Fifth graders use common household items to build landforms and simulate weathering and erosion.

Third graders experiment with chemical reactions and examine what happens to the atoms when different reactions occur.  In this matter lesson students divide into groups and complete a lab experiment. 

Research the impact that changes in biotic or abiotic factors might have on an ecosystem. Debate for or against the changes and take action in the community. This resource ideally follows stream studies that young ecologists may have...

Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect...

What's the difference between a rock and a mineral? And what properties are used to identify minerals? The first installment of a five-part series on earth materials and processes prompts young scientists to identify a set of...

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.

During a three-part lesson, learners make a cabbage juice pH indicator and use it to analyze the waste products of yeast after feeding them with sugar. The intent is to demonstrate how living organisms produce carbon dioxide, which is...

Oh nuts! Do macadamias or almonds produce more thermal energy? Energy enthusiasts find out with this experiment. The objective is to demonstrate to your class how the chemical energy contained in foods can be converted into useable...

Here is the first of four experiments to differentiate among unknown liquids by their behaviors and properties. Pupils observe how different liquids respond to being placed on plastic and paper, and they take notes about their...

Through a PowerPoint presentation and the embedded animation and video, earth science enthusiasts find out about the moisture in the soil beneath our feet. In the animation, follow a water molecule on its path through the water cycle. As...

Fourth graders study physical and chemical weathering. They explain how the processes of weathering and erosion change and move materials that become soil. They create a K-W-L chart to show what they know and list what else they would...

Eighth graders investigate different gas behaviors. In this chemistry lesson, 8th graders describe how changing volume and temperature affect gas particles motion. They collect data and make a generalization about these variables'...

Students study the aspects of a forest floor ecosystem, including decomposition, the water cycle, food webs, the needs of living things, and physical vs. chemical change over an extended period. In addition, students conduct observations...

Students articulate the difference between the terms heat and temperature. They calculate the amount of energy associated with a given temperature rise and design an experiment to measure the energy of a fuel.

Learners explore the properties of matter.  In this cross curriculum three states of matter science lesson, students listen to the poem "Eighteen Flavors" by Shel Silverstein, and predict what will happen if listed ingredients are...

Students observe seeds growth and examine the different parts of the seedling. In this biology activity, students compare the growth of seeds planted in soil and in hydroponics. They record their observations in their science journal and...

Pupils view a demonstration and record and questions and observations that they have.  For this candle lesson students discuss their observations and give examples of the changes they saw. 

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Determine physical properties of potential packaging materials. Continuing from previous lessons in the series, the resource asks groups to identify physical properties of the substances. They test for conductivity, solubility, water...

Blast off! An engaging hands-on activity has pupils create rockets powered by Alka-Seltzer. They learn about the physics behind these rockets throughout the process.

If tap water is more acidic than ocean water, why are we so concerned about ocean acidification? The third installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on carbon dioxide levels in...

Students investigate climate changes by graphing and analyzing ice core data from Greenland and Antarctica. They create, explain and report the pattern of data on a graph of ice core data. In addition they find relationships between the...

Students investigate the physics of heating and cooling through conduction, convection, and radiation. Working in groups, they determine the best way to cool a can of water and warm a can of water. Temperature is taken at five minute...

In this endothermic and exothermic reactions worksheet, students experiment with water and a salt of choice to determine if heat is absorbed or released in the reaction. Students take the temperature of their solution over a 2 minute...
