Middle schoolers use the scientific method to discover the role of a candle's wick and how radiation allows candle wax to change from solid to liquid to gas. They work in small groups to use the steps of the scientific method approach in...

Learners examine the consequences of behaviors and what the concept of trade offs are.  In this good decision lesson students read an article and answer questions on making good decisions. 

Students model the arrangement of particles in a liquid. They use the model, to demonstrate how a gas is formed from a liquid with no increase in temperature as energy is added. Pupils model the arrangement and movement of gas particles.

Pupils determine that some liquids are able to evaporate more readily than others. They create a balance using cups and a ruler to determine which end of a strip dipped in alcohol or water evaporates the fastest, hence loses the most...

Third graders sing a piggyback song to explore the parts of the water cycle and then illustrate and label the water cycle in their science journals.

Students investigate how to find the density of fluids and solids using math. Students also learn how to find the density of regular and irregular shaped objects.

Students investigate the meaning of potable water and water reuse. They define water quality and quantity problems. They complete worksheets, a quiz and design a poster.

Young scholars 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.

Pupils investigate the properties of heat. They explore methods of temperature control and measurement. Through experimentation and activities, students design a high tech tree house. They consider electrical, solar, and natural heat and...

Learners observe the melting of ice and explore the basic physical changes that occur. They gain information of how different substances change the rate of melting. Students discuss the properties of water and ice, the definition of...

Students examine the water cycle. In this hydrologic cycle instructional activity, students follow the provided procedures to demonstrate the how water moves around the planet through the dynamics of the water cycle.

Learners predict when an object will float or sink based on comparison of density of the object to the density of the substance in which it is placed. The access a website and sketch the object in the first column of their table and then...

Nothing says organization quite like a table. The third lesson in a six-part Mixtures and Solutions unit teaches young scientists about elements and the periodic table. They learn how the periodic table is organized and about the...

Learners characterize a physical change as something that changes to a different size, but retains its basic substance. They measure volumes using milliliters, and perform an experiment that proves that gases expand when hot and contract...

Sixth graders identify different animals native to Illinois. They research a specific animal to study more about its characteristics, examine what makes a habitat, and recognize the difference between a food web and food chain.

Students use critical thinking skills to learn about light, sound, and matter. Students follow the procedure steps to complete a light, sound, and matter experiment.
