What is Matter?
Matter is everything around you. If it has mass and takes up space, it's matter!
Physical Properties
Color, Texture, Odor
Hardness & Flexibility
Magnetism & Solubility
Solid
Particles packed tight & vibrating
Liquid
Particles slide past each other
Gas
Particles moving fast & far apart
"If you can't see the air inside a balloon, how do you know it is matter?"
Conservation of Weight
The Big Rule:
The weight of a substance stays the same, even if it changes form or is mixed!
ICE
50g
Water
50g
The Sum of Parts
=
Breaking apart a model doesn't lose any atoms. The total weight stays identical!
GRAVITY
Gravity is an invisible pull between objects. On Earth, it pulls everything toward the center of the planet.
"If you were at the North Pole or the South Pole, gravity would still pull you toward the middle!"
Tug Of War
Air Resistance
Air molecules "bump" into falling things, pushing Up as gravity pulls Down.
Thrust
Powerful engines provide enough force to win against Earth's massive pull.
Magnetism
Magnets can lift metal clips off the table, proving forces can beat gravity.
Finding Proof
Scientific Claim
"Matter stays the same weight even when it melts."
Scientific Evidence
"A 50g block of ice was weighed after melting, and the water was still 50g."

Claims & Evidence
"Objects fall to the ground because Earth pulls on them. However, a piece of paper falls slower than a rock. This is not because gravity is weaker on paper, but because the air pushes up against the paper's large surface area."

The Secret Strength of Falling Things
By Dr. Alistair Gravity May 12, 2026
Imagine dropping a bowling ball and a feather at the same time. Which one hits the ground first? If you are on Earth, the answer is obvious: the bowling ball. For centuries, people believed this happened because heavier objects were simply "better" at falling. They claimed that the heavier an object was, the faster gravity would pull it down. However, modern science has proven this claim to be false. Gravity pulls on all objects with the exact same intensity, regardless of how much they weigh.
The Tower of Evidence
The first person to challenge the old way of thinking was a scientist named Galileo Galilei. Legend says he climbed to the top of the Leaning Tower of Pisa and dropped two spheres of different weights at the same time. To the shock of the crowd below, both balls hit the ground at almost the exact same moment. This observation provided the first real evidence that weight does not determine how fast an object falls.
Pisa Exp.
"The true master of the fall isn't weight—it's the invisible battle between gravity and the air itself."
The Invisible Battle
The real reason a feather drifts slowly while a ball thuds down is a force called air resistance. Because a feather has a large surface area compared to its weight, it catches the air like a tiny parachute. The air molecules push upward against the feather, fighting against the downward pull of gravity.
Upward Push
In a famous 1971 experiment, astronauts on the moon dropped a heavy hammer and a light feather at the same time. Because there is no air on the moon to push back, both objects hit the dusty surface at the exact same moment. This proved the reason for the feather's slow fall on Earth was the air, not gravity.
The Law of Staying the Same
Furthermore, we must remember that matter cannot simply vanish. This is known as the Conservation of Weight. Whether you melt an ice cube into liquid water or boil it into an invisible gas, the total weight of the matter remains the same. Even if you mix salt into water and it "disappears" through solubility, the weight of the final mixture will be exactly equal to the weight of the salt plus the weight of the water.
Evidence Investigator
1. The author claims that "weight does not determine how fast an object falls." What specific evidence does Galileo provide to support this?
2. How does the 1971 moon experiment support the claim that air resistance—not weight—slows things down on Earth?
3. According to the text, what happens to the total weight when salt is mixed into water? Use the term "Conservation of Weight" in your answer.
4. Scientific Claims vs. Evidence: Match the claim to the specific reason/evidence used to support it.

Briefing: Scientific Forces
Matter follows specific rules. Conservation of Weight means that melting, boiling, or mixing doesn't make matter disappear. Gravity pulls everything toward Earth, but forces like Air Resistance or Magnetism can fight against that pull. Finally, Solubility is when a solid dissolves into a liquid to form a mixture.
Task: Classify the scenarios below by recording their Letter in the correct category zone.
A
Ice in a Bag
100g of ice melts into 100g of liquid water.
B
Parachute Drop
A skydiver slows down as they fall toward Earth.
C
Stirring Sugar
Sugar completely disappears into warm water.
D
Moon Landing

Sorting Scientists Activity
Mission Briefing (Instructions)
Step 1: The Hook (10 mins)
Anticipatory Set
Hold up a container of water and a container of salt. Ask: "If I mix these, will the total weight be more, less, or the same?" Use Slide 1-2 to introduce the concept of Matter and Physical Properties.
Questioning Framework:
"What happens to the sugar when it dissolves? Does it vanish from the universe, or is it still there? How can we prove it?"
Step 2: Direct Instruction (20 mins)
Guided Notes
Hand out Lab Notes . Guide students through Slides 3-5 . Explicitly model the ELA integration on Slide 6 by showing how a "claim" in science requires a "receipt" (evidence).
Common Misconception
Students often think "mass" and "weight" are the same. Explain that weight changes on the moon (due to gravity), but mass (the stuff you're made of) stays the same.
Teaching Tip
Use physical movements! Ask students to "feel" gravity pulling them down and simulate "air resistance" by flapping their hands like a bird.
Step 3: Evidence Investigation (25 mins)
Guided/Independent Practice
Students read the Gravity Mystery Passage . Work together to identify the first claim in Mission 3 of the Lab Notes . Then, students move to the Sorting Scientists Activity to apply their knowledge.
