Rock Types 2
All rocks include two or more minerals but greatly vary in appearance. The online interactive encourages scholars to match the rock types to the facts they know about each. They then complete three grid puzzles reviewing the same...
Royal Society of Chemistry
Elements 2
Did you hear about the chemist reading the book about helium? He couldn't put it down. Scholars match 12 chemical elements, including helium, to their symbols. Then they complete three Sudoku-style puzzles using these names and symbols...
Royal Society of Chemistry
Periodic Table 2
While the periodic table looks complex, it is really arranged by only two variables, atomic number and electron configuration. The set of four puzzles focuses on groups 3, 4, 5, and 6 or 13, 14, 15, and 16, depending on your periodic...
Royal Society of Chemistry
Periodic Table 1
Richard Feynman predicted the periodic table might go up to number 137—but never to 138. Scholars practice naming which elements belong in groups 1, 2, 7, and 0 on the periodic table in puzzles. They work through four puzzles reinforcing...
Royal Society of Chemistry
Naming Binary Compounds
Penguinone is an organic compound named because it resembles a penguin. Scholars match the name of binary compounds to the elements in each compound. Then, they solve three sets of puzzles reviewing the same content.
Royal Society of Chemistry
Formulae of Compounds
Many people confuse the chemical formulas for copper carbonate and copper oxide. A set of challenging puzzles review commonly confused compound names and their symbols. Through a series of four puzzles, pupils match the names and...

Everyday Chemicals (Ages 11-14)
Caustic soda helps break up clogs in drains in many homes. Scholars match 10 chemical names to their everyday names; for example, caustic soda is sodium hydroxide. Then, they complete three different grid puzzles practicing this skill.
Royal Society of Chemistry
Elements 3
Many pupils mix up the chemical symbols for calcium, carbon, and copper. These entertaining puzzles help scholars remember the names and symbols. First, they match the name and symbol of 12 elements. Then, through a series of three...
Royal Society of Chemistry
Hazard Symbols
Starting in 2015, all chemicals must have a pictogram of the associated chemical hazards. A brain-building activity reviews four of the basic symbols found in a typical science laboratory. Through a fun puzzle, scholars apply their...
Royal Society of Chemistry
Elements 4
Don't miss the silver lining when you are looking for gold. A brain-bending interactive allows scholars to sharpen their puzzle skills while reviewing chemical elements, including silver and gold. First, pupils match 12 chemical elements...
Cornell University
Bacteria Take Over and Down
Bacteria outnumber all other forms of life on Earth. Scholars observe the growth of bacteria in petri dishes to understand their role in maintaining good health. Then, they observe the growth of bacteria after they introduce...
Cornell University
Radical Reactions
The radical reactions of polymers seems abstract to many pupils, but this lesson turns them into a fun building game. Scholars use dice and building pieces to build polymers. Then, they determine the theoretical and experimental weight...
University of Texas
Lives of Stars
Stars exist from a few million years to over 10 billion years, depending on their mass. Scholars perform a play acting as stars to learn about their different life cycles. They develop an understanding of many of the fundamental concepts...

Nonvascular and Simple Vascular Plants: Mosses to Ferns
Sometimes conservationists use specific plants to prevent erosion or fight invasive species. A 50-slide presentation covers both nonvascular and vascular plants. It discusses the plants, their stages and life cycles, reproduction, uses,...
Concord Consortium
3D Exploration of Bound Antibody and Antigen
Our body manufactures antibodies that are the exact shape for the antigens it encounters. The simulation shows a 3-D model of an antibody and antigen pairing. It allows young scientists to explore the complementary shapes.
Concord Consortium
Protein Folding Exploring
The potential energy of peptides varies over time as they fold. An exploratory simulation encourages pupils to play with various strands of amino acids to observe the folding and potential energy levels. Young scientists generate all...
Concord Consortium
Protein Folding
Long strings of amino acids fold themselves into stable peptides. The simulation allows scholars to observe the process in multiple ways. Using hydrophobic, hydrophilic, or a combination of proteins in three different solutions, the...
Concord Consortium
DNA: The Double Helix
Picture a double helix as a twisted ladder. Scholars see this image through a simulation that allows young scientists to observe a small fragment of DNA in many different formats. They compare the models, colors, bonds, and strands as...
Concord Consortium
Mutations
Are some mutations more damaging than others? An engaging simulation encourages scholars to alter DNA through insertion, deletion, and substitution. It then forms resulting amino acids—or not—and the resulting protein—or not—depending on...
Concord Consortium
Modeling Transcription
Transcription makes copies of the instructions inside all living things. Scholars use the simulation to separate DNA and transcribe the RNA. They see a demonstration of the nucleotide pairings as well as the start and stop instructions.
Concord Consortium
DNA to Protein
Starting from a view of cells, a constructive simulation shows every step of building a new protein. It walks through transcription, translation, building amino acids, and folding the protein. Viewers control if it plays as a video or...
Concord Consortium
Diffusion Across a Permeable Membrane
Oxygen and carbon dioxide freely cross cell membranes. The simulation demonstrates the diffusion of these across a permeable membrane. To create a great visual for users, it graphs the balance of molecules as it changes throughout the...
Concord Consortium
DIffusion and Molecular Mass
Does molecular mass affect the rate of diffusion? The simulation allows scholars to experiment with diffusion while varying the molecular mass and temperature. The timer automatically stops when a certain point is reached, making it easy...
