In a previous lesson, learners build an ammeter. That ammeter, or a pre-made one, is required in order to carry out this lesson. The objective is for lab groups to design a way to connect solar cells that can recharge a battery. Basic...

You can breathe easily now that you've found a winning resource. Young biologists learn about the process of cellular respiration, primarily through teacher-led discussion and instruction. They also consider the concept of...

Technology tutees read a description about coconuts and how they are used to make biodiesel fuel. Note that the link to the article does not work, and the article does not appear to be available online. There are, if you look for one,...

Young scholars discover how capacitors help store data.  In this computer science lesson, students investigate how capacitors can store an electronic charge, eventually helping computers store data.  Young scholars create their...

Sometimes low, sometimes high, but always in motion! Explore Earth's tidal system in the 10th interactive in a series of 13. Engaging life and earth science students alike, the versatile resource demonstrates cause and effect between...

While AP Physics 1 counts as an introductory college Physics course, AP Physics 2 counts as a second-year college Physics course. Help scholars prepare for this more advanced college-level test with questions from previous assessments...

Practice makes perfect! A released AP® exam gives scholars practice with the high level of expectations of their exams. The exam consists of four questions from 2000. Questions ask about endangered species, recycling, alternative fuels,...

Salt is the go-to material when people need to melt ice—learn the chemistry behind its effectiveness with an interactive lesson. Pupils watch a short narrative and then explore the concept through a simulation. Young scientists...

Can you lift a piano into a truck? Simulation allows scholars to explore the relationship between force, ramp length, and weight. Pupils control the variables of truck bed height, ramp length, weight of piano, and the number of friends...

In a simple circuit, does electricity start instantly? A simulation encourages thinking about the flow of electrons at a microscopic level. Pupils control the voltage, resistance, and switch in order to observe the change in both ideal...

How can a pan flute sound one note while we hear a chord? The simulation explores sound waves, vibrations, and harmonics at the molecular level. Scholars control the pipe into which air is being blown, the length of the pipe, and which...

Water quality testing often reveals interesting facts about the local environment. Scholars respond to several AP® questions highlighting topics such as air pollution, water pollution, and the spread of disease. Each question requires a...

A number of diagrams are presented. These illustrations are meant to represent certain levels of energy, the complexity of some reactions, and the production of substances that are essential to our body.  Although the information...

There are some really nice diagrams and facts regarding the atmosphere and regulation of energy levels in this PowerPoint. It would be wise to double-check some of the details, but these slides would provide a nice visual recap of...

Students examine the definitions of biomas gasification and generate their own biomass gas.  In this renewable energy instructional activity students collect gases and roast a marshmallow. 

Planning an elementary science unit has never been simpler! These twelve lessons guide young scientists through an exploration of simple machines and their many uses in the real world before asking them to apply their learning...

It is impossible to cool down a glass of water by adding ice. Young scientists explore heat transfer through videos, experiments, and interactive games. They quickly catch on that the water melts the ice and things aren't always as they...

The 20th activity in a 21-part series connects the wind data and expectations of a turbine to whether such devices should be built in your area. Scholars begin with estimating the wind potential at school by using long-term climate...

For this Bohr model diagram worksheet, students draw the Bohr diagram for 6 elements. They show the number of electrons in each energy level and the total number of protons and neutrons in the nucleus.

In this chemistry worksheet, students complete the table for each element by writing the electron configuration of the element and giving the values of the four quantum numbers. They also create an energy level diagram for their element...

Learners examine the role photosynthesis plays in plant survival.  In this renewable energy lesson students document their observations and analyze and interpret their results. 

Students discover ways to conserve energy in their homes.  For this energy efficiency lesson students analyze a set of data and design a solution that results in higher energy efficiency.

It's a gas. Middle schoolers build a biogas generator following the directions in this resource. After a few days of observation, they demonstrate that the gas given off by the decomposing manure is flammable. The activity concludes as...

You're only 10 minutes late? Do you know how much the universe has expanded in those 10 minutes? Scholars graph supernovae based on their redshift and see if the results verify Hubble's Law. If it does confirm it, the universe is...
