Graph growth in the US. Given population and area data for the United States for a period of 200 years, class members create graphs to interpret the growth over time. Graphs include population, area, population density, and population...

Isn't technology great? The 12th installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program introduces technology that marine scientists use. Pupils take part in an activity using conductivity,...

Fertilizer can mean the difference between a profit and a loss. Scholars use an online interactive to explore the effects of fertilizing in agriculture. Given information about the nitrogen levels in the soil, they decide the fertilizer...

Earth's atmosphere is full of different energies, from thermal to wind to electromagnetic radiation. Through the presentation, class members discover these energies and how they determine weather patterns.

Students practice determining liquid densities in a short, hands-on lab activity. Students use a graduated cylinder to measure out 100 milliliters of a liquid, find its mass using a balance, and record measurements in a data table....

In this density laboratory worksheet, students complete 2 prior knowledge questions, then use the "Density Laboratory Gizmo" to complete several activities, answering short answer questions when finished.

Students must plan, design, and conduct an experiment that answers the scientific question: "Come up with a question that addresses the factors (variables) of the water and its effect on whether an object floats or sinks."

Learners research the impact that human activity had on Pennsylvania's water supply over time. In this water quality lesson plan, students research, discuss, and write about how Pennsylvania's water quality has been affected and what...

In this properties of matter worksheet, students complete 18 fill in the blank questions about mass, density, volume or weight.

In this properties of matter worksheet, learners answer 18 questions about mass, density, volume or weight. All of the questions are multiple choice.

Students measure the properties of two different types of soap and wood and calculate their densities. Then they predict whether or not whether or not each object would float or sink in fresh or salt water.

Students observe and experiment with the concept of density. This is done using a simple experiment that helps them to apply scientific principles of observation and proving a hypothesis.

Combine science and literature with this instructional activity on buoyancy. Read There's an Ant in Anthony by Bernard Most to examine words containing the letters a, n, and t. Then introduce your class to the word "buoyant."...

Oceanography experts use candy to construct a model of a bio-physical mooring that would test a variety of factors. Each piece of equipment to be included on the mooring is described within the write-up. As pupils gather the candies for...

Blow your class away with a gust of humor as they watch this video about air pressure and wind. Along the way, they find that the density of air (as determined by temperature, altitude, and water vapor content) leads to air pressure...

Learn why what goes up must come down in both air and liquids. Investigators discover how convection transfers thermal energy and the movement of particles in liquids and gases due to density differences by viewing an animated video....

In this solutions worksheet, students identify solutes and solvents from a list of solutions and they draw water molecules bonding to each other. They fill in the blanks with terms related to bonding in solutions, density of solutions...

A well-developed lab sheet guides physical science learners through an investigation of kinetic and potential energy. In small groups, collaborators discover whether or not the ramp height or mass of an object has an effect on the...

Plankton are so abundant in the ocean they outweigh all of the animals in the sea. In this three day activity, groups discuss and become familiar with plankton, capture females, and look for egg production on day three. 

An informative lesson focuses on heavy metal contamination of environments. Classes read about, discuss, and answer questions pertaining to sources of heavy metals in the environment. To finish the 35th installment of 36, individuals...

How do robots assist ocean explorers in collecting data and images? The final installment in a five-part series has science scholars examine underwater images collected by robots and identify the organisms shown. Groups then calculate...

The color, density, and smell of urine all relate to kidney function. Pupils observe the kidney controlling the concentration of water through three different steps. It mentions how each function might change the appearance and scent of...

A neat handout immerses learners in the history of canoe making. After reading, small groups of mini engineers work to craft a canoe that will not be immersed! This is an ideal exercise in engineering design for your STEM curriculum or...

Why are greenhouse gases called greenhouse gases? Young Earth scientists learn about greenhouse gases though experimentation in the second installment of a 3-part series. They use lamps to model radiant energy as well...
