Silly Stuff
It's time to get a little silly with this fun primary grade science activity. By simply combining two liquids, white glue and corn starch, a strange solid is formed, commonly known as silly putty. To ensure everything goes smoothly,...
Curated OER
The Same, But Different
Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...
Curated OER
Practice Final
A full-fledged practice final prepares pupils for their general chemistry final exam. If they complete these 57 multiple-choice questions correctly, they will be well-prepared. Note: even though the questions are multiple-choice, there...

Activity #13 Changing The Look of Sugar
Students observe what happens when sugar is dissolved in water and when it is heated. They weigh the products after each of the two experiments on a balance scale. Pupils distinguish between physical and chemical changes. Students are...

States of Matter
Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to boil water through...
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...
Global Change
The Carbon Cycle and its Role in Climate Change
So how does the carbon cycle work? Kids participate in a hands-on activity that allows them to understand the chemistry behind climate change and global warming. They act out the process of photosynthesis by labeling themselves as...
Curated OER
Unit 1 Matter and Energy
Topping this worksheet is a comprehensive collection of notes about phase changes. The phase change graph is displayed, along with formulas for the gas laws, and information relating energy to change of phase. After reviewing these...
Curated OER
Chemistry & The Community
Students complete a Webquest which investigates the chemistry in items such as shampoo. They research the Internet, perform a lab experiment, and write a scientific lab report with their findings. Upon completion of the activities, the...
Curated OER
Phase Changes
In this phase change worksheet, students read about the particles in substances that speed up and slow down for substances to change phases. They answer eight questions about phase changes, the states of matter and how changing...
Curated OER
Greenhouse Gases: The Chemistry Behind the Culprits
Ninth graders investigate the effect of different gases in the atmosphere. In this chemistry lesson, 9th graders explain how these gases contribute to global warming. They suggest possible solutions to this growing problem.
Curated OER
Weather, Sea Level Rise and Climate Change
Students compare the carbon dioxide content of four different samples. In this chemistry activity, students research the causes of global warming. They explain how humans contribute to rising global temperature.
Curated OER
Ice Cream Chemical and Physical Changes
Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...

11 - The Heat Is On
Students observe physical change of melting by observing substance in original state, melting substance, allowing substance to return to original temperature, determining if substance retained its original properties, and recording results.

Molecules Matter
Did you know that jumping spiders sometimes wear water droplets as hats? A seventh grade science lesson introduces the concept of what makes up water: tiny molecules that are attracted to each other. Starting with a chemistry discussion,...

Chemistry - Science 10
In this chemistry science learning exercise, students identify the parts of a chemical reactions. Students name the major particles of the atom. Students apply knowledge about the atom, theories, and models.
Curated OER
Chemistry: States of Matter Quiz
In this chemistry learning exercise, 11th graders take a states of matter quiz by matching 10 terms to their definitions, decide if 10 statements are true or false, and answer 2 fill in the blank questions.
Curated OER
Elements In Chemistry: Solids, Liquids and Gases
Students investigate the kinetic-molecular theory. In this state of matter lesson, students consider the differences of melting glaciers, melting icebergs and investigate on what happens when submerged water melts.
Curated OER
Chemistry Basics Practice Exam
In this chemistry practice learning exercise, students solve sixteen problems including identifying chemical and physical changes, calculating numbers with significant figures, naming compounds and writing formulas and converting from...
