Students explore concrete. In this physical science and computer research lesson, students work in groups to answer specific  questions about concrete. Each group of students completes a different worksheet with a specific subtopic....

For this concrete girder worksheet, students use water, sand, cement and gravel to construct concrete girders. Students vary the proportions of the mixtures and label each concrete girder with the mixture's components.

Pupils examine concrete samples and guess their strength. They determine the correlation between concrete strength and the cement to water ratio that was used in making each sample. They make a quality concrete based on their findings.
