Weathering of Limestone
We all know limestone weathers, but what affects the rate of weathering? Young scientists investigate the physical and chemical weathering of limestone (chalk) through experimentation. First, they conduct trials with different-size...

Box Folding: Predict, Analyze and Measure
Young scholars predict the shape of a geometric figure in 3D. In this geometry lesson, students construct 3D shapes to perfect their knowledge of measuring and predicting. This assignment is also available as an online interactive lesson.
Curated OER
Air Expansion and Contraction
Students observe that air exerts pressure, that heated air expands and that cooled air contracts. After the demonstration, students engage in a question and answer session about what they saw.

Air: It's a Gas!
Young scholars investigate the properties of air through hands-on activities in conjunction with the demonstrations in a 3-2-1 Contact Video.

Science Buddies: Shape Changing With the Cyber Squad
In this project, you will make 2-dimensional templates, called nets, that fold up into 3-dimensional (3-D) shapes. By making shapes of different sizes, you will be able to see how 3-D shapes change with size. In your findings you will...
