Henry woke up for school and noticed that it had snowed. When he walked to school the grass was
frozen. When Henry went outside for lunch the snow melted, leaving puddles all over the playground.
When Henry walked home after school, the ground was dry and clear. Develop models to show

S8p1e. Please develop an atomic model for Magnesium.
How many protons? 12
How many electrons? 12
How many neutrons? 12 (most common isotope is 24Mg → 24 − 12 = 12 neutrons)
Group? 2 (alkaline earth metals)
Period? 3
S8P1a. Develop a model to show:
(Use simple particle diagrams where each shape/color = a different atom/element.)
- Element
- Description: only one kind of atom repeated.
- Diagram idea: ● ● ● ● (all same color/shape)
- Key idea: identical particles, not bonded into different molecules.
- Compound
- Description: two or more different atoms chemically bonded in fixed ratios (molecules).
- Diagram idea: ◯—● ◯—● ◯—● (each bonded pair is a molecule)
- Key idea: bonded groups (molecules) of different atoms (fixed composition).
- Mixture of elements and compounds
- Description: element atoms and compound molecules present together without chemical bonding between them.
- Diagram idea: ● ● ◯—● ● ◯—● ● (single atoms and molecules mixed)
- Heterogeneous mixture
- Description: components are not uniformly distributed; you can see regions/clusters of different substances.
- Diagram idea: [ ● ● ● ] [ ◯—● ◯—● ] [ ● ● ] (clusters separated)
- Key idea: non-uniform composition, different parts look different.
- Homogeneous mixture
- Description: components are uniformly mixed at the particle level (a solution).
- Diagram idea: ● ◯ ● ◯ ● ◯ ● ◯ (different particles evenly spread)
- Key idea: uniform composition throughout.
S8P1b Develop a particulate model for each state of matter.
- Solid
- Particle model: particles packed closely in an ordered arrangement, vibrate in place.
- Motion/energy: very little movement (only vibration), low kinetic energy.
- Liquid
- Particle model: particles close together but not in fixed positions; they can slide past each other.
- Motion/energy: moderate kinetic energy; takes shape of container (but has fixed volume).
- Gas
- Particle model: particles far apart, move rapidly in random directions.
- Motion/energy: high kinetic energy; fills the entire container (no fixed shape or volume).
- Plasma
- Particle model: like a gas but particles are ionized (free electrons and positive ions).
- Motion/energy: very high energy; electrically conductive, responds to electric/magnetic fields.
Henry’s observations — develop models to show understanding of the phase changes.
Timeline snapshots (particle-level + transition names and energy flow):
1) Henry woke up for school (snow on ground; grass frozen)
- State: Solid (snow/ice on grass)
- Particle model: ordered, closely packed water molecules in a crystal lattice (ice).
Diagram idea: [□ □ □] [□ □ □] (regular lattice)
- Process that happened earlier: Freezing (liquid → solid) — energy released (heat given off to surroundings).
2) At lunch (sun/warmer temps — snow melted leaving puddles)
- State: Liquid (puddles of water)
- Particle model: particles close together but moving past each other.
Diagram idea: ● ●● ● ● ● (close, random positions)
- Transition: Melting (solid → liquid) — energy absorbed from environment (sun/warm air).
3) Henry walked home (ground dry and clear)
- State: Gas (water vapor dispersed into the air) or removed into soil/evaporated
- Particle model: particles far apart, moving quickly, spread into the air.
Diagram idea: • • • • (widely spaced)
- Transition: Evaporation (liquid → gas) — energy absorbed (heat from sun/air); water molecules at surface gain enough energy to escape into the air.
Summary of phase-change energy
- Freezing: liquid → solid, energy released.
- Melting: solid → liquid, energy absorbed.
- Evaporation: liquid → gas, energy absorbed.
If you want, I can make simple labeled drawings you could copy into your worksheet (ASCII or printable sketches) for each required model.
