Does the change in energy of matter lead to a change in mass? Upcoming chemists compare the mass of equal-volume, but different-temperature liquids and materials both before and after a chemical reaction has occurred. In another...

What does size have to do with it? Learners analyze different mixtures, both homogeneous and heterogeneous, to discover the properties related to the size of their particles. The activity connects these properties to those of...

Show young chemists what a chemical reaction looks like with two parts of a hands-on experiment. First, learners conduct a wet lab where they observe the reactants (baking soda and calcium chloride, with phenolsulfonphthalein)...

Students investigate how information about the atom has been determined. For this atomic structure lesson, students draw what they think an atom looks like. They conduct Internet research about the types of atomic models and how...

Scholars use sorting cards to try to define a pure substance versus a mixture. Risk becomes reward as they observe the differences and create a flowchart sorting matter into mixtures and pure substances (elements and compounds).

"Up and Atom" is a mini-unit introducing middle-schoolers to the wonders of elements. Participants draw atom models, examine the periodic table, compare samples of metals to nonmetals, identify unknown elements, and more! The beginning...

How are chemical bonds similar and how are they different? Provide your young chemists with the resources to more thoroughly understand the concepts of ionic and covalent bonds. Pupils research these topics, diagram examples of each...

Learners explore the components of matter. They discover what matter is, the states of matter, and how heat and cold cause it to change states in an online format. In addition, they complete internet-based lessons, activities, and quizzes.

Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

Sixth graders experiment with mixtures. In this chemistry instructional activity, 6th graders determine which mixtures are considered heterogeneous, a suspension, a solution or a colloid. Students create a data sheet of what they discover.

Students engage in a lesson about the scientific concept of matter. They use essential questions in order to guide the research process. Students engage in several class inquiries that are hands on in order to investigate the properties...

Students examine the differences between elements, compounds and mixtures. Using diagrams, they compare and contrast atoms and molecules and describe various chemical reactions. They distinguish the differences between ionic and...

Young chemists perform an experiment to determine if a compound is iron (II) chloride or iron (III) chloride. Then they determine the formula, balance the equation, and answer analysis questions. 

Fifth graders investigate chemical reactions. In this physical science lesson, 5th graders make dry ice root beer and identify the type of change that occurs to the root beer mixture.

Students complete a unit of activities to learn about states of matter and how to measure matter. In this matter lesson plan, students complete 8 lessons to learn about matter, its states, and how to measure matter.

Students create a foldable to help them remember topics on chemical compounds. For this physical science lesson, students differentiate ionic and covalent compounds. Given certain compounds, they identify whether it's ionic or covalent.

Students investigate the concept of elements and atoms. They conduct research using a variety of resources and use the information in order to create a class presentation. The lesson includes specific dialogue and steps for the teacher...

Learners are introduced to the elements on the Periodic Table and what is meant by element. Using the Table, they identify the name, atomic mass, number and symbol of each element. To end the lesson plan, they discover the...

Eighth graders analyze physical change in mass. In this chemistry lesson plan, 8th graders describe, measure and calculate the amount of physical change occurring in mass before and after the change. Students should be familiar with...

How can you turn an ice cream activity into a scientific investigation? It's easy if you know ionic compounds, heat transfer, and the exothermic and endothermic process. Learners will explore the science behind freezing, insulation, and...

Anytime you make concepts clear with role playing or hands-on experience, it's a win for the whole class. Ping-Pong balls are used to represent carbon in a carbon cycle role-play activity. In small groups, children first discuss what...

Sixth graders complete several experiments about chemical and physical changes. In this physical and chemical science instructional activity, 6th graders complete 6 experiments about chemical and physical changes. Students examine the...

Fifth graders study the properties of metals and use them to identify different properties.  In this metal properties lesson students complete a demonstration .

Students explore energy by researching fuel usage on Earth. In this fossil fuel lesson plan, students define fossil fuels, the energy created by burning them, and the impact on the environment when using them. Students conduct pollution...
