Investigating the large numbers of science is the task in a simple but deep activity. Given a one-sentence problem set-up and some basic assumptions, the class sets off on an open-ended investigation that really gives some...

Students use the scientific method to conduct an experiment and use varied methods to gather background information. They correctly use lab equipment and prepare tables and graphs that organize, conclude, and present their findings. ...

Learners explore the physical properties of density. In this hands-on activity, students calculate density and distinguish between intensive and extensive properties.

All soil is not created equal! A lab activity asks learners to collect and analyze soil. Specific calculations determine the amount of sand, silt, and clay in a sample and allow individuals to identify the soil texture. 

Log some practice with logarithms. A PowerPoint presentation provides a tutorial on the change of base formula involving natural logarithms and solving exponential equations with logarithms in the fourth installment of a seven-part...

Seventh graders define density in their own words. In this physics lesson, 7th graders solve density problems using its mathematical formula. They explain why some objects flow and some sink.

Ninth graders develop operational definition of density, do computations using density equation, categorize pieces of matter as being able to float on water or not, based on density, explain why some objects sink or float based on...

Young scholars investigate ways to find the density of irregular shaped objects. In this physics instructional activity, students calculate density using its mass and volume. They explain why some objects float or sink in water.

Students predict the impact of population density on shelter, transportation, recreation, land use, and social skills and then research that impact on Japan. They write a response about the impact of population density on food...

Students explain what factors determine density. In this physics lesson, students hypothesize which objects are less dense. They cite the importance of density in everyday life.

Students utilize their knowledge of the physical properties of matter such as mass, volume, and density to solve a problem. They utilize the scientific method to solve a problem. Pupils analyze their data to determine whether their...

Students develop critical thinking and awareness about the complexity of natural resource use, wealth distribution, population densities, poverty, and the environment. They think about people living in different parts of the world and...

Learners participate in a science activity that integrates connections between health issues on Earth and how those issues are related to studies conducted on the International Space Station. T

Students investigate how a population of fish multiplies in an ecosystem and the kinds of things that must be done to maintain a healthy population balance with other organisms that live there. They conduct an experiment to test the...

Students, after reading from a NASA Web-based textbook, demonstrate an understanding of the text by solving problems on density and predicting which density give the most lift.

Ninth graders predict when an object will sink or float based on comparison of the density of the object to the density of the substance in which it is placed.

Clay's as good a material as any to build a boat, right? An introductory activity sets the stage for two activities associated with buoyancy. The first involves building boats out of clay, while the second uses these boats to measure the...

Elementary-aged scientists discover that all matter has mass. They are shown the difference between mass and weight, and learn how to calculate mass using the appropriate tools and methods. The scientific method is used while estimating...

First graders observe examples of the three states of matter and identify matter in each of the three states. They make glitter wands to remind them of the three states of matter: solid, liquid and gas. Pupils brainstorm and record...

Being an astronaut takes not only high mental acuity, but also a high level of physical fitness, especially for those who spend a long amount of time away from Earth, such as the astronauts serving on the International Space Station....

Students collect data and make observations on how given element samples respond to the field of a magnet and they calculate the density of the samples by finding the mass and volume.

Learners investigate several unidentified substances and suggest a use of each substance. They can explain that a substance has characteristic properties, such as density, a boiling point, and solubility, all of which are independent of...

Young scholars follow directions for a simple chemical experiment. They use the appropriate tools and techniques to gather, analyze, and interpret data. Students identify a substance that has characteristic properties, such as density,...

For this compounds worksheet, students determine the number of molecules in molar mass for given amounts of different compounds. This worksheet has 5 problems to solve.
