In this models of atoms and isotopes worksheet, students use marshmallow of different colors to represent the protons, neutrons and electrons in an atom. Students make models of the 3 isotopes of hydrogen. They draw a diagram of each and...

Science teams make models of four different hydrocarbon compounds that we commonly use for fuel. Then they demonstrate chemical reactions that result when energy is produced. This can be used as an enrichment when your class is studying...

Students are able to discuss the difference between a proton, a neutron and an electron. They also can explain the difference between an ionic and a covalent bond. Students know the main structure of atoms and molecules. Student are able...

There's nothing sticky about the resource, unless you count the gumdrops! Scholars create a model of a lithium atom, complete with protons, neutrons, and electrons. It's just that these models are made with gumdrops and toothpicks.

Uncover the building blocks of the universe as budding chemists explore atoms and molecules in an exciting inquiry-based activity. Investigators view an interactive video describing the chemical structure of six molecules. Using...

Chemistry classes will appreciate this color-coded, single-page reference sheet for The Standard Model of particle physics. It is divided into two main sections: elementary particles and compound particles, both with their antiparticles....

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

Very simply, pairs of learners construct a model of the tetrahedral silica structure using raisins and toothpicks. They dip it into a soapy solution and then blow a bubble "atom" into its center. The lesson plan gives instructions that...

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)...

Feeling a little uncertain about your materials for teaching the quantum mechanical model of the atom? Here is an interactive that will help! Chemistry and physics scholars alike will benefit from a simple resource that illustrates the...

Watch budding chemists interact with the resource on chemical interactions. In the unit, six lessons provide an overview of basic chemistry, from understanding the development of atomic theory to distinguishing between ionic and covalent...

Everyone enjoys combining baking soda and water. Here is a lesson that challenges scholars to analyze the reaction three different ways — the real substances, the chemical equation, and the molecular models. Class...

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...

Never trust an atom; they make up everything! Young chemists make modeling dough and add another ingredient to change the properties. Scholars then compare the properties of emulsion to composite materials. A reading passage and analysis...

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...

There is 30 percent more carbon in the atmosphere today than there was 150 years ago. The first lesson in the four-part series teaches classes about the carbon cycle. Over two to three days, classes make a model of the cycle,...

Using a copy of the periodic table, chemistry test takers fill in a chart with element name, chemical symbol, atomic number, atomic mass, and numbers of subatomic particles. They define subatomic particles, draw atom models, explain...

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...

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...

What goes into a museum display? A secondary-level STEM project prompts groups to design a museum display for the Tech Museum of Innovation. They create an analogous, interactive model illustrating a science concept to complete the...

Snap to it! Young experimenters use Snap Cubes to model how a larger object is created from a smaller parts. Using a guide, they rearrange their cubes to create all possible arrangements of four and five cubes.

I don't trust atoms because they make up everything. Budding scientists learn about famous scientists connected to atomic models, chemical, ionic, and hydrogen bonds. The presentation also presents how to count atoms...
