In this activity (located on page 4 of PDF), learners gain insight into the actual size of dinosaurs and practice making estimations and measurements. Learners measure the lengths of various dinosaurs by measuring lengths of string in field or gym. Learners also estimate and measure these lengths by lying head to foot. Learners also compare and contrast the sizes of different dinosaur species. Less

Students determine the coefficient of restitution (or the elasticity) for super balls. Working in pairs, they drop balls from a meter height and determine how high they bounce. They measure, record and repeat the process to gather data to calculate average bounce heights and coefficients of elasticity. Then they extrapolate to determine the height the ball would bounce if dropped from much higher heights. Less

In this math activity, learners pretend there is a special store that lets you pay for toys by their weight in pennies. Learners estimate how much toys would weigh in pennies and then use a scale to calculate the prices. This activity guide contains a material list, sample questions to ask, literary connections, extensions, and alignment to local and national standards. <br> <br> Note: If you don't have a balance scale, you can build your own by taping a paper cup to each end of a clothes hanger.

How to Estimate the Value of Pi

This lesson is about the estimation of the value of Pi. Based on previous knowledge, the students try to estimate Pi value using different methods, such as: direct physical measurements; a geometric probability model; and computer technology. This lesson is designed to stimulate the learning interests of students, to enrich their experience of solving practical problems, and to develop their critical thinking ability. To understand this lesson, students should have some mathematic knowledge about circles, coordinate systems, and geometric probability. They may also need to know something about Excel. To estimate Pi value by direct physical measurements, the students can use any round or cylindrical shaped objects around them, such as round cups or water bottles. When estimating Pi value by a geometric probability model, a dartboard and darts should be prepared before the class. You can also use other games to substitute the dart throwing game. For example, you can throw marbles to the target drawn on the floor. This lesson is about 45-50 minutes. If the students know little about Excel, the teacher may need one more lesson to explain and demonstrate how to use the computer to estimate Pi value. Downloadable from the website is a video demonstration about how to use Excel for estimating Pi. Less

Through this nutrition activity (page 5 of the PDF), learners will understandäóîand probably be surprised byäóîhow big serving sizes of various foods should be. This is accomplished in a very interesting way: learners will practice estimating by comparing various foods to everyday objects, like a hockey puck and a computer mouse. This activity was created as a pre-visit for a traveling science show, but makes a great stand-alone activity as well! It is an excellent visual representation for learners to remember. Less

Introduction to Estimation Theory

This module introduces estimation theory and its terminology, including bias, consistency, and efficiency. In searching for methods of extracting information from noisy observations, this chapter describes estimation theory, which has the goal of extracting from noise-corrupted observations the values of disturbance parameters (noise variance, for example), signal parameters (amplitude or propagation direction), or signal waveforms. Estimation theory assumes that the observations contain an information-bearing quantity, thereby tacitly assuming that detection-based preprocessing has been performed (in other words, do I have something in the observations worth estimating?). Conversely, detection theory often requires estimation of unknown parameters: Signal presence is assumed, parameter estimates are incorporated into the detection statistic, and consistency of observations and assumptions tested. Consequently, detection and estimation theory form a symbiotic relationship, each requiring the other to yield high-quality signal processing algorithms. Less

In this math lesson, learners practice estimation and measurement skills as they move from station to station calculating length, volume, weight, and area. At each station, learners first estimate, measure, and then compute the difference between their estimation and the actual measurement. They estimate and measure marbles to the nearest gram and squeeze water-saturated sponges to practice measuring in millimeters. Learners practice linear measurement estimation skills by throwing cotton balls and rolling toy cars. Learners determine if they are a square or a rectangle by measuring and comparing arm span and height. Finally, each learner determines the area of his/her foot by counting and computing the area by constructing a rectangle to approximate the area. Less

In this math lesson, learners apply measurement skills to determine, in dollar bills, the capacity of a suitcase. In a fictional scenario, the prize for winning a radio contest will provide the winner with up to $1,000,000 in cash. The catch is that the winner is only allowed one suitcase in which to carry away as much money as it will hold. Will this amount be more or less than the $1,000,000? Learners devise plans to determine an appropriate estimate for the amount of money it will take to fill a given suitcase. Less
