Students test different water solutions for the presence of ions. For this water testing lesson plan, students test for iron, calcium, chloride and sulfate ions in solutions. They indicate positive tests based on their results and they...

In this labeling a cross-section of a Bacterium cell worksheet, students use the glossary of Bacterium cell terms to help identify and label each cell part. Students label nine parts of the Bacterium cell.

In this electrolytic cell worksheet, learners read about car batteries and how they produce electricity for cars to run. They answer six questions about electrolytic cells and oxidation-reduction reactions.

In this online interactive reading comprehension worksheet, learners respond to 11 short answer and essay questions based on Winesburg, Ohio. Students may also access an online quiz on the selection using the link at the bottom of the page.

In this mineral worksheet, students use an on line source to answer questions about minerals, about resources and their uses, about fireworks and about birthstones.

Students explore the properties of enzymes. In this chemical reaction lesson, students explore enzymes through a Web-quest and investigative study. Students will collect and summarize data and create a class presentation. This lesson is...

Students examine chemical leavening agents in dough and batters.

Young scholars discover the law of conservation of mass though experimentation.  In this chemistry lesson, students experiment with acid - base indicators to determine the presence of carbon dioxide. Young scholars complete the labs...

Learners use a Colorimetric test to measure pH and gain the importance to life in an aquatic ecosystem pH is. They explore the dramatic effect pH level can have on a water body. Students test the pH level of many water samples.

In this chemistry worksheet, students describe an atom, its parts, the charges of these parts, and atoms life functions. Then they explain what the octet rule states for the placements of electrons around the nucleus of an atom. Students...

Students do hands-on activities and read information online in order to answer the central question of this lesson: How does understanding the chemistry of hair care, including the role of pH, help in the development of better hair-care...

In this dietary fibers worksheet, students compare and contrast the properties of different fibers: cellulose, hemicellulose, pectin, guar, agar, and xanthan gum. This worksheet has 5 short answer questions.

Show your chemistry class a graphic organizer classifying the types of chemical reactions. A few additional slides are included on the formation of magnesium chloride, the production of methanol, and a diagram of a mixture of molecules....

Pupils prepare successful wet mount slide of Elodea. They determine and identify environmental conditions that induce cytoplasmic streaming. They determine the positive aspects of cytoplasmic streaming. They illustrate knowledge and use...

Students investigate the concept of a polymer using an experimental design of protecting an egg in a bookbag. They test the properties of polymers and form an educated solution to the proposed problem. Then they describe the steps used...

Students isolate DNA from different food sources. In this biology activity, students research DNA extraction. They analyze DNA stands collected from the lab, and compare the differences between each.

Students explain the function of DNA in the body. In this biology lesson, students build a DNA model using simple materials. They demonstrate how bases pair up in the helix.

High schoolers study genes, DNA and medical research. They watch "The Code of Life" video and answer discussion questions regarding the transcription and translation of DNA and how errors in these processes and mutations in DNA can...

Students examine the entire DNA base sequence of the human adenosine deaminase gene after it is printed out from the source disk provided. The enormous length of a single gene as well as the immense difference in length between intron...

Students construct a 3-D model of DNA. They demonstrate an awareness of base pairs in written work and in a model. Students model DNA replication using edible materials. They record concluding thoughts in their science notebooks.

Ninth graders investigate what restriction enzymes do, and explain how a DNA sample can link a suspect to a crime.

Young scholars are able to explain their models to other students and to their parents. Then young scholars like to decorate the room by hanging the models or constructing mobiles of a number of models.
