Why is it warmer in the summer?? Science Starter Why is it warmer in the summer?? Many textbooks say that Earth’s tilt causes the seasons. But how does the tilt cause the seasons to change? Use the cards at your groups to organize the statements into 1 of 3 categories: 1. Explains why it is warmer in the Summer 2. Does no explain why it is warmer in the Summer 3.

Time to practice! We will be doing stations a little different this time. Today we only have 3 stations and you will be rotating around the different areas of the room You will each receive a sheet of blank paper and you are to fold it into 3 equal parts. Number each part Station 1, Station 2, and Station 3 and draw a line to separate each section

Time to practice! Each station will have a learning activity and then something for you to complete (draw, write, model) At each station you must complete the objective and make sure you have all of the information needed! (You can take notes if you wish) You will have only 10 minutes at each station, work quickly! Odd tables go to the front stations, even tables go to the back stations

Return to your seats, put everything away except for notebook, stations sheet and pen/pencil! (First 2 groups ready=2 points)

Lesson Essential Question What causes the seasons?

What causes the Seasons? The direction of Earth’s axis always stays the same as we circle the Sun When the Northern Hemisphere tilts toward the Sun the days are longer, so there is more time for the Earth to warm up When the Northern Hemisphere tilts towards the Sun then the Sun appears higher in the sky viewed from the United States, so sunlight is more concentrated and intense.
