Learners construct their understanding of measurement and dimensions in this step-by-step approach that begins with an all group vocabulary introduction, consisting of measuring objects and dialoging using measurement vocabulary....

Slide books with a little assistance from Newton. Using books, groups create a demonstration of Newton's Second Law of motion. Pupils compare the distance traveled by one and two books when they apply a force to them.

A simple question, with a not-so-simple answer. Working with whole and mixed number measurements in inches, feet, and yards presents a problem with many possible solutions. A great activity that challenges the minds of young...

Teams learn about the size of a nanometer by measuring objects and converting those measurements. A worksheet then tests the groups' abilities to use nanometers by having them determine the size of objects that are too small to...

How do you measure surface tension? The fifth installment of a nine-part series is an experiment where young scientists use tubes of different sizes to measure surface tension. They calculate the average and standard deviation of the...

The scientific issue of carbon-14 dating and exponential decay gets a statistics-based treatment in this problem. The class starts with a basic investigation of carbon content, but then branches out to questions of accuracy and...

While the lesson focuses on right triangles, this activity offers a great way to practice the area of all triangles through an interactive webpage. The activity begins with the class taking a square paper and cutting in in half; can they...

Tired of waiting for hot water? Groups of three determine the efficiency of an electric water-heating device. They calculate the amount of energy it takes to heat the water and the theoretical amount of energy required to heat the water....

Not only do future engineers learn the difference between accuracy and precision, they also get some hands-on experience using different measuring tools. 

This thirteen page data analysis activity contains a number of interesting problems regarding statistics. The activities cover the concepts of average measurements, standard deviation, box and whisker plots, quartiles, frequency...

It won't take young mathematicians long to learn how to measure length with this fun, hands-on activity. Working in pairs, children use Unifix® or snap cubes to measure and record the lengths of different classroom objects. To extend the...

Break out the balances for this primary grade lesson on weight measurement. Using common elementary school manipulatives like unifix or snap cubes, young mathematicians determine the weight of four different classroom objects. A graphic...

Explore Snell's Law using thin films. In the fifth installment of a seven-part series, pupils solve a set of problems relating to Snell's Law and use this skill during an experiment requiring the collection of reflective measurements...

With minimal setup and maximum freedom, young geometers are encouraged to think outside the box on a seemingly simple application problem. Though the task seems simple, measuring a given paper clip and finding how many 10 meters can...

Jada has a rectangle board that is measured in inches. Young learners confirm their understanding of converting inches to feet. Then they find the area in square feet. Jada thinks she has a short-cut to convert inches square to square...

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

Third graders are exposed to finding the area of polygons by decomposing figures and recomposing them into rectangles. This strategy allows children to expand on their prior knowledge of constructing shapes by rearranging parts into...

Help the local elementary school fix their playground by calculating the amount of sand needed near the swing set. The problem practices setting up proportions and ratios with three different options for solving. You can chose the option...

If you have ever injured your shoulder, you know it takes a while to improve your arm's range of motion. In this real-world example, young mathematicians gain insight into the world of physical therapy while they analyze a case study...

How efficient is a motor in a LEGO set? Future engineers conduct an activity where a LEGO motor-generator system raises an object to a specified height. They then show what they learned and use their measurements to calculate the energy...

Understanding arrays is very similar to understanding the relationship between multiplication and area. Give your third graders an opportunity to practice identifying area models that relate repeated addition and multiplication. They...

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...

Make the strongest beam possible using taffy? Groups mold a taffy-water mixture into a beam and a reinforcing material of their choice. To finish the final installment of a two-part series, participants test its strength by adding...
