Fifth graders apply the concepts they know regarding mass, volume and density in the previous activities to design a boat. Student teams must make a boat which can travel the waters of the Amazon Rainforest. Each group makes a...

Introducing ... the aerogel. The first of a two-installment series teaches young engineers about the properties and uses of aerogels. A PowerPoint presentation provides information about this unique material to help solidify the concept.

Students construct a mockup of a volcano by crumbling up newspapers and piling them into the shape of a volcano. They place a tarp over the newspapers making sure the tarp is large enough to simulate a flat area at the volcano's base....

A bird's life is one of danger and intrigue as it struggles for survival in sometimes harsh environments. To understand how difficult surviving in the wild can be, children play a simulation game where they act as little auks, birds from...

Take your biology class on an exploration of the inner workings of cells with this multimedia presentation. Looking closely at the structure of cell membranes and the processes of osmosis and diffusion, this resource explains for...

The many images and labeled diagrams in this PowerPoint will help learners understand different areas of the endocrine system. The slide show starts with information about the absorption of lipid and protein based hormones, and then...

Microbiology beginners feed different sweetening agents to yeast and measure carbon dioxide production to estimate energy contained in each. They set the trials up in zip-top plastic baggies and then measure gas volume by water...

Young scholars find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped...

Students calculate the area under a curve. In this calculus instructional activity,students calculate the area by integrating the equation. They calculate the volume of cylindrical shapes created between graphs.

Students listen to a portion of Handel's Water Music Suite and hypothesize about what would happen if you tapped on the edge of a glass with varying levels of water. They experiment with the glasses and, in small groups, compose their...

High schoolers observe demonstrations to show factors that affect rates of chemical reactions. In this rates of chemical reactions lesson plan, students investigate how catalysts, reactant concentrations, temperature and surface area...

Students use Internet activities and videos to understand the types of cells, their membranes, and the way that they reproduce. In this cellular biology lesson, students use the Internet to view videos and complete activities. They...

Don't be dense—use a robust resource. The second installment of a five-part Floaters and Sinkers unit has learners determine the densities of several objects. As part of the activity, they learn the displacement method for finding...

I can get more water to stay on a penny than you can! Collaborative pairs determine the volume of liquids that can be contained on the surface of copper pennies and plastic coins. The pairs analyze their results using graphs and go on to...

Sugar isn't good for you, but it's great for yeast! Scholars design an experiment to investigate how variables affect the rate of sugar consumption in yeast. The last installment of a nine-part Life Science unit considers how scientists...

Learners analyze the amount of space required to pack round objects. In this geometry instructional activity, students practice using space economically by practicing packing spheres into beakers. They then translate this concept to...

Students create a ruler for the purpose of measurement using the standard and metric systems. The rulers are of different lengths and are compared to one another. Then students make conversions of different lengths using both systems of...

Test your pupils' understanding of the scale from macro to atomic. While displaying images of different materials, learners identify what they would need to make that material visible. Their choices range from the human eye to an...

Pupils design a fence for a backyard pool. Scholars develop a fence design based on given constraints, determine the amount of material they need, and calculate the cost of the project. 

An outstanding lesson on triangles awaits your math scholars. Learners focus on the triangle, which is the strongest of all polygons. They see the role that triangles play in the design of buildings, and learn about triangle...

In this heat transfer and phase change worksheet, learners experiment with ice, salt, and milk to show the relationship between the temperature of a solution and its phase. Students turn milk from a liquid to a solid and graph the...

Students conduct an experiment about air volume, density, and pressure. In this air lesson, students discuss air, and how it moves. They make predictions about what will happen during the balloon and string experiment. They document the...

Students discover the history of hot air balloons by watching one ascent.  In this physics lesson plan, students utilize a Montgolfier Hot Air Balloon from an earlier lesson plan and record the temperature, rate of ascent and the...

Seventh graders convert measurements in recipes to metric measurements and prepare the food items. They create a metric measurement cookbook.
