Christine Peltier Scavenger Hunt

This photo shows an ecosystem. The tall trees and brush represent the producers of the ecosystem. Producers use sunlight and carbon dioxide and a process called photosynthesis to produce oxygen. Hiding in the green are the consumers. Animals like birds, foxes, and fisher cats  live in this ecosystem. In the dirt are worms and bacteria, the decomposers. These organisms not only interact with each other but the non living things in this ecosystem, like the wood pile covered by a tarp. Small animals  can use this to hide and to live in.

These flowers represent producers in the environment. Not only do these pretty flowers produce oxygen through photosynthesis, the produce pollen for bees.

This photo of my Vitamin D supplement represents a compound. Vitamin D is made up of the elements carbon, hydrogen, and oxygen. This compound helps prevent against osteoporosis., arthritis, helps regulate blood pressure and many other things in the body. 

This cereal box represents elements used to fortify food. Calcium, Zinc, Copper and compounds like Vitamin A, C, and D have been added to this cereal to make it more beneficial.

This photo represents how water in a solid form is less dense than water in a liquid form. I found this very interesting to study I Chapter 2 and found that this occurs because of hydrogen bonding. As the water freezes hydrogen bonds with four neighbors form and create a 3D crystal. The molecules of the water are more spread out than in liquid water making the ice float.

An acid is a compound that donates hydrogen ions to solutions. Here, lemon juice represents an everyday acid. On the pH scale, lemon juice has an acidity level of 2. On the other hand, the everyday household cleaner represents a base, or a compound that accepts hydrogen ions and removes them from solution. This household  cleaner would have a lower level on the pH scale.
