Activity #2 Disappearing Water
Time 20 Minutes
Materials
  • Material 1- 3 Plastic plates or lids of the same size
  • Material 2- 3 Sponges
  • Material 3- Water
  • Material 4- Triple Beam Balance
  • Material 5- Measuring cup
  • Material 6- Permanent Magic Marker
  • Material 7 – Journal
  • Material 8 - Camera
Guiding Questions
  1. Question 1- What is Evaporation?
  2. Question 2- What is Mass?
Plan
  • Plans for part 1 of activity
    • Guiding Questions to ask during this part of the activity: What is mass?
    • Anticipated Student Responses to guiding questions: Weight…..Misconception to be cleared up!
    • Students are to put a sponge in each of 3 plastic bins or lids of the same kind.
    • Label each container with 1, 2, or 3.
    • After pouring 250ml of water on each sponge, measure the mass of the container using a triple beam balance. (Make sure to balance the scales before measurement.)
    • Place one container in a closet, one container in a window sill, and the third container on a counter in the room.
    • Students will photograph their sponge and record initial observations in their journals.
  • Plans for part 2 of activity……24 hrs. later
  • After balancing the triple beam balance, measure the mass of each of the containers again.
  • Students will again photograph and record their observations.
  • Plot the change over the 24 hrs. on a line graph using different colors.
    • Guiding Questions to ask during this part of the activity: What happened to the water? Where did it go?
    • Anticipated Student Responses to guiding questions: The water went into the air.
    • Analyze the graph and discuss the changes in the mass of each container.
    • Be sure to discuss that the water did not disappear, that it evaporated and this caused the water to go into a gaseous state.
  • Strategy 1- Practice and discussion on using the triple beam balance
  • Strategy 2- Powerpoint on evaporation for further discussion
ELL Modification
  • Modification 1- Powerpoint on evaporation for further discussion
  • Modification 2- social interaction
Check for Understanding

How you will assess or check for student understanding throughout this activity.

Students will journal about the activity and what is happening.
