Students design experiments examining the effects of various solutes on water. They record results on graphs explaining any unexpected consequences of their experiments and determine if their hypotheses were correct.

Students investigate scientific measurement. They use a variety of scales to do the job and communicate the results correctly. The teacher uses socratic questioning throughout the lesson checking for comprehension. Students measure some...

Fourth graders explore whether the making of homemade ice cream is a physical change or a chemical change in a lab experiment. Students identify states of matter, describe the physical properties of states, and collect temperature data...

Fourth graders identify characteristics of a simple physical and chemical change. They describe objects by the properties of the materials from which they are made and that these properties can be used separate. Students describe the...

Third graders explore and identify the tools that can be used to measure length, mass/weight, and volume. They discuss how things are measured using different units, and observe the difference between the English and the Metric systems....

Students participate in a teacher demonstration of the water level in different beakers to investigate the measurement of volume. Next, working in small groups, they replicate the demonstration and determine how the measurements in the...

Middle schoolers explore what type of solutions freeze. They design their own experiments to compare how fresh water and salt water freezes. In addition, they write their observations in a journal and complete analysis questions.

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 measure the heat of physical and chemical changes in reactions.  For this chemistry lesson students determine at what extent changes emit or absorb heat. 

Students discover the properties of matter and how they change when composite materials are produced.  In this informative lesson students write up a question and procedure to an experiment then analyze and draw conclusions based on...

Students create an experiment. In this friction lesson plan, students review the concept of friction and complete a bottle roll activity. Students work in groups to create their own friction experiment.

Learners research the Gulf of Mexico oil spill and complete experiments to study the effects of oil spills. In this oil spill lesson, students read the NY Times feature on the gulf oil spill. Learners visit various links to research the...

Pupils discover density.  In this density lesson, students discover the properties of objects that allow them to float or sink in water.

Learners explore the physical properties of density. In this hands-on lesson, students calculate density and distinguish between intensive and extensive properties.

Fifth graders complete measurement problems where they use powers of ten, read metric measurement tools, estimate measurements, and more. In this measurement lesson plan, 5th graders complete 10 problems.

Young scholars explore math functions by completing math equation worksheets. In this inequality lesson, students define a list of math terms and discuss the difference between an equation and inequality. Young scholars utilize a real...

Students perform several tests on liquids. In this general science lesson, students compare the properties of polymeric and nonpolymeric liquids. They explain the composition and importance of macromolecules.

For this basics of science worksheet, students review the metric system, the difference between homogenous and heterogenous mixtures, the scientific method, and science lab first aid. This worksheet has 15 short answer, 43 fill in the...

Students explain the Chatelier's Principle. In this pH lesson, students identify factors that resist changes in pH of the ocean and why the ocean is becoming more acidic.

Eighth graders record the temperature change of the beakers. In this general science instructional activity, 8th graders create their own data table for recording observations. They discuss experimental results and cite real life...

Students examine soil samples for the presence of organic matter. They determine which soil sample from their area contains the highest amount of organic matter.

Students participate in a science lab to determine the pH of three different soil samples. Students conduct an experiment by creating a question, a hypothesis and then an investigation of soil samples. Then they compare colors apprearing...

Students investigate the potential toxicity of water samples using California blackworms to test water quality. They observe the worms' behaviors in different water samples and determine which sample has the highest toxicity. At the...

Students define density in their own words. In this physics lesson, students calculate density using mass and volume. They explain why some objects sink and some float.
