potato the farthest?"
- What happens when seeds germinate? - This is a great lesson, but what are kids comparing? Turn it into an experiment by testing "At which temperature do seeds germinate the best?" Use separate watt bulbs to vary the temperature.
- How do bones turn when soaked in vinegar? - This is close to an experiment, but the project I saw didn't have a way to quantum the change. The results of a true experiment must be measurable. Come up with a weigh to quantum the whole of weight the bones can support before breaking, and you may just win your middle school science fair.
- How hot can a solar heater get? - First of all, seeing the write back to this demand may consequent in a fire! Make it an experiment by testing two separate solar heater models. Build two identical heaters, one with a glass front, and the other with a plexiglass front. quantum the temperature over several days, and see which one got the hottest.
- 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. turn it up. Soak pieces of chalk in water, a basic solution, and an acid, and note the variance in the weight.
Remember, an experiment is a test of the relationship in the middle of two variables that have measurable results that can be replicated. It amazes me that reputable science publications will label any sort of science action as an experiment. It doesn't matter that you're still in middle school type of project isn't right. You can do best than 'real' scientists! Turn a 'non-experiments' into middle school projects that will amaze judges, your teachers - and yourself!
