Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.

With paper DNA patterns, budding biologists model translation and base-pair substitution within sequences. Through these activities, they examine how mutations can result in genetic disorders. The modeling that occurs is an enlightening...

Biologists extract the DNA from a strawberry. After completing the procedure, learners write answers to a few questions on the lab sheet provided. This is ideal lab practice during a DNA unit in your general biology course. 

Students identify the abiotic factors that influence a river or stream and the organisms that live in it. They measure several abiotic and biotic parameters to gauge water quality. Students examine the biotic environment by identifying...

In this science worksheet, students read about enzymes and nutrition. Students also answer 2 comprehension questions about the reading.

Fifth graders examine polymers and how they are formed.  In this chemistry lesson students complete their own polymer experiment then discuss what they learned. 

Scratch and sniff an introduction to organic chemical reactions. A creative lesson has individuals study the esters commonly used in scratch-and-sniff stickers and advertisements. Following the lab procedure, scholars create the organic...

In this chemistry worksheet, students examine the oxidation state in order to apply it in the laboratory setting. The sheet includes in depth background information.

Every muscle movement requires energy, but where does that energy come from? Scholars answer this question and more as they complete a worksheet. By following the directions, completing research, and discussing it as a class, they begin...

Learners examines the arctic food web with a short video about polar bears and an article about bears and warming temperatures. They design an arctic food web and discuss the trophic cascade that could come from climate...

In this metabolism test review, students define several terms. Students write balanced chemical equations for aerobic cellular respiration. Students complete several multiple choice questions.

Students study why corn is a biodegradable, renewable resource.  In this ethanol lesson students build models and observe a chemical reaction.

High schoolers write a balanced chemical reaction. They articulate how burning fossil fuels increase the carbon dioxide levels in the atmosphere. Students incorporate all the environmental risks involved as well.

In this DNA worksheet, high schoolers read information about DNA and messenger RNA. Then students complete 16 short answer questions and color 2 images.

In this chromosome worksheet students complete a crossword puzzle by answering questions on DNA, nucleic acids, nucleotides and RNA.  

Tenth graders develop a hypothesis and explain what they observed on an activity.  In this investigative lesson students observe osmosis and report their data using a graph. 

In this DNA worksheet, students access a website to determine the information that was used to understand DNA replication. Students compare the difference between observations and opinions. This worksheet has 7 short answer questions and...

Students investigate bio-fuel. In this investigative lesson, students create bio-fuel from vegetable oil waste. Students will analyze, predict, collect and synthesize data from their experiments with bio-fuel.

Students experiment with crystals and polymers and examine their roles in food science.

Students investigate how to denature proteins. In this denaturing protein lesson plan, students explore the different ways to denature proteins in the lab. They use heat, acids and bases, organic compounds and heavy metals to denature...

Students identify the periodic table trends and predict material properties. They also design and conduct simple experiments and test material properties. Finally, students compare and contrast material properties and that chemical...

In this atom worksheet, students review the subatomic particles, the scientists associated with the atomic theory, and the periodic table. This worksheet has 15 matching, 24 fill in the blank, and 11 short answer questions.

Students calculate the Balmer series. For this physics lesson, students observe hydrogen lamp spectra using spectrometers. They calculate wavelength and compare them with their theoretical calculations.

Students, in groups, take samples from a creek and keep a field journal on their samples. They also perform tests on their samples.
