Young scholars explore DNA recombination. In this biology lesson, students observe the growth of microscopic species. They predict the phenotype of the transformed colonies.

Students explain and understand the circulation of air in the atmosphere. They identify that energy can be carried from one place to another by heat flow or by waves, including water, light and sound waves, or by moving objects. ...

In this building your own cell worksheet, students identify cell vocabulary and facts, and create posters of a labeled plant cell and an animal cell. In this fill-n-the-blank and posters worksheet, students provide twenty-three answers.

Students determine the approximate time a cell spends in each phase of mitosis by counting cells in each phase from a prepared slide. They use a few simple calculations to estimate how long cells spend in each cycle in the body.

Ninth graders participate in experiments to investigate the the effects of nicotine, caffeine, aspirin, alcohol, and sleeping pills on the heart rates of Daphina. They describe the relationships between common drugs and heart rates....

Students define reflection and refraction. In this Physics lesson, students compare a variety of items to find properties of reflection or refraction. Students record their findings.

Students examine the cell coats (matrix) of chondrocytes and fibroblasts and observe these cells actively exclude particles which are released around them. They observe the function of the cell membrane as a gatekeeper as it prevents...

Eighth graders, after creating a Venn Diagram comparing/contrasting animal and plant cells, writing ten similes describing cell types, or drawing a colored diagram of a cell, list cell types as well as describe and label cell parts. They...

In this reproductive system worksheet, high schoolers compare specimens of rat ovaries and testes. They complete 5 short answer pre-lab questions, follow an 11 step procedure and answer 5 analysis questions.

Students study the biodiversity in pond water. For this biodiversity lesson plan, students observe 3 samples of pond water using a pond water identification sheet. They record their findings and identify the organisms they find, the...

Students investigate cells. They discover what cells are, where they are found, what they do and what they are made of. They construct a giant cell that is posted on the bulletin board.

Even middle schoolers still enjoy experimenting with bubbles! They execute a series of experiments enabling them to distinguish between convex and concave surfaces, explore the properties of buoyancy, surface tension, and density,...

What an exciting lab experiment to conduct with your high school chemistry class! Crystals are formed naturally in the environment. However, allow your blossoming chemists to create their own unique crystals using alum and...

Hands on science is the way to go! Learners conduct a lab experiment to help them explain how plants make food through photosynthesis. They test for the presence of starch in leaves using iodine solution and identify the basic things...

The many aspects to consider in Marine Fisheries are covered in this very detailed PowerPoint.  There are a large number of slides dealing with both the conditions to consider and terms regarding fisheries. It also covers the laws,...

What variables change heart rate? Young scientists observe the beating heart in Daphnia to understand these variables. They make changes in temperature, chemicals, and other factors as they graph the heart rates. Analysis questions help...

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

Students observe the effects of eutrophication and determine why it is harmful to aquatic ecosystems. They create mason jar ecosystems to observe the growth of algae in pond water. In addition, they observe the effect of introducing...

Investigate the properties of rocks and minerals through a rockin' hands-on activity. Learners test rocks for various properties and, using a guide, attempt to identify different samples. They use various properties including hardness,...

Compare various types of biological diversity in a coral reef and calculate a numeric indicator that describes the diversity found in coral communities. Your class can work in groups to look at the abundance and distribution data of...

Design a public information campaign to improve understanding of the coral reef crisis. Read about and discuss the biology and threats to the coral reef. The class creates a public information program about the problems facing the coral...

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...

Students build plankton models and compete to see which sinks most slowly. They write, or orally present ,the adaptations they incorporated to slow the sinking rate of their organisms. Race results can be grounds for some prizes!
