High schoolers investigate the enzyme catalase. In this enzyme lesson plan, students observe a normal catalase reaction, they observe liver tissue, potato, chicken and apple for the enzyme catalase and they study the effects of...

High schoolers investigate blood moving in the fin of a fish. In this blood circulation lesson plan, students use a goldfish wrapped in water soaked absorbent cotton, placed in a large petri dish, then placed until a lighted microscope...

Students build an understanding of the properties of liquids and research the immiscible properties of different milks through group experiments. In this immiscible liquids experiment, students investigate what happens when certain...

In this relationships and biodiversity activity, students investigate the relationships between 4 plants sample using 7 different tests. These include looking at structural characteristics of the plants, seeds and stems, using paper...

In this scientific investigation worksheet, students use "magic tubes" to make observations, hypothesize, study variables in experiments, write procedures, and draw conclusions.

Eighth graders investigate chemical reactions to produce polymers. In this polymers lesson plan, 8th graders experiment with sodium silicate and ethyl alcohol to make a polymer. They also experiment with borax and glue to make a polymer....

Students use the scientific method to investigate the role of temperature in microbial growth. In this food preservation lesson, students set up an experiment with fruit in room temperature and in a refrigerator. They record the...

For this ionic and covalent compound worksheet, students investigate the properties of three unknown substances in order to determine if they are ionic or covalent compounds. They write conclusions about their results.

Grandma said to gargle with salt water for a sore throat. Was she right? In the last part of the seven-part unit, lab groups design an experiment to test a cells reaction to salt solutions. The pupils conduct their experiment to answer...

We can learn from the past to protect the future. Pairs look at two historical earthquakes: San Francisco, Calif., and Kobe, Japan. Pupils compare the two earthquakes and their impacts, then determine how engineers may use the...

Students study techniques for conducting a local environmental assessment in an ecologically sensitive area. Identification of native plants and methodologies for sampling is taught in the classroom and then reinforced in the field. The...

This lesson demonstrates differentiated instruction at its best. Over the course of 2-3 class periods, young chemists have the opportunity to gain a thorough understanding of metals and their chemical properties from a variety of...

There are many factors that affect how fast the glaciers are melting. A lab investigation has learners examine how the surrounding water affect the rate glaciers melt. They collect data from two samples of ice to determine how quickly...

Prepare scholars for micro and nanoscale investigations. A lab activity allows individuals to practice their experimental techniques while becoming to accustomed to the smaller scale of the materials. They also make decisions about the...

Micro what? Analyze microfluidics as an application in the medical community. A lab investigation highlights the importance of channel design in biotechnology. Learners modify channels and observe the behavior of the flow of the fluids.

In this detailed and comprehensive multi-day activity, budding evolutionary biologists use real data from lizard populations in the Canary Islands to examine evolution and natural selection. 

Take the time and energy learn about Earth's energy budget. An engaging unit of four lessons focuses on the components that make up Earth's energy budget. Future scientists come up with a formula for the energy budget, then use software...

There's more to light than ROYGBIV! An enlightening laboratory investigation has learners explore the world of infrared light. When they use goggles that take away visible light, they experience how things look with only infrared light.

Help! Someone's trying to take my DNA! An interesting lab experiment has scholars use basic materials to extract DNA. By applying ethanol, cold water, and a protease enzyme, like pineapple juice, they pull strands of DNA from peas,...

Cut milk cartons in half to make boats and let investigators attempt to sink them. They add dividing walls and observe what happens if marbles are put into only one of the newly formed compartments. Vocabulary is provided: buoyant force,...

Elementary life science explorers compare and contrast aquatic and terrestrial plants (elodea and soybeans) in a Venn diagram. Some background information is provided to support direct instruction, and general instructions are provided...

Students investigate the concept of lab safety using a variety of different activities. The equipment necessary is covered. They draw the different types of lab tools using a graphic organizer.

Students study chemistry.  In this laboratory lesson students watch the CSI episodes and investigate their laboratory techniques and discuss what they saw.

Students brainstorm ways to look for evidence and investigate suspects.  In this investigative lesson students pretend to be investigators and analyze a crime scene.
