Third graders participate in a game in order to review geometric concepts.

Students study the effects of shielding on the amount of detectable radioactivity from a gamma source. They investigate the shielding of one type of metal, then design their own experiments to answer questions raised during the...

Students discover the types of stress that materials undergo. They examine how bridges and skyscrapers are built to withhold the tension. They create their own structure out of marshmallows and spaghetti.

Learners find out the meaning for prefixes used in math vocabulary. By dissecting words used in everyday math, they figure out what the prefix indicates and what the word means. A variety of well-organized worksheets and activities...

If you are just starting out as a teacher for children with visual impairments and want a fun way to teach braille and phonemic awareness, look no further. You'll fill 21 boxes with objects that start with specific letter sounds. You'll...

Help learners use a variety of methods to identify, visualize, and simplify polynomials with like terms. Several different visuals are used to introduce the instructional activity, such as colored pencils, overheads, interactive white...

Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

Mass and density — aren't they the same thing? This activity has groups use balance beams and water displacement to measure several objects. The pupils use the measurements to calculate the density of the objects. 

This assessment pair goes way beyond simple graphing, factoring and solving polynomial equations, really forcing learners to investigate the math ideas behind the calculations. Short and to-the-point questions build on one another,...

How do we clean up oil spills and other pollutants in the water? Explore water treatment strategies with a set of environmental science experiments. Groups remove oil from water, work with wastewater treatment, and perform a water...

There are many ways to work through a multiplication problem. Using an area model, kids complete several worksheets with different types of multiplication problems, including multiplying by ten, and explain how the new strategies differ...

Youngsters discover the difference between estimating and guessing. They estimate how many items are contained in a jar as they read a story. After the story, pupils discover the differences between estimating and guessing and create a...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

It might be silly to determine the creep rate of putty but groups will enjoy making different formulations of silly putty and playing with them to understand how the different mixtures behave. The second part of the activity has groups...

Let there be light. The last installment of a seven-part series has pupils conduct an experiment on light attenuation through different numbers of transparency sheets. They then relate the results back to how X-rays measure bone density.

Solving a murder is like isolating a variable. Using a video on a murder mystery, the narrator introduces the idea of solving a literal equation for one variable. After solving several equations, the class comes up with a set of...

Clay itself sinks, but clay boats float. Why? Young engineers build clay boats to learn about buoyancy. They test the weight the boats can hold using washers and then tweak their designs to make improvements, following the engineering...

Class members create their own social networks by collecting signatures before graphing the interactions with their fellow classmates. The degree distribution of the simulated social network is determined by calculating the degree of...

Math novices examine how math can help them in real-world situations. They listen to the book The Math Curse by Jon Scieszka, solve various word problems from the book, explore various math websites, write original math word problems,...

Corn stalks and pumpkins, caramel apples and cider, falling leaves and brisk nights. There are a few of autumn's favorite things. But how safe is that unpasteurized cider bought at the roadside stand? Young researchers investigate the...

Learners investigate how rocket thrust is generated with propellant. They listen to a teacher-led lecture, discuss Newton's third law of motion, answer discussion questions, and view photos of rockets and rocket designs.

Fourth graders produce 4 small works of art that be pasted or glued onto the back of the colored construction paper. They choose crayons, watercolor markers, watercolor paints, or colored pencils to produce their designs.

Students develop and practice observational skills through lab activity.
