Entropy, it isn't what it used to be. Presentation includes kinetic-molecular theory, heat and internal energy, thermal equilibrium, temperature scales, laws of thermodynamics, entropy, latent heat of fusion, specific heat, calorimetry,...

First graders explore the properties of matter. In this states of matter lesson, 1st graders conduct scientific investigations that require them to mix, cool, and heat objects in order to observe changes in the properties of matter.

Students describe the motion of solids, liquids and gases. In this chemistry lesson, students describe how temperature affect motion of the particles. They determine the physical properties of each phase.

Learners compare slime recipes. In this properties of matter lesson, students make Oobleck and glurch and compare the properties of each and examine the solid and liquid properties of them.

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

Bored with your current biome bag of tricks? This bundle is a bountiful bag of biome fun! Travel the globe with seventh graders and explore the biotic and abiotic factors that define our world's biomes. Then, introduce a little...

Seventh grade scientists weigh in on the concept of density. In a nutshell, they participate in the following activities: Measurement of the mass and volume of fruit in order to compare densities Measurement of the mass of oil and water...

For this matter worksheet, learners review the states of matter and the gas law formulas and equations. Students then complete 7 multiple choice questions and 6 problems.

In this phase change activity, students read about the particles in substances that speed up and slow down for substances to change phases. They answer eight questions about phase changes, the states of matter and how changing...

Students differentiate the different phases of matter. In this chemistry lesson, students conduct several hands-on exercises to discover how matter transforms when mixed together. They identify the different stages in the water cycle.

Open this instructional activity by giving a brief history of ice cream. Using liquid nitrogen to lower the temperature, preteens make their own confection. The accompanying activity sheet queries learners about freezing point, the...

Students use a simple physical model of the Earth, sun, and moon to understand why the moon changes phases from the perspective of Earthly observers. They hold up balls representing the moon in a room with a single light source to see...

The presentation covers Fahrenheit, Celsius, and Kelvin scales for temperature as well as conduction, convection, and radiation.

In this phases of matter worksheet, students complete 13 fill in the blank spaces with science words from the given word bank. The blanks are placed within an informational paragraph about solids, liquids, and gases. 

In this chemical equations worksheet, students identify the reactants and the products, state what phase each is in, and state the mole ratios of all the products and reactants. Students complete 10 problems.

Eighth graders analyze questions posted on a large poster in the room and work in groups to record their response to the question on paper, rotating to the next question after two minutes have passed. They review the characteristics of...

Fifth graders explore the phases of matter, make observations of matter, the physical and chemical properties of matter, solutions and mixtures, formation of molecules and atoms and molecules all through hands on activities.

Students observe phase change of matter by making ice cream in bags. In this states of matter lesson, students work in pairs to churn their own ice cream in plastic bags. They make predictions about how long it will take for the milk to...

Focusing on the large animal industry the production of meat products, this information may prove to be sensitive matter to some members of your class.  However, the slides are relevant. They delve into the topic of animal labor....

Searching for a relatively interesting way to demonstrate Charles' Law? Here is a lesson in which pupils heat air inside a flask and then cool the flask to quickly cool the air. They make observations about what occurs during the...

Seventh graders divide into small groups to construct several models. Each group builds with an accompanying chart showing the colors of gumdrops used for the protons, electrons, and neutrons.)

In this heating and cooling curve instructional activity, students use a given graph of a substance being heated from a solid to a liquid and then a gas over time. They use the graph to answer eleven questions about the phases of the...

Fourth graders identify the characteristics of a simple physical change. They describe objects by the properties of the materials from which they are made. Students discuss the different states of matter and their distinct physical...

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...
