In this salinity worksheet, students simulate conditions of salt and fresh water mixing and observe the various densities of these solutions based on their salinity.

In this mineral identification worksheet, students read nine vocabulary words and answer 5 short answer and fill-in-the-blank questions regarding minerals. There are four additional pages of related activities. 

Students compare fish anatomy. In this teacher demonstrated dissection instructional activity, students compare fish anatomy to that of humans. They explore different fish and their unique properties.  There are 4 distinct...

Fourth graders describe the various kinds of soils and how plants and animals are affected by them. They describe the baic needs of plants, scoring at least a 3 or 4 on a 4-point rubic. Students are able to predict and/or infer what...

For this atom worksheet, students read about the parts of the atom and how atoms combine into molecules and compounds. Students learn how to read a periodic table. This worksheet has 20 fill in the blank and 10 matching questions.

Students examine how hormones affect different tissues. In groups, they make their own hormone-receptor model and identify the characteristics of tissues that respond to the different hormones. To end the lesson, they examine the role...

In this atom worksheet, high schoolers read about the structure of the atom including its subatomic particles and John Dalton's theory of the atom. Students also read about the differences between atoms, molecules and compounds. They...

Young scholars examine the porosity of eggshells. In this eggshell properties lesson, students observe dyed eggs, then peel the eggs to see if the color was able to go through the shell and discuss why eggshells have pores.

Students identify and analyze a variety of sources for information and statistics on drugs. They map out why its important to know the facts about drugs. In addition, they show examples of what happens when you use drugs of any kind.

Young scholars develop an understanding of how aspirin works and how understanding it's interaction with other chemicals in the body aided doctors in medical research. They complete a lab that compares the reaction of regular aspirin...

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

Eighth graders are actively involved in the scientific method and inquiry as they form quick hypotheses based upon a teacher set of mystery liquids. They determine the need to make additional observations of the liquids.

Students study the process of evaporation.

Seventh graders hypothesize about the number of drops of liquid that can be placed on a penny before it spills over. They examine both the concept of devising a hypothesis and the idea of surface tension. They determine the difference...

Sixth graders distinguish between an observation and an inference distinguish between quantitative and qualitative observations of a scientific experiment. They record and organize data collected during an experiment.

Students, after making quantitative and qualitative observations of their rocks, construct a Venn diagram or dichotomous key to classify their rocks.

Fourth graders research soil layers and create a soil profile in a jar.  In this soil profile activity, 4th graders working in groups, research a given layer of soil, make a 3-5 minute presentation to the class, and complete a...

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...

Young scholars develop procedures to explore the behavior of fish.  In this scientific experiment lesson students from a hypothesis, write a question, identify different variables and controls in their experiment. 

Students studykinetic energy, friction, drag and acceleration by relating it to the Winter Olympics.  For this physical properties lesson students create tracks and determine how the course conditions affect bobsled, luge and...

Students observe liquids in different containers and then explore the concept that liquids have level surfaces. They identify those who are not at the center to reinforce the concept of liquid levels with a representational puzzle and...

Students use one of four absorbent products to separate as much of the oil and water mixture they are able to do. The purpose of this task is for students to collect and analyze data for the purpose of determining which absorbent is...

Ninth graders generate and analyze data to determine which and how much of two polymers best absorb oils, formulate procedure to accurately determine how many times its own weight particular polymer can absorb, and develop understanding...

Students participate in several density lab activities in order to clarify the misconceptions that solids sink and liquids float. Students work with triple beam balances to find mass of objects to calculate density.
