We know solids have a density we can measure, but what about liquids? Lesson explores this concept and allows scholars to explore the relationship between volume and density. Graphing and analysis questions round out the activity. 

Are serving sizes for different foods always appropriate for what you need? In this hands-on activity, learners work in groups to estimate what one serving size of various foods are, and then evaluate their hypotheses by measuring...

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...

Though the publisher designated this unit for use with third through eighth grades, this particular lesson would be best used with middle schoolers due to the specific measurement skills required. Basically, they set up the reaction...

Children enjoy playing with silly putty, but it provides more than just fun. Young scientists make their own silly putty using different recipes. After a bit of fun, they test and graph the viscosity of each.

Learners explore the properties of matter.  In this cross curriculum three states of matter science lesson, students listen to the poem "Eighteen Flavors" by Shel Silverstein, and predict what will happen if listed ingredients are...

Seventh graders investigate the particulate level of solids, liquids, and gases. They examine how the particle method show the interplay between scientific theories and evidence.

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...

Fourth graders define the term matter. They compare properties of solids, liquids, and gases. They describe how matter changes from one state to another. They classify objects as either solid, liquid, or gas.

In this volume and surface area activity, 10th graders solve and complete 10 different word problems that include measuring various solids and cylinders. First, they determine the surface area of a cube and the edge of it. Then, students...

Students observe and explain how a change in temperature causes a physical change in a substance.  For this physical science lesson, students use a soap making kit to observe the effects of adding heat to the bar soap as they...

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 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 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...

Second graders listen to a book read to them entitled, WHAT MAKES A RAINBOW and recall and describe their five senses and what parts of their bodies use their five senses and then complete the Catch a Rainbow activity sheet using a...

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space...

Ever wonder why Pluto isn't considered a planet? Or how large the Earth is compared to the other inner planets? Explore the universe with a series of projects that simulate different aspects of our solar system. The activities require...

Entropy, it isn't what it used to be. Presentation includes kinetic-molecular theory, heat and internal energy, thermal equilibrium, temperature scales, laws of thermodynamics, entropy, latent heat of fusion, specific heat, calorimetry,...

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.

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...

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...

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...

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...
