Students conduct a series of investigations on the unique properties of water. For this general science lesson, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students explore a hydrometer.  In this gravity lesson students construct a hydrometer and create a liquid density column. 

Use this art lesson to study insolubility and density. Combining water-based paint and mineral oil will cause a fun and interactive painting. This is a great art project to incorporate during a science unit.

Students explore physical science by conducting an in-class experiment. In this density instructional activity, students define vocabulary terms dealing with physics and discuss their knowledge of density. Students conduct several "sink...

Students compare the densities of different liquids. In this liquids lesson plan, students compare color, viscosity, weight, volume, and graph their findings.

Students investigate why some objects float or sink in water. In this physics lesson, students calculate the density of clay ball using a mathematical equation. They write a complete lab report about the experiment.

This open-ended boat building exercise is meant to be part of a three-instructional activity series on ships. Links to the other two lessons are included. This particular part is mostly a group lab activity in which they build a boat,...

Students explore the changing density of water. In this physics lesson, students investigate how an object's density determines whether it will float or sink in water. They explain why this unique property of is important to living things.

Young scholars examine how a hot air balloon works. In this hot air balloon instructional activity, students do an experiment to test the effects of heat on density. Young scholars make their own hot air balloon and act out how nitrogen...

Students comprehend the four parameters of water quality. They perform tests for salinity, dissolved oxygen, pH and clarity or turbidity. Students comprehend why scientists and environmental managers monitor water uality and aquatic...

Pupils design an experiment to determine which liquid is water. In this chemistry lesson, students perform the experiment as outlined in their design. They record observation and formulate conclusion.

Students analyze density. In this density instructional activity, students experiment with floating an egg. Students discover that salt added to water changes the density of the water allowing an egg to float.

Students explain the importance of water in our daily lives. For this aquatic science lesson, students identify different ways to purify water and make it potable. They design and construct a water filter based on researched information.

Students investigate density. In this density lesson, students conduct an experiment using food coloring. Students observe the differences in mixing food coloring in water and oil.

Learners explain how melting glaciers affect global warming. In this earth science lesson, students investigate the change in ice density as it melts. They discuss the human and environmental impact of rising sea levels.

Students use descriptive vocabulary to discuss the attributes of matter. Then, they sort objects or pictures by the type of matter they are comprised of. Finally, students match objects of matter with similar attributes and create a...

Students investigate crude oil. In this crude oil activity, students investigate fractional distillation and use this technique to separate two liquids.

A fascinating lesson on states of matter is here for your young scientists. Dry ice is used to challenge learners preconceived notions about how solids work. They discover all sorts of interesting facts about states of matter from...

Students build a boat out of cardboard and tape. They apply Archimedes' Principle to their design.

Students examine what lies within the Earth. They research and create scale models illustrating the layers of the Earth and write skits advocating a travel plan to send a probe into the Earth's mantle.

Students identify the characteristics and composition of emulsions. In this chemistry instructional activity, students classify household products according to emulsion type. They explain how to make the best emulsion.

Students watch a video clip about German submarines lost during World War II. They work together to create their own submarine out of a plastic bottle. They test the buoyancy of the submarine in different activities.

Students identify and complete activities about the structure of the Earth. In this Earth structure lesson plan, students view a Powerpoint about the Earth's layers and complete a diagram. students compare temperatures in the Earth's...
