Grade 2 Science
What in the World is Matter?
Put on your detective badges! Today we investigate the secret ingredient that builds everything in the universe.
Clue #1
Takes up space
Clue #2
Has measurable mass
Clue #3
Three big forms
The Two Golden Rules of Matter
Mission Briefing
1
Matter Has Mass
Mass means how much "stuff" is inside an object. It can be super heavy like an elephant, or super light like a feather!
Even tiny dust has mass!
2
Matter Takes Up Space
Every piece of matter needs room! Your desk takes up space, water fills a cup, and air fills a balloon.
Scientists call this volume!
Are thoughts, light, or love matter?
No! They have no weight or space!

Gas Mystery Slides Matter Mystery Academy • Day 4
Grade 2 Science
Can You Catch the Invisible?
You can't usually see it. You can't hold it like a rock. But it fills your lungs and blows the trees. It's GAS!
You Feel It
Wind on your cheeks
You Trap It
Inside party balloons
It Expands
Fills any room completely
The Superpowers of Gas
Particle Clues
Particles Zoom & Fly!
In solids, particles hold hands tightly. In liquids, they slide around. In a gas, particles zoom in all directions and bounce off walls!
There is tons of empty space between gas particles!
Takes ANY Container Shape
Gas doesn't have its own shape OR its own volume. If you open a bottle of gas in a huge room, the gas spreads to fill the whole room!
Blow into a ziplock bag and zip it fast to prove it!
Did You Know? A flat soccer ball weighs LESS than a soccer ball filled with air! Air has mass!
Investigation Station: Air Power
Hands-On Time
Recommended Viewing:
"SciShow Kids: What Is Air?"
Search YouTube to discover how oxygen, nitrogen, and carbon dioxide float silently right under our noses!
Watch for how air bubbles move under water!
Mission 4 Checklist:
Trap air inside an empty ziplock bag
Gently press to feel air push back
Record findings on your Gas Sleuths page
Gas is invisible, but it packs real power!

Investigation #4
1 Mission: Trap Air in a Plastic Zip Bag!
Step 1: Open the bag and swing it through the air, then zip it tightly shut.
What does the bag look like now?
Flat Puffed up like a pillow
Step 2: Gently squeeze the puffed bag with two hands.
What do you feel pushing back against your fingers?
2 Mission: The Straw & Water Cup Test!
Gently blow through the straw into the water.
What are the round bubbles made of?
Solid rock Gas from your lungs Liquid milk
Why do the bubbles rise to the top?

The ice cream holds its round scoop shape until heat starts to melt it into liquid cream!
Keeps its shape at first!
2. The Liquid
The dark soda pours smoothly and takes the exact shape of your clear plastic cup!
Flows around the scoop!
3. The Gas
Carbon dioxide gas is trapped in the soda. When it hits the cold ice cream, it rushes out as fizzy foam!
Rises straight to the top!
Scientist Prediction: Does the ice cream float or sink when soda is poured? Watch closely!
Experiment Steps & Video Fun
Ready, Set, Science!
Experiment Protocol:
1 Scoop 1 solid ice cream ball into cup
2 Slowly pour liquid root beer over the solid
3 Observe the gas bubbles rise into thick foam
4 Taste test your delicious mixture!
