Students experiment with water and ice. For this states of matter lesson, students explore how water can change from a solid to a liquid and back again. They discuss and write about the results of the experiment in a science journal.

First graders categorize matter. They compare how solids and liquids behave.

You can't unring a bell, but can you unmelt an ice cube? Readers consider reversible and irreversible changes with a short informational reading passage and accompanying comprehension questions.

Students observe the diffusion of air molecules through a balloon. In this chemistry and molecules lesson, students fill balloons with air and a scented substance and observe whether the scented air is able to permeate the balloon.

Young scholars 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 density worksheet, high schoolers review this property of matter and the mathematical equations for density, mass, and volume. The worksheet has 10 fill in the blank statements and 3 word problems.

First graders break into groups of five students and are given 15 different objects and 3 posters. They group the objects into 3 different families with all the objects in each category placed on one of the posters. They choose whatever...

Students complete a unit to learn about sound; students include multiplication and division problems along with rate problems. In this sound lesson, students complete 7 separate lessons with multiple activities to learn about sound.

The sun sends the earth 35,000 times the amount of energy required by all of us on the entire planet, every day. The fourth lesson in the 10-part series looks at how light energy from the sun transfers into thermal energy. Scholars build...

Here's a terrific Jeopardy-style game that's designed for 3rd and 4th grade students of science. The topics include living things, animals, plants, matter, and "hodge-podge." The questions are all age appropriate, and there is an...

In this weird water worksheet, students read for information and assess comprehension. In this true and false, fill in the blank, and multiple choice worksheet, students answer ten questions.

Students perform experiments in pairs to visualize the changes in water during freezing and melting. In this properties of water lesson, students use their senses and inquiry tools to understand the changes in state of water. Suggested...

In this thermochemistry instructional activity, learners indicate whether the given processes are endothermic or exothermic reactions. Students complete the phase change diagram as well as define a given set of vocabulary words. Learners...

Students identify the various states of water. They use hypothesizing and hands-on experimenting on changing the states of water, the properties of water, and the role of heating and cooling in the changes of state.

Fourth graders create a simple testing device and collect and observe the pollution in the air we breathe.

Students investigate how dirty air is outside. They read and discuss the book, The Lorax, by Dr. Seuss. They investigate using jars and lids to compare the dirt left each day as they remove the lids. They observe the lids and discuss if...

Students work in teams of four as they conduct four controlled Jell-O experiments over a two-day period. The Family Page extends this learning to the community by providing families with challenges to explore at home.

Young scholars experiment with force and motion. In this force and motion instructional activity, students test gravity using a variety of objects. Young scholars rotate through a series of stations which use force, motion, friction, and...

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final instructional activity in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter...

Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

Third graders gain appreciation of water by watching online video, "Weather Smart: The Water Cycle and Clouds," exploring how water cycle works, comparing and contrasting three states of water as solid, liquid, and gas, and discussing...

Learners move with control in general space. They move with three different spatial distances and tempi. Students demonstrate understanding of the distance and speed of particles in matter: solid-close and slow; liquid-medium distance...

In this chemical change worksheet, students review physical changes such as evaporation and condensation before working with chemical change. They conduct an experiment with vinegar and baking soda before recording the chemical changes...

Learners investigate the process that occurs when liquids evaporaate. They test water and alcohol to determine which substance evaporates more quickly and relate the rate to energy changes.
