Lead your young scientists into an exciting world as they participate in a role play and experiment focused on proteins and DNA. After researching the Central Dogma of Biology, individuals or groups participate in a classroom...

Here is a copy of a past national challenge exam that you can use in your general chemistry course as a unit or semester review. Sixty multiple-choice questions query learners on properties of matter, stoichiometry, reactions, and...

Match my cereal sequence. Pupils view a sequence made by colorful cereal rings and create copies of it. Learners must either remember or write down the sequence to transport the code to another location. Scholars replicate the cereal...

This is your brain on drugs ... literally! Your neuroscientists-in-training examine the evidence of drug use on the human brain and how neurons change their connectivity when altered by drugs. They then work together to create testing...

Electricity travels at the speed of light, 186,000 miles per second. Through a simulation, classes see how the structure of energy bands in crystals of atoms determines how materials conduct electricity. Participants can change the...

What makes a watershed? What are the natural and human features of a watershed? How do human features affect watersheds? Where can I find my local watershed? These questions are thoroughly explained in an informative watershed interactive.

String up a message. Pupils string together colored beads to code a word or short phrase. Each color represents one of the four DNA bases. Using a combination of three bases, learners create an amino acid that stand for each letter of...

Sixty multiple-choice chemistry questions make up this comprehensive exam used for the 2001 US National Chemistry Olympiad. Every topic that you would expect to approach in a general chemistry class is queried on. You could easily use...

High schoolers explore electrical resistance through various experiments. In this physics instructional activity, students calculate resistance using a mathematical formula. They explain how colors identify the resistance value of a...

Pupils pose their hypothesis, they ready their instruments, then record their observations. This is the science of sound activity. They move through 5 stations, each focused on a different element of aspect of sound. Check this activity...

When it comes to the origin of the human species students are full of misconceptions. Clear up the hominid confusion with this evolutionary activity focused on assisting students in understanding prehistoric man and his family tree....

Don't lose your marbles — you'll need them for a lesson on neurotransmission. Young scholars build a neurotransmission model using marbles, beads, rubber bands, string, and other elements. After studying specific neurotransmitters,...

It's electric! Young anatomists use Virtual Neurons software to build, control, and analyze complex nerve circuits within the body. Colorful and packed with content, class members enjoy interacting with the nervous system...

Use food coloring in electrophoresis. The last segment in a four-part series mimics DNA fingerprinting by using chromatography. Teams conduct chromatography on food coloring to find colors that use similar pigmentation in their makeup.

A cell of another color is still a cell. Pupils color a cell to identify its structures in the fourth segment of a seven-segment series. Groups work together to build a three-dimensional cell membrane segment, which is combined with...

A case study of Seattle, Washington permits class members to compare and rank how different areas of Seattle are impacted by environment burdens. Groups investigate different zip codes, collect data on five categories, and color-code a...

Students explore the pros and cons of forest fires. In this science lesson, students research the ecological implications of forest fires. Students record their findings in journals and compose a persuasive e-mail to government officials.

Addiction is a big deal! Playing a game of cards helps learners understand the concept of addiction. Through their analysis, they examine the potential for addiction and how it varies for each individual.

Explore the world of motion and force with an activity for kindergarten and first grade. After determining how people can make balls or bikes move slower, kids use a cardboard tube and a marble to experiment with motion and speed. A...

Students explore a map of the worldwide distribution of blood types and observe the patterns.  In this blood type lesson students conduct a lab and determine the geographic distribution of the different blood types and determine a...

For this wires worksheet, learners answer 16 questions about types of electrical wires, their gauge or sizes, the ampacity of wires and conduit.

Students find the mass of the top quark. In this physics lesson, students create a vector diagram from a given set of data. They discuss their calculations and findings in class.

How many people really recycle recyclables and how do they feel about it? High schoolers create a survey to find out. Once they agree on what questions to include, they each interview four people outside of the classroom....
