Students invest countless hours researching, experimenting and creating science fair projects. To maximize results they must select an intriguing topic to focus their research efforts on.
Transformation soda and juice into enjoyable spheres is an eye-catching experiment that students will learn more about surface tension, density and vapor pressure through this eye-catching exercise.
Solar Oven
Use solar energy to make delicious treats like s’mores in this exciting science experiment! Kids will gain insight into the basic principles of the solar oven such as heat transfer and insulation.
To achieve optimal results, students must design solar ovens large enough to hold a dark-colored shallow metallic cooking pan like Granite Ware and use it on an overcast day with little wind.
This project requires adult supervision for cutting cardboard boxes with utility knives and using them. Kids should also be monitored when heating ingredients in solar ovens.
Spherification
Spherification is the process by which any liquid is transformed into gel-like spheres. In this experiment, food is mixed with sodium alginate which reacts with calcium chloride to form small drop-size spheres resembling their original food, such as dark pineapple juice in olive shapes.
This science fair project offers a fun and engaging way to learn about circuits and power. To complete it, copper and zinc electrodes, alligator clips, potato, paper towels and ruler are needed. Ensuring students find STEM topics interesting is vital to their success in STEM courses.
Hand Model
This hands-on engineering project helps students understand the structure of a human hand. It demonstrates how bones, joints and tendons work together to enable fingers to move. The model features straws with notches cut into them to represent joint areas and twine or string as tendons; when pulled on with strings the notches bend like fingers would in real hands.
Kids can explore how a greenhouse affects our planet with this straightforward climate change experiment that’s easy to set up. They can even play music for plants and watch how their growth responds!
Egg Float
Every morning, our backyard chickens lay fresh eggs that we eagerly collect and enjoy their delectable taste. But what happens when there are too many eggs for us to keep track of which are oldest? This fascinating experiment helps uncover that mystery.
This classic science experiment shows how altering the concentration of a solution can influence whether an object sinks or floats, and also introduces children to the differences between salt water and regular tap water.
Though you have seen baking soda and vinegar volcanoes or potato batteries before, don’t recreate these experiments yourself – encourage your child instead to follow his own curiosity in developing knowledge in his own unique way.
Sports Drinks
Sports drinks are designed to help athletes replace water and electrolytes lost during exercise. They typically consist of sugar and salt dissolved in water with added flavorings for increased palatability.
Research indicates that STEM enthusiasts find it easier to select an engaging science fair project idea; however, finding one suitable to their grade level requires both time and effort.
Put this experiment to the test to discover just how much you know about bacteria! All that’s required are some basic supplies and willing participants.
Greenhouse Effect
The greenhouse effect provides one explanation as to why our planet may be warming; gases released when humans burn fossil fuels act like greenhouse glass and heat up the air around us, warming global temperatures. This science fair project tests this theory with an easy model.
Make a catapult out of household items to explore gravity and force. This project makes an excellent science fair project for kids who like building things.
Classification involves being able to recognize similarities and distinctions among groups. This science experiment puts that ability through its paces with an exciting candy classification activity!
Oil on Water
As students enter middle school, their research and experimentation abilities in STEM topics become more efficient. It’s an ideal time for children to explore nature as well as scientific principles applied in real-life situations.
Create glow-in-the-dark sticks, observe how far apart planets are and gain knowledge about greenhouse gases with these easy 7th grade science experiments. Students interested in solar system, fast food nutrition and unexpected chemical reactions will love these experiments!
