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...

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.

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...

She threw sodium chloride at me—that's a salt! Scholars match acids to their formulas as well as their salt compounds. Completing a series of three gridlock puzzles reinforces each of the matches in a logical manner.

Scientists call ions with a negative charge anions. Scholars work through one matching puzzle and four logic puzzles reviewing the chemical formulas for anion ions. Each level increases in difficulty and solidifies the concept in pupils'...

When two liquids combine and a solid forms, the new substance is called a precipitate. Scholars test their knowledge of hydroxide precipitates and their properties. A series of four increasingly difficult puzzles challenge their logic...

One chemical formula—but how many different structures? Familiarize young chemists with the concept of isomers through simple, related games. Users identify each isomer base upon its name, structure, and type of isomerization in a set of...

Is your chemistry class frustrated by the multitude of representations of organic molecules? Add some challenging puzzles to an otherwise ho-hum organic lesson and let the fun begin! The second of a two-part activity focused on basic...

Ready to introduce the realities of molecular geometry to chemistry pupils? Use a logic-based interactive! Perfect as individual practice, the puzzles explore the bond angles and repulsions present in three common molecular shapes.

Learning names and formulas can be a daunting task for young chemists, so support their study with interactive puzzles! First, users match each formula with its correct name. Then, individuals use them to complete three logic games.

Scientists identify elements by the color of flame they produce because each element is defined by exactly one line on the emission spectrum. By completing a series of puzzles, scholars reinforce their knowledge of the results of flame...

Magic squares make learning fun! Seriously! Learners use the given square to review vocabulary terms from J.D. Salinger's Catcher in the Rye. The 16 vocabulary terms are not divided by chapter, they represent the whole book. As learners...

Turtles might be slow, but class will zoom by when your pupils build a program in which reptiles draw a grid. Using App Lab and JavaScript, class members build a program to find the most efficient way to draw an image of a...

How do spacecraft detect magnetic fields? The fourth installment of a five-part unit has learners develop a device with magnets that allows for the detection of magnetic fields. They use a map of an imaginary planet to try out their...

One of the biggest challenges for beginning scientists is figuring out the names of the equipment! Introduce your chemistry class to essential lab apparatuses using a series of related games. Pupils pair images of a test tube, funnel,...

Lab tools are cool! But, which one is the right tool for the job? Young scientists participate in a series of puzzles focused around some common lab equipment. Each puzzle requires learners to associate the tool with its image and a...

Most mnemonics for remembering the metric system only include seven words. Scholars need to know a few more to complete the included puzzles. They match the prefix to the meaning, symbol, and multiple in a series of four increasingly...

Here is part five of 10 soccer lessons, this one focusing on passing and receiving. Open this session with a video of professional soccer players executing a beautiful give-and-go passing situation which leads to a score! It doesn’t get...

Help learners practice their math skills by utilizing the Internet to research a mathematical topic. Your math sleuths will investigate a science or social studies topic from their curriculum and construct a Math Hunt Grid. They create a...

For beginning point plotters, these graphs give a good introduction. They examine a graph with shapes drawn onto it and each vertex labeled. There are 20 total, and scholars write the coordinates of each labeled point. All of these are...

Why are greenhouse gases called greenhouse gases? Young Earth scientists learn about greenhouse gases though experimentation in the second installment of a 3-part series. They use lamps to model radiant energy as well...

Changing the number of neutrons in an atom makes it an isotope, but it does not change the element. Pupils complete logic puzzles, matching isotopes with their unique number of protons, neutrons, and electrons. Either on paper or timed...

Compare sizes of student footprints with those of elephants and sauropod dinosaurs! Upper graders make estimations of the areas of irregular shapes; students use grids to make and explain estimates within low and high ranges.

It's a parade of prefixes! Chemistry scholars identify common prefixes used throughout the sciences using an interactive puzzle series. Learners solve puzzles by pairing the prefixes with the power of ten they represent.
