Planet Earth
In this Earth worksheet, students review the characteristics of the Earth including it's rotation and revolution. This worksheet has 9 fill in the blank and 7 short answer questions.
Curated OER
Geometric Transformations
Learners examine images and preimages of a mapping and identify isometry. They view images by M.C. Escher, observe teacher demonstrations, and create a translation image, a rotation image, and a dilation.
Curated OER
INTERPRETING MAGNETIC FIELD MAPS
Young scholars interpret magnetic field maps, rotate the coordinates to obtain different views, change the coordinate representation, and produce alternate graphical representations.
Curated OER
Three D Constellations
Students are introduced to both celestial coordinates and to the first rung on the distance determination ladder. They convert spherical coordinates to Cartesian coordinates to construct a three dimensional model of a constellation...
Curated OER
Seasons
Students investigate the reason for seasons on Earth during three activities. They construct a model of the Earth and Sun to identify patterns in the changes of the angle of light on the Earth's surface. Then they conduct a heat...
