Eighth graders determine the amount of agitation necessary to dissolve various sized sugar particles. This task assess students' abilities to collect, organize, and interpret data, create appropriate graphs, predict future events based...

In this mixtures pre-lab activity, students compare and contrast suspensions and colloids and solutions and colloids. Students describe the Tyndall effect. This activity has 10 short answer questions.

Students explore chemical cahnges and the effect of temperature on chemical mixturees, They make observations of the behavior and appearance of certain chemical mixtures and reactions.

In this soap instructional activity, students produce soap in the laboratory and test their product by using it to wash away engine oil. Students answer four questions about tests they perform on their soap.

Young scholars experiment with solids and liquids. For this mixtures of matter lesson, students combine matter to form solutions. Young scholars hypothesize, test, and analyze the data to draw conclusions. The lesson can be extended by...

Students construct a water filter. In this engineering lesson, students discover how to construct a water filtration system. Students work in groups to sort tools by their properties. Students analyze and construct a water filtration...

Students explore the three types of mixtures through the use of interactive video. They experiment making mixtures using a variety of ingredients, while observing, comparing and contrasting, and identifying the types of mixtures.

Students find a way to mix oil and water. In this emulsion lesson, students attempt to mix oil and water, then add egg yolk to the mixture to serve as an emulsifier and observe the results.

Students experiment with acids and bases using technology-based "probe-ware", computers, and household products in this exciting biology/chemistry lesson. The lesson was written for an advanced 6th grade class.

Students investigate why cells divide. For this cell size lesson plan, students observe how far a solution travels into 3 different size model cells of agar. They answer questions about the most effect movement of "nutrients" into the...

Students mix solutions of polyvinyl alcohol and borax. They predict what happen and record their observations. They prepare a T-chart comparing Jell-o to their mixture.

Fourth graders use mucilage glue and magnesium sulfate to make crystals. They mix the ingredients, place a drop on a glass slide and observe the forming crystals.

Student statisticians calculate ratios to determine how many shades of green were mixed by Ms. Baca's art class. They graph the number of blue parts against the number of yellow parts for each combination and discover that some produce...

Investigate the Law of Conservation of Mass through a lab exploration. Individuals combine materials to initiate chemical reactions. They monitor for signs of reactions and measure the masses before and after the reactions for...
