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...

Students investigate the properties of solids, liquids and gases. In this states of matter lesson plan, students observe dry ice and its characteristics. They calculate the density of dry ice and observe the sublimation of the dry ice...

Third graders examine the non-standard method of measurement and compare it to the metric system of measurement. In this introductory module lesson, 3rd graders discover the scientific observation. Students also develop communication...

Students examine the food pyramid. In this health/math lesson students make biscuits. Students are assigned a group to measure out ingredients. Students also discuss which part of the food pyramid biscuits fall into and the nutritional...

Some of kids' favorite toys are the products of science experiments. Scholars follow precise measurements to mix and create their own slime and Play-Doh. They observe the changing textures and the chemical reactions throughout the...

Students explore the states of water. In this science lesson, students use observation, measurement, and communication skills to describe water as it changes from a solid to a liquid.

Students assess whether there is liquid water on Mars by analyzing images and data.  In this planetary lesson students analyze temperature and pressure graphs and hypothesize about how water could have flowed on Mars.

Students explore the measurements of capacity by constructing a creative project in the shape of a man. The man has body parts that represent different units of measurement and can be used to make conversions. This is highly concrete and...

In this body fat measurement learning exercise, students will conduct an experiment to determine how the "under-water weighing" technique of measuring body fat works. Once the experiment is complete, students will complete 1 short answer...

In this experimental design and measurement worksheet, students answer questions about independent and dependent variables, they write hypotheses, they identify instruments that measure mass, weight, and volume and they calculate the...

Students investigate the rate of a chemical reaction. In this rate of reactions lesson plan, students use an electronic balance to measure the change in mass of a chemical reaction between hydrochloric acid and calcium carbonate. They...

In this volume worksheet, students take notes on the various ways to measure volume depending on if the substance is liquid, an irregular shaped solid, or a regular shaped solid.

In this density worksheet, learners answer 16 questions related to density. They read diagrams of graduated cylinders and determine the liquid's mass, volume and density. They find the density of objects and answer 3 questions about...

Most scholars associate density with floating, but how do scientists determine the exact density of an unknown liquid? The third lesson in a seven-part series challenges scholars to find the mass and volume of two unknown liquids. Each...

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...

Twenty-four questions about matter, the states of matter and the properties of matter make up this interactive online worksheet. Your class will determine the volume of water, the shape of water and the shapes of matter.

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...

Pupils work on seven problems that use equations and expressions to solve geometry problems. The questions range from finding equivalent expressions to finding areas and volumes of figures. Learners apply their knowledge of angle...

Learners solve 14 word problems and 25 weight conversions.

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

Students develop their own techniques for drawing a small sample of solutions into a straw. They hypothesize ways to increase the density of water, and discuss how salt-free rainwater tends to float on top of salty seawater.

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 experiment to find which liquids are more dense.  In this density and mass lesson, students predict and then test objects to observe and measure their density. students observe which items sink and float. Students complete...
