calculate the density of each of your mineral samples. How could you use the densities to identify the minerals?
If the densities are the same, the objects are the same. If the densities aren't same, the objects are different.
Key Concept Would density or color be more useful in identifying a particular mineral? Explain your answer.
I think density is more useful, it is more accurate becuase it will be the same ratio but one mineral can be more than one color.

                       Acid rain is the rain which is acidic and ph of acid rain is 4.3 but clear rain is 5.6 It can be harmful to fish and others wildlife. Plants may die if that area has acid rain. Acid rain will make stone change the shape. Acid rain is very dangerous, plants will die and we won't have oxygen. So we will die later.

Acid Rain

Image result for acid rainAcid rain is any other form of rainfall that is unusually acid, meaning that it has low pH. It can have harmful effects on plants, aquatic animals and basic structure. Acid rain is caused by emissions of sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids. Some governments have made efforts to reduce the release of sulfur dioxide and nitrogen oxide into the atmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes, and sulfur dioxide is produced by volcanic eruptions. The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and weathering of stone buildings and statues.

 This is a tree. It is a producer.
This is a snail. It is The first consumer.
This is a human or Peam. He is the second consumer.

The tree is eaten by snail. And Peam who is the second consumer eats a snail. So, the tree is a consumer, The snail and Peam are consumers. But The snail is the first consumer and Peam is The second consumer.

My group project is finish! My group poster has 1 page with six examples of symbiosis. Their are shark and echeneidae, clown fish and sea anemone, parasite and human, louse and human, bee and flowers, crocodile and plover bird. Shark and echeneidae, clown fish and sea anemone are commensalism. Parasite and human, louse and human are parasitism. Bee and flowers, crocodile and plover bird are mutualism
