Students continue to learn about why we have seasons. Today I introduced the word revolution to your students and we talked about the difference of rotation and revolution.

On Monday, students reviewed rotation and used a globe to see how half of the earth is lit and the other half is dark, causing day and night.
On Tuesday, we learned about why we have seasons. We demonstrated that the tilt of the earth causes the part of the earth tilted toward the sun to have more direct sunlight making it summer. The part of the earth not tilted toward the sun does not get direct sunlight and has winter. We made a season wheel. On Tuesday we completed our Venn Diagram comparing and contrasting the day and night sky. On Wednesday we learned why we have day and night and what the sun and earth are doing when we have day and night.
We began our first unit, Sky Watchers. We drew a picture of the day sky and made a list of the objects we see in the sky. Then we drew the night sky.
Students did an observation activity in which they got a shell, observed and drew it and then switched papers with another student to see if the other student could find their shell.
Students read a "What is a Scientist?" which is a book showing children doing the same skills scientists do. We talked about how we are each scientists and the students drew a picture of themselves as a scientist.
Welcome back to a great year of science! Students practiced fire, tornado and lock down safety drills. We also went over science room rules and procedures.
