Students have cups of different colored water. They add a new color by using a medicine dropper and see how new colors are formed.

Students are able to prepare and use pH indicators in paper form. They find out the color of the indicator paper plus test solution may change with time. Students use red cabbage to use for the indicator.

Fourth graders explore how the landscape of the planet can be changed by different elements of wind, water, ice and chemicals through hands-on activities. They examine pictures of areas around town and discuss anything they think is out...

Second graders explore the ocean. In this science activity, 2nd graders define vocabulary and color pictures of animals that live in the ocean. Students complete a word search about ocean life.

Middle schoolers explore the concept of geometric patterns. In this geometric pattern lesson, students use Microsoft Excel to explore geometric patterns. Middle schoolers analyze growth rates of pattern growth. Students create their...

In this frogs and toads worksheet, students examine detailed color pictures of 7 varieties of amphibians. Students write the name of each frog or toad on the line. There is no word bank.

In this animal worksheet, learners complete 6 pages of activities and exercises pertaining to the diamondback terrapin. Students read about the life cycle, study habitat maps and color and cut out a three dimensional turtle.

Students observe the effects of water on four different packing materials to determine which ones are more soluble. They then decide which material would be a good packing material to use for the environment and which may be a bad...

Students conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...

Students are asked how does odors move around without energy? They relate concentration gradients, diffusion, and equilbrium and predict water movement into and out of cells. Students are shown a demonstration where the teacher sprays...

This PowerPoint enables students to review mathematical concepts that were addressed in fifth grade. This is an interactive review game where the class is divided into two teams. The team that answers the most questions right wins. Each...

Talk about Velcro®, Gecko Tape, WhalePower turbine blades, and other innovations that mimic nature to inspire your STEM or engineering class. This set of worksheets gets them thinking about imitating nature in terms of sustainable...

Fourth graders construct their own aquifer. They discover how water travels underwater and identifies sources of underground pollution. They record their observations and discuss the results.

Sixth graders observe the physical and chemical change that can occur in an acid and a base. In this acids and bases lesson plan, 6th graders use cabbage juice to identify, compare, and contrast acids and bases.

Students study watersheds and use topo maps to help explore where they are located.  In this watershed lesson students delineate their watershed on their own. 

Students comprehend that hot water rises up through cold water but cold water does not rixe in hot water. They comprehend that water at temperatures above 4oC decreases in density with increases in temperature. Students answer lab...

Students observe the currents that occur through convection in water and relate them to the currents in molten rock in the Earth's mantle. They set up a convection current in a cake pan of water using a bag of ice on one end and an...

Students discover how molecules are in constant motion. Through a simple experiment of water containing food coloring, they observe the drops of coloring move even though the water is still. Role-playing as molecules, students stand up...

Learners experiment to discover that salt water is denser than fresh water by creating color coded solutions. They examine how heavy rainstorms and high tides develop layers of different degrees of density.

Students study the physical differences between wetland and upland soils. They match colors to the different levels of the soil after digging holes. They create soil color charts and chart the texture of the soils.

Young scholars examine how circulation currents of the ocean. They use a tub of hot and cold water to demonstrate the currents. They discover how salinity and temperature of water affect its movement.

Students study salty and fresh waters.  In this harbor estuary lesson students complete a lab activity on salinity and describe what happened. 

Students investigate various properties of ice including melting points and the effect of pressure on ice. They demonstrate how increased pressure lowers the melting point of ice and perform a simple experiment proving that water is more...

Students hypothesize what they expect to see on the fabric under each different color or light. For example: under what color light do they expect the fish to be brightest before looking at an ocean scene.
