Students explain how significant bridges are in our lives. In this technology activity, students research the history and characteristics of their assigned bridge and draw it on butcher block paper. They write a short tour...

Students create products from studying about matter that include: Make a "T" chart with matter and non matter items. Write a poem, song, or rap about matter. Five vocabulary words from the chapter must be included in the poem.

In this science worksheet, students select 24 of the dinosaur names from the list and write them in the spaces on the bingo card. They match each of the dinosaurs listed to their correct description.

Written to follow "Bacteria Lab I: Preparing Agar Plates and Culturing Bacteria," also found via the Lesson Planet site, this lab sheet instructs your microbiologists to test a bacteriocide for effectiveness. In the preceding lab, they...

After reading "Aquatic Alchemy," an article about recapturing water for reuse when in space, your class will use calcium hydroxide or hydrated lime to purify cloudy water. Geared toward high school chemistry or environmental science...

Students participate in a scavenger hunt using their sense of sight. They bring various texture materials from home and discuss how things feel. Students identify the smells inside five jars. They discuss things they hear and why hearing...

In this redox reaction worksheet, high schoolers perform a redox titration to determine the number of iodide ions that react with each mole of iodate (V) ions in a solution. They calculate their answer using a given equation.

Students examine the economic and ecological benefits of forest canopies. They read and discuss an article, answer questions, conduct research, draw field sketches of a canopy ecosystem, conduct a feasibility study, or prepare tourist...

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.
