Kinetic Molecular Theory
Students analyze and evaluate evidence that matter is made of tiny particles. They observe a series of phenomena involving solids, liquids, and gases to make inferences about the spacing, interactions and relative kinetic energies of the...
Curated OER
Alka-Seltzer Cannons
Fourth graders observe what is happening when an Alka-Seltzer tablet is placed in a clear cup of water. They observe the release of carbon dioxide gas. Pupils answer the question of how much as is released by observing the experiment...
Curated OER
Dust in the Wind; Chemicals in the Water
Students explore mechanical and chemical weathering at stations. They articulate some mechanisms of chemical and mechanical weathering through exploration in a lab. Students stations describe how chemical weathering differs from...
Curated OER
The Recycling Factory
In this density of materials worksheet, students examine ways to sort a dump truck of recycled materials using the density of the material types. Students write a letter to the city council to describe their method of sorting.

Colligative Properties - Freezing Point Depression
In this freezing point worksheet, students determine the freezing point of solutions at different concentrations. This worksheet has 9 problems to solve.
Curated OER
Ice Cream
Students are shown an experiment making ice cream while discovering the freezing point depression. There are questions for students to answer after the demostration.
Curated OER
Watching Crystals Grow
Students observe crystal growth of Epsom salts and the variables that hinder or help their nucleation and growth. They illustrate a series of drawings/pictures as the crystals grow. They look for the different shapes they form as well...
Curated OER
Bad Microbes in Food Processing
Students complete an experiment to determine if there are bad microbes in food processing.In this bad microbe experiment, students use apples to see how they react to oxygen. Students test apples with chemicals to observe the changes.
Curated OER
Ice Cream Blizzards
Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...
Curated OER
Thermochemistry
In this thermochemistry instructional activity, students calculate the enthalpy of vaporization as well as the write the thermochemical expression for the production of the chemical reaction.
Curated OER
Elements, Compounds, and Mixtures
In this matter worksheet, students review the three forms of matter by reading a poem and completing 1 matching and 5 short answer questions.
Curated OER
Oobleck and the Mystery Powders
Students listen to the book, "Oobleck," by Dr. Suess before experimenting with mystery powders. They determine the proper ratio of powder to liquid to make the Oobleck.
Curated OER
ZIPPLY Delicious Ice Cream
Second graders explore states of matter when they change a liquid to a solid. Working students make ice cream in a zip-lock bag.
Curated OER
EGG-cellent POLYMER PACKAGING DESIGN
Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...
Curated OER
Alka-Seltzer Cannons
Fourth graders examine how to conduct a reliable scientific experiment so that the results are valid. They compare and contrast the reaction of Alka-Seltzer tables, one whole and one crushed, and time how long each takes to pop the top...
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...
Curated OER
Icecream in a Baggie
Students apply their comprehension of colligative properties to real-world situations. They review the concepts of physical and chemical changes. Students are reminded that science is used extensively in food-production. They are...
Curated OER
The Exceptional Nature of Cellulose
Students observe the affects of a substance's composition and structure have on its solubility. In this cellulose lesson students compare the amount of energy required to dissolve mono-saccharides with that required to dissolve...
Curated OER
Solubility
In this solubility worksheet, learners determine which solute will be more soluble in the solvent listed. Students complete 7 matching and 3 problems to solve.
Curated OER
A Very Simple Conductivity Meter
Students conduct a simple conductivity meter to test the ionic or non-ionic nature of water samples including one from their home.
Curated OER
Ice Cream
Students explore the concept of the colligative property. Through experimentation, students lower the freezing point of a liquid in order to create a solid by using household ingredients to create ice cream.
