Students experiment and hypothesize about surface tension and cohesion, using water, ground black pepper, liquid soap, and other household products.

This course focuses on general methods and strategies for the synthesis of complex organic molecules. Emphasis is on strategies for stereoselective synthesis, including stereocontrolled synthesis of complex acyclic compounds.

Thinking about numbers using frames of 10 can be a helpful way to learn basic number facts. The four games that can be played with this applet help to develop counting and addition skills. (This applet works well when used in conjunction with the Five Frame applet.)

This investigation is a laboratory activity in which the alkalinity of 2 types of substrates (carbonate vs. non-carbonate) are compared on the basis of titration. Students will reflect on the relationship of alkalinity and toxic heavy metals. Teaching ideas from: Project Wet, Water Education for Teachers as found in: "Healthy Water Healthy People, Field Monitoring Guide "(2003)

Students construct "a tetrahedron and describe the linear, area and volume using non-traditional units of measure. Four tetrahedra are combined to form a similar tetrahedron whose linear dimensions are twice the original tetrahedron. The area and volume relationships between the first and second tetrahedra are explored, and generalizations for the relationships are developed." (from NCTM Illuminations)

In this activity, students calculate the cost of the energy used to operate a common three-bulb light fixture, and compare the costs and amount of CO2 produced for similar incandescent and compact fluorescent light bulbs.

Prior to reaching households, water is exposed to a variety of treatments designed to render it fit for human consumption and use. One of the first treatment steps is the removal of suspended solids using chemical additives called flocculants. In this activity, students learn about two commonly used flocculants and clean water collected from a local pond or river. They experiment with flocculant, stirring and pH variables.

This is a classroom lab investigation where students use the story of the three bears to discover inadequacies in the story and discover how to make them correct. Convection, conduction and radiation are involved.

This is a classroom activity in which students explore solids, liquids, and gases, and their properties. This provides hands on experience for all students.

This activity is a summary/assessment assignment which allows for differentiation and student choice. Students are assessed in their knowledge of the atomic model and the arrangement of elements on the periodic table.

This project is a classroom investigation where students design a chemical torpedo out of pipettes, baking soda and vinegar to travel down a rain gutter. While working on the project the students will have to analyze their design, interpret their success and failures, adapt their creation and compete against other students in distance and velocities of their launched torpedo.

This lab introduces or reinforces the concept of specific heat and the transfer of heat amongst substances.

This activity is an investigation into the relationship between alkane length and boiling points. Students develop a mathematical model of this relationship and use it to make predictions and error analysis.

Students will classify elements as metals, non-metals and metalloids based on their observtions of appearance, conductivity, malleability and reactivity with dilute acid. They will observe the location of these groups on the periodic table.

In this video segment adapted from ZOOM, the cast tries to design and build a bridge made out of drinking straws that will support the weight of 200 pennies.

This interactive activity, from the Building Big Web site, explores tunneling and the tools and methods used to do the job.

In this activity, students will learn the concept of half-life of a radioactive material. Students will create and be able to recognize a graph representing the half-life of an imaginary radioactive element.

The brief video clips on this webpage illustrate the range of number sense exhibited by students in grades Pre K-2. In interviews, Cena and Jonathan, both age 7, and Rudy, age 9, demonstrate different levels of understanding number and place value concepts. The page includes discussion questions for each set of videos as well as concluding reflection questions.

In this activity students will create their own toothpaste exploring and experiementing with natural ingredients.
