Investigate how temperature affects the density of water and stratification that occurs in bodies of water when temperatures vary. Water of differing temperatures is given different colors to see the layers that form. The lesson is meant...

Use the pump from a spray bottle to drive a model of the heart in action! In addition to modeling the function of the heart and blood vessels, aspiring anatomists also simulate arterial blockage. They compare the effects of increased...

A combination of informative text, photos, and graphics comprise this sharp show on electromagnetic radiation. Some slides mention hands-on activities for demonstrating concepts, so if you want to include them you will need to figure out...

Here is a lab activity where teens experience the respiratory system first-hand as they dissect lungs and identify key structures within the system. Although the website is written in British English with some slightly different verbiage...

Preparing the root tip samples is the most challenging part of the mitosis-viewing lab found here, but the directions help ensure you have everything you need. There is no worksheet included; however, there is a sample data table....

Students analyze and experience the scientific method. They discuss the various steps of the method, conduct various experiments, and write a three-paragraph essay regarding their conclusion.

Students examine the different techniques that may be used to reduce carbon dioxide in the atmosphere.  In this ocean pollution lesson students divide into groups and complete a lab to see how the ocean holds carbon dioxide.

Students investigate how geologic sequestration reduces carbon dioxide concentration in the atmosphere. In this earth science lesson, students simulate oil mining in the lab. They write down their observations and complete the lab report...

Students participate in a lab experiment to observe and measure the opening and closing of stomata. They focus on photoperiod, locate and identify stomata on a leaf and explain the role of stomata in the daily functioning of a plant.

Students explore epidermal cells. After following specified procedures for removing epidermal cells from their wrist, students view the cells with the use of a microscope. After creating a drawing of their observation, students label the...

Learners participate in a review of diffusion and the basic properties of the cell membrane before exploring the process of osmosis in a lab activity. Using shell-less eggs that have soaked in various solutions, students make...

Students study the characteristics of living things and explore the characteristics of viruses including their structure, function, and reproductive cycles. They also explore the impact of viruses on human health by discussing common...

Young scholars conduct an experiment in small groups, draw conclusions about the amount heat of a compound achieves and practice their data analysis skills.

Seventh graders explore bar graphs and pie charts. Given a pack of M&Ms, 7th graders explore the colors, sort the data in a frequency chart and then construct bar graphs and pie charts to categorize the M&Ms by color. Students...

Students explore echolocation of animals. They examine how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight. Through experimentation, they discover how sound waves...

Fourth graders explore several different types of graphs using M & Ms.

Students develop problem solving, decision-making and inquiry skills by planning experiments. They conduct systematic observations, interpret and analyze data and draw conclusions then communicate their results.

Learners review the following vocabulary: Independent assortment, multiple alleles, and polygenic traits. They review their vocabulary by the "quiz, quiz trade" routine. Students work in groups. They are given one set of gene cards...

Students inspect a given problem and come up with a hypothesis. In this investigative activity students come up with a hypothesis for a problem, test each hypothesis and evaluate how successful each one was. 

Second graders create a graph about TV watching. In this bar graph lesson, 2nd graders make a hypothesis about how much TV 2nd graders watch per week. They record their TV watching for a week and bring it to school to create a class...
