Second Grade Life Science- Seeds

Introduction to Second Grade Life Science- Seeds

This Second Grade Life Science- Seeds lesson allows students to explore seed dispersal and biodiversity through a fun series of hands-on projects.   Introduce the students to the topic by reading the book A Seed is Sleepy by Dianna Hutts Aston.  Then you will complete worksheets and projects to give the students an understanding of the ecology and adaptations behind seed dispersal mechanisms.  Wrap up the lesson with an assessment which covers the lesson objectives and the NGSS.*

Step 1: Download the Second Grade Life Science Seeds on the Move lesson and complete the worksheets

Here is a sample page from our worksheets  for this lesson:

Step 2: Complete the seed sorting and biodiversity worksheets

Sort the collection of real seeds into the categories on the poster the best your child can.  Then continue to have them sort the pictures of seeds found in the lesson as well as the biodiversity Internet search.

Here is a video of our seed sorting:

Step 3: Make the seed models and answer the questions about each found in the lesson

Here is the sequence for making the helicopter seed model.  The exact instructions are found in the lesson.

Here is a video of our helicopter:

Here is the sequence for making the parachute seed model.  The exact instructions are found in the lesson.

Here is a cool slow motion video of our parachute:

The seed explosion model is pretty easy, just place a bean or seed on a toy popper and watch the seed shoot away from the popper when it turns inside out.

Here is a video of our seed explosion model using a toy popper,beware of Jack singing loudly in the video, lol:

Here we are examining Velcro hooks up close and using a fish hook and a piece of thread to represent how some seeds are like Velcro.

Step 4: Complete the assessment from the Second Grade Life Science Seeds on the Move lesson
