Students demonstrate the scientific method by conducting an ice cube melting experiment. They make predictions and observations, and conclude what factors make ice melt more slowly or quickly than normal.

Learners explore water and how it changes forms.  In this investigative lesson students participate in an activity that shows them how water changes form and what it looks and feels like. 

In this chemistry element worksheet, 7th graders complete three pages of activities that help them learn about solid, liquid, and gas forms.

In this states of matter worksheet, students learn about the 3 different states of matter and how matter shifts states. They then answer the 20 questions in the packet. The answers are on the last page.

Students describe four states of matter and their characteristics, explain thermal expansion of matter, interpret state changes in terms of kinetic theory of matter, explain relationship between temperature and volume of a gas, state...

Young scholars examine how a hot air balloon works. In this hot air balloon lesson, 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 moves when...

In this states of matter worksheet, students answer 4 questions about solids, liquids, gases and plasma. They compare the particles of each and draw diagrams showing the particles in each state of matter.

Students experiment with mixtures of matter. For this matter lesson, students investigate which liquids form a solution when mixed together and which do not. Students also identify which solids can be separated from matter.

Young scholars experiment with solids and liquids. In this mixtures of matter lesson, students combine matter to form solutions. Young scholars hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by...

In this heat worksheet, students determine the heat gained or lost when matter changes phases. Students review the energy flow through ecosystems by comparing trophic levels and food webs. This worksheet has 10 fill in the blank, 5 short...

High schoolers examine and discuss how atoms change from solid to liquid to gas. They inflate a balloon by melting ice that converts to steam, and discuss the results.

Students identify and describe three states of water. They predict how water will change states.

In this chemical phases diagram worksheet, students use a diagram to answer 6 questions about the three different phases-solids, liquids and gases. The diagram is of a mystery compound referred to as "X".

Fifth graders investigate the nature of matter and of the scientific processes associated with them in this series of lessons.
