Signal Flags and Codes

Water, water, everywhere — but will there be enough to drink? Check out these detailed lesson plans to meet NGSS water cycle and CCSS literacy standards in your science classroom. Learners do a close reading of a challenging, poetic text...

Using a simple circuit with the battery representing the brain, future physiologists test to see which solutions conduct electrical "nerve impulses." Enlighten learners with plentiful information on electric signals in the nervous system...

Emerging engineers read about Arduino software and how it can be used. Then they follow a nine-step tutorial to connect an Arduino board to a computer and put it to work! The objective is to code a program that will cause an LED to...

Explore the science of space exploration. Pupils consider technological advances in propulsion, communication, power, navigation, and imaging. They select one of these areas and create a timeline of historical progress that contributed...

Is silicon the same in Spanish? Si. Here is a video that focuses on silicon, including its network solids and network arrangements. It makes connections to solid-state semiconductors, n-type and p-type semiconductors, diodes,...

Genetic code for amino acids always uses three letters. The explanation for why it occurs in triplets makes for a brief statistical video. Examples of single and double letter codes prove insufficient for the number of amino acids.

The amount of pain one experiences is not directly connected to the amount of tissue damage. In fact, it is possible for pain to occur without any tissue damage at all! A video lesson digs into the science behind the phenomenon and asks...

The foot bone connects to the leg bone, but how? Learn about how neurons grow in the proper direction thanks to signalling. Observe what happens when they encounter a repulsive ephrin signal and the correction process that takes place.

Prialt, a prescription pain medicine, is used to treat severe and chronic pain in humans, but is extremely toxic to fish. To understand how Prialt works, class members watch a short animated video that models how calcium channels that...

Students study DNA decoding and protein synthesis. They use the amino acid table to translate DNA, break DNA strands into three nucleotide codes, and translate nucleotides into amino acid protein codes. They research the importance of...
