High schoolers separate food coloring using liquid chromatography. In this chemistry lesson plan, students explain the effects of different solvents on the rate of separation.

In this chemistry quiz worksheet, students complete a set of 10 multiple choice questions covering a variety of chemistry concepts.

Pupils make a polymer but they won't be getting instructions. They'll get materials and they must figure it out on their own and report the actual steps needed back to the teacher.

Students solve systems of equations. For this algebra lesson, students use elimination and substitution to solve for the point of intersection. They use graphing to see where the two lines intersect.

Young scholars 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.

Young scholars explore how chemicals change water. In this chemical change instructional activity, students participate in an experiment to observe how salt effects ice and how ice cream freezes.

Students learn how science affects foods. In this chemical reactions lesson, students make two kinds of ice cream. They evaluate the different changes based on the ingredients.

Students explain monomer/polymer chemistry of starches and sugars.

Students assume the role of an engineer or planner. As an engineer or planner they must come up with ideas that can be put into place to control floods. They produce a working model of flood control.

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

Pupils describe the Le Chatelier Principle. They participate in an experiment in which they observe the changes in an equilibrium system. They answer discussion questions to end the lesson.

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.

In this fermentation worksheet, students conduct an experiment to illustrate how the yeast fermentation process is used to produce carbonation. This worksheet has 5 short answer questions.

Students create coal flowers. In this mining lesson plan, students discuss the importance of coal during the 1800s and use ingredients to make coal flowers. Students determine the effect temperature has on crystal formation.

Students make their own recipe. In this art lesson, students mix dry ingredients with a little water and see the changes made.

Students make ice cream as a result of viewing changes of states of matter. In this matter lesson plan, students learn how heating and cooling can effect a state of matter to change.

This is an advanced rates of reactions worksheet. Students will be determining reaction times, molarities, and reactions rates for different reactions.

Students explore biology by participating in a fun science experiment. In this DNA instructional activity, students discuss what DNA is and where it comes from. Students utilize two bananas, a blender and a microscope to view the DNA of...

Students perform tests on different chemicals to determine their chemical properties. In this forensic science instructional activity, students identify an unknown sample using its physical and chemical properties. They solve a fictional...

Students 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.

Learners 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.

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

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 use thin layer chromatography, TLC, to separate various pigments found in plants.
