Group 2 Science Investigatory Project I Title: Potato Battery II Objective: We only need a potato‚ a couple nails and a piece of wire to make a potato battery. It’s a fun science project that helps show the way things work in a battery by using everyday items we see around the house. The goal is to learn more about electricity‚ and possibly a few new science terms along the way. III Materials: * Two Potatoes * Two short pieces of heavy copper wire * Two common galvanized nails

Potato Enzyme Lab INTRODUCTION An enzyme is a protein that speeds up or slows down a specific chemical reaction in an organism. A good rule of thumb is to remember that enzyme names end in “-ase”. This will help in identifying enzymes in further readings. Generally enzymes are catalysts. Hydrogen peroxide is a toxic chemical that is produced in many organisms during metabolism. Organisms must get rid of this toxin to survive. One reaction turns the hydrogen peroxide into water and oxygen. The

pH levels affect Catalase activity in potato samples – (enzymes) Introduction: The aim of this investigation is to understand and monitor the effects pH levels have on catalase activity within controlled potato samples. Catalase is a type of enzyme that is found widespread among organisms that grow in the presence of oxygen (almost all living things) its specific use is to speed up the decomposition of Hydrogen peroxide (H2O2) within cells. Hydrogen peroxide is a bi-product of chemical processes

The potato is a starchy‚ tuberous crop from the perennial Solanum tuberosum of the Solanaceae family (also known as the nightshades). The word may refer to the plant itself as well as the edible tuber. In the region of the Andes‚ there are some other closely related cultivated potato species. Potatoes were introduced outside the Andes region four centuries ago‚ and have become an integral part of much of the world’s cuisine. It is the world’s fourth-largest food crop‚ following rice‚ wheat and maize

Potato Enzyme Lab Enzymes are protein catalysts that speed up chemical reaction in living organisms. The purpose of this lab was to; observe the breakdown of hydrogen peroxide toxin by potato’s enzyme catalase‚ determine factors that influence how quickly the reaction takes place‚ and determine factors that influence how well enzymes function. The first test‚ we were supposed to see what would happen when we add sand in hydrogen peroxide. We filled a test tube with 5mL hydrogen peroxide and we added
Premium Catalysis Catalase Chemical reaction
Potato Catalysis Lab Pre-Lab Assignment Background Information: An enzyme is catalytic protein. It is the most important type of molecule found in living cells. Cells would not be able to function without enzymes. Enzymes speed up or slow down chemical reactions of the cells. It is usually easy to identify the names of enzymes because they end in -ase. The enzyme that acts upon the substrate hydrogen peroxide is usually called catalase. This enzyme is found in both plants and animals

A nuclear weapon is commonly defined as a device‚ which uses a nuclear reaction for destructive means. There are six different types of nuclear bombs. The two main types of nuclear weapons: atom bombs and hydrogen bombs. The hydrogen bomb is the most powerful‚ destructive bomb of all. In this essay I’m going to give a brief history of the hydrogen bomb‚ the chemistry behind the bomb‚ and how much destruction the hydrogen bomb can do. After the Soviet Union’s atomic bomb success during the cold war
