In this circuits worksheet, students read about total voltage, total resistance, and total current. Kids learn about voltage across a resistor and short circuits. After completing the reading, students complete 4 circuit questions and...

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

In this electrical learning exercise, students interpret schematics to answer a series of 31 questions about mixed frequency signals. This learning exercise is printable and the answers are available on-line.

Students determine that two figures are similar or congruent by investigating figures that are similar and figures that are congruent. They prove that two figures are similar or congruent by using definitions, postulates, and theorems.

Students experiment observing a demonstration on models of density-driven currents which are typically found in an estuarine system of water flow. They compare/contrast water temperature and salinity to the formations of estuarine currents.

Students observe changes in their classroom.  In this coping with changes lesson, students note the differences in the activities of the day  and the changes in the classroom.  Students explain changes in their lives and...

Students investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the balloon...

Students conduct an experiment.  In this glaciers lesson, students learn about glaciers and then perform an experiment to show how glaciers shape the landscape around them.  Students draw a picture in their journals to...

Third graders study the human body. In this health instructional activity, 3rd graders discuss that everyone's body is growing, measure body parts using a tape measure, and color the body worksheet.

Students explore webpages to research the nature of atoms, including electrons, protons, and neutrons. This instructional activity is the first of a four-part series on static electricity. They see that static electricity involves + and...

Learners examine the concept that static electricity is a phenomenon that involves positive and negative charges. They explore the Static Electricity section of the Science, Technology and Engineering website to learn more about the...

Fifth graders compare and identify variables that affect the rate of a chemical change using Alka-Seltzer, water, ice, and hot water. They time how long each variable takes to pop the canister into the air, and record the results on a...

For this math worksheet, students practice defining angles and work on some various problems that focus upon the fraction of a turn.

In this genetics learning exercise, students are given two coins that they mark with a "F" and a "M" to represent parents. They flip the coins to determine the genotype and phenotype of the offspring for twelve traits. They also use the...

In this averages instructional activity, students practice finding the averages of numbers. They use a chart with data to find the average number of wildfires in four states between 1993 and 1996.

Students recognize objects around their school made of rocky materials. In this changes in rocks and soil lesson, students use a website for a virtual experiment of rocks.  Students group rocks based on their properties....
