Young scholars explore an estuarine system to gather data on density driven currents. This type of current is contrasted with temperature and wind driven currents.

Students examine how differences in the temperature and salinity of the water help create ocean currents. They perform an experiment which shows how temperature affects the circulation of ocean water.

Students investigate scientific concepts and inquire about physical states of matter. The transition of water is considered and is easy to facilitate because of its abundance and often observed physical changes.

Students use this design the illustrate how ink can be separated into its component chemicals using paper chromatography. They use five unknown samples of ink on pre-labeled chromatography strips are provided to students. Students use...

Students explore how density can cause things to sink or float by experimenting with a jar, oil and corn syrup.

Pupils discuss the relationship of density to stratification. In this marine science lesson, students create a model of upwelling events using cold and warm water. They discuss how water phenomena affect coral reefs.

El Nino, La Nina ... and the Santa Maria? The 11th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program explains the mechanism of El Nino/Southern Oscillation. Pupils use previous data to determine...

In this 3rd grade science instructional activity, 3rd graders complete a total of 25 multiple choice questions related to grade 3 concepts. An answer key is given.

For this science worksheet, 6th graders take a multiple choice quiz about properties, energy, formulas, and more. Students complete 30 questions total.

High schoolers experiment with solubility and bonding.

In this metric units and properties instructional activity, learners determine the proper metric unit given a variety of measurements for specific items. They also identify chemical and physical properties and chemical and physical changes.

Young scholars examine different types of landscapes through a geographer's eye. Using a city block or a suburb, they organize their thoughts and take notes to survey a site. They discuss what they have seen and write about how looking...

In this grade 5 science test learning exercise, 5th graders complete a 30 question multiple choice quiz covering a variety of grade 5 concepts. 

In this thermodynamics worksheet, high schoolers learn about insulators and conductors. Students compare the three ways thermal energy is transferred: conduction, convection, and radiation. This worksheet has 22 matching, 1 multiple...

In this thermodynamics worksheet, students read about conduction, convection and radiation. They answer 47 questions about heat transfer, thermal equilibrium, insulators, conductors and the states of matter.

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,...

Students identify and complete activities about the structure of the Earth. In this Earth structure lesson, students view a Powerpoint about the Earth's layers and complete a diagram. students compare temperatures in the Earth's layers...

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.

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...

Students explore the concept of air. In this gravity instructional activity, students perform various experiments that deal with gravity, air resistance, and air pressure.

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

High schoolers examine and discuss how atoms change from solid to liquid to gas. They inflate a balloon by melting ice that converts to steam, and discuss the results.

Students explore convection and how it happens in the earth's atmosphere.

Students explore physics. In this science lesson, students discuss physics in their everyday lives. Students complete a physics worksheet.
