Take your class inside a beaker for an up-close view of a chemical reaction! Junior chemists examine how chemical reactions occur using an interactive resource. The activity allows users to change the temperature and observe how it...

Scholars complete a crossword puzzle in this chemistry worksheet with 20 questions about chemistry concepts like atoms and chemical reactions.

Don't overreact! A simple experiment demonstrates chemical reactions as scholars mix chemical solutions and metals in a large well plate. They note all changes to the metals, solutions, precipitate, colors, and more. A full data table...

When an organism eats, how does food become energy? Young biologists follow glucose through the process of cellular respiration to the creation of ADP using a discussion-based activity. The resource also highlights conservation of mass...

Malleable, magnetic, mesmerizing metals! Pupils love learning about metallic elements, especially through the hands-on activities in an engaging lesson plan. The resource provides thorough instruction on the properties of metals, the...

Did you know baking powder can be used to treat acne, whiten teeth, and make sugar cookies? The instructional activity on the development of baking powder is ready-to-go with no preparation required. Through readings, pupils answer...

By working through this web-based activity, students differentiate between ionic, non-polar covalent, and polar covalent bonds. Specifically, distinctions are made between bonding types based on orbital shapes and electronegativity...

This StudyCards stack enables students to review the vocabulary that describes chemical bonding.

In this activity, students explore reactions in which chemical bonds are formed and broken. Students experiment with changing the temperature and the concentration of the atoms in order to see how these affect reaction rates. They also...

Students discover that ionic bonding occurs when electrons are transferred from one atom to the other and not shared as in covalent bonding.

After observing a demonstration of a chemical reaction between a burning candle and the oxygen in the air, young scholars use atom model cut-outs to model the reaction and see that all the atoms in the reactants show up in the products.

This simulation helps students investigate the basics of chemical equations. Students will review stoichiometry and what effects their reaction rates.

Follow the energy conversion from potential to kinetic in this interactive activity that explores total energy in chemical reactions.

Media-rich lesson in which students discover that it takes energy to break bonds, and that energy is released when bonds are formed during the process of dissolving. They also determine whether dissolving is either exothermic or...

In this module Activity 3 investigates What changes in energy occur when atoms rearrange during a chemical reaction? This activity explores the relationship between energy and chemical reactions. A bonus reading includes Energy and...

In this activity, students construct models of molecules using marshmallows and gum drops.
