Learners characterize a physical change as something that changes to a different size, but retains its basic substance. They measure volumes using milliliters, and perform an experiment that proves that gases expand when hot and contract...

To guide learners through observations of chemical samples in the lab, this resource asks them to give all formulas and complete the attached data sheet.  There are multiple questions about categories of elements and general...

Here is part one of a two-part lesson in which scholars investigate the changing states of water—liquid, solid, and gas. With grand conversation and up to three demonstrations, learners make predictions about what they think will happen...

Third graders examine the phase change between solids and liquids and determine it to be a physical change. Ice is the perfect item to use to demonstrate this phase change. Pupils experiment with measuring and weighing solid ice and the...

Scientists have been studying exothermic reactions before they were cool. The lesson begins with a discussion and a demonstration of heat curves. Scholars then determine the heat of fusion of ice and the heat needed to...

Students explore physical and chemical changes. For this chemistry lesson plan, students will go outside to observe changes seen in nature. Students will then work in the lab to identify changes at different stations prior to doing a...

Winter weather offers a great opportunity to teach young scientists about the states of matter. This activity-based instructional activity includes a range of learning experiences, from experimenting with the rate at...

An extremely thorough presentation walks new chemists through the basics of matter. There really isn't a unifying theme, however So many topics are covered: forces, elements, atomic structure, chemical properties, compounds, quarks,...

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...

Students observe changes in water. In this lesson about water and its forms, students perform an experiment to determine how water changes. Students analyze what causes water to be solid, liquid, or gas. Students record their...

Take a "conservative" approach to planning your next unit on mass and matter! What better way to answer "But where did the gas go?" than with a lab designed to promote good report writing, research skills, and detailed observation....

Students break into four groups, starting at different stations. Each station should take about 10 minutes depending on prior knowledge of the topic. They then rotate when everyone is finished to the next station and discuss answers of...

In this chemical and physical change worksheet, students use a sugar cube and observe its physical properties both when it is whole and after it is crushed. They heat the sugar cube and record 5 properties of the matter while being...

In this physical and chemical change worksheet, students watch a movie called the "Brain POP" about property changes and fill in the blanks to complete 8 sentences which are examples of chemical and physical changes.

Students investigate friction between different surfaces. In this physics lesson, students research biomaterials that can reduce friction. They calculate efficiency using a mathematical formula.

In 1879, Sir William Crookes discovered the fourth state of matter, plasma. The presentation covers states of matter, phase changes, density, pressure Pascal's Principle, buoyant force, Archimedes' Principle, Bernoulli's Principle,...

What's the matter? Gas, solid, liquid, or plasma. The presentation covers how to describe and identify matter, changes in matter, types of matter, measuring matter, particles of matter, Democritus, and John Dalton's Atomic Theory.

Fourth graders expand their knowledge about how the physical properties of a substances can be changed. They are given multiple opportunities, using first-hand experiences and familiar objects in different contexts, to identify...

Fourth graders examine and identify chemical and physical changes in a variety of substances. They observe a vinegar and baking soda demonstration, and a water, laundry detergent, and Epsom salt mixture demonstration. They discuss the...

Once investigators have learned how their mystery liquids interact with water during the preceding activity, they now use their observations to identify them. This is an ideal conclusion to the mini unit on the properties of water. 

Blue-tinted water is added to unknown liquids that have been tinted yellow to find out how they interact. This is a memorable activity that is part of an investigation on the properties of liquids, which is part of a unit on the...

Learners identify the physical and chemical properties of matter. They review the types of matter. Students list the four states of matter (Solid, Liquid, Gas and Plasma). They recognize and describe the different types of matter.

Students experiment with mixtures of matter. In 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.

Students participate in experiments to visualize the differences between chemical and physical changes. They attempt to detect the five characteristics of a chemical change.
