1. (10 points) Write out your pre-lab prediction‚ including what evidence or previous knowledge you have to support that prediction. --Answer below: Things "rising" and "setting" give the appearance of something rising or setting. In reality objects like the Sun or Moon aren’t physically rising from the horizon. Most of the motions we see in the sky are caused by the Earth’s motion‚ both its rotation and orbital motion. So all of the "motions" described below are really apparent motions and not

Enzymes Lab Report Inroduction In this lab we explore an enzymes activity and how it can be affected by changes to its environment. An enzyme is a protein and is a catalyst to chemical reactions. It helps accelerate reactions by lowering the activation energy‚ which is needed for reactions in cells to progress at a higher rate. Activation energy is the minimum amount of energy needed for a chemical reaction to occur‚ yielding products from a given set of reactants. (Unit 7: Enzymes lab) Products

Thermodynamics- Enthalpy of Reaction and Hess’s Law December 5‚ 2011 Kylie Case‚ Emma McKee‚ Rebecca Smith Purpose: In this lab‚ the purpose was to verify Hess’s Law. Theory: Four main topics were covered during this experiment including enthalpy of reaction‚ heat of formation‚ Hess’s Law‚ and calorimetry. The first being enthalpy of reaction‚ ΔHrxn‚ which is the heat or enthalpy change for a chemical reaction. The energy change is equal to the amount of heat transferred at a constant

Enzyme Lab Report Introduction: Enzymes are proteins that enable chemical reactions. In the enzyme lab‚ the effects of concentration‚ temperature and pH on the functionality of the enzyme catalase. The enzyme lab was also about measuring reactions by capturing the oxygen that was generated by the reaction. Materials and Methods: Experiment 1‚ 2‚ & 3 Experiment 1 examined the effects of concentration on catalase activity. Experiment 2 examined the effects of concentration in temperature

Sample 1: Play ground sand: khaki colored‚ feels rough‚ has more sand than rocks. Sample 2: Potting soil: black/brown-ish colored‚ feels some what soft‚ has little pieces of bark (woody stem‚ branches‚ and roots of plants.) Sample 3: Backyard soil: Orange-red‚ feels lumpy‚ muddy look alike. What is the texture of each soil sample

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time
