Students participate in a demonstration that illustrates the relative amounts of salt in various bodies of water including the Dead Sea, Sallt Lake, Ocean water and distilled water. They taste and compare various mixtures.

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.

Pupils 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 explore composting. In this composting instructional activity, students use compound microscopes to observe the microbial communities in compost. Observations and documentation of changes will occur over the course of several...

Students examine how one of the ways the mining companies extract coal is through the flotation method where air bubbles float coal particles to the top of a solution. The coal is scooped off and separated. They participate in the...

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

Students conduct an experiment to observe the properties of both salt and freshwater. They explain why freshwater will stay at the surface while salt water will travel up a river bottom because of density. Students also research the...

Students make a crystal snowflake decoration out of string, pipe cleaners, food coloring, boiling water, and more. In this snowflake lesson plan, students let it dry over night and see crystals in the morning.

Students make their own pH indicator from red cabbage. Red cabbage contains a chemical that turns from its natural deep purple color to red in acids and blue in bases. Students boil the cabbage to get the pH indicator.

Students discover how paint is made, then create their own paint which they will use to create a picture. After witnessing the processes of emulsion and suspension, students work in groups to create their own paint, and then create...

Students investigate the mixtures of solutions. They utilize cups filled with bases and acids. Students test and determine the pH of each cup. The multiple cups are compared to each other in order to chart acids and bases according to pH...

Pupils use wire to make knots and submerse them in pans of detergent to observe how the soap film clings to the wire. They discover this film is called the Seifert Surface. After drawing pictures of the surface, they discuss what...

Learners investigate and explain the differences active transport versus passive transport. This lesson includes an individual and group activity. The basic steps of electrophores is the focus of inquiry. Identification of the pure...

Second graders use knowledge of measurements and ratios to mix various combinations of liquid starch and glue. They chart their ratios, make observations, and write a summary of the activity. They mix their own batch of Crazy Putty to...

Students examine hardwoods and their pores. They discover that some pores allow for air movement while others do not. They also examine and identify the different types of hardwoods.

Pupils explore electrophoresis, a technique used to isolate DNA. They assemble a gel chamber for separating mixtures. Students observe separation influenced by electric charge. They define separation through gel electrophoresis.

Students explore DNA and restriction enzymes using fragments of DNA separated by electrophoresis on an agarose gel. They analyze the results to see "whodunit".

Students explore designing and building a plant box. Based upon desired parameters, students create a set of plant box blueprints. Next, they choose the material and build the box. Agricultural teams select the soil mixture, fertilizer...

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.

Students 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 separate a mixture of pigments with ion exchange chromatography and predict whether the ion-exchange matrix is positively or negatively charged based on the type of pigment bonded to the matrix.

Sixth graders experiment with the froth flotation process to extract metallic ore by using basic chemicals and equipment in the science classroom.

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