Curated OER
A Day at the Beach
Help learners determine the rate of change for the temperature of sand. They will collect data on the temperature of wet and dry sand over time with a heat lamp overhead. Then make a scatter plot of the data and find a linear model to...

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...
Cornell University
Atomic Bonding
Explore the connection of surface area to bonding within atoms. Learners complete lab investigations to model changing surface area with different sizes and concentrations of atoms. A flour fireball demonstration follows the labs to...
Curated OER
Hot Chocolate Lab
Students wear goggles and collect materials and then set up computer program to use the temperature probes. They insert the probe into the milk recording temperature every 30 seconds and then record the data on the table.
Curated OER
Heating Curve Lab
Tenth graders examine the heating curve of water when head is added constantly over time. They input values into a calculator as they record water temperature every thirty seconds as it is heated on a hot plate. They complete the...
Curated OER
Atoms, Kinetic Theory, Solids and Fluids
Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.
Curated OER
WATER CHEMISTRY
Students list reasons why water is important and investigate and graph the freezing points of different solutions.
Curated OER
The Chemical Nature of Water
Seventh graders simulate a Jeopardy game to examine the chemical nature of water. Among the topics featured are evaporation, water, salt, and temperature. finally, as review, 7th graders answer a battery of questions presented by the...
Curated OER
Air Pollution Over Where?
Students predict the movement of an air borne pollutant using their understanding of air currents. They determine which governments and/or communities should be contacted to be forewarned. They also explore the properties of their...
American Chemical Society
Middle School Chemistry: Air: It's Really There
Investigation shows that gas takes up space and has mass, and that the motion of gas molecules is affected by heating and cooling.

Serc: Exploring States of Matter Gases
In this series of chemistry labs, students learn about the three states of matter by observing how molecules contract or expand as they change state.
Science Education Resource Center at Carleton College
Serc: Mn Step: States of Matter: Which Will Propel the Balloon?
For this activity, learners take part in a simulation of the three states of matter where they role play being molecules. They then create simple balloon rockets and must explain why a gas is the only state of matter that can cause the...
