In this biology worksheet, students look at the function of filtering in the nephron of the kidneys and the biochemistry is emphasized.

Students discuss the work "Filter." They list types of filters they know about and look at both clean and used filters. Students speculate on how a filter might be important to a fish. They listen to the instructor tell them about...

Elementary schoolers who are learning about filtration and mixtures could use this activity to gain practice in filtering techniques. In it, they are asked how to manipulate a container in a way that would lead to properly filtering...

Almost 200 slides make this a vast collection! It is a quirky collection, titled "Marine Fisheries Management," but having little to do with that occupation. What you will find are two-toned blue backgrounds with no pictures, but a few...

Immerse your chemistry class in the world of organic chemistry! Science scholars isolate acetaminophen from an over-the-counter sample during an intense and interesting lab. Groups use many different separation and analysis techniques to...

What is a reasonable percent yield in the manufacturing process? Scholars develop a process for producing chalk in the third lesson of a six-part series. Then, they must determine the theoretical and percent yield. Discussions about...

For this preparation of triiodomethane learning exercise, students use propanone to prepare triiodomethane. Students use filtration and recrystallization to produce the product. They determine the melting point using a melting point...

Young scholars examine soil. For this soil composition lesson students participate in soil sedimentation and filtration activities. The young scholars discuss what non-living and living things are in soil and why it is so important.

In this urinary system worksheet, students review the role the kidneys and nephrons play in the formation of urine. Students order the steps of the filtration of blood. This worksheet has 3 short answer and 10 fill in the blank questions.

Fifth graders describe a wetland habitat and its components. They provide, in writing, at least one example of a wetland food chain, relate wetlands to ecological functions, and relate the importance of wetland functions to their own...

Pupils examine how a sanitary landfill is constructed, how it functions, and how waste and leachate affects the areas around the landfill. After a discussion about landfills and leachates, students construct a Sanitary Landfill Model...

Chemistry explorers prepare a crystalline derivative and find its melting point. Once they discover the melting point, they can identify whether the substance is pure or an aldehyde or ketone. This outstanding laboratory activity helps...

Complete with teachers' notes for most of the slides, this is a tremendous presentation of the four types of tissues: epithelial, connective, nerve, and muscle. Each is displayed with pertinent vocabulary and photos of microscope slides...

Tenth graders use a classification key to identify organisms.  In this classification lesson plan students identify freshwater species of fish and document their observations. 

Explore homeostasis in animals with this all-encompassing worksheet. Advanced biology pupils consider a variety of mechanisms for maintaining internal conditions such as temperature and waste products. Eighteen short-answer questions...

Students explore mixtures and compounds. In this lesson, students do an experiment to distinguish between mixtures and compounds. Students complete ten different phases of the experiment testing many different substances. Students will...

Students use mushrooms to solve problems. In this environmental lesson, students study how fungi have been used to combat environmental problems. Students design strategies that employ mushrooms to combat other environmental challenges.

In this nephron worksheet, students color the parts of the nephron and answer five questions about the structures and functions of the parts of the nephron.

For this thermal decomposition of calcium carbonate learning exercise, students perform three experiments on calcium carbonate, make observations, and write the equations for each reaction. Students explain in detail what happened at...

Students discuss ammonia, and ways it may get into the aquarium. They complete a worksheet about the Nitrogen Cycle. Students learn how to get the ammonia and nitrite out of their aquarium.

Students examine how river travel affected the Lewis and Clark expedition. They define gravity, slope, and velocity, conduct a river formations experiment, complete an activity sheet, and watch a video about Lewis and Clark.

Students perform two experiments to show the properties of enzymes. They use pectinase to produce apple juice from applesauce to show enzyme action and then taste the difference between raw and boiled papaya seeds as evidence of enzyme...

Learners explore the effect of chemical erosion on statues and monuments. They use chalk to see what happens when limestone is placed in liquids with different pH values. They also discover several things that engineers are doing to...

Students perform simple experiments to show properties of enzymes through studying how apple sauce can turn into apple juice and experimenting with papaya seeds. Students witness how enzymes speed up reactions through witnessing the...
