Get your class to take a closer look at DNA. Pupils conduct research to determine the methods used by scientists to analyze the molecular structure of DNA. The class members investigate different types of molecular imaging along with gel...

Thirty percent of the world's oxygen is produced by rainforests found throughout the world. Seventh grade learners explore the processes of photosynthesis and respiration through 10 days of labs, manipulatives, and discussions. They...

Get some laparoscopic training without the pain with an activity that challenges class members to find out what it is like to perform laparoscopic surgery. Teams perform three different tasks and quantify their performance. The...

When you have to flow, you have to flow. The lesson introduces class members to microfluidic devices and their uses in medicine. They watch a short video on how the diameter affects the rate of flow. The worksheet has individuals...

Nothing flows like J-E-L-L-O! In the final portion of a four-part series, pupils create scale models of microfluidic devices out of gelatin and bendable straws. They use their devices to test various flow rates in the delivery of...

Let's get a closer look at DNA and other molecular structures. The first lesson in the series of four introduces a variety of imagining techniques that engineers and scientists use to visualize molecular structures. The resource presents...

Photosynthesis was discovered in the 1770s, but chemosynthesis wasn't discovered until 1977. While many have performed an experiment to show how photosynthesis works, the activity allows pupils to observe chemosynthesis. Scholars set up...

Where does the pop in pop rocks come from? An engaging activity asks scholars to measure the amount of carbon dioxide in a package of Pop Rocks candy. Learners dissolve the candy in water and use the solubility of CO2 to determine its mass.

Learners explore atomic measurement in the first activity in a series of 36. Through readings, activities, and questions, classes review standard SI units, learn about Avogadro's constant, and use it to help them calculate moles. They...

Develop a model of a wastewater treatment center. The last activity of the unit has pupils mix a lake water sample into a tank of water containing fertilizers. Over time, the algae from the lake water grows and removes the nutrient-rich...

What's in soil? Young scientists study the pH levels of soil from their school yard. They observe the land and area the soil came from to decide if location has anything to do with acidity level.

Super scientists tests the toxicity of water using radish seed bioassays. Over the course of five days, scholars observe the germination process of several radish seeds, looking closely at their roots to determine the level of toxins...

Explore the scientific method of classification. An interactive activity asks learners to create a classification system for a group of objects and develop a flow chart to communicate their systems. In addition, individuals use a...

Small but mighty! Learners explore the role of microbes in a healthy ecosystem. An engaging lesson asks pupils to design an aquaponics system that demonstrates that healthy microbes are necessary to maintain the ecosystem.

Experiment with optical resolution using an inquiry-based lesson. Young researchers calculate fellow classmates' optical resolutions. They apply the information to understand the inner workings of optical instruments.

Does it feel a little humid in here? Learners assume the role of water vapor in the atmosphere as they explore the differences between warm and cold air. They roll dice to determine their level of energy, which determines if they...

Scholars become part of the cycle of matter with a reader's theater that showcases producers, consumers, decomposers, and the sun. A diagram and discussion concludes the learning experience and enhances comprehension. 

What a bright idea! Young scientists conduct an experiment on flowers to finish the last of a six-lesson unit on Cells. Putting the stems into dye-injected water and leaving it overnight results in flowers that glow. This is to simulate...

See what you cannot see by getting a little creative. An intriguing lesson has learners use lasers to explore X-ray diffraction. Given a box with unknown structures, they shine a laser through the box and interpret the results....

Jell-O® can help model the transmission of light through fiber optic cables. Young scientists use the jiggly dessert to make a waveguide to transmit a laser beam from one point to another. Their models help them learn the function...

Help your classes feel like they can walk on water! An engaging inquiry-based lesson has young scholars experiment with different surface coatings. They make observations about their properties and how they relate to the surface tension...

Are viruses living or non-living? According to the presentation, they are both and neither. Clearly, this requires clarification and an in-depth look at viruses, viroids, and prions. Young scientists learn about the history, structure,...

Water covers more than 70 percent of Earth's surface. Scholars learn about both freshwater and saltwater biomes in a simple presentation. They compare and contrast the differences in oxygen levels, food sources, and sunlight to better...

Some genes link to others that have implications for inheritance. A set of resources lead pupils through the history of this discovery. They explain how chromosomes recombine and which parts are more susceptible to this linkage....
