In this math/science worksheet, students will work in pairs to conduct an experiment based on a decay function which is often used to model radioactive decay. Students will shake M & M's in a cup to rub off the M and then record...

Students construct models of microorganisms recognizing size relationships-comparing the size of viruses with the sizes of bacterial and eukaryotic cells. They put into perspective just how small microbes are by comparing the size of...

Students investigate how wildlife management policies affect the size of large animal populations. They develop a spreadsheet that incorporates a mathematical model to predict big game herd sizes, and using worksheet data manage a bison...

Students create their own insect, build a model of it and explain its life cycle.

Students practice adding polynomials using algebra tiles. Students view a PowerPoint presentation in which they are introduced to the concept of modeling polynomials using a scaled down version of algebra tiles. Students walk through...

In this compounds instructional activity, students are given a bag of colored gumdrops that represent specific atoms. They construct ionic and covalent bonds with gumdrops using the key provided and the compounds to build. They fill in a...

Twelfth graders build a replica of the Roman aqueduct. In this Roman engineering lesson students create and label a model of the Roman aqueduct. Students watch a slide-show of the Roman aqueduct ruins.

Students model a food web and create a miniature ecosystem. In this animal interactions lesson, students engage in a role playing game which simulates a food web. Students then build miniature ecosystems using pop bottles, snails, plants...

Students explore early hominid evolution as they analyze bones that share characteristics of both apes and humans. Students compare and contrast key skeletal differences between chimpanzees and humans. In groups, they sort and group a...

Students compare and contrast key skeletal differences between chimpanzees and humans: brain size, teeth, hand and thumb, trunk, pelvis, lower limb, foot and big toe. They then sort and group a set of mixed "fossil bones" of chimpanzee...

Students examine how hormones affect different tissues. In groups, they make their own hormone-receptor model and identify the characteristics of tissues that respond to the different hormones. To end the lesson, they examine the role...

Twelfth graders solve problems using differential equations.  In this Calculus lesson, 12th graders analyze data regarding the spread of a flu virus.  Students use the symbolic capacity of the TI-89 to develop a model and...

Learners create factor trees.  In this prime and composite lesson, students model fractions using tiles.  They create factor trees and identify prime and composite numbers.  Learners use grid paper and tiles to model...

Students access a variety of Egyptian Culture and pyramid related resources on the Internet. They explore various websites, read articles, create an Egyptian art figure, construct a model of a pyramid, and describe the mummification...

Fourth graders study the names and parts of the excretory system in this hands-on activity. They use common items to make a model of the system.

Students investigate the reason for seasons on Earth during three activities. They construct a model of the Earth and Sun to identify patterns in the changes of the angle of light on the Earth's surface. Then they conduct a heat...

Students use models and symbols to represent properties of the Pythagorean Theorem. In this right triangle lesson, students connect real jobs to properties of right triangles. They solve word problems applying the correct ratios and...

In this algebra worksheet, students solve rational equations and inequalities. They model word problems using equations and find the minimum amount as it relates to an inequality set up. There is an answer key for this problem.

Fifth graders examine and participate in the process of classifying rocks. In small groups, they sort the rocks into two categories and complete a Venn diagram. Next, they select three rocks, and complete a worksheet that is in the...

Students describe the structure of atoms, including the particles that make them up. They recognize that key scientists and experiments have contributed to the changes in the Atomic Theory.

Students explore the value of currency and how to save and earn interest. In a key lesson, kids even get to purchase items in their classroom's general store. It's a fun way to learn the importance of being financially literate!

Students design a tomb, create a model of it, and complete a short written assignment explaining the design and contents of the tomb. They study the concept of the afterlife and the importance of pleasing the gods and goddesses.

Young scholars explore the concept of air pressure. Using candy or cookie wafers to model how air pressure changes with altitude, they conduct an aluminum can crushing experiment, compare the magnitude to gravitational force per unit...

Fifth graders explore the concepts of range, median, mode, and mean through the use of graphs drawn from models. They use manipulatives to represent data they have collected within their groups, and compare the differences between mode,...
