Is your class in the dark about photosynthesis? Shed some sunlight on an important biological process with a thoughtful activity. After answering questions to help determine their level of knowledge, learners work with chemical equations...

Get down to basics with these worksheets on the structure of atoms. Challenging young chemists to identify information from the periodic table and create Bohr diagrams and Lewis dot structures for different elements, this...

Do charged and neutral particles behave differently as they undergo phase changes? Science sleuths examine two types of attractive forces using an informative interactive. Pupils can vary the amount of Van der Waals attraction present...

Liquids, gases, and solids are the states of matter in which scholars investigate in a lesson plan that offers in-depth information and engaging activities that look into the three states and the changes their properties make when mixed...

Young scientists construct an understanding of molecular compounds in this hands-on science lesson plan. Using LEGO® to model the atoms of different elements, students build molecules based on the chemical formulas of common...

Tired of blowing up countless balloons to illustrate orbital shapes around an atom? Give your lungs a break and use an interactive instead! Learners observe s, p, d, and f orbitals through the first four energy levels using hydrogen as a...

Why are bricks more likely to break than bend? Young science scholars peer inside a ceramic block and examine the effects of downward force at the molecular level. Learners can apply three different levels of force before observing their...

Atoms, elements, and molecules, oh my! Teaching the fundamentals of chemistry to curious sixth graders has never been easier to accomplish. Here is a resource that pulls together everything needed to get them off to a good start,...

Begin your states of matter lessons with a demonstration designed to introduce the concept that all matter has properties. Reinforce this concept through vocabulary exploration, and the creation of atom models; salt, water, and carbon...

With instructions to adapt the activities for any grade K-12, any teacher can incorporate the concept of scale into the classroom with a simple, yet effective lesson.

This is one sticky situation! Science sleuths uncover the mystery behind a balloon that appears to be stuck to a wall using an interactive. Learners observe a neutrally charged wall before they manipulate the charge on a balloon. Atom...

When molecules of hydrogen and oxygen are combined, how does water form? Science scholars observe changes in kinetic and potential energy during a chemical reaction in an interactive. The resource features easy controls that allow users...

It's molecule magic! Skillful scholars explore the effects of different atoms on molecular polarization using an intuitive interactive. The resource displays the charge at different locations on the molecule, then adapts as the user...

How did Rutherford determine that the nucleus was the center of an atom? Take a look inside the famous Gold Foil Experiment with an interesting interactive. Learners fire a beam of alpha particles at a nucleus containing variable...

Get a charge out of a great resource! Scholars use an interactive to explore addition and subtraction of integers. They add or remove electrons in an atom model to consider its charge.

[Free Registration/Login Required] Shown here are representations of three different models of the atom. Move the name labels to correctly title each of the models with the scientist who created them.

Explore molecule shapes by building molecules in 3D. How does molecule shape change with different numbers of bonds and electron pairs? Find out by adding single, double or triple bonds and lone pairs to the central atom. Then, compare...

In this module Activity 2 investigates What holds the atoms of a molecule together?The activity will explore what holds atoms together and why they from a molecule. Bonus reading includes Same Molecules but Different Representations.
