Population Biology - Biology Teaching Thesis
Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...

Wildlife Study Comparison
Environmental science classes read articles about two different scientific studies. One is about the effects of contraceptive chemicals on fertility, and the other is about how a pesticide may be reducing bone density in exposed...

Cents-ible Chemistry-Analysis of the Metal in a Penny
Students determine the base metals and surface metals in a penny. In this analysis of metals lesson plan, students determine the density of five pennies minted in different years. They use different chemicals such as hydrochloric acid,...

Grand Designs And Great Failures
Students extend their understanding of floating, sinking, density, and buoyancy and apply it to the design and testing of ships. students discover that most ships are constructed very similarly-whether they are schooners or destroyers.

Addition Polymerization: Preparation of Polystyrene Using Two Types of Initiators
Advanced chemistry classes compare the polymerization of styrene using two different initators: benzoyl peroxide and aluminum chloride. Once they synthesize polystyrene, they compare the two producet for melting point and density. There...

Condensation Polymerization: Preparation of Nylon 6/6
Students participate in a lab activity in which they synthesize nylon 6/6, calculate the percent yield by mass, identify the polymer as thermoplastic or thermoset, and determine the melting point, density and end-product use of the polymer.

Do You See What Icy?
Here is a lesson plan that kicks off with a question. "How does ice floating on the ocean act as it melts?" As learners investigate this natural phenomenon, they'll discover that it has a lot to do with temperature, salinity, and the...

Sink or Float?
Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

The Heat of Fusion of Ice
Learners measure the heat of fusion of ice. In this heat of fusion lesson plan, students use a calorimeter or Styrofoam cup and thermometer to measure the change in temperature of the water in their calorimeter. This allows learners to...

Fish and Zooplankton Through Remote Sensing
Ecology aces examine sea surface temperature maps and relate temperatures to concentration in fish and zooplankton populations. Take your class to a computer lab and provide experience with actual remote sensing data. Some of the links...

What Is a "Convection Cell"?
Round and round in circles it goes! A hands-on activity has learners recreate a model of a convection cell. They watch as the difference in density of their materials creates a current.

Sea Water Freeze
Middle schoolers observe how salinity affects the time it takes water to freeze. They participate in an experiment to determine that ice is essentially salt-free whether formed from fresh or salt water

How Far Away Is Space?
Outer space may be a lot closer than you think! Science scholars model the layers of the atmosphere using transparencies to gain insight into the scale of space. The resource includes ideas to tailor the activity to the skill level of...

What Is Special About Polyethylene Food Storage Bags?
Students participate in an investigation in which they compare a polyethylene bag designed for recycling or disposal with a polyethylene food storage bag. Students use hexane to determine the differences between the low density...

Buoyancy Boats
What did the sea say to the boat? Nothing, it just waved. An inquiry-based instructional activity starts with a simple concept on the Archimedes Principle and challenges pupils to make something out of clay that floats....

A Whole New World: The Search for Water
Scholars find Earth won't support humans much longer and need to identify a planet with water to inhabit. They test four unknown samples and determine which is the closest to water. Then they explain and defend their results.

Invasives and Macroinvertebrates
Students view macroinvertebrates, or discuss previous collection activity. They graph data on macroinvertebrates in the Hudson River. Students discuss the relationship between habitat, environmental changes, and invertebrate diversity or...

Saltwater Science
Students conduct an experiment that shows them how salt water allows things to float. In this salt water lesson plan, students mix ingredients together to create salt water and observe how it makes the oceans dense. They then interpret...

Sound
Since light travels faster than sound, some people may appear bright until you hear them speak. The presentation covers what sound is, how fast it travels in various mediums, properties of sound, hearing, and the parts of the human...

Density Lab
In this biology worksheet, students use the website given to become familiar with the equipment of a lab. The activity involves a link to a virtual laboratory. Then they determine an objects mass and volume by placing it in a graduate...

Density and Buoyancy Experimental Design
Pupils 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."

Earth Science: The Structure of the Earth
Young scholars identify and complete activities about the structure of the Earth. In this Earth structure lesson, students view a Powerpoint about the Earth's layers and complete a diagram. young scholars compare temperatures in the...

It's OK to Reach Your Boiling Point!
Students view a video which introduces them to density and the states of matter. They experiment, collect data, and graph the boiling/freezing points of several edible items...and then make brownies!
