Middle-schoolers still enjoy playing with bubbles! In this series of eight laboratory activities, science learners explore convex and concave surfaces, angles, gas laws, buoyancy, density and more! 

Students compare kelp and land plants. In this sea plant lesson plan, students look at the role of algae in aquatic environments. They research the properties of kelp and explore seaweed. 

A cute folktale from Bali tells the story of Gecko, Elephant, and Buffalo, and Gecko's struggle to sleep. After reading Go to Sleep, Gecko, learners focus on comprehension questions, singing and learning about geckos, building...

Should we continue to spend money on nanotechnology? Groups engage in a problem-solving unique process around the newly emerging research field of nanotechnology. In order to propose a solution, the groups must research nanotechnology...

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...

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...

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...

Students observe how to distinguish observations form inferences.  In this examining inferences instructional activity students list observations relating to the activity and discuss the importance of them. 

In this human cells worksheet, 7th graders complete a science experiment using human cheek cells. Students sketch the cells at high and lower power and label the cell nucleus, cytoplasm, and cell membrane.

Students investigate different types and their parts. They differentiate prokaryote and eukaryote cells and create a venn diagram displaying differences or similarities. Students write ten similes related to the cells and parts of them.

In this detecting disease worksheet, students will review the different tools scientists use to identify diseases including the steps of Koch's postulates. This worksheet has 14 fill in the blank and 4 short answer questions.

Young scholars practice calculating density and examine examples of the physical characteristics of soil. They solve a "crime" based on the evidence and laboratory investigations.

Students study viruses and bacteria that can contaminate vegetables. They examine how vegetables can be preserved and what farmers might do to keep vegetables safe. They examine with pickling as a way to keep vegetable preserved safely.

Students study the history of DNA and how to extract it. In this genetic lesson students complete a DNA experiment using bacteria.

Ninth graders design and conduct an experiment. They evaluate other's experiments. Students describe relationships between biological systems and the environmental contaminants. They work as a team to solve a problem.

Ray Bradbury does it again, providing a story full of symbolism and interest. After your class reads "A Sound of Thunder" and studies the difficult vocabulary, quiz them with this sheet. Example words include aurora, expendable, and...

Students investigate how mutations lead to changes in cell structure and function. They construct an oligonucleotide, identify a protein sequence, design a step-by-step mechanism of how they think cells repair damaged DNA, and prepare...

Students examine a PowerPoint production on molecules. Then they construct their own molecule and define what an atom, molecule, and matter is. They make a H2, HCI, and an H2O molecule. Finally, a drawing to accompany the actual model is...

Help your scholars get a grasp on the chronology of the Industrial Revolution with this "Innovative Inventions" worksheet. They discover what year various items were invented, and then create a timeline placing each invention and...

Explorers set up Windogradsky columns with local mud so that they can culture microorganisms. After three and six weeks they make observations of the mud and the organisms growing in it. In this way they observe succession and relate...

Multiple choice, fill-in-the-blank, short answer, and matching questions are all here in a multi-page worksheet or quiz. While the formatting leaves a little to be desired, it would take just a few minutes to change the handout into a...

High schoolers take measurements of the distance between the objective and the slide when in focus with each objective. They determine the diameter of the field of view at each power in order to determine the size of the cells being...

Students explore the concept of anti-counterfeiting measure.  In this economics lesson, students use science equipment to discover anti-counterfeiting designs.  Students then explore other denominations of bills.
