Here is a lesson which describes a lab activity in which a rat is dissected, and its heart is studied. The lesson has ample background information about three of the rats internal systems, and excellent lab sheets that support the...

Here is an interesting science activity/activity which has learners working in groups in order to simulate experiments done at the Jefferson Science Lab. In this one, groups use a pie tin, a Hula Hoops, a marble, and a magic marker to...

Here is a good lesson which aptly describes how to do the classic "Oobleck" lab with your young scientists. Unfortunately, the "Oobleck Investigation Sheet" in the plan doesn't open. However, this is a very clear description about how to...

A kaleidoscope is constructed using polarizing polymer paper and then low-density polyethylene, high-density polyethylene, and polypropylene are all melted onto individual glass slides and examined through a microscope. The intent is to...

Young scholars examine elastomeric polymers in a lab activity in which they design a bungee cord. Students must determine the tensile strength, percent elongation, and plot stress versus strain graphs for their experiments on rubber...

A simple activity goes a long way in demonstrating the property of porosity to your rock hounds. They will mass a specimen of dry sandstone and then soak it in a pre-measured amount of water. After seven minutes, they once again measure...

Another A+ lesson on the impact of climate change comes to you from the National Earth Science Teachers Association. In this installment, learners model the stratification of water in lakes due to temperature differences. The lab also...

Geometry students will be ecstatic about these engaging and enlightening end-of-the-year projects! Types of project ideas include interviewing a geometer, an ABCs of geometry poster, an engineering lab report, and origami work. 

How do you engage pupils in a discussion about osmosis without leaving them overwhelmed? By providing them with the tools to perform an exciting experiment, and they will see osmosis in action! Young chemists and biologists use...

Students examine potential contamination on the environment due to products and by-products of a new industrial process. Students conduct a lab that explores the economic differences between choices of pollution cleanup and prevention.

Students are introduced to bacteria and their role in biology and finishes with a lab experiment that focuses on antibiotics. They are given an overview of the important concepts involving bacteria and their potential resistance to...

High schoolers explain the following processes: bacteria transformation, genetic recombination, and antibacterial breakdown of bacteria. They follow lab protocol and use the scientific method: to make predications, and to explain an...

Students investigate nutrient cycling in a simplified desktop ecosystem involving aquarium and hydro-ponically grown plants. They set up an aquarium with 10 gallons of water at least a week before the lab is planned and place...

Amateurs of alternative energy build a mini parabolic-trough solar energy collector and use it to heat water. Temperature is recorded over a three-minute period and the data is graphed and analyzed. Note that in order to paint aquarium...

On Earth, a candle flame points up, but on the International Space Station, it forms a sphere. Young scientists practice their skills by recording observations before, during, and after a candle burns. Chemical and physical...

Students extract DNA and test for its presence from unroasted (raw) wheat germ using a prescribed procedure. They modify the procedure to provide a less expensive, easier method. They also extract DNA from different available plant,...

In this ester worksheet, students mix organic acids with alcohols to produced esters and identify the products by the chemical reaction and the scent given off after the reaction occurs.

If students use and store kitchen equipment appropriately as well as utilize sanitary work habits, the foods laboratory will be a safe and easy place to work. See Preface Materials: As a motivator ask: "Why should I worry whether or not...

In this polymer worksheet, students make two types of cross linked polymers and they test their physical properties. These include their response to agitation, stretchability, viscosity, and resilience.

Students explore water density and design a hydrometer to measure density. This activity is part of Ocean World's home site and excellent resources and links are provided.

Learners classify different mixtures. In this mixtures lesson plan, students determine samples to be suspensions, colloids, or solutions and compare homogeneous and heterogeneous mixtures.

Young scholars produce copper metal by electrolysis. In this REDOX lesson plan, students use a copper (II) chloride solution and a 9 volt battery to produce copper metal through an electrolysis reaction. Young scholars make observations...

In this groundwater worksheet, students simulate a pumping well and a pumping well near an injection well using plastic bottles and dirt. They use food coloring to act as a contaminate to see the movement of food color into the water....

In this relationships and biodiversity instructional activity, high schoolers investigate the relationships between 4 plants sample using 7 different tests. These include looking at structural characteristics of the plants, seeds and...
