Students investigate how size affects large and small animals differently. In this animal lesson plan, students determine how size affects different animals by constructing their own animal out of marshmallows. Once students create...

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 plan is...

Milk does a body good ... unless, of course, someone is lactose intolerant. Pupils play the role of pharmaceutical scientists in a guided inquiry lab about lactase. Lab groups collaborate to learn more about lactose intolerance, how...

Students use the TI-83 + linked to the CBL2 and temperature probes to perform an experiment. Each of the temperature probes is placed into a different cup, one insulated and one not insulated. Each cup holds warm water. The two cups are...

Students investigate the effect of temperature on cold-blooded animals, using a 5 x 8 inch index card to represent a dinosaur as their model organism. Students measure temperature changes that occurs at different angles to a light...

Earth science enthusiasts experiment to compare the heating rates of soil and water. They relate their findings to the weather conditions near bodies of water. Consider also having middle schoolers measure the cooling rates to...

Learners conduct an experiment to determine what type of clothing would be most suitable for outdoor activities. They determine the temperature changes of the skin under various wet clothing materials and graph the temperature changes. ...

Clouds are nature's insulator! A lab investigation asks learners to use an infrared thermometer to measure differences in infrared temperatures. They find that pointing the thermometer at a cloud has a much different result than pointing...

How do dams support bodies of water? Scholars engage in a hands-on STEM activity where they design, build, and test dams to learn about bodies of water and how humans use natural resources. They learn how criteria and constraints affect...

Never let them see you sweat ... unless you can't help it! Scholars design an experiment to determine the effects of stress on the body. They monitor sweat production under different conditions and relate the response to the function of...

Second graders investigate the meaning of temperature. They determine what happens to a thermometer when the temperature rises or falls. They place thermometers in different classroom locations in order to compare the temperature in a...

Students are taught how enzymes enable chemical reactions to occur a body temperature and how the lack of enzymes in the body can cause problems in the break-down and absorpion of nutrients. They match up different enzymes with the...

Remind your middle school scientists how fox ear size varies depending on the climate they live in; large ears allow heat loss while small ears keep heat in. Discuss how a cold-blooded animal might try to regulate body temperature. Then...

So many bodily activities depend on homeostasis! Give learners a solid background to understand the basic process of the human body. Scholars first examine negative feedback loops contributing to body temperature regulation and then a...

Why is lactase important? Biology scholars explore enzyme function in a structured inquiry lab. The activity tasks lab groups with observing how temperature and pH affect enzyme activity, as well as determining which milk products...

Hosting a Healthy Field Day will take a lot of planning and organization, but with a lot of parent participation it can come together very well. The resource describes seven stations of the ten that were presented. Each of these has a...

Students examine how the human immune system responds to germs and explain what a fever is. They design a thermometer in order to further explore temperature before completing a temperature conversion worksheet. They detail the work of...

Students explore Boyle's Law. In this Boyle's Law lesson, students complete problems involving Boyle's Law. They examine the effects of Boyle's Law upon the human body. Students use the Internet to complete a lab activity.

Second graders experiment with a thermometer and water samples of varying temperatures. They examine the effect different colors and different fabrics have on retaining heat. They examine snow samples for water and dirt content. They...

Condensing water warms the air around it. Young scholars consider this concept as they experiment with air temperature around evaporating and condensing water vapor. They simulate the formation of clouds to experience the associated...

Students experiment with water density, temperature and salinity. In this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.

Students discuss the functioning of the digestive system and the specific enzymes present. They observe the action of amylase on starch to identify characteristics of enzymes then perform an experiment on the effects of temperature on...

Students test water to determine the dissolved oxygen content while displaying the proper use of testing instruments while visiting water testing sites. They determine if the amount of dissolved oxygen is appropriate for the tested...

Students collect data on the cooling of water in two different test tubes, one that is wrapped in wet newspaper and one in dry newspaper. They then relate this cooling effect to the body's perspiration.
