Resources aligned to this objective

Records 1–6 of 6 displayed.

Archaeological soils
Students will determine components of a soil sample and evaluate how archaeologists use soils to interpret sites.
Format: lesson plan (grade 8 Mathematics and Science)
The human atom
Students will act out the role of atoms by dressing up as the atoms of designated elements. They will wear costumes with balloons representing valence electrons. The “atoms” will gain or lose valence electrons in order to achieve chemical stability. The students must then identify the charges of the ions formed.
