Science and the Ocean Ranger Disaster
Students investigate the scientific theories behind various elements of the Ocean Ranger disaster. They present their information in a format of their choosing.
Curated OER
Change Agents
Third graders experiment with three erosive change agents. They do an observation log, which they present to the class through a song, poem or skit.
Curated OER
Volume
Third graders complete scientific investigation to determine what volume is and how it is determined by size not by mass. They discuss what they know about volume before proceeding with the demonstration and experimentation. After the...
Curated OER
Acids & Bases: What's the Solution?
Students conduct an experiment called "What's the Solution? Acid, Base or Neutral." to determine the differences between these types of substance.
Curated OER
Acid Rain
Students create acid rain using carbonic, nitrous, nitric, and sulfurous acids.
Curated OER
Volcano Demonstration
Students watch a demonstration on how volcanoes work. In this volcano demonstration, students watch the teacher demonstrate a volcanic eruption. The teacher will change variables used to create the eruption and the students will predict...
Curated OER
Discovering Chemical Changes
Fourth graders predict what happens in a teacher demonstration of a chemical change, before watching it. They observe the demonstration and list what the see on the board before determining which represent chemical change. Working at...
Curated OER
Physical and Chemical Changes - Making Toffee
Fourth graders make toffee to observe both physical and chemical changes. They determine what types of changes that are caused by the cooking process and which are chemical, and which are physical. In order to do this they follow a...
Curated OER
HOW IS PH DETERMINED?
Pupils estimate the pH based on the use of an unknown substance, determine whether an unknown substance is acid, base or neutral, and evaluate, by the pH determination, which of the unknowns is the strongest acid or base.
Curated OER
Clouds and Your Weather
Seventh graders identify clouds and the weather associated with them. They use informational articles and personal weather observations to learn about the relationships between weather fronts and clouds.
Curated OER
Centrifugal Force and Mandy Sue Day
Fourth graders explore the story Mandy Sue Day and investigate centrifugal force. They demonstrate the concept of centrifugal force, use analytical thinking and they conduct an experiment using centrifugal force. Students discuss the...
Curated OER
Endothermic or Exothermic That Is the Question
Students conduct an experiment to determine what happens to heat energy during a chemical reaction. They examine an endothermic reaction by observing a chemical reactions.

Making soap you can use
Those textbook experiments are no good. Using this simple method you can make a real bar of soap. It's
Curated OER
The pH scale
Students list the common properties of acids and bases. They classify substances as acids or bases, by using pH and litmus tests and are able to explain the pH scale. They participate in a lab activity which reinforce their understanding.
Curated OER
Weathering and Erosion: Some Ways the Hydrosphere Affects the Geosphere
Students explain the causes of erosion, describe the effects of erosion, and devise a method of preventing erosion. They model the before-and-after-effects of erosion.
Curated OER
Candy Cane Chemistry
Fourth graders, in groups, examine the effect of heat on bonding forces by doing laboratory work.
Curated OER
What Is the Freezing Point?
Middle schoolers remove heat energy and determine how it causes a phase change.
Curated OER
Glucose Factory
Fourth graders determine, through laboratory activity, the presence or absence of glucose in a variety of plant leaves and stems. They work in groups and perform a three part laboratory which shows them how plants convert sunlighht to food.
Curated OER
Ecosystems
Students work in small groups to create a poster illustrating the flow of energy through a typical ecosystem, then present their posters to the class.
Curated OER
Project Geode
Students predict the appearance of a geode's internal structure based on its mass and density. They form a hypothesis based on the data they collect. They also identify common minerals found in Illinois.
Curated OER
How to Read a Thermometer
Students' temperature is measured using an instrument called a thermometer.
Curated OER
Does the Sun Influence the Temperature of the Earth?
Students explore whether the sun influences the temperature of the earth.
Curated OER
Taste Buds
Students sample several sweet, sour, bitter and salty foods. They determine what part of their tongue tasted each flavor.
Curated OER
Physical Habitat of a Stream
Students measure in metric units and use a stopwatch, calculator. They collect data with minimal instructions after the initial pre-activity briefing, then record data in the data sheets provided.
