Students recognize both a physical and chemical change in different substances. They determine which particles actually changed into different substances, and explain if it represented a physical or a chemical change.

Students titrate a sample of fatty acids with standardized sodium hydroxide solution. From the amount of base needed for neutralization and the mass of sample used for titration, the apparent average molar mass of the sample is...

Here is a good lesson which aptly describes how to do the classic "Oobleck" lab with your young scientists. Unfortunately, the "Oobleck Investigation Sheet" in the plan doesn't open. However, this is a very clear description about how to...

Learners make a starch-glucose solution and pour it through gel in order to separate the starch from the glucose. They examine how starch is a larger molecule than glucose and test for the presence of these substances using other...

Students answer questions about how microorganisms can affect our food supply and how they can be controlled. The first set of inquiry activities are directed by the teacher. Subsequent activities are based on students generating their...

Three experiments involving pennies help young chemists see the chemical reactions between copper and other elements. The first experiment is rhetorical (it prompts students to leave a bright penny out for a year) but the second two...

Young scholars become acquainted with the principles of liquid chromatography and construct a liquid chromatography column. Students also investigate the effects of different solvents and solvent concentrations in the separation process.

Young scholars use chromatography to separate substances in Kool-Aid, Crayola markers and leaves. In this chromatography lesson plan, students make chromatograms to separate substances in a mixture through absorption. Young scholars find...

Learners examine solubility and the significance of water.  In this aqueous solution lesson students complete a lab activity on soil profiles.

Students explore the components of matter. They discover what matter is, the states of matter, and how heat and cold cause it to change states in an online format. In addition, they complete internet-based lessons, activities, and quizzes.

Third graders identify the different states of matter. In this science lesson, 3rd graders describe the different components of solutions and mixtures. They create emulsions, foams and suspensions in the lab.

Students predict, observe and draw conclusions while working on an experiment with "slime." Students accurately record observations and draw conclusions about the experiment.

Young scholars participate in an experiment in which they culture bacteria in a lab setting. They record their observations and analyze the data. They answer comprehension questions to end the lesson.

Students participate in a lab experiment involving soap bubbles and making bubble prints. They blow bubbles into the soap and add paint to make bubble prints. With extra time, they can play with a variety of bubble toys to see what...

Students perform a laboratory exercise designed to show how DNA can easily be extracted from onion cells. They conduct an optional test for the presence of DNA using standard lab equipment.

Students collect data on causes of Acid Rain. In this science lesson plan, students simulate the effects that produce acid rain, collect and analyze data from their samples. They relate science and statistics in this lesson plan.  

Students work in small groups with a small set of 8 nuts and 5 bolts to assemble into combinations of 1 nut: 1 bolt, and 2 nuts: 1 bolt. They explore the outcome and discuss. Then a student mixes two clear, colorless solutions together...

Students are introduced to the principles of gel electrophoresis and also provides an opportunity for students to practice loading gels and prpetting. In this laboratory activity, food color is used to separate into constituent pigments.

Learners conduct experiments designed to detect the presence of CO2 by using a BTB that changes color (blue to yellow) in the presence of CO2. First, students experiment with the CO2 from combining vinegar and baking soda. In part two,...

Students isolate DNA from kiwi cells, spool DNA from a kiwi, describe role of the DNA and genes, and explain how knowledge of DNA and genes can be used in genetically modifying foods.

Young scholars examine how an estuary's plants and soil filter water before it flows into the ocean. They complete a lab report drawing and writing about what they observe after completing a water filter activity.

Students extract DNA from split peas. In this biology lesson plan, students hypothesize what DNA looks like and perform the experiment to verify their hypothesis. They explain the importance of DNA in living things.

Students perform a lab in which they extract DNA from onion cells. Students break through the cell and nuclear membranes and then break down the protein that the DNA is wrapped around.

Middle schoolers 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...
