Students explore gravity, centrifugal force and friction through this hands-on project. The results make an engaging science fair display!
This experiment provides children with an engaging science demonstration about acid-base reactions using simple household supplies and simple assembly.
Use this simple experiment to teach your students about genetics and DNA with just a few supplies required for success.
Model
Seventh graders may begin exploring a wide array of science topics such as biology, chemistry, physics and astronomy for the first time. A model science fair project can help them better grasp these intricate ideas that may otherwise be difficult to visualize without hands-on experiences.
Students can create an egg shell model as part of a physics experiment on elastic and force. Or they could construct a solar oven to learn about how various designs affect energy production from this alternative source of power. Furthermore, using a spherification kit they could explore how liquids take on the form of other objects – or even make their own lip balm!
Interested students in biology can plant seeds or conduct an experiment that explores osmosis’ effects. Furthermore, they could investigate if germs respond differently to different methods of disinfectant by testing how far a paper airplane can travel in this fun engineering experiment.
Research
Research for a science fair project involves reading, gathering information and collecting data. Typically this occurs before conducting an experiment or investigation begins, providing guidance. Furthermore, researching can sometimes spark ideas for cool science fair projects like National Geographic Kids’ dinosaur DNA activity; students can explore genetics while simultaneously sharpening their investigative skills!
Experiments are among the most sought-after projects at science fairs, employing scientific principles to pose questions and test hypotheses posed by students – for instance, whether fertilizer makes plants grow faster.
Demonstration science fair projects demonstrate an established scientific principle, such as the greenhouse effect or gravity, often by recreating an experiment which proves it. Students might build a string phone to demonstrate energy transfer or investigate temperature/chemical reaction rate relationships in this manner.
Experiment
Picking an experiment that suits the interests of your student can help get her engaged with this type of project. When students find something they care deeply about in an experiment, they’re more likely to dedicate the necessary time and effort into researching, conducting experiments, and sharing the results of their efforts with others.
Students interested in computers may enjoy building a robot hand that uses sensors to pick up objects – a fun engineering science fair project they can complete using easily-available materials.
Biological science projects make another excellent choice. Students could use plants to detect chemical contamination in water sources or investigate plant physiology through hands-on experimentation. Students could also explore the relationship between temperature and rate of chemical reaction by conducting this engaging experiment, providing them with insight into chemical kinetics principles.
Presentation
Successful science fair projects require not only extensive research and experiments, but also an eye-catching display board. Selecting an engaging topic will keep your child motivated throughout the process and engaged. Remember to discuss ideas with your teacher as well as any guidelines she gives.
Some science fair projects test a hypothesis while others demonstrate something or even create technology. There are five main categories of projects for science fair: experiments, demonstrations, research models and collections.
An ideal seventh grade science project that teaches children about electrolysis and electroplating requires copper strips and 9V battery snap connectors with alligator clips – both must be supplied for this activity.
