Students complete a lab to help develop a comprehension of stiochiometry. They review equation writing, equation balancing, and stiochiometry. Studnets are given the following information: Sloppy students from the previous class have...

Students recognize that body design affects balance. They investigate the basic structure of a dinosaur body to see how it achieved balance, then build any dinosaur body system they want, using small marshmallows and extra straws as needed.

Students investigate the study of pedigree designs and human genetics. They construct the pedigree representing two, three, or four generations. They investigate their family members' traits for ear lobe attachment, tongue rolling,...

In this crime scene investigation worksheet, students simulate DNA sequencing and DNA restriction analysis using paper strips of DNA. Students compare the crime scene DNA to the suspects and determine who is guilty.

Students investigate projectile motion. In this projectile motion lesson, students investigate a website with an interactive lesson. Students view the changes in the projectile they see in the lesson. Students watch short video clips and...

Learners read about how forensic entomologists use maggots to solve murders. In this forensic science lesson, students read an article and answer questions. They go to different websites about evidence and fingerprinting. 

Students examine the different techniques that may be used to reduce carbon dioxide in the atmosphere.  In this ocean pollution lesson students divide into groups and complete a lab to see how the ocean holds carbon dioxide.

Students conduct a series of investigations on the unique properties of water. In this general science activity, students explain what causes water's surface tension. They explain the different stages in the water cycle.

Students define, identify and illustrate the parts of an atom, and investigate the Bohr atomic model. Students watch a multimedia presentation to understand an atom's parts and their functions. In groups, they create a model of an atom...

Students investigate the interference of various drugs on an embryo through experimentation. This is an open-ended lab to allow students to see effects of various chemicals humans choose to put in their bodies and create questions they...

High schoolers investigate the concept of diffusion through a membrane. They do this through the conduction of a simple experiment. Students make observations while determining if the smell of different chemicals seeps through the...

Students address common misconceptions concerning reflection, light and mirrors. They investigate light reflection in mirrors and determine how light is transferred to the eye. In addition, they make predictions and then test them...

Students investigate safe laboratory procedures, classroom management guidelines, and group roles and procedures. They study a set of safety guidelines with their parents, and to sign a contract stating that they understand the...

In this science worksheet, students use the diatoms present in water in order to test water quality and perform data collection and interpretation.

High schoolers participate in a forensic science activity.  In this crime solving instructional activity, students investigate fingerprints, and other crime scene evidence to solve an imaginary crime. 

Students investigate climate change and how the properties of carbon dioxide and methane play a part.  In this climate lesson students use a chemical reaction to trap CO2 and methane.

Students, after researching and brainstorming about aquifers and locating aquifer maps of Texas, participate in the building of a model of an aquifer complete with a pumping station. They also answer a variety of questions at the...

Students explore the concept of environmental stewardship. In this science activity, students discover how scientists assess damages to the environment following oil spills. Students conduct a simulation of a public meeting in order to...

Sixth graders investigate the role of owls in their ecosystem. In this food chain lesson, 6th graders illustrate an owl food chain, dissect an owl pellet, and analyze data. Students discuss what would happen to owls if there were an...

Students discuss a number of career possibilities in science. They also examine a scientist's work.

Fifth graders observe the video, Exploring Light and Color. They access a website to create their own light show. They conduct lab experiments to investigate refraction, reflection,and other light-related topics.

Sixth graders read about and study motion. They conduct a lab in which they calculate speed using track records at their school. They graph the results and then invite a guest speaker (an officer from the local police department) who...

Students investigate the worm and the cockroach. In this organisms lesson, students visit suggested websites to identify the characteristics of worms and cockroaches.  Students dissect a worm and observe a live cockroach. Students...

Young scholars study reaction rates, what determines how fast a reaction happens and how the chemical changes occur.  For this reactions lesson students complete a lab where they use Alka-Seltzer to observe reaction rate and create...
