Antocyanins and large variety of similar pigments cause most of the color diversity in plants. Blue, yellow and red colors of flowers, fruits and autmn leaves caused by those pigments. Anthocyanin has the ability to widely change its color depending on acid-base properties, which makes it pretty sensitive natural indicator of pH.
Red cabbage indicator is the purple pigment that can be easily extracted from the red cabbage leaves and used in further experiments to find a pH values of the liquids. Its a neat tool for your science project! Read how to make red cabbage indicator here. Approximately billions of years ago first galaxies were formed. The stars that were formed at that time called the 1st generation stars. Some of them still live, some of them became white or red dwarf stars. Many of them ended their lives as supernovas, producing black holes or neutron stars and fertilizing our galaxy with heavy elements of periodic table, providing matter for the Earth-like planets.
Imagine that carbon, iron, calcium and other heavy elements of our bodies originate from a star that ended as a enormous blast visible from the distance of hundred millions light years. When our Solar System was forming most of this heavy materials were absorbed by the planetoids orbiting the Sun. Planetoids became the planets but some amount of this primordial matter ejected from the old star still exists in form of the asteroids, comets and small particles.
In fact every day tons of this particles collide with Earth and burn in it's thick atmosphere. Occasionally when the piece is big enough - one inch or so - you can see a brief flash of light crossing the night sky. A shooting star. It burns in the atmosphere and almost never reaches the surface. However during descent it disintegrates into smaller pieces. They brake in the atmosphere and slowly fall down as a dust. They called micrometeorites. And this is the star dust we're after. Collecting microscopic pieces of old supernova can be a great 7th grade science fair project! There are 2 main classes of micrometeorites - rock micrometeorites and iron micrometeorites.
It's hard to isolate and distinguish rock micrometeorites from other forms of dust and debris. Iron micrometeorites are easier to collect because you can use a magnet to concentrate them. There are many ways to collect micrometeorites. Seventh Grade Science Projects results. Refine Results. Select a resource. Filter by. Sort by. What Makes Ice Melt Fastest? Science Fair Project Idea.
