Does the angle of a solar panel change the output? Emerging engineers find out! Demonstrate for your class how they can angle a straw to match the angle of light rays coming from a source. Then turn them loose to experiment with the...

The London Bridge should not have fallen down. And here's why. After a brief history of bridges and the three main types, class members are introduce to the concepts of tension and compression, the two main forces acting upon bridges. 

Students explore hurricanes.  In this weather data interpretation lesson, students draw conclusions about the impact of Hurricane Floyd as it related to weather conditions. Students read and interpret a tide data table, a barometric...

How do one's habits and lifestyle choices affect the environment? Through a short online survey, learners will calculate their own carbon footprints then determine how to reduce their impact on the environment through simple steps, such...

Defy the laws of gravity. A simple activity has learners create a siphon pump for water. The challenge is to get water to flow upwards through a tube.

It's all downhill from here. Scholars model a sewer system using straws and other household materials. They test out their systems using colored water and discover how gravity plays an essential role in sewers.

It's important to know the final destination. Scholars first measure distances in a region of interest using a standard measuring device or by counting steps. They then use an appropriate scale and graph paper to create a map of the...

All types of energy are presented here, with neat pictures and labels to illustrate the technology typically used. Ways of harnessing the energy most efficiently are discussed, and good examples provide starters for further research....

Students participate in an investigation in which they compare a polyethylene bag designed for recycling or disposal with a polyethylene food storage bag. Students use hexane to determine the differences between the low density...

Students use a light microscope to observe the organisms living in a sample of ocean or fresh water. Students create a drawing of the organisms that they observe. Students then discuss the different body plans of the organisms and the...

Wow! Colorful and simple, these 160 slides introduce the various forms of energy, along with a relevant image. Some of the images are animations, which help beginning physical scientists to visualize the flow of electrons or energy! This...

Friends arrive at the farm and aspiring agronomists help the farmer to grow what the friends want. With adorable animation and charming background music, little ones practice virtual gardening and farming while developing cognitive...

Pupils interpret maps and graph data related to volcanic ash. Then they analyze the importance of wind speed and the dangers of the ash to both life, air temperature, and technology. 

Does molecular mass affect the rate of diffusion? The simulation allows scholars to experiment with diffusion while varying the molecular mass and temperature. The timer automatically stops when a certain point is reached, making it easy...

Animal reproduction in sheep and cattle is explored with the help of Punnet squares. Scholars employ tools using probability to conclude the color of wool a sheep's offspring will have. Acting as animal geneticists, pupils then take...

Scientists need to figure out how to measure interplanetary magnetic fields, but the magnetic field of the spacecraft is interfering with their readings. Scholars attempt to solve the problem that has perplexed NASA scientists for years.

How many noodles long is your classroom? Find out when engineers of all ages explore measurement through the use of pool noodles. With the noodles pre-cut to certain metric lengths, the activities could be used to introduce the metric...

Three activities make up an introductory lesson designed to create a strong foundation in comparing fractions to decimals and exploring and building decimal models. Pupils brainstorm and complete a Venn diagram to show how decimals and...

Animals and plants develop relationships and rely on each other to survive. Pupils learn more about symbiosis through a video, a hands-on matching activity, and a game. They differentiate and describe each type on a written evaluation.

Young scientists learn about DNA replication through a video and model creation. They answer analysis questions before exploring the role of mutations and then complete a summative assessment.
