The new Science in 3D standards require students to have much more hands on learning opportunities so that they can behave like scientists in an authentic way. Use this lab for the whole class, or buy the other labs in my store to allow students to work in centers.
If you like this, check out the center pack (3 days of lesson plans) OR the entire weather/water cycle storyline! It will give you lesson plans for the ENTIRE unit and cover both standards!!
