Science Fun with Second Grade!

Second grade has had many exciting science activities in the past few months.We have learned about force and motion as well as beginning a unit on the human body.

The students had a great time planning and designing Tinker Toy cars and ramps for their STEM project which focused on motion.We started the lesson on a Monday and discussed force and motion and how it pertains to speed.The students began by planning their cars and ramps on paper then proceeded to build the cars the following day.The object of this STEM project was for students to race their cars down the ramps and measure which car went the farthest.The class was divided up into groups of two or three students.These groups worked well together planning and designing their cars and ramps.When one particular group raced their car down the ramp and discovered that the car was not going very fast~ they had to redo the entire ramp.

The anticipation of race day was especially exciting because of the competitive nature of a few of the students.We has a first and a second place winner for the car that went the farthest after traveling down the ramp.We will continue to do these types of projects throughout the year.The students really enjoyed creating their own projects and working in cooperative groups.

Our first human body activity  in response to the question, "Why do our skeletons have so many bones?"

In this experiment students consider what would happen if their body didn't have any bones.We used baby oil,Qtips,construction paper and dark colored crayons.The students traced their hands and drew their bones by opening and closing their hand in a fist.They were able to "feel" the joints when the hand was open and then when they made a fist.Then they outlined their bones on the hand that they had drawn earlier. Using a QTip, they were able to fill in the gaps and the joints with baby oil. After the oil was dry on the paper we hung up our finished pictures on the window so that when the the light shines through we can see our "bones".
