Where in the World is Carbon Dixoide?
Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...
Curated OER
Science: The States of Matter
Third graders conduct experiments in matter to create chemical changes resulting in gases. By mixing solids and liquids, they create a chemical reaction and capture the gas in balloons. After observing the balloons fill with carbon...

A Chemical Curiosity
In this chemical change instructional activity, students review physical changes such as evaporation and condensation before working with chemical change. They conduct an experiment with vinegar and baking soda before recording the...

Ocean Acidification
Combat ocean acidification with bubbles. Young engineers create a system that reduces the acidity of water. Dry ice in water helps simulate ocean acidity, and blowing bubbles into the water results in a gas exchange that neutralizes the...
Curated OER
Solids, Liquids, and Gases
Students explore the three main forms of matter: solid, liquid, and gas. They examine concrete examples of each, using their five senses and "experimenting" to find differences in them. They find pictures of each, cut them out and past...
Curated OER
What Is the Matter with Water?
Second graders observe matter in all 3 states : liquid, solid and gas, in an ice cream soda. In teams, they are given ice and teams compete to be the first to melt their ice. Winner gets the ice cream soda. They draw examples of 3 states...
Curated OER
Solids, Liquids, and Gases
Learners explore solids, liquids, and gasses and categorize and describe the three states of matter. In this chemistry lesson, students categorize items as solid, liquid, or gas based on the definitions given by the teacher. Learners...
Curated OER
CO2 and Air Pollution
Seventh graders observe and test for the presence of carbon dioxide gas. They compare concentrations of carbon dioxide gas and conclude high concentrations of carbon dioxide gas are unhealthy for human beings.
Curated OER
Blast Off to Learning
Learners explain the laws of volume and pressure, identify what a limiting reagent is and why it is important in a chemical reaction, and distinguish between fossil fuels and renewable energy sources.
Curated OER
Bouncing Popcorn
Third graders meet a teacher challenge to work like chemists. They investigate with baking soda, water, salt, sugar, vinegar, and sprite to move a popcorn kernel from the bottom of a cup to the top. They experiment with different...
Curated OER
Sampling Carbon Dioxide
Students perform an experiment to determine which source of gas (their breath, exhaust from a car, or the air in the classroom) has a greater concentration of carbon dioxide. Students compare the colors of BTB solutions after...

Activity #16 Dancing Spagehetti
Young scholars experiment with floating the spaghetti, the gas functions like a life preserver. Pupils comprehend that a person is slightly more dense than water. They comprehend that a life preservers are made of low-density...
Curated OER
Gases Lighter and Heavier than Air
Students explore the concept of air density. In this air density lesson, students fill balloons with helium and carbon dioxide. Students determine which gases are heavier or lighter than air.
Curated OER
States of Matter
Students examine the properties of solids, liquids, and gasses. In this states of matter instructional activity, the teacher guides students through a series of experiments to illustrate each state of matter and how matter changes from...
Curated OER
States of Matter
Learners study the vocabulary of the states of matter. In this states of matter vocabulary instructional activity, students investigate and study the meaning of the words solid, liquid, and gas. They experience demonstration lessons that...

The Effects of Heat and Acid on the Enzyme Catalase
How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!
Curated OER
The "Laws" and Principles of Chemical Reactions
In this chemical reaction principles worksheet, students read about definite proportions and the law of conservation of mass. Students read about how to balance a chemical equation. Then students complete 20 fill in the blank, 2 short...

Carbon Dioxide - Sources and Sinks
Where does all of the carbon dioxide come from that is supposedly leading to climate change? Earth science pupils test animal, plant, and fossil fuels as sources in this investigation. Using an indicator, BTB, they are able to detect the...
Curated OER
Limiting Reagents and Percent Yield Problems
Twelve questions about the various calculations of mass and yield are given here. There is significant practice of molarity calculations and consideration of the reactant and product balance.

Making Oxygen and Carbon Dioxide
Some like it hot! Scholars observe both exothermic and endothermic reactions as part of the carbon dioxide oxygen cycle. First, scientists demonstrate (or watch) a chemical reaction to create pure oxygen using fire for confirmation....

Bringing The Greenhouse Effect Down To Earth (CO2 experiment)
Learners compare 4 different form of carbon dioxide and discuss the role that carbon dioxide has in the Greenhouse Effect. They then understand that the Greenhouse Effect is a naturally occurring event.
Curated OER
The "Laws" and Principles of Chemical Reactions
In this chemical reactions learning exercise, students review the law of conservation of mass, the principle of definite proportions, and balancing equations. This learning exercise has 3 problems to solve.
