Students examine why some objects float in water while others sink and the ability of something to float does not depend entirely on its weight. Archimedes' principle is introduced and buoyant force is discussed. Practice calculations...

Seventh graders are given the opportunity to use model-building as a way to help comprehend the forces and phenomena at work in the world around them. They use both successful and unsuccessful models to make inferences, refine...

Students are introduced to some of the fundamental questions about the connections among population, resources and energy use, and environmental impacts. They explore population growth, interpret a line graph and calculate their own rate...

Students assess the ocean's microstructure by analyzing graphs created during tne Ronald H.Brown research cruise. they discuss at what depths various sea animals live and write paragraphs on data analysis from the graphs.

Students examine the world population data using MyWorld GIS software and compare and contrast the population characteristics of countries around the world. Students summarize their findings in a report.

In this measurement worksheet, students explore methods to measure the thickness of foil. They write an essay on how they calculated the thickness of the foil, and the number of atoms thick it is. Students create labeled sketches to...

In this science worksheet, middle schoolers identify and locate vocabulary words related to various sciences. There are 20 words located in the word search.

Seventh graders design, construct, refine, and test cars that they build on the computer screen. They find the density of several objects using the techniques used to find volume. They measure various common objects to become more...

In this periodic table worksheet, students complete a graphic organizer comparing and contrasting the characteristics of the 7 periodic families. Some of the characteristics are electron configuration, bond angle, dot diagram, polarity,...

Students visualize census data on a map and use a map key to read a population map. In this census lesson, students use a map of the Virgin Islands and corresponding worksheets to gain an understanding of population density.

In this moles learning exercise, students are given 9 problems where they find the number of grams, molecules, moles, or ions given one of these measurements and the chemical compound. Students calculate the number of atoms in a gallon...

Young scholars develop a scientific model of gas behavior. In this gas lesson plan, students observe different balloons filled with different densities of gases. They complete an activity where they model the behavior of gases using...

Students explain various scientific laws used in SCUBA diving. In this theory based instructional activity, students examine and explain how temperature, density, and salinity relate to SCUBA diving using various scientific laws to...

In this identifying units of measure worksheet, students estimate the volume of their bodies using the bath method and component method, estimate the density of their bodies and use a conversion sheet to convert metric measurements....

Third graders experiment with coins and water to explore light rays.  In this light and water lesson, 3rd graders work in pairs to observe what happens with a coin in water or how it appears based on the density of the water....

Students examine lava lamps and what causes them to work.  In this density lesson students make a lava lamp and write the scientific explanation of what happens.

This is a very basic presentation of the layers of the atmosphere. It divides the atmosphere into four layers and pretty much only mentions the elevation and order of each. The last of seven slides shows a pie graph and data table of the...

Gummy bears are tasty, but did you know they are also used to determine color and light properties? Use the activity as a way to demonstrate light absorption, light reflection, and refraction with high schooler....

Tenth graders navigate and use the online Atlas of Canada. They explain the cause and effect relationship between human settlement and the natural environment and wildlife species. They utilize a worksheet imbedded in this plan.

Students conduct a lab (with water, guar gum and sodium borate) and carefully record physical and chemical properties and changes throughout the session, and experiment with weighing by difference.

Learners investigate what happens to solids and liquids when they change from one form to another. The amount od space taken by frozen water begins the discussion and students are led to formulate their own hypothesis to research.

Students compare and contrast conditions on Mars to those on our own planet, specifically, their local or regional environments. The physical characteristics, the atmosphere, and other astronomical data is considered.

Fourth graders study the geography and population distribution of various places on earth. They utilize actual satellite images of the night sky (lights showing heavily around area of dense population) to study and make observations...

Fourth graders examine various types of rocks and record their properties. They collect rocks at home and bring them to school where they are mixed and distributed to groups of students. After writing their observations on...
