Evolution occurs though change over time, but can it go any faster? Scholars speed up the process of evolution and observe a simulation of 20 blue organisms fighting for survival. A graph displays the changes in phenotype over time. By...

Radio waves are all around us! How do they transmit sound? Using an interactive, scholars examine how songs travel through the air. The resource explains the process from the radio station, to signal towers, to the radio unit. A look at...

Is the structure of a clam really as simple as it seems? Young scholars explore the anatomy of the clam in an engaging lesson presentation. The lesson highlights the digestive process of the clam as well as how it moves and what it does...

Based on current scientific knowledge, all cells come from preexisting cells. Scholars learn about cell division, cell replication, mitosis, meiosis, and more with a PowerPoint. It describes the differences between prokaryotes and...

Brown rice contains vitamins B and E, while white rice lasts longer in storage. The availability of rice around the world makes it a great candidate for genetic engineering. Scholars apply their knowledge of genetic engineering to solve...

Everything evolved from a common ancestor, but how did modern plants and animals develop so many more genes? Scholars use an online interactive to learn about the process. They begin to understand common genes with an animation, multiple...

Extracting oil is more difficult than many think! Learners work together and get hands-on as they represent oil companies drilling for oil by simulating oil extraction using beans. They identify the challenges faced in using...

The spread of an infectious disease can be a complicated process. Using a game approach, learners reenact the spread of the West Nile virus. They learn the need for the vector in transmitting the disease and how different organisms react...

When studying locations of specific species, interesting patterns emerge. Young scholars discover this as they plot the location of specific species on a group of islands. Patterns emerge as they identify the Wallace Line. They then...

Save the class from a lack of engineering experience. An engaging STEM activity has learners work in groups to design a lifeguard chair out of masking tape and index cards. They build and test prototypes, all while learning about the...

Don't be a drag. Learners work in groups to design boats that move slowly. The provided reason for the activity is that a fish caught on a fishing reel is pulling the boat, causing it to move too fast. The STEM activity teaches the class...

Biodiversity refers to the variety of animal and plant species in a specific habitat. With a collaborative activity, the habitat becomes a page from the white pages, and the species are the surnames in the book. Learners calculate the...

How is solar energy able to move wind and water to control the climate? Scholars explore the concept of solar energy in the first of 10 activities in the Discover Your Changing World series. They follow instructions to build homemade...

Follow the life of an apple from harvest to the consumer. A three-part lesson describes the different steps to get an apple from the farmer to your kitchen and the approximate waste that happens at each step. They discuss the process and...

Journaling is a great tool for processing information. Budding scientists build their own butterfly journals from their observations in a butterfly garden. The lesson challenges them to identify different stages of the life of the...

Pigmentation of leaves is important in plant processes. Scholars use chromatography to create a better picture of the pigmentation in an assortment of leaves. They share their results to make comparisons between different plant species.

Some living things go to extreme measures to avoid the cold. A three-part activity guides learners through the migration of the monarch butterfly. After studying the life cycle of the monarch butterfly, pupils learn the process of...

Forming ethical arguments is sometimes a complicated task. Guide classes through a process for forming and presenting ethical opinions. Learners consider the views of all stakeholders on the impact of farming on the environment and the...

The state of molecules is changing. Young actors and actresses perform the process of phase change in front of the class. They assume the roles of water molecules and, as a group, show how the behavior of the molecules in the solid,...

Rocks hold evidence of Earth's past. A three-step guide describes the process of creating a rock collection. It provides a data collection sheet to make notes about each sample.
