Collaborative earth science groups create a working model of a watershed. Once it has been developed, you come along and introduce a change in land use, impacting the quality of water throughout their watershed. Model making is an...

Here is an excellent cross-curricular lesson. Learners relate multiplication to area by making a grid on graph paper, and then creating the same grid in real space outside in the school yard.

Teams continue with the Asteroid Impact challenge and determine possible locations to construct their underground shelters. Participants cut scale area models of their shelters from paper and place them on the map to find locations...

Students represent volcanoes with models and sketches. They research volcanoes and plan how to build a model. They, in groups, build a model volcano and cause it to erupt making observations before and after the eruption.

The San Andreas fault is one of the longest fault zones in the world. In a series of 20 lessons, the fourth lesson has pupils use a paper model to recreate various types of plate faults. Each is held in position then drawn...

Imagine 28 instructional strategies, appropriate for all subject areas and all grade levels. Directed Reading-Thinking Activities (DRTA), Question-Answer Relationship (QAR) activities, KWL charts, comparison matrixes, classification...

Sometimes it's okay to eat your science experiment. A hands-on activity has pupils create models for algae to learn about its cellular structure. The best part of the experiment? The resulting juice-filled gels are edible—yum!

Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...

They say elephants never forget—and your class won't forget an insightful modeling activity either! Junior zoologists take part in a mock elephant census using the sample count and total count methods. The included materials provide...

With almost half of Americans relying on groundwater supplies, it is more important than ever to protect aquifers from possible contaminants. Working in small groups, young environmentalists explore this problem as they create an aquifer...

Does increasing the pressure between two moving plates provide a stabilizing force or create more destruction? The hands-on lesson encourages exploration of strike-split fault models. The sixth lesson in a 20-part series asks...

Although it appears that this cut-out paper model makes a welcome activity, it is challenging to construct. It displays a square area of a town on a plateau undergoing slump or slope movement. While it is an outstanding model, the time...

Does the early bird really get the worm? If so, which color of worm does it prefer? In an exciting and easy week-long field investigation, young field biologists set up a one square meter feeding area for birds. If you have a webcam,...

Do polar opposites attract? After an introduction on the polarity of molecules, pupils are asked to design a self-assembling model using materials with different polarity. The challenge should motivate learners to develop a workable...

Emerging engineers perform pre-lab calculations in this first of a three-part lesson on model building. They determine the forces of tension and compression in a truss. After completion of the worksheet, pupils will draw a draft of their...

Fifth graders examine the function of the lungs and create a model of the lungs. Using a plastic cup, drinking straw, plastic bag, small balloon, and a rubber band, they follow step-by-step directions to construct simulated lungs. ...

In this area and probability worksheet, students solve 5 problems where they find the probability of an event occurring. They also use a given photograph of the moon's surface to find the area covered by craters and determine the...

Students explore world geography by creating a model in class. In this tectonic plate lesson, students identify diagrams which discuss the tectonic plates in New Zealand and how they affect everyday life. Students utilize cardboard,...

Examine how pollution makes its way into an ocean with help from a model watershed. Scholars use household items to recreate a mini-watershed, equipped with pollutants, that when mixed with rain drain into a model's body of...

Help your class understand the magnitude of the distance between Earth and Mars with an activity that asks small groups to use balloons to create scale models of the Earth, Moon, and Mars. Class members figure out the distances...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

Explore the respiratory system with a model. First, pupils build a set of lungs to experiment how they inflate and deflate. Then, they delve deeper into the topic with a web quest to discover new information about the nose, trachea, and...

Scholars make a model to discover how the force of trade winds over the Pacific Ocean creates an El Niño. Super scientists observe how the severe weather affects life in water and on land. 

Modeling dough and paper cutouts in science class? Learn about how relative age dating concepts, like the Law of Superposition and cross-cutting relationships, can be used to describe the formation of sedimentary layers.
