From molecules to nanotubes, an engaging unit explores the world of tiny science. Fifteen hands-on experiments and lessons engage young scientists as they learn chemistry. Discussions, worksheets, and data analysis reinforce the concepts...

Believe in the invisible and convince the class that tiny particles exist even if they can't see them! A thorough lesson investigates all phases of matter and provides pupils hands-on experiences that demonstrate that all matter is made...

Middle schoolers identify he phases of matter (solid, liquid, gas), and why they take place. They comprehend what a physical change is and what a chemical change is. Students know the difference between a Mixture and a Solution.

Second graders discover what changes occur in various types of matter under different conditions. They make predictions about the changes in an apple left out in the air, water placed in a freezer, and a nail left in a cup of water. They...

For this defining water words worksheet, learners read an example of water in a specific state of matter and names of water forms and use them to create definition sentences. Students write 14 sentences.

Students make group decisions about matter as they explore and interpret many types.

Students canvass the water cycle in the seven lessons of this unit. The processes of the water cycle and the cyclical nature of water is emphasized inthis unit.

In this matter worksheet, students watch a movie and then compare the differences between compounds and mixtures. This worksheet has 16 fill in the blank questions.

In this science worksheet, students identify and locate vocabulary words related to various sciences. There are 20 words located in the word search.

Students observe chemical reactions that produce obvious effects. They begin by exploring a different substance every day for one week. They compare the substances and examine how substances can be solids, liquids, or gases.

Students make putty and explore its properties. In this colloids lesson, students identify the properties of solids, liquids, and gases. Then, they create a collide and examine its unique properties.

Students identify and describe the building blocks that make up an atom. They also compare the ages of atoms to the ages of the materials they compose,as well as, give examples that illustrate the small size of atoms.

In this matter worksheet, students identify words and match them to their definition. Students identify words dealing with matter, its physical changes, and the effect of heating and cooling matter. This worksheet contains nine...

Students examine and discuss how water changes from a liquid to a solid to a gas. They explore this concept by having an ice cube race, competing to see which group can change the solid water back into liquid water first.

Second graders conduct investigations to explore matter. In this states of matter instructional activity, 2nd graders complete four activities to analyze the three states of matter. Students analyze the properties of solids, liquids, and...

Students study the location of Earth's water and study the water cycle using a terrarium. In this water study lesson plan, students study a model globe for the Earth and find Alaska. Students locate the bodies of water and study an...

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...

Second graders explore states of matter when they change a liquid to a solid. Working students make ice cream in a zip-lock bag.

Young scholars determine the differences between the crystallization of igneous and metamorphic rocks. They examine both liquid state and solid state crystallization.

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...

Fourth graders calculate density, compare densities of solids and liquids, measure liquids using a balance, and investigate the significance of density. They conduct an experiment to determine an order of densities, and complete a...

In this scientific method worksheet, students read about the steps of the scientific method, ways to measure mass and volume and how to read a meniscus. Students use the scientific method to determine if an object is a liquid or a solid...

Students observe earth science by examining results from an experiment. In this buoyancy lesson, students practice floating different items in two different liquids and identify why certain objects will float and others sink. Students...

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.
