In this Plinian eruptions worksheet, students read about the types of volcanic eruptions and about Gaius Plinius Secundus who the Plinian eruption was named after. Students answer four critical thinking questions about volcanic eruptions.

Students make observations. In this sensory skills lesson, students use their senses as well as tools that sharpen their senses to make observations regarding foods and other items.

Young scholars discover how flight is possible.  In this physics lesson, students investigate the properties of a blimp and gyro-copter, comparing rotating wings and fixed wings of aircraft.  Young scholars create their own...

Students explore the concept of paleoclimatological proxies.  In this paleoclimatological proxies lesson, students explain isotope ratios in deep water coral samples.  Students write a paragraph about global climate change as...

Students explore "matter." In this literacy and three states of matter lesson, students listen to Bartholomew and the Oobleck by Dr. Seuss, then work in groups to explore "oobleck" (cornstarch and water mixture) with their five senses....

Students compare cell structure to the structure of a city. In this cell structure lesson, students investigate differences and similarities between cell structure and city structure. Students create a 3-dimensional, edible model of a cell.

Students teach others about habitats. In this Science lesson, students use a Science Log to record data about a habitat for research. Students analyze the data and construct an eco-chamber. Students share what they have found with other...

Students assess the damage natural forces have caused Maryland's geographic features. In this state geography and ecology lesson, students work in a group to research ways in which weathering, erosion, and deposition have affected the...

Third graders view photos of machines that measure wind energy and chart what they observe in the pictures and the questions they have about the pictures.  For this wind energy lesson, 3rd graders make a pinwheel.  Students...

Students plant daffodil bulbs. In this gardening activity, students work outside to plant daffodil bulbs in the autumn so that they can grow roots and emerge by spring.

Students engage in a lesson that is concerned with the allocation and finding of water resources. The location of different settlement areas is considered as one looks how the water is distributed. They map some of the early Spanish and...

Students explore the differences between surface water and ground water. They collect data using maps and graphs and investigate a Texas river basin and a nearby aquifer. They complete a written report of their findings regarding the...

Ninth graders research the importance of maintaining an unpolluted water source in their community. They work together in groups and brainstorm ideas on what they can do to help. They can also write their local politicians.

Second graders study how sound is produced by vibrations and is transmitted through matter in all directions. They observe how sounds are produced and identify the ways in which sound travels.

Fifth graders study the physical properties of minerals in order to identify them. They examine how minerals are used before taking part in a activity in which they market toothpaste made from specific minerals.

Students perform an experiment in which they test foods for the presence of proteins, carbohydrates, and lipids. They identify the molecular structure of each type of biomolecule and then discuss how biomolecules relate to nutrition and...

A set of questions on weathering and erosion are found in this resource. Some of them can be used as discussion topics or lecture guides. There are also suggested activities such as the examination of topographic quadrangles and the...

In this food chain worksheet, students review terms associated with food chains and food webs. Students also recall the water cycle.

Third graders classify and sort different types of beans to be introduced to the classification system in science. As a class, they identify the characteristics of living and non-living organisms and make a chart in their journal to ...

Students explore the concept of mass balance, flow rates, and equilibrium using a simple water bucket model. In this JAVA based online interactive modeling activity, they vary flow rate into the bucket, initial water level in the bucket,...

Students analyze the global temperature record from 1867 to the present. Long-term trends and shorter-term fluctuations are both evaluated. The data is examined for evidence of the impact of natural and anthropogenic climate forcing...

Students participate in a group review activity in order to prepare for an exam. Students study together in their teams prior to the review activity. During the game, the teacher spins a wheel with subject categories written on it and...

Students use an interactive online mass balance model to observe levels of chlorofluorocarbons over the past few years. Students evaluate the influence protocol emissions will have on the future levels of CFCs.

Students examine the differences between snow and rain. In this precipitation lesson, students measure one inch of rain and snow to calculate the amount of liquid water. Students use a snowfall "conversion" chart to measure how much...
