Tech Lesson 07-5: Molecule Simulator
(Idea created by Nicholas Barreira - 5th Grade Smith's class 2008)
Demonstrates understanding of basic technology and telecommunication
Operates Basic technology tools and applications
CSTA Level I Standard 4: (3rd to 5th) Use general purpose productivity
tools and peripherals to support personal productivity, remediate skill
deficits, and facilitate learning throughout the curriculum.
CSTA Level I Standard 5: (3rd to 5th) Use technology tools for
individual and collaborative writing, communication, and publishing
activities to create presentations, and publishing activities to create
presentations for audiences inside and outside the classroom.
M5P4 Students will make connections
among mathematical ideas and to other disciplines.
S5P2 Students will explain the
difference between a physical change and a chemical change.
a. Investigate physical changes by separating mixtures and manipulating
paper to demonstrate examples of physical change.
b. Recognize that the changes in state of water (water vapor/steam,
liquid, ice) are due to temperature differences and are examples of
c. Investigate the properties of a substance before, during, and after
a chemical reaction to find evidence of change.
Student Scratch program must have at least 10 molecules that use
motion and bouncing to simulate the movement of molecules and states of
matter (solid, liquid, gas) depending on energy (temperature).
1. Has at least 10 molecule sprites
2. Each molecule moves and bounces off edge and each other
3. Each molecule moves faster and slower depending on the energy
1. Molecules "stick" closer together when energy is lower.
2. Molecules move farther apart when energy is higher.
3. Label sprites show the states of matter (solid, liquid, gas) at
different energy levels.
Process: (Directions for Students)
(Step By Step Detailed
1. Draw one molecule with Scratch
2. Create Scripts to allow molecule to move about screen randomly and
bounce off the edge
3. Create Variable to simulate energy (speed) and have the molecule
move faster and slower depending on energy
4. Copy the molecule to create at least 10.
5. Use label sprites to show change between states in matter (solid,
liquid, gas) depending on energy (temperature)
6. Save your file with name: "Lastname Molecules"
Scratch Project shows at least 10 molecules that bounce off edge and
Molecules move slower and closer together as energy variable is lowered.
Scratch Project shows at least 10 molecules that bounce of edge.
Molecules move slower as energy variable is lowered.
