Ice Cores: Modeling Ice Sheets
Ice cores provide scientists with knowledge of historic melt layers, air temperatures, greenhouse gases, and climate stability. Scholars work in groups to build layers representing snow and ice over thousands of years. Then, groups...

Drawing Diatoms like Ernst Haeckel
Why do scientists rely on drawings rather than just photographs of their research studies? The lesson introduces drawings of microscopic organisms and the importance of accuracy. Young artists draw organisms and learn why focus and...

Permafrost Thaw Depth and Ground Cover
The thaw depth of tundra creates a positive feedback loop with both global warming and the carbon cycle. Scholars sort photos and develop a hypothesis for ground cover and permafrost depth. Then they review the data and measurements...

Science in Antarctica
PolarTREC brings polar researchers and educators together to benefit both science and education. Pupils select one research project in Antarctica to explore and present to their peers. Scholars polish research and presentation skills as...

Bioaccumulation of Toxins
In 2015, Peter Cook found that sea lions with high levels of exposure to toxins suffered permanent brain damage if they survived at all. Scholars learn about the accumulation of toxins at various levels of the food chain. Using...

Touring the Poles
Would you want to vacation in the Arctic or Antarctic regions? Scholars research both regions and produce a travel brochure trying to convince tourists to visit. The project focuses on the geography, climate, flora, fauna, and indigenous...

Resistor Simulation
Many scholars struggle to picture electrons traveling in a circuit but understand water going through a pipe. The simulation compares circuits to water pipes. It walks pupils through four levels of questions, allowing them to switch...
CK-12 Foundation
Capacitor Simulation
The camera flash works based on a simple circuit, but why does it require a capacitor? Scholars work through two levels of simulations related to circuits and capacitors. The pupils first use a simple circuit with a battery,...

Blood Types
Does your blood type matter? The video explains the four main blood types and the importance of knowing blood types when performing transfusions. The interactive reviews the information with a quick graphic organizer and questions.

Natural Selection: Of Seasons and Species
Do predators look for different things in different seasons? The quick interactive shows how some species survive longer in one season than another based on the conditions. The challenge questions encourage pupils to demonstrate that...

Natural Selection: Natural Disasters
Can natural disasters alter natural selection? The interactive explores this concept with mice living through a forest fire. As the environment changes, the camouflage also changes. How does this one disaster impact future generations?
CK-12 Foundation
Passive Transport
Some molecules move through a membrane with diffusion while others require protein channels. The video and interactive discuss both types of passive transport. Challenge questions allow scholars to demonstrate their understanding.

Meiosis
"We Are Never Ever Getting Back Together" makes the perfect theme song for meiosis. The simulation encourages scholars to move the chromosomes and chromatids to properly illustrate the meiosis break up. Multiple-choice questions allow...
CK-12 Foundation
Cellular Respiration: Can Photosynthesis Be Reversed?
Cellular respiration and photosynthesis relate closely, but many don't realize how. Scholars drag and drop the reactants and products to the chemical reactions for both processes. Then they answer three multiple-choice questions.
CK-12 Foundation
Power and Efficiency Simulation
How much energy in Jewels does it take to tow a car up a slope? Scholars explore different values of both kinetic and potential energy to answer that question. Through multiple levels, the difficulty increases — as does your young...
CK-12 Foundation
Oscillations Simulation
What makes a swing go back and forth like a pendulum rather than going all the way around? Scholars use the simulation to explore pendulums and how they work. They vary the weight, length of the rope, and even gravity in various trials.
CK-12 Foundation
Hockey Simulation
Do you understand the science behind hitting a hockey puck to control the direction it moves? Pupils experiment by telling a hockey player how to hit the puck so it moves in a circular direction. Through manipulating the velocity and...
CK-12 Foundation
Cannon Simulation
Fire in the hole! Thrill your classes as they see what it's like to fire a cannon ball. Scholars practice aiming a cannon ball by altering first the firing angle, then the velocity, and finally both simultaneously. Can they discover the...
CK-12 Foundation
Electric Fields Simulation
Can you get the puck into the goal using only electric charges on the ice? Scholars experiment with electrostatic forces as they determine which charges pull the puck and which repel it. Multiple levels reinforce different related...
CK-12 Foundation
Electric Ice Sheet
Tommy is trapped on an ice bridge and needs you to balance the charges so he doesn't fall into the icy water! Scholars apply Coulomb's Law, which relates to both the strength and the distance between charges. They work with these two...
CK-12 Foundation
Energy Conservation Simulation
Does the amount of a roller coaster's energy change as it goes along the track? Scholars investigate when a roller coaster has potential and kinetic energy. They observe the changes as it goes up the initial hill follows it throughout...

Third Law Simulation
Keep calm and use the force! Joey pulls a cart and scholars adjust the force required to control the movement. Through simulating different scenarios, participants learn about Newton's Third Law. It includes analysis questions throughout...

Free Body Simulation
To show the magnitude and direction of all forces acting upon an object, scientists use a free body diagram. This simulation serves as an introduction to free body diagrams allowing scholars to build their own. Pupils select the proper...
