Numbers that are very large or very small are difficult to express in standard notation. Pupils learn how to convert between standard and scientific notation. They also multiply and divide the numbers in scientific notation. 

This pre-assessment launches a unit on climate change and weather. 15 questions, both short answer and multiple choice, asses the classes' knowledge about these concepts. 

Can you go ice fishing in the ocean? Learners examine the freezing point of different saltwater solutions. Each solution has a different concentration of salt. By comparing the freezing points graphically, they make conclusions...

Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.

Every child's dream: stuffing as much candy into a bag as possible. Doing this, though, requires a nice sturdy bag. Scholars design the sturdiest bag they can and test the limits of those bag using a sweet treat!

Challenging and interactive—everything you need in a resource! Chemistry scholars manipulate a series of puzzles focused on molarity. The teacher's guide provides support for implementing the lesson, as well as printable materials.

Need a fun solution to teaching ... solutions? A series of puzzles provides reinforcement to key molarity terms and calculations. Science scholars determine the concentration of several solutions before using the information to solve...

How do green plastics reduce waste and environmental pollution? Budding scientists create and test a variety of compounds used in green plastics during an insightful experiment. Beginning with startling statistics and ending with...

Bring the sun to your class! Young scholars analyze actual solar wind data in the second lesson plan of a five-part series. Their analysis includes speed, temperature, and density data.

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...

How do dams support bodies of water? Scholars engage in a hands-on STEM activity where they design, build, and test dams to learn about bodies of water and how humans use natural resources. They learn how criteria and constraints affect...

Fifth graders, by doing research and seeing actual and simulated artifacts, gain knowledge of and make comparisons about clothing in the Colonial and early Republican eras with attire of present time.

Fourth graders conduct an experiment involving size and relative ability in smaller species using Madagascar cockroaches. They make predictions about how many pennies the roaches can pull, compare the results to human strength, and...

Students study the attributes of liquids. In this science exploration lesson, students participate in a hands-on activity that requires them to examine the volume and shape of liquid.

Learners explore the relationship between plant roots and the soil in which they grow. They examine photos of uprooted trees and desert areas and conduct experiments designed to highlight this mutual relationship between roots and soil....

Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

All 20 of the problems on the worksheet involve the computation of cubic volume or density. As long as your young scientists can apply the appropriate mathematical formulas, they will succeed in solving these problems. They are not...

Students investigate how water goes from a solid to a liquid then back again.  In this experimental activity students conduct their own experiment and see how water changes form. 

In this Newton's Laws of Motion crossword puzzle learning exercise, learners use the 13 clues and the terms in the word bank to help them correctly complete the word puzzle.

In this chemistry review worksheet, young scholars practice using Avogadro's number, calculating number of moles, and using the gas laws. This worksheet has 39 multiple choice questions.

Students examine and discuss the differences between clocks they are shown. Using the internet, they research how people used to tell time before clocks. They review what the long and short hand on the clock represent and practice...

In this physics rules worksheet, students complete questions and answers in order to review physics rules with each other. Students complete 26 questions.

Tenth graders organize and interpret data from a student health program.  In this physical education lesson, 10th graders use a body composition analyzer over 8 weeks to determine the validity of a student health program. ...

Discover the calorie content of foods by observing how much heat they produce in water. If you have a calculator-based laboratory (CBL™) insturment for collecting data, then this laboratory worksheet will not need any changes. If...
