The spot you are standing in right now—how did it look 2,000 years ago, one million years ago, or even four billion years ago? Scholars use a model of Earth throughout history to learn about continental drift, climate change, changes in...

Americans spend around one billion dollars each year on school uniforms, but are they necessary? As pupils research the debate topic, they form their own opinions. They review the history of school uniforms and discover the top pro and...

With billions of options to choose from, how can people determine which online sources are reliable? Using an informative resource, pupils first discuss and evaluate a sample search result handout. Next, partners create a checklist for...

Begin your next class with a BANG! Pupils discuss the formation of our universe and its expansion before proceeding with an activity designed to demonstrate what most likely occurred billions of years ago. They conclude with a discussion...

This resource provides an explanation of NASA's GALEX mission and how the space-based telescope can view distant galaxies as they were billions of years ago. The resource also discusses the other aspects of galaxies that GALEX...

How much is a million? This unit has a set of lessons investigating large numbers on the order of millions and billions. A culminating project has groups creating a slideshow and poster about large numbers found in the school and/or...

Students examine how to calculate the part-per-million and part-per-billion units used to measure contaminant concentrations in the environment. They calculate ratios, take a quiz, analyze a sample chemical spill, and determine if...

Students develop a sense of the scale of our solar system by creating a one to ten billion scale model. They calculate the relative sizes and distances for the planets and asteroid belt using a guiding worksheet. To create the model they...

Students perform an experiment in which they will use a statistical method called `sampling' to count to a billion (and beyond). Students practice sampling by estimating the number of characters on a page from the classified section of a...

Fifth graders write numbers in standard and expanded form.  In this writing numbers in standard and expanded form lesson, 5th graders write integers up to billions in word form and standard form.  Students use number cards to...

Students practice dating fossils. They learn the concept of "deep time"--that earth was formed billions of years ago. They experience excellent hand-outs and virtual age tutorial links.

Students view NASA images of galaxies and develop a galaxy classification scheme. They compare and contrast their classification scheme with that developed by Edwin Hubble. They recognize that galaxies are collections of billions of stars.

Students use this activity to establish a new mode of reference to the conceptualization of time. To present hominid evolution in terms of millions of years and endosymbiosis of eukaryotes in billions of years carries little meaning to...

Students create a large (classroom-sized) timeline showing the history of life on Earth for the last 5 billion years. They are able to identify the events that are relevant to their taxonomic projects (the Origins and important...

Young scholars share ideas about keeping things safe, then read a news article about a huge vault built to store billions of seeds. In this current events lesson, the teacher introduces the article with a discussion and vocabulary...

Students in technology classrooms review how microprocessors work, examine Moore's Law, and relate it to the predicted end that is in sight for silicon dioxide-based transistors used in billions of chips.

Learners calculate percent change and create lists of data. They enter the corresponding bushels of corn measured in billions to their list and display, then convert the acres into scientific notation and use the value on the home screen...

Students create a portrait representing Ramadan with the phases of the moon. They are told that more than 1 billion people in the world, from various countries and walks of life, are Muslim. Students use a lunar claendar to determine the...

Students read a book about Matthew Martin who wants a new computer program. He has no savings, and he's in debt to most of his classmates and his parents. His parents share their experiences of buying on credit and getting out of debt.

Students consider the definition of an ecosystem, its parts, and how these parts can be affected when the ecosystem is endangered. They examine dangers being faced by the Canadian boreal forest by reading "For Billions of Birds, an...

In this math worksheet, students analyze two lists of number words to spell. The numbers on the lists range from one to a billion.

Students ask questions about the nature of science as they experience a 'Fossil Hunt'. They reconstruct a book that has been literally destroyed, just as the fossil record has been changed by billions of years of geological processes.

Expand on prior knowledge of place value to teach your class how to round whole numbers. This essential skill is explained with the help of a number line before introducing the explicit rules for rounding numbers up and down. Work...

Young scholars label a chart that includes place value periods (units, thousands, millions, billions), places, and examples of each place value in powers of ten. They then show knowledge of how place value relates to power of ten by...
