The difference between atomic mass and atomic number can be confusing for some young chemists. Help your class better understand the concepts by allowing them to sketch an atom on paper and then discuss their experience. Upon completion...

What's the likelihood of your class understanding probability maps? Young scientists explore the concept using a virtual dartboard in an interesting simulation. The darts establish a pattern around the bull's-eye, which provides a visual...

Molecules to the Max! refers to a movie released in 2009 about the world of atoms and molecules. A helpful discovery guide provides five posters on science topics typically covered at the middle school level. It also explains the...

Students read and discuss an article about carbon dating, then participate in a hands-on lab to discover how carbon dating works. Students also write a letter to a friend explaining the process, and how archeologists use the process to...

This is a tremendous overview of the tiny atom. Journey through the history of human understanding of this basic building block of matter. Examine each of the sub-atomic particles in detail: neutrons, protons, electrons, quarks. Peruse...

The human body contains more than 200 types of cells, and plants contain many other unique types of cells. While a huge variety of cells exist, they appear to have very similar structures. A detailed presentation describes the structure...

Young scientists take a trip into the microscopic world of cellular biology with this practice exercise. Given pictures of different organelles, students must correctly identify specific parts of each cellular structure to demonstrate...

Transcription means a written copy but how can DNA write a message? The video explains transcription and translation as they relate to DNA and RNA. Then in the interactive, scholars practice base pairing and answer analysis...

Energize the cells of young biologists with an edible life science activity. Engaging students in exploring the inner workings of plant and animal cells, this activity involves using colored jello and various sweet and...

How do reverse transcriptase inhibitors work? Young virologists examine the function of azidothymidine, a drug doctors use to treat HIV patients, during a hands-on modeling activity. Groups create a strand of DNA from an HIV RNA strand...

Students explore scientific theories and the works of scientists.  In this chemistry lesson students develop a timeline  that shows how scientists work was built on the ones before them. 

Young scholars use analogies to show the relationships among cell, nucleus, genes, chromosome, ribosome, replication, mitosis, transcription, translation, DNA, RNA, amino acids and proteins, genotype, phenotype, and genetics vs....

Learners observe slides of cork cells and discuss the use of microscopes. They view a power point presentation on "Looking Inside Cells" and take notes aligned with the PPT presentation. They collaborate with a partner to create an...

Get up close and personal with human cells with this lab worksheet. Learners use a microscope to examine their own cheek cells, drawing diagrams of the cells and identifying the parts when they have focused in on a visible specimen....

Fifth graders explore volcanoes and the rocks they produce using the Internet. The lab portion of the lesson prompts young scientists to compare and describe igneous rocks. Next, they critique a pair or more of...

Why are we here? Well, if you happen to be a Golgi body, the answer is simple! Young biologists embark upon a journey through the tiny world of cellular organelles with an engaging lesson from the K20 Center. The activities open with an...

Young geologists explore volcanoes with a series of engaging geology activities. First, they learn the difference between magma and lava before coloring and labeling the parts of a volcano. During the lab, individuals watch a...

After learning about P waves and S waves, fifth graders view the intensity of earthquakes by examining seismographs and images of earthquake damage. Young scientists then forecasting future quakes by analyzing data about...

Examine earthquake intensities and ways to measure an earthquake through the comparison of the Mercalli and Richter scales. After completing the pre-lab worksheet, fourth graders compare high and low intensity quakes by testing...

Start this lesson with a bang! The eighth in a 13-part series of lessons explains the origin of elements beginning with the Big Bang Theory. The reading describes the formation of elements hydrogen through uranium.

In this cell worksheet, students identify the function of 4 different parts of a cell, complete 4 word connections, and complete a word puzzle about cells.

This quiz just looks neat! It has two cell diagrams for biology class members to label. They also describe the function of each organelle. A prokaryotic and eukaryotic cell are displayed for them to compare, and then they fill in the...

This PowerPoint is a comprehensive review of all the facts related to an atom's basic structure and function. What makes this unique is that it is geared toward an audience of junior geologists. After introducing the periodic table of...

The ten slides in this presentation make a consice introduction to the halogen group of the periodic table of elements. The location of the group is displayed, and then the characteristics of the different halogen group members are...
