Changes in Matter

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

An educational lesson focuses on the idea of conservation of matter through a demonstration of the water cycle, a discussion of digesting food, and the path of carbon and oxygen atoms as they change form. 

Engage the class like never before as pupils learn to differentiate between multiple physical and chemical changes by conducting a list of small experiments, most often with household materials. They make observations and discuss the...

Focus on inquiry-based learning in your science class with a series of activities designed for middle schoolers. A helpful packet samples four different texts, which include activities about predator-prey relationships, Earth's axis and...

Heat things up in your physical science class with this interactive lesson series on thermodynamics. Through a series of class demonstrations and experiments, young scientists learn how heat is transferred through conduction, convention,...

There's a lot content packed into the four lessons of this physical science unit on density. From salad dressing to the water cycle and hot air balloons, these lessons engage students in hands-on activities that explore real-world...

Do solids, liquids, and gases even matter? The presentation focuses on changes in matter, including phases, Boyle's Law, Charles' Law, and physical changes. 

Begin a full lesson plan on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep...

Ice is nice, and its condition on the planet has a significant effect. Junior geoscientists experiment with ice melting in both water and on land to discover how each affect the rising sea level. This detailed lesson outline even...

Pairs work together to determine whether unknown solutions are either acids or bases by using a red cabbage indicator solution. After determining the general pH of the unknown solution, classmates blow into the same indicator after...
