Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly instructional activity, learners use scientific...

Students use satellite data to see the correlation between sea temperature and sunlight in the Gulf of Maine.  In this phytoplankton instructional activity students use Excel to analyze data. 

Young scholars describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas,...

In this comet instructional activity, students will read information about the Comet Halley that has been collected by recent space probes. Students will use this information to complete 7 short answer questions.

Students compare Jupiter and Earth. In this Earth and space studies lesson, students compare the composition of Earth and Jupiter and analyze how the composition affects the rate at which the planets spin.

In this refraction worksheet, students will explore the property of light called refraction. Students will conduct a quick experiment to understand how light is refracted. Then students will complete 2 short answer questions.

In this tomography activity, students read about how tomography is used to help oceanographers learn more about the Earth's surface below the ocean. Students complete 3 short answer questions based on the reading.

Students identify the contents of a glacier like those found in Patagonia. They construct a mini glacier model in class. Students compare and contrast the classroom model with Patagonian glaciers. They label specific parts of the...

In this science worksheet, 3rd graders focus on the weather. Students respond to ten fill in the blank questions regarding weather terminology.

Middle schoolers investigate crude oil. In this crude oil lesson, students investigate fractional distillation and use this technique to separate two liquids.

In this science worksheet, middle schoolers look for the words that are related to the theme of the sheet in the word search. They also work on spelling skills.

Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.

In this experiment, students look at Deep Hypersaline Anoxic Basins, or DHABs, that are present in the Eastern Mediterranean, and make a model of a DHAB to investigate how liquids that have different densities can form layers. This...

After young scholars conduct the two associated activities, Density Column Lab - Parts 1 and 2, present this lesson to provide them with an understanding of why the density column's oil, water and syrup layers do not mix and how the...

How do the densities of vegetable oil, water, and corn syrup help them to form layers in a cup? Students will carefully pour vegetable oil, water, and corn syrup in any order into a cup and discover that regardless of the order they are...

A lab activity to show students how different densities of liquid layer on top of each other by using four different colored liquids that contain different levels of salinity. This activity can also be used in an ocean unit where...

Concluding a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate densities of several household liquids and compare them to the densities of irregularly shaped objects (as...

Of course it can, you say: ice is water and ice floats. And you're right. But we're talking about water in the liquid phase Can liquid water float on water? The goal of this project is to investigate what happens to layers of water with...

This site gives background information to ocean water and its contents. It has a link to an detailed chart showing the minerals and their content amount in ocean water. It also has links to activities.

An introduction to density, mass, and volume with links to related books and activities.

Students contrast the densities of oil and water in this lab activity. Can be done in groups or individually. This resource is in PDF form; requires Adobe Reader.

Extensive site for teachers provides some helpful resources that pertain to plant and animal cells. Includes a microscope diagram as well as plant, animal and pond labs. Also contains links to structures and mechanisms, matter and...
