After a wild day of mishaps leaves Clifford wishing he weren't so big, Emily Elizabeth reads Clifford Gulliver's Travels as he drifts off to sleep. He dreams he is a small dog, and is at first excited to be able to do all the things he couldn't before, until Emily Elizabeth needs help. When he wakes up, he is glad to be back to his big, regular size. Join Clifford and explore the fun of comparing all sorts of sizes and colors. In this lesson, students will sort objects into groups by size and color. They will learn how to identify the special attributes of objects and how they can be similar (alike) and what makes them unique (different). This includes five different resources.

This resource from the CIA World Factbook provides a detailed fact sheet of Peru. The content covers the country's geography, people, government, economy, communications, transportation, military, and transnational issues. It includes images of maps and the flag, as well as photos of the country. This resource requires Java.

The Dinosaur Museum is located in Blanding, Utah. Use this site to learn all about the exhibits and dinosaur information.

Economics lesson on economies of scale taught with humor through Seinfeld episode clip [4:03] in which Kramer illustrates the concept and demonstrates the importance of size and scale.

Excellent series of maps from University of Texas at Austin - Provides political and shaded relief maps of France and a multitude of historical maps and maps of overseas territories overseas. Also includes maps of several large cities.

Students are challenged to think as biomedical engineers and brainstorm ways to administer medication to a patient who is unable to swallow. They learn about the advantages and disadvantages of current drug delivery methods—oral, injection, topical, inhalation and suppository—and pharmaceutical design considerations, including toxicity, efficacy, size, solubility/bioavailability and drug release duration. They apply their prior knowledge about human anatomy, the circulatory system, polymers, crystals and stoichiometry to real-world biomedical applications. A Microsoft® PowerPoint® presentation and worksheets are provided. This lesson prepares students for the associated activity in which they create and test large-size drug encapsulation prototypes to provide the desired delayed release and duration timing.

Students' eyes are opened to the value of creative, expressive and succinct visual presentation of data, findings and concepts. Student pairs design, redesign and perform simple experiments to test the differences in thermal conductivity (heat flow) through different media (foil and thin steel). Then students create visual diagrams of their findings that can be understood by anyone with little background on the subject, applying their newly learned art vocabulary and concepts to clearly communicate their results. The principles of visual design include contrast, alignment, repetition and proximity; the elements of visual design include an awareness of the use of lines, color, texture, shape, size, value and space. If students already have data available from other experiments, have them jump right into the diagram creation and critique portions of the activity.

Putting Math to Work

Type of Unit: Problem Solving

Prior Knowledge

Students should be able to:

Solve problems with rational numbers using all four operations.
Write ratios and rates.
Use a rate table to solve problems.
Write and solve proportions.
Use multiple representations (e.g., tables, graphs, and equations) to display data.
Identify the variables in a problem situation (i.e., dependent and independent variables).
Write formulas to show the relationship between two variables, and use these formulas to solve for a problem situation.
Draw and interpret graphs that show the relationship between two variables.
Describe graphs that show proportional relationships, and use these graphs to make predictions.
Interpret word problems, and organize information.
Graph in all quadrants of the coordinate plane.

Lesson Flow

As a class, students use problem-solving steps to work through a problem about lightning. In the next lesson, they use the same problem-solving steps to solve a similar problem about lightning. The lightning problems use both rational numbers and rates. Students then choose a topic for a math project. Next, they solve two problems about gummy bears using the problem-solving steps. They then have 3 days of Gallery problems to test their problem-solving skills solo or with a partner. Encourage students to work on at least one problem individually so they can better prepare for a testing situation. The unit ends with project presentations and a short unit test.

During this two-day lesson, students work with a partner to create and implement a problem-solving plan based on the mathematical concepts of rates, ratios, and proportionality. Students analyze the relationship between different-sized gummy bears to solve problems involving size and price.Key ConceptsThroughout this unit, students are encouraged to apply the mathematical concepts they have learned over the course of this year to new settings. Help students develop and refine these problem-solving skills:Creating a problem solving plan and implementing their plan systematicallyPersevering through challenging problems to find solutionsRecalling prior knowledge and applying that knowledge to new situationsMaking connections between previous learning and real-world problemsCommunicating their approaches with precision and articulating why their strategies and solutions are reasonableCreating efficacy and confidence in solving challenging problems in a real worldGoals and Learning ObjectivesCreate and implement a problem-solving plan.Organize and interpret data presented in a problem situation.Analyze the relationship between two variables.Use ratios.Write and solve proportions.Create rate tables to organize data and make predictions.Use multiple representations—including tables, graphs, and equations—to organize and communicate data.Articulate strategies, thought processes, and approaches to solving a problem, and defend why the solution is reasonable.

This lesson discusses how to determine the appropriate scope for a research question. [11:43] CCSS.ELA-Literacy.CCRA.W.8.

University of Nottingham astronomers talk about telescope diameter, and how the size and quality of a telescope's mirror determine what we see when looking through it. Offers a look at the opportunities offered by the "Extremely Large Telescope", which will be built with a lens over forty meters in diameter. [8:31]

Practice Space Math! Math is the cornerstone of space travel. Familiarize yourself with all the ways math can help you study the solar system. Practice math problems in areas such as speed of light, the distance of planets to the sun, size of the sun, planetary alignments, and travel times by spacecraft. While you are at it, practice conversions and scientific notation. Answer keys are provided.

Using census data, students will create box plots to make inferences about the percentages of people who walk to work in cities of different population sizes (small, medium, and large). Students will use these findings to write a short report.

Start with the questions all students ask: How big is the universe, how far away are the planets and stars, how did they form and when, how do they move and why? Build on their natural curiosity. The Smithsonian, in cooperation with NASA, brings you lesson plans to help students discover answers and questions that can't be answered!

Students learn the value of writing and art in science and engineering. They acquire vocabulary that is appropriate for explaining visual art and learn about visual design principles (contrast, alignment, repetition and proximity) and elements (lines, color, texture, shape, size, value and space) that are helpful when making visual aids. A PowerPoint(TM) presentation heightens students' awareness of the connection between art and engineering in order to improve the presentation of results, findings, concepts, information and prototype designs. Students also learn about the science and engineering research funding process that relies on effective proposal presentations, as well as some thermal conductivity / heat flow basics including the real-world example of a heat sink which prepares them for the associated activity in which they focus on creating diagrams to communicate their own collected experimental data.

Observe the scale of our solar system in this video from NASA. It is difficult to show both the size and distances of the planets on the same model, so this video provides two scale models. A background essay and teaching tips are also included. Closed caption available. [0:53]
