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
Amounts of Dissolved Oxygen in Various Bodies of Water
Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Capturing Carbon Dioxide
Why don't we just capture carbon dioxide in the air and store it somewhere else? A hands-on lesson allows scholars to explore a complex concept. First, they will create a carbonated beverage, and then they will determine if liquid...

Developing Tests to Distinguish Between Similar-Looking Liquids
Each group talks about how to test unknown liquids based on their findings in the previous experiment. In this second of four activities, they test unknowns on wax paper, newspaper, and construction paper. As a stand-alone, this lesson...

Can Photosynthesis Occur at Saturn?
In the 19th activity of 22, learners determine if distance from a light source affects photosynthesis. Participants capture oxygen in straws and find that the amount of water the gas displaces is proportional to the rate of photosynthesis.
Santa Monica College
The Density of Liquids and Solids
There are underwater rivers that flow on the ocean floor thanks to a difference in density. Scholars learn about the density in both liquids and solids in the second lesson of an 11-part series. They then determine the density of water,...

What Is Heat?
If objects have no heat, how do they can gain and lose it? Scholars experiment with heat, temperature, and specific heat of various substances. They create definitions for these terms based on their own conclusions to complete the fourth...
Curated OER
Water's Edge Café
Students observe water birds feeding at a local wetland, record what they see, and construct an appropriate menu for a "Waterfowl Cafe." They also play a "flocking" game.
Curated OER
Sources of Potential Groundwater Contamination
Students construct models that demonstrate potential sources of contamination. Students select one type of contamination model (septic system, sinkhole, landfill, disposal lagoon, leaky barrels, oil spill, agricultural contamination) to...
Curated OER
Water Pressure Blaster
Third graders complete an experiment to introduce them to the concept of water pressure. In this water pressure lesson plan, 3rd graders create pressure in a water bottle and observe the force of water that is created.
Curated OER
Temperature
Several slides compare different temperature scales. Thermal expansion, heat transfer, and Maxwell speed distribution are also explored. The last two slides seem unrelated to the topic of heat, but are easily left out of this otherwise...
Curated OER
Earth's Water
If the majority of our planet is covered with water, why do we need to bother conserving it? With a thorough and varied investigation into the location and types of water on the earth, learners will gain an understanding of why this...
Curated OER
Water in the Atmosphere
A slide show serves as the backdrop for a instructional activity on the moisture in Earth's atmosphere. Through it, mini meteorologists learn about the attributes of the atmosphere and actually use data-collecting weather tools to make...
Curated OER
Water in Earth's Hydrosphere
Environmentalists test stream water for temperature, pH, and turbidity. Each group shares their information and then the class makes an overall evaluation of the water quality. A slide show sets the backdrop for the teaching portion and...
Curated OER
Water in the Biosphere
Environmental explorers examine the campus and take note of living organisms. Introduce them to the biosphere and the questions of the day: How much water can be found in the biosphere? A slide show helps you along, and even contains a...

Gumdrop Atoms
There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.
