Young scholars investigate density and salinity of water. In this density and salinity lesson plan, students find the density of objects and liquids and show the relationship between the salinity and density of water. Young scholars add...

In this water on planetary surfaces learning exercise, learners read about the Galileo spacecraft and the surface of Jupiter's moon Europa. They read about the energy needed to keep the water in a liquid state on Europa. Students solve 4...

Students identify and explain these vocabulary words: vibration, volume, pitch, particles, tuning forks, waves and matter. They explain that sound travels through gas, liquid and solid. They be

In this ice and water instructional activity, students read about the energy needed to transform ice to liquid water. Students solve 3 problems where they calculate the energy needed to melt ice given different scenarios in space.

For this chemical reaction worksheet, students investigate the reaction that makes curds and whey. They mix milk and vinegar and run it through cheesecloth to collect the solid. Students make observations, read about curds and whey, and...

In this periodic table worksheet, students create an advertisement for a chemical group or family they are assigned. They need to include topics such as are the elements solids, liquids or gases at room temperature, the history of the...

In this density worksheet, learners answer 16 questions related to density. They read diagrams of graduated cylinders and determine the liquid's mass, volume and density. They find the density of objects and answer 3 questions about...

Young scholars use the scientific method to determine physical and chemical properties of unknown substances. In this scientific method lesson plan, students discuss chemical and physical properties of substances as a class after a...

Students experiment with objects of different densities. In this density lesson, students examine same-sized objects with different weights, then look at a teacher explanation of density. Students make wave bottles and a density jar to...

In this periodic table worksheet, high schoolers complete a crossword puzzle given 22 clues about elements in the periodic table, periodic law, properties of elements and atomic mass and number. Students also fill in a periodic table to...

Students build conductivity testers and investigate which solids and solutions conduct electricity. Working in groups, they predict which items will conduct electricity and record their answers on worksheets.

Students define trash, garbage, or solid waste, discuss ways of disposing of trash, list examples of biodegradable materials, and have trash relay race in order to sort trash into appropriate containers labeled biodegradable, reusable,...

In this classification of matter learning exercise, students answer 15 questions about solids, liquids and gases, types of mixtures and compounds vs. elements. They also answer 2 questions about measurement and 1 question about a biome.

Students explore states of matter by concentrating on the ways in which water moves between its solid, liquid, and gaseous states in a variety of Earth environments familiar to the students. Students represent these movements in dance.

Young scholars investigate matter.  In this matter lesson, students identify types of matter and characteristics of each type.   Young scholars discuss matter and create matter posters to show understanding.

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.

Sixth in a series of 36, this lesson focuses on gases and their behavior in given situations. Learners review the states of matter and then focus on gases, specifically learning Boyle's, Charles's, Avogadro's Laws, Dalton's, and Graham's...

What better time to reinforce a concept than when you're eating? Boost scholars' knowledge of the water cycle with an eye-catching placemat featuring playful raindrops and bright colors. 

We're not talking about the kitchen sink. Learners explore what types of objects sink and float in water in an inquiry-based lesson. With experimentation, they find similarities between materials that float and those that sink.

Explore the states of matter without the mess or expensive equipment in a compact, informative activity. Scientists watch as the narrator explains the three states of matter using a glass of ice and soda in an animated video that...

Take an energetic ride through the phase changes of a water molecule in a compact activity. Young scientists learn about the phases of matter and discover the role of thermal energy in governing phase changes while watching a short...

Explore the phases of water as temperature rises. Pupils consider the idea that temperature remains constant during each phase change. An interactive exercise allows your young scientists to observe the temperature and molecular...

What makes ice, water, and steam different? Their molecular arrangements are the same, but their movements are different. Individuals make this conclusion by completing the simulation activity. 

There's more to melting than meets the eye! Junior physical chemists investigate the differences between specific and latent heats as a substance undergoes a phase change. Users remove heat from the system and observe changes in kinetic...
