3rd Period - Chemistry-1st Semester - Room 210 - Rajski Assignments

Objective:    
Describe factors that change the Rate of a Reaction
Explain the effects of changing conditions on a reaction at the particle level
Introduction: Chemical reactions are influenced by the conditions of their environment. These components are oftentimes vital to controlling the delicate balance of many existing systems on planet earth. As many ecosystems face challenges such as rising temperatures, acidification, and alternations of nutrient availability, it is important to investigate and identify the driving forces of these changes so that necessary modifications can be made. We have already seen how the ocean is changing and how it is affecting aquatic life such as coral reefs.  In this investigation a chemical reaction will be used as a model to measure how changing conditions can be used to identify drastic shifts occurring in the health of an environmental ecosystem such as the ocean and the many species that live in them.

Watch the video and complete the attached questions.

Objective:
Identify parts of a chemical equation
Explain how changing conditions impact the way that a chemical reaction happens.


There are two ways that we can measure the rate of a chemical reaction
Measure how quickly the reactants are used up.
Measure the rate at which the products are made.

Develop and carry out an investigation that monitors how changing conditions impact vulnerable species.
Identify how characteristics such as concentration or surface area impact the way that a chemical reaction happens.

Objective: Determine how much energy it takes to heat up your home using the formulas.

Objective: Determine how much energy it takes to heat up your home using the formulas.

Objective: Using evidence collected from an investigation - create a mathematical model to show the changes in thermal energy of different materials to identify characteristics useful in maintaining the temperature in our homes. 

Purpose: Keeping your house at a comfortable temperature involves managing the way heat moves around. To do this, we use materials that can either help heat flow easily or stop it from escaping. These materials have different jobs when we're building our houses. When we turn on a heater, we use gas or electricity to change the indoor temperature. The longer these devices run, the more we pay for energy. 

Instructions: Complete the tasks of each part of the analysis using data from your investigation.

Quiz completed on handout in class and passed back.

Directions: Use the concept of thermal conductivity to model and explain your answer to each of the following questions. A key has been provided.

Objective: Create a model that describes the Energy Flow in a system and the relationship between the motion of particles and attraction force

Instructions: Create and explain a model for how a thermometer using fluids functions at the particles level. Use colors and sentence stems to represent what is happening in the two examples.

Use models to illustrate that energy at the macroscopic scale is accounted for by the movement and position of particles.
Investigate the effect of attraction forces on the phases and characteristics of substances.

Heat transfer is the exchange of thermal energy between objects or substances that have different temperatures. Conduction involves the direct transfer of heat through a material without the movement of the material itself. Convection, on the other hand, is the process where heat is transported through the movement of fluids (liquids or gasses). Lastly, radiation is the emission of electromagnetic waves, typically in the form of infrared radiation.

Instructions: Organize your thoughts into complete sentences. Write a reflection using the questions below. You may use as much space as you need.

Objective: Develop macroscopic models that identify and describe the systems and surroundings as well as the matter and energy.

Heat is an important part of our everyday lives, influencing the temperature of our systems and surroundings. In this lab, we will dive into how heat is transferred from one place to another, specifically focusing on three primary modes: conduction, convection, and radiation.
