DNA molecules hold the secrets that make us unique. The fourth of 12 lessons explores the structure of DNA by building candy models. After building the models, young scientists break their models to begin the process of DNA replication....

Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

Examine the nature of landfills through experimentation. Scholars build miniature landfills and monitor changes over a six-week period. Observations allow individuals to draw conclusions about the different types of trash and their...

How do satellites communicate? What types of satellites orbit Earth? Discover and mimic the way satellites communicate between two points in a hands-on activity that has pupils using mirrors, flashlights, and marbles.

Stability is key when building a bridge. Scholars explore the forces acting upon bridges through an analysis of Newton's Laws and Hooke's Law. The activity asks individuals to apply their learning by building a bridge of their own.

Do domed structures have advantages over their less-than-spherical counterparts? Junior architects explore the pros and cons of domes through a design challenge. Teams work together to plan, sketch, build, and test domes created from an...

If a ski lift had rockets, imagine how fast it would be! Scholars let their imaginations take flight as they build models for such a ski lift. Rather than using a rocket, though, they'll use a much safer balloon as the power source.

Small groups investigate plots of land to discover how abiotic and biotic factors interact. After recording their findings, scholars share observations with peers and self-reflect on the learning process. 

Keep playing with those old toy cars! Pupils estimate the number of toy cars in an art installation. The only information they receive is a picture showing the toy cars arranged in concentric rings and the diameter of the overall...

They may not look like it, but sponges are living, breathing creatures! A PowerPoint presentation explains the important characteristics of the invertebrate Phylum Porifera, or more commonly known as the sponges. From their body...

What kinds of birds are common in the area? Young scientists use household supplies to create bird feeders. They then document the birds that come to their feeders by keeping journals. 

No need to wait until Halloween to create a mask. Young anthropologists get involved in the centuries-old tradition of mask and puppet making with the help of an engaging resource that shows them how to craft their own masks or puppets.

Pupils record temperatures at different locations around campus. They examine the results and draw conclusions about how materials and colors affect the amount of heat produced. They also analyze Los Angeles' temperature records over a...

You say that perpendicular bisectors intersect at a point? I concur! Learners investigate points of concurrencies, specifically, circumcenters and incenters, by constructing perpendicular and angle bisectors of various triangles.

Two worksheets are here with 17 complement math word problems. These are not easy problems. Percentages, fractions, metric system problems, and logic problems are all present. Many of the problems require two or three steps to solve....

Students tell about their family heritage by writing a story and illustrating it with a picture of a family item.

Students build ocean floor structures, then map and model an unfamiliar ocean floor. They are introduced to bathymetry and sea floor features, and discover one of the most widely usd methods for studying the ocean.

Learners explore volume in relation to centimeter cubes and other nonstandard units of measurement using small containers. They will use hands-on materials to practice this concept. You will need small objects and containers to set this up.

Early learners rotate to different classroom centers and participate in six activities based on using marshmallows to review concepts learned. They make: marshmallow sculptures (geometric shapes), the shape of mittens using colored...

Act out the African folktale Abiyoyo. Kindergartners listen to the tale and discuss the characters, dressing as their favorite characters in order to retell and perform Abiyoyo using props. They will gain an understanding of...

Launch your class on an exploration of the solar system. Learners construct solar system models to scale and get a better understanding of our place in the vast void of space. This is a great way for them to cement their understanding of...

An engaging and fun lesson on telling time is here for you. In it, young time-tellers listen to the song, "Rock Around the Clock," then use Judy Clocks to practice telling time to the hour and half hour. Finally, using paper plates, each...
