The Kindergarten Class came to the science lab today to learn about why we have seasons. First, though, they watched Google Earth to see the Earth from space and moved in closer and closer until they reached our school.
They learned that the Earth is spinning or rotating and they even tried rotating like the Earth. They learned that the Earth, while rotating, is also moving/revolving around the sun.. The students practiced rotating like the Earth and then they rotated while revolving around the center desk.
Ms. Brunning used a lamp to represent the sun and a beach ball Earth with a light sensor attached, to collect data on how much light the Earth received while rotating and revolving around the light. The sensor sent a signal to the computer and displayed a number for light intensity and a line graph showing the increase and decreaes with the seasons. Students observed that the light from the sun was always there and the darkness came when the Earth turned and one side was not getting light.
Ms. Brunning used two digital resources with the students:

The science lab has been rearranged so that there is a closed off prep area in the back of the room and more white board in the front of the room. Watch for the addition of more book shelves and terrariums with different habitats.
