Here children explore the sun’s warmth and observe how heat causes change in bags of chocolate





Title – Exploring the Sun’s Warmth
By – Nikole Colson
Primary Subject – Science
Grade Level – 1

Texas Essential Knowledge and Skills Science Standards:

    Science 7B: Identify and test ways that heat may cause change such as when ice melts.

Learning Objectives:

  • Feel the difference between a shaded object and one that was placed in the sun.
  • Write in the Science Journal about the way the sun affected chocolate.
  • Explore the sun’s warmth on the chocolate.
  • Predict what will happen to each piece of chocolate.

List of Materials:

  • 2 plastic bags per student
  • 2 pieces of chocolate per student
  • Science Journal
  • Discovery Book or other text
  • Hand wipes (optional)


    The students must have their desk cleaned off and must be awaiting instructions.


    The students will sit at their desks quietly and wait to be called to the carpet to read the book. Students will be working individually during the experiment.

Establishing Set/Motivation/Introduction:

  • Read (about changes in matter) out of the Discovery Works book.
  • After reading, the class will predict what will happen to the chocolate in the shade and the chocolate in the sun.


  1. After the predictions, line the class up at the door.
  2. Hand out two bags to each student with one piece of chocolate in each. Remind the students that they may not eat the chocolate!
  3. Take the class out to find a shady spot and a sunny spot for their bags of chocolate in the recess area.
  4. As soon as everyone has put the bags down, play the weather game (acting out types of weather) for about five minutes.
  5. Before ending the games, ask the students what they think all those (weather) noises sounded like.
  6. Instruct students to grab their bags of chocolate, then get in a single-file line, walk back into the classroom, and set their chocolate on their desk.
  7. Instruct students to get out their Science Journals. On the top half of the page, draw the melted chocolate. Then on the lower half, explain how the sun effected the chocolate.
  8. Raise your hand for the teacher to come and check your journal when you are done.


  • Were we right with our predictions?
  • What happen to the chocolate that was in the sun?
  • What happen to the chocolate in the shade?
  • What do you think would happen if you put a bucket of ice in the sun?
  • (Optional) What do think will happen if we touch the unmelted chocolate with our warm fingers and put it in our warm mouths? Let’s find out!
