Assessment Summary
1. The document discusses using various forms of classroom assessment to improve teaching and learning. It outlines different types of assessments including formative, summative, and assessment for learning.
2. Formative assessments are used to see if students are progressing and if reteaching is needed. Summative assessments check if learning goals have been achieved. Performance assessments and personal communication allow teachers to observe skills and provide feedback.
3. Effective assessments match learning targets and can take various forms including observations, interviews, questionnaires, and products created by students. The document provides tips for conducting interviews and listening to students attentively.
Homework 6 due dec3
This document contains instructions for 4 homework problems related to environmental engineering calculations. Problem 1 asks to calculate the volume of an aeration tank given parameters like flow rate, BOD loading, and MLVSS concentration. Problem 2 asks to calculate hydraulic retention times for continuous flow stirred tank and plug flow reactors treating wastewater. Problem 3 provides data to calculate organic loading rate, F/M ratio, and sludge wasting rate for an activated sludge process. Problem 4 gives specifications for a trickling filter to estimate hydraulic loading rate and effluent BOD.
Chap2
The document contains 3 problems and their solutions related to problem solving techniques. Problem 1 discusses possible explanations for a scenario where two people are found dead in a puddle with broken glass. Problem 2 asks for clarification on the meaning of the question, as the details provided do not seem to make logical sense. Problem 3 provides data to plot a curve and determine the best fit. The solutions discuss setting up matrices to evaluate options, clarifying the problem statement, and using software to plot data and fit curves.
Homework 7 due december 12
This document contains 4 homework problems related to environmental engineering:
1) Calculating the minimum pond volume needed to achieve 80% BOD removal for a 1.0 MGD flow based on given conditions.
2) Estimating the ultimate BOD downstream of a wastewater treatment plant discharge into a receiving stream given effluent BOD, stream flows and BODs.
3) Calculating the soil volume required to cover 6,000 tons of municipal solid waste based on a given waste-to-soil ratio and waste density.
4) Estimating the average moisture content in a municipal solid waste stream based on given composition percentages and moisture contents for different components.
Red Giants And White Dwarfs
Stellar distances are determined by stellar parallax, which is the angular shift of stars caused by changes in the observer's position. Our solar system is part of the Milky Way galaxy, which is approximately 100,000 light years across. The basic physical stellar quantities are luminosity, temperature, chemical composition, size, and mass. A light year is approximately 9.46 x 10^12 km, and a parsec is defined as the distance where a star's parallax is 1 arcsecond, which equals 3.1 x 10^16 m or 206,263 AU. The closest stars to our solar system are Proxima Centauri and Barnard's Star.

Dec 3 haz waste
This document provides an overview of hazardous waste management. It defines hazardous waste and discusses the key US regulations governing its handling - the Resource Conservation and Recovery Act (RCRA) and the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). It also covers hazardous waste sources and health effects, risk assessment procedures, site remediation techniques, and various treatment technologies.
Midterm 1 study guide
The midterm study guide covers various concepts in environmental engineering including acid-base chemistry equations, alkalinity definitions, BOD and reaction kinetics equations, unit conversions, and atomic weights. Sample problems involve calculating pH from acid addition, H2CO3 concentration from pH and HCO3-, and total alkalinity from ion concentrations in well water.
Chap1
This document provides solutions to several problems involving unit conversions in engineering. Problem 1.1A involves converting between units of area, pressure, energy, and force. Problem 1.1B converts an ideal gas constant between different temperature scales. Problem 1.1C determines the correct units for a mass flow rate constant and calculates the new value if SI units are used.
