Students often struggle to find engaging science fair projects. Instead of opting for projects such as baking soda and vinegar volcanoes or potato batteries, students should search for experiments that spark their curiosity while expanding their understanding.
Water Filtration
Students can design an engaging science project that compares different types of water filters in terms of effectiveness. This experiment also serves to teach children about classification objects through science.
While reviewing makeup, discussing market trends or baking might make for interesting school projects, they don’t count as STEM topics at a science fair. Instead, look for projects that answer a science or engineering-based question.
Gummy bears and other sugary candies float in water, while others sink. This fun experiment demonstrates the principles of osmosis.
Texting Glossary
Finding an engaging STEM topic for seventh graders to research is the cornerstone of success for any project. Unfortunately, however, certain complex scientific areas may take too much time and energy for a student under time constraints to research effectively.
Science fair abstracts should provide an in-depth and succinct description of an experiment and its results, with emphasis on concise writing style, ideally in two or three sentences. They must also include problem statement and hypothesis statements for consideration by judges.
Teach your student about cell reproduction using these hands-on models featuring Oreo cookies and colorful sprinkles. Help her understand the processes of mitosis and meiosis with these easy but effective model kits.
Cellular Mitosis Models
Life science projects for kids offer them an immersive learning experience that covers biology, chemistry, physics and more! Explore ideas here that explore biology, chemistry, physics and beyond!
Kids receive instruction on mitosis and build a model to illustrate it using materials such as string, beads and textured paper. This tactile science fair project also introduces students to meiosis – another similar process used for gamete production – through tactile science fair projects like this one.
Make the most of a rainy day with this water filtration experiment! Explore various solutions and compare performance.
Self-Supporting Wooden Bridge
Students gain knowledge about structural physics as they experiment with designing and building a bridge made from craft sticks. Give students freedom in selecting their preferred design before having them calculate its strength values including its maximum load-bearing capability.
Science fair projects for 7th grade enable students to explore a particular scientific concept using hands-on models. This type of learning proves more efficient than more conventional projects such as baking soda and vinegar volcanoes or potato batteries.
Students participating in this project should draw their truss bridge designs at full scale so they can arrange wooden skewers on them before building begins, saving time. Students can paint their bridges if they wish, making them more realistic or matching the theme of their display.
Biofilm Reduction
Middle school science fairs provide students an ideal platform for them to explore STEM fields that interest them, but projects should not be too complex, particularly since seventh-graders often have limited resources such as lab equipment and time available for projects.
Biofilm, formed when bacteria accumulate on objects submerged in water, can clog hoses, slow water systems or cause illness in people. Students can experiment with ways to decrease this bacterial biofilm build-up using different cleaning solutions or surface treatments on objects being tested.
Caffeine
Some science fair experiments may not be suitable for students. Assigning scores to batteries that last long or testing how well laundry detergent removes stains aren’t scientific; rather, these are more like consumer product tests than proper science experiments.
An effective science fair project begins by selecting an intriguing question for a student to investigate, conducting library and Internet research to formulate a hypothesis, designing an experiment to test it, and then analyzing its results. Prescribed investigations with predetermined outcomes may help students practice formal scientific skills but don’t teach students how to think creatively or problem-solve effectively.
Plant Growth
By seventh grade, students are ready to explore more complex science topics and begin observing how various branches (biology, chemistry, physics and environmental) of science connect. Plant-based experiments provide students an ideal way to explore these connections.
Encourage students to cultivate seeds both in soil and hydroponic environments to compare plant growth between methods. From this data they can compare and contrast results of both forms of planting.
Blowing bubbles may appear frivolous, but when conditions such as temperature are altered it becomes an excellent physics experiment that teaches children about surface tension and density. Other fun experiments include classifying candies into taxonomies to learn taxonomy or turning liquids into spheres using simple recipes with household items.
