Explore the interactions between various combinations of two atoms. Turn on the force arrows to see either the total force acting on the atoms or the individual attractive and repulsive forces. Try the "Adjustable Attraction" atom to see how changing the parameters affects the interaction.

Experiment with a helium balloon, a hot air balloon, or a rigid sphere filled with different gases. Discover what makes some balloons float and others sink.

This investigation will have students testing how heating and cooling can change the state of matter. They will test a variety of materials determine whether a change takes place through heating/cooling.

The project is called "Chemistry and Cooking" and it will last about 6 weeks. Students will learn about what matter is, the phases of matter, the difference between physical and chemical properties, as well as physical and chemical changes. The project’s Driving Question, which focuses our work, is “How does an understanding of chemistry impact your cooking?” Students will be involved in hands-on activities and labs that will help them learn the concepts that they will then apply to their final project. The child will work independently on a recipe of their choice to show their understanding of how chemistry impacts cooking.

This is a comprehensive science textbook for Grade 10. You can download or read it on-line on your mobile phone, computer or iPad. Every chapter comes with video lessons and explanations which help bring the ideas and concepts to life. Summary presentations at the end of every chapter offer an overview of the content covered, with key points highlighted for easy revision. Topics covered are: skills for science, classification of matter, states of matter, kinetic molecular theory, the atom, the periodic table, chemical bonding, transverse pulses, transverse waves, longitudinal waves, sound, electromagnetic radiation, particles, compounds, physical and chemical change, representing chemical change, magnetism, electrostatics, electric circuits, reactions in aqueous solution, quantitive aspects of chemical change, vectors and scalars, motion in one direction, mechanical energy, the hydrosphere. This book is based upon the original Free High School Science Text series.

A lesson on states of matter using marbles for molecules expands into 3 more lessons elaborating on properties of a gas.

Students develop an understanding of the maple syrup process from tapping trees to evaporating sap through hands-on experiences.

Pump gas molecules to a box and see what happens as you change the volume, add or remove heat, change gravity, and more. Measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.

This activity is a classroom lab in which students investigate and observe three types of balloons to help identify the states of matter and their properties.

This activity is an inquiry lesson where students investigate solids, liquids, and gases through a variety of hands on experiments tied into writing and illustration of observable results.

In this lesson from the American Association for the Advancement of Science, students observe what happens to a closed container containing heated water is cooled.  Students use their observations to construct an explanation of what happened.  The lesson includes suggested questions for a teacher to use to probe student understanding as they make their observations.  The lesson would be a valuable activity to include in a unit on states of matter to help students build understanding of the particle-level nature of matter.  Connections to common misconceptions are included in the resource that can be used to guide teacher questioning durign the lesson.

 
Great way to incorperate Science and literature n honor of Dr. Seuss Day. Messy and fun science! Your students will love exploring states of matter with OOBLECK! A fun and powerful way to teach matter! Teacher tested-students' approved! My students had a blast with this.  Every year when I use this, and my class loves it. This activity is great to use with the book Bartholomew and the Oobleck, a story by Dr. Seuss Once you mix it, it has a very strange consistency - like a solid in the bowl until you pick it up, then it is very liquid.

Students will investigate what constitutes a solid and a liquid state of matter. Using the probe, students' misconceptions on states of matter will be exposed. The lab, which uses a cornstarch, water and food coloring mixture, will be explored. The students will determine how that exploration will take place and devise a procedure to determine the state of matter. Students will then, as a group, present their findings to the class. After all the groups have presented their findings, the groups with the same findings will combine and defend their findings to the other group(s) until the class, as a whole, has reached a consensus.

This guided inquiry lesson allows students to make explore with materials and draw conclusions if they are a solid or liquid.

Watch different types of molecules form a solid, liquid, or gas. Add or remove heat and watch the phase change. Change the temperature or volume of a container and see a pressure-temperature diagram respond in real time. Relate the interaction potential to the forces between molecules.

This activity is a lab investigation where students observe the four states of matter. At the end of the investigation students should be able to know that the differences among the physical states depend on the distance between the atoms or molecules and on the rate of movement of the atoms or molecules. And, that pressure and temperature control these two factors.

Students act as chemical engineers and use LEGO® MINDSTORMS® NXT robotics to record temperatures and learn about the three states of matter. Properties of matter can be measured in various ways, including volume, mass, density and temperature. Students measure the temperature of water in its solid state (ice) as it is melted and then evaporated.

Heat, cool and compress atoms and molecules and watch as they change between solid, liquid and gas phases.

This activity models the states of matter and students investigate those states with a balloon/straw rocket.
