1. How Much Water is in a Gallon of Water?
Students need some supplies for this classic experiment that helps them learn about liquid measurement physics.
Children will love participating in this creative chemistry project that uses everyday items to explore density.
Students can utilize jars in this fun project from All Science Fair Projects to discover how water filtration works, while also exploring how lighting effects plant growth.
2. How Does Motor Oil Remove Pollutants from Water?
An effective science fair project often requires extensive background research. Students who excel at science fair often enlist help from an experienced mentor in helping them formulate questions, variables, and measurements for their project.
Introduce children to oil and water’s interaction through this classic experiment, while simultaneously teaching them density! You might also try this bridge-building project inspired by Leonardo da Vinci or Linnaeus’ system of taxonomy as additional options.
3. How Does Biofilm Grow?
Science fair projects provide an ideal opportunity for teaching children scientific concepts that may be hard for them to grasp through textbooks, such as biology, chemistry, physics and astronomy. Experiments conducted at science fairs typically encompass numerous scientific areas including biology, chemistry physics and astronomy.
Discover how charcoal powder – commonly found in water filtration systems – purifies water by performing this engaging experiment from Homeschool Scientist. Or try an interesting paper airplane experiment which explores centrifugal force.
4. How Does Helium Affect Our Voice?
7th grade young teens learning the vast branches of science provide them with an opportunity to explore their curiosity and pose new questions, while entering science fairs allows them to narrow down their focus by choosing topics of specific interest to explore.
Example: breathing in a lungful of helium changes the harmonics of our vocal chords while not altering its frequency, as both gases have similar compressibilities.
5. How Can I Make a Lip Balm?
Students can gain knowledge in biology, chemistry and physics with these hands-on experiments. They’ll discover how glow-in-the-dark sticks work as they explore glow sticks for themselves or find out just how far apart planets really are!
Children in seventh grade science fair projects can use this easy experiment using household items to discover whether salt prevents water from freezing. Not only is this project fun for the students involved but it’s a fantastic opportunity for engineering skills development!
6. How Does Biofilm Affect Our Teeth?
You may notice slimy white deposits along the front of your teeth that constitute biofilm, which can lead to gum disease, cavities and other dental health concerns. If this is the case for you, run your finger along their surfaces until a slimy substance appears – that may indicate gum disease, cavities or another issue with dental health is evident.
Students of seventh grade science projects can study photosynthesis, build a volcano and create an exploding Jack-o-lantern with this project. Furthermore, students can do an experiment that explores exothermic reactions or learn about taxonomy through this easy taxonomy study by Linnaeus himself!
7. How Does Sunscreen Affect Our Skin?
Balancing chemical equations and dissecting frogs might not be everyone’s preferred school subjects, but science extends far beyond textbooks and classroom walls.
Students participating in this exciting experiment from All Science Fair Projects maintain three plants under different lighting conditions and compare their growth rates and document the results.
Discover greenhouse gases with this exciting experiment from LiveScience! They can test insulation properties of various materials using an easy setup method.
8. How Does Sugary Drinks Affect Our Teeth?
Sugary drinks have long been considered harmful to both teeth and bodies, but students can explore this topic through an experiment using a straightforward script and basic supplies.
Students can build a bridge out of spaghetti and marshmallows to experiment with force and gravity, engineer a balloon-powered car that tests aerodynamics and physics concepts, or conduct spherification, an engaging chemical reaction experiment.
9. How Does Ultraviolet Light Affect Our Teeth?
Make science come alive for students who find the field dull with these stimulating science experiments! From glow-in-the-dark sticks and Linnaeus’ taxonomy system models, to salt experiments – students will love participating in these enjoyable demonstrations of science’s benefits!
Young teens should take advantage of learning about biology, chemistry, physics, astronomy, and environmental sciences to expand their minds and broaden their horizons. Entering a science fair will provide them with an avenue to narrow down their studies to one area of interest.
10. How Does Salt Affect Our Teeth?
Use just a few materials to conduct an easy seventh grade science experiment that will demonstrate whether salt alters the hardness of teeth. Your students are sure to love this straightforward science experiment!
Step into Linnaeus’ shoes with this engaging taxonomy science fair project! All it requires are unsharpened pencils and loom bands!
Utilizing hands-on experiments to learn about diverse scientific topics is an excellent way for 7th grade young teens to cultivate curiosity and interest in these areas of science – these incredible experiments will definitely do that!
