Here's a great way to prepare for the AP exam format. A PDF file supplies the four free-response questions from the 2017 AP Computer Science A exam. Questions involve identifying and processing the digits of a non-negative integer and...

Use salmon eggs as a cell model for demonstrating the movement of water over concentration gradients. Junior scientists examine the same process microscopically with an onion cell. They use a thistle tube and a semipermeable membrane to...

Students work to create a design that will protect an egg from being dropped from a one story floor. They test their prototype after it is completed. They write clear instructions and link aspects of the design process to the scientific...

Scientists use data to learn about species survival—and your classes can too! A set of four lessons guides learners through a process to draw conclusions about the fluctuations in the population of the Hellbender species. They read...

If you are looking for a great way to present natural selection in humans, look no further. This handout is intended to accompany the 14-minute video The Making of the Fittest: Natural Selection in Humans, which can be found on the...

Make a splash with young scientists as you teach them all about water using this activity packet. Thirstin, a cartoon glass of water, walks children through the water treatment process, teaches them about different sources of water, and...

Dive into an exploration of the water cycle cycle with this simple earth science lesson. After first discussing where rain comes from, young scientists define the terms condensation, evaporation, transpiration,...

What a scam! Middle and high schoolers pose as journalists exposing consumer fraud. In this lesson, they write an article for a magazine using data collected during previous investigations (prior lessons) to defend their findings that a...

Have your young scientists explore a single element of the water cycle and write a report to explain findings. Your class can take their writing through all the steps of the writing process and publish it using a Web-based multimedia...

Almost every ancient culture observed the stars and saw pictures in the patterns. Studying stars allowed them to guide travelers, determine when to plant crops, when to harvest food, and the stories surrounding the images include some of...

Don't be shocked when your class has a blast making their own batteries! Science scholars examine a dry cell battery, then design and construct a wet cell battery. The activity guides them through the parts of a battery, the variables...

Students identify relationships between scientific concepts and their historical roots. They discuss and debate issues of ethics in science, specifically on the concept of genetic engineering and describe the processes of cloning and...

Observe the stages of the water cycle by completing 3 activities. To help understanding of the water cycle your students can observe evaporation, the formation of frost, vapor and water and the process of distillation which is used to...

Engage young biologists with four laboratory activities that explore the fossil record. Learners examine fossil images, a fossil kit, the rock record, and geologic time scale. They even experiment with the oxygen production of an Elodea...

How did the ancient people of Egypt preserve their dead so well that their bodies are still recognizable today? Learn the painstakingly complex process they used for preservation. Young scholars read and summarize a narrative detailing...

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...

Color me green. The fourth lesson in a unit of 15 introduces the class to color images and how to encode color images using binary code and hexadecimal numbers — and they will quickly notice that it is easier to code the...

In this earth science instructional activity, students find the words that help define plate tectonics and the answers are found by clicking the link at the bottom of the page.

Fifth graders study how respiration and circulation are connected.  In this respiratory instructional activity students complete several activities to better understand heart rate and carbon dioxide in the body. 

Extra! Extra! Read all about past and present energy use in a classroom-made historical newspaper. Useful as a cross-curricular assignment between science, history, and language arts, the project is sure to get young journalists...

Students research the process for the preparation of a soup. Students explore the safety issues of food preparation. Students, after presenting their soups to the class, will eat their soups that they have prepared.

Students explore animal habitats.  In this cross curriculum animal survival and writing lesson, students view a website about wild horses on Shackelford Island and discuss ways in which the horses have changed to this...

Mix it up and engage learners in a lesson on music and physical science. Using cups, strings, guitars, and voice, the class will experiment with sound vibration and frequency. They'll use each instrument and fill out a worksheet that...

How are forces and motion important to a swing set? Scholars explore the concepts of force and motion using swing sets. In preparation for their own STEM design project, individuals take surveys and data from peers, complete labs on...
