Students weigh and record the mass of various objects, and then compare the weights of objects by holding gram weights in one hand and the object in the other hand.

Third graders explore forms of matter through reading, hands-on science activities, and research using the Internet. Students create a booklet, directions given, that they title and decorate, to later serve as a review visualization...

You're going to wish you had a watermelon for this lesson! Class members read about watermelons and make a salad in class to sample. They also perform estimates, measurements and calculations on a watermelon. They predict what percentage...

Students investigate methods of estimating through cooperative group activities, hands-on activities, the use of tables and graphs and an interactive video.

Sixth graders investigate the concept of an angle. They classify an angle according to its type. The lesson has students practice with acute, right, and obtuse angles. A unique part is when telling time using clock hands is related to...

Learners use a Colorimetric test to measure pH and gain the importance to life in an aquatic ecosystem pH is. They explore the dramatic effect pH level can have on a water body. Students test the pH level of many water samples.

Students examine what Eratosthenes is and the history behind him.  In this earth instructional activity students complete a hands on activity to repeat Eratosthenes' experiment.

Students analyze velocity and how it is determined. They experiment with velocity in order to measure and calculate the magnitude of speed. They use examples in their novel "Skateboard Renegade" to relate velocity to real life situations.

This activity could be used in a home economics class to teach students about sewing and clothing. Using this 10 question instructional activity, learners explore the function of a sewing machine, and plan a project.  

Students research how water is used to generate electricity. They investigate water's potential-to-kinetic energy transfer in hands-on activities about falling water and waterwheels. They take measurements, calculate averages and graph...

Middle schoolers explain necessity in using accurate instruments when measuring, and how measurements can be checked for accuracy. They make a six-inch ruler, design, test, and evaluate a system to measure work, and produce a table and...

Students visit a 2nd and a 4th grade class to measure the heights of older students using large building blocks as a non-standard unit of measure. They can also measure adults in the school community. Results are displayed in...

Learners work in small groups. They grab a handful of ice, and place the ice in an empty beaker of ice using a triple beam balance. Students heat up the beaker of ice over a hot plat until the ice has changed into water. They measure...

In this density of the human body activity, students measure several parts of the body to calculate the body volume. Students convert the body volume to body mass and body density.

Learners explore the metric system. In this science lesson plan, students familiarize themselves with the metric system as they participate in a hands-on activity.
