Students work together to create a model of the Earth. They label and identify each layer and describing its properties. They discover how engineers use models to test different concepts.

Fourth graders read the fiction selection, Dolphins at Daybreak, and then the corresponding non-fiction books about dolphins and sharks. They use a specific research model to find information about dolphins and sharks from books and...

Students simulate the three types of plate boundaries using robots. For this earth science lesson, students explain how earthquakes and volcanoes are formed. They collect real-world earthquake data and plot them on the map.

In this atom model worksheet, students explore how scientists developed the Bohr-Rutherford atom model. Students complete 15 fill in the blank statements.

Students use CERES percent coverage surface data with a world map in locating landmasses and bodies of water at Earth's Equator.

Students are introduced to Microsoft PowerPoint. Using the internet, they research a topic of interest to them related to science. They create three slides and share them with the class. They also discover how to print the slides and...

Students investigate the characteristics of different soil samples. In this physical science instructional activity, students play the role of forensics solving a crime by matching soil from the suspect's shoes. They formulate a...

Students describe major topographic features on the Patton Seamount, and interpret two-dimensional topographic data. They create three-dimensional models of landforms from two-dimensional topographic data.

Students participate in an angular solution of hydrogen activity. Using this activity, students also illustrate eigenvalue problems applied in mathematics. They explore Schrodinger's equation and particle wave duality.

Students compare and contrast the volcanoes of Earth and Mars, and examine specific volcanoes on Mars. They model the processes that create cone and shield volcanoes, and measure the slope angles of cone and shield volcanoes.

Caesar ciphers hide secret missives. A simple interactive lets users encode and decode hidden messages. The cipher method here is the Caesar shift.

Machines can be so helpful sometimes. A simple interactive has learners enter input values for a function machine and observe output values. These values help determine a function that represents the input-output relationship in the...

Take a look at data from a statistical lens. An interactive allows pupils to enter data set, labeling the data including the units used. Manipulating the applet, learners select the statistics to calculate that include total, mean,...

Introducing ... the Transmographer. Young mathematicians investigate translations, reflections, and rotations. The applet lets users perform transformations on triangles, squares, and parallelograms.

What does the graph mean? Pupils view 10 graphs and determine whether they are possible based on their contexts. The contexts are distance versus time and profit versus time.

Students analyze how engineers study temperature inversions and convection currents to understand why pollution levels may be higher in some areas than others. They participate in an experiment that allows them to build simple models to...

Learners view a demonstration of how groundwater flows and define several related vocabulary terms. They complete a worksheet, participate in discussion and make a poster.

Students examine fossils to understand how they are formed and how they give information about geological history. In this fossil lesson, students research and write about fossils and make models of different fossil types.The PDF...

Students explore plant and animal cells. Using household items, students create a three-dimensional model of a plant or animal cell. Students identify and label each cell part.

Students are introduced to the different types, designs and nature of bridges. They observe a historical look at the bridges in and around the Pittsburgh area through a video presentation. Connections are made between science and...

Students assess what a dichotomous key is and how it identifies objects in a group through a process of answering yes/no-type questions about certain objects. They examine an interactive graphic key on sea turtles and then create their...

Students investigate how kidneys function. They discuss how a dialysis machine works, and conduct an experiment in which they filter different substances through a plastic window screen, various sizes of hardware cloth, and poultry...

Students examine the causes of tsunamis and observe a table top wave making machine. They make model houses while working in groups so that the can see how different construction types work. They discuss how engineers can design and...

Students explore the causes of water pollution and its effects on the environment through the use of models and scientific investigation. In the accompanying activities, they investigate filtration and aeration processes as they are used...
