Middle schoolers create their own sling psychrometer to measure relative humidity. They work together in groups to make and use the psychrometer. They are asked questions about their experiment to complete the lesson.

Students construct a sling psychrometer and they measure the relative amount of humidity in the air. They create their own experiment on how to construct a sling psychrometer and how they are going to measure the relative humidity in the...

Students predict the location where the relative humidity the highest and lowest in and around their school. They use a sling psychrometer to measure the relative humidity of the various locations.

Elementary and middle schoolers participate in a demonstration of the heat and humidity of the Manu rainforest environment. They watch and discuss a video, calculate the humidity and temperature in the humidified tent, and write a...

Young scholars use the scientific method to investigate the role of temperature in microbial growth. In this food preservation lesson, students set up an experiment with fruit in room temperature and in a refrigerator. They record the...

Students review their prior knowledge on biomes and ecosystems. At a local Christmas tree farm, they work together in groups to identify the changes occuring in the area. They participate in solving a mystery in which they determine the...

Young scholars examine the phases of the water cycle and water's different forms it can have. They work in groups to create pantomimes to illustrate the water cycle to their classmates.

Students use weather measuring devices to record and study weather conditions at different locations, during different times. They attempt to draw conclusions about the relationship between weather conditions, lunar cycle and fishing...

Students take a field trip to an old Christmas tree farm near their school. In groups, they gather data at the site and analyze the data in an attempt to discover what happened to the area. They identify human activities that led to the...

In this science worksheet, students locate and identify various vocabulary terms related to earth science. There are 44 words/phrases located in the puzzle.
