Flowers Used for Dye Hollyhocks Hollyhock‚ or Alcea rosea‚ petals are available in varying shades from nearly white to almost black. The dyes made from these petals range in color from bright green to greenish brown depending upon how the blossoms are prepared. According to Rakhi Shanker and Padma S. Vankar from the Facility for Ecological and Analytical Testing in Kanpur‚ India‚ a substance such as alum or other metal salts is used to make the dye stay on the fabric without quickly washing out.

Science Investigatory Project I. Problem Most people have a hard time figuring out what kind of soaps and solutions would be best for their skin and they want it to be very inexpensive. So we decided to plan on making such bath time bubbles for people who consider very healthy body washes. II. Title Herbal Skin Rubs III. Rationale Most people suffer from skin pigmentation‚ uneven skin tone‚ dry skin‚ etc. Most things that women worry about. This one would be best for them to try.

Chapter II REVIEW OF RELATED STUDIES AND LITERATURE Related Literature It is said that Lemon Grass is an excellent insect repellant. The ancients were familiar with this attribute. This action‚ bug repelling‚ does not carry the same punch that it did in the days of the Israelites. Egypt was fertile because it had good soil and lots of water. An abundance of water meant lots of insects‚ specifically mosquitoes. Mosquitoes carry malaria‚ which was bad news in the ancient world. The ancients

The researchers have picked the safest and easiest procedure and materials in making a solar cooker so that teenagers or even people younger may try making it themselves. The first step in making the solar cooker was finding the right materials. This included a long narrow box‚ poster board‚ a roll of foil‚ Popsicle sticks‚ cardboard and barbecue sticks. Since the focal point needed to be somewhere

occurs in materials which have a relative permeability less than one. The result is that is eddy currents are induced in a diamagnetic material‚ it will repel magnetic flux. • The Meissner Effect: occurs in superconductors. Superconductors have zero internal resistance. As such induced currents tend to persist‚ and as a result the magnetic field they cause will persist as well. • Oscillation: when an A current is passed through an electromagnet‚ it behaves like a diamagnetic material. • Rotation:

CHAPTER I INTRODUCTION BACKGROUND OF THE STUDY In our world today‚ purified water is the one that most of the people drink everyday especially those who live in cities. Water purification is the process of removing undesirable chemicals‚ biological contaminants‚ suspended solids and gases from contaminated water. The goal is to produce water fit for a specific purpose. Most water is purified for human consumption (drinking water)‚ but water purification may also be designed for a variety of other

------------------------------------------------- Geography of Antarctica The geography of Antarctica is dominated by its south polar location and‚ thus‚ by ice. The Antarctic continent‚ located in the Earth’ssouthern hemisphere‚ is centered asymmetrically around the South Pole and largely south of the Antarctic Circle. It is surrounded by the southern waters of the World Ocean – alternatively (depending on source)‚ it is washed by the Southern (or Antarctic) Ocean or the southernPacific‚ Atlantic
