New ReviewGet the code right. A detailed resource provides pupils and teachers of computer science courses with released items from the 2008 exam. Questions range from studying code in a case study to creating code to perform specific tasks....

How did early scientists arrive at the notion that everything was made of atoms? Meet the Presocratics during the second installment in an engaging History of Science series. Viewers discover how these pioneers developed a model for...

Why do some people still question climate change? Discover the components of consensus with a video from a well-written science playlist. The narrator guides viewers through the process of reviewing climate publications, how exclusive...

Five women of different ethnicities and living in differently colored houses own different pets, drink different beverages, and work in different professions. Who is who? Solve a logic puzzle that provides 14 clues about connections...

All teacher workrooms contain a coffee maker, therefore all teachers must be addicted to coffee. That sentence represents a logical fallacy (although it may be true from some), a topic the seventh installment in the 24-part Writing the...

Explore the process of inductive and deductive reasoning. A collaborative lesson has some groups apply an inductive approach and others a deductive approach. Through class discussion, scholars compare their processes and discuss...

Do your young scientists love a good brain teaser? A video from an extensive physics playlist introduces a creative way to work those critical thinking skills. Watch as the host works through the scenarios that involve logic, statistics,...

Indirectly, it is a good proof method. A segment of a playlist on geometry introduces a way to prove geometric and algebraic statements. Using a general examples, the video shows how to develop an indirect proof.

Is it true? Use an inquisitive resource to find the truth of related statements. Using short-hand notation, the video shows how to write the converse, inverse, and contrapositive of a conditional statement. The segment a larger geometry...

100 floors, 100 Faberge eggs, one thief, and one escape vehicle. Young logicians put together what they know to determine how a thief can safely drop a fragile Faberge egg out a window of the city museum into her waiting truck and escape.

If you go back in time to kill your grandfather, would you have been born? The lesson narrator uses this grandfather paradox to explain the concept of quantum superposition. He shows how the superposition of two states solves the paradox.

Examine cause and effect through the lens of physics. A video lesson describes how the reality of cause and effect does not apply to physics. Rather than following cause and effect, particles simply change in a predictable pattern.

ALU, what are you? Young computer scientists watch a video to learn about the Arithmetic and Logic Unit (ALU) in the fifth video of the series. They use logic gates to represent each component of this unit.

A fast-paced video offers examples of proof techniques. It covers logic, bijections, applying previous math results, mathematical induction, and proofs with pictures.

Although the methods are all scientific, forensic science was started by police officers rather than scientists, who relied on observation and common sense. Young detectives use many tools to solve crimes around the school in a...

If there is a conditional statement, then there is a hypothesis and conclusion. Pupils learn how to identify the parts of conditional statements. Class members continue to work with conditional statements and rewrite them in their many...

The Three Gods Riddle has been called the "hardest logic puzzle ever." Introduce viewers to the problem with a video that challenges scholars to find the solution.

Young computer scientists continue programming with while loops by creating a program to simulate coins flipping. 

Bring your pupils in the loop with while loops. Scholars learn how to modify conditional statements to produce while loops in the 14th lesson of the series. They use flowcharts to understand loops and then program some examples of loops.

Scholars apply previously learned skills to create a functional computer program. They produce a digital assistant incorporating string commands and complex conditional logic.

Scholars explore compound conditional logic and learn to use the Boolean operators AND, OR, and NOT within conditional statements by incorporating these operators to improve a previously created app.

On one condition ... explore how to use conditionals within conditionals. Scholars apply conditional statements to improve upon the app they built during a previous lesson. They also learn about nested conditionals in the 11th lesson of...

Explore decision-making logic in programming computer games. The 10th installment of a 21-part unit teaches scholars how to apply conditional statements and Boolean expressions. They use these concepts to create a "Guess My Number" game...

Math enthusiasts and riddle gurus are sure to love a mind-bending puzzle involving a king, a scale, and a counterfeit coin. Middle and high schoolers work through a video that describes a mathematician's challenge to find a false coin in...
