Young chemists create gold nanoparticles as they learn to measure accurately with the metric system. They create an advertisement for the application of nanotechnology to complete the first lesson in a series of six.

Groups use a marble to determine the viscosity of household fluids. The procedure calls for pupils to measure the amount of time it takes a marble to fall a specified distance in the fluids. Using unit conversions and algebra, the teams...

First graders investigate how water can be both a liquid and a solid. They weigh popsicles and observe them as they write in their science journals. They measure the liquid as the popsicle melts and refreeze them to change them back...

In this science worksheet, students concentrate on attaining new knowledge of the science standard using the creative medium of games and puzzles.

Fascinating reading about nanotechnology, nanoscale properties, and liquid crystals precedes a fun activity for young engineers. They measure their hands in nanometers, research, and then investigate how heat effects a sheet containing...

Middle schoolers explore geometry by completing a physics activity on-line. In this mass measurement lesson, pupils define the terms mass, volume, and density and identify their relationship with each other. They complete an on-line...

Third graders practice measuring different objects. They discover the concepts of ratio and proportion and practice converting numbers into the correct unit. They read stories as well to help them with the concepts.

Fahrenheit? Celsius? What's the difference, and where did these two temperature scales originate? Your pupils will learn all about these topics by reading the passage included here. After reading, individuals respond to five questions...

Fourth graders participate in a teacher-led discussion about temperature--hot and cold. Each group of students is assigned specific materials for their lab experiment. They record temperatures measured in their journals and then plot...

Third graders investigate the three states of matter and the properties of materials as they undergo physical changes. They identify examples of each type of matter, role-play atoms in solids, liquids, and gases, and conduct an...

In this science worksheet, middle schoolers identify the amount of liquid that is present in a container and make a conversion for the five problems.

Open this lesson by demonstrating the production of acidic carbon dioxide gas by activated yeast. Emerging ecologists then experiment with seashells to discover the effect of ocean acidification on shelled marine organisms. They measure...

Groups suspend objects within layers of liquids to determine the densities of different liquids and compare them to the densities of objects calculated in Part 1. The groups then carefully test their calculations by layering the...

Using the natural pH indicator of red cabbage juice, groups determine the pH of different everyday liquids. As they work, pupils gain an understanding of pH that may help deal with contaminants in the water supply. 

A comprehensive practice exam, this resource covers many areas of chemistry. The test includes 71 multiple choice questions on topics such as problem solving, chemical equations, chemical formulas, thermodynamics, acids and bases, and...

Create a model to study a microscopic phenomenon. The seventh of 12 lessons uses an egg (without its shell) to represent a cell membrane. Using different solutions, learners explore the concept of cell diffusion. They monitor...

This cool lesson plan is ideal for elementary engineers or physical scientists, especially when learning about heat transfer and insulation. After reading a page of background information, engineering teams collaborate to design and...

In this chemistry worksheet, students examine a concept in science and then use the knowledge in application by conducting an experiment.

How do cohesion and adhesion work together? The third installment of a nine-part series teaches young scientists the difference between adhesion and cohesion. They also learn how cohesion and adhesion work together to cause capillary...

Students examine why having standardized units of measurement is important. They investigate the use of non-standard measure, twigs, while measuring the piece of tape. Next, they experiment with straws, paper clips, and rulers before...

First graders explore Oobleck. They manipulate and observe the properties of Oobleck. Students discuss the differences between solids and liquids. They investigate Oobleck. Students write a sentence describing what they observed about...

Third graders define matter as anything that takes up space and has mass, recognize, through experimentation and observation, that matter exists in three forms, including solid, liquid, and gas, and discuss characteristics of each form...

In this review of general science activity, students classify examples of matter as mixtures or substances, homogeneous or heterogeneous mixtures, or elements or compounds. Students also convert several examples using the standard units...

Students study the water cycle and the different forms of water.  In this exploratory lesson plan students observe, measure and describe water as it changes state.
