Students examine how ice changes state and when  its volume changes.  In this mass lesson students complete a lab that shows them how waters volume can change. 

Which of the following can you survive without for the longest time: water, food, or a positive mental attitude? The answer may surprise you. Guide learners of all ages through games, activities, and discussions about surviving in the...

Laughter may be the best medicine, but aspirin is also important. Young chemists analyze aspirin tablets using titration in this lab experiment. They then repeat the entire experiment using a different aspirin brand. 

Visuals help clarify claims. Scholars create visual displays to accompany their end-of-unit presentations about water sustainability. Using blank paper and their notes from the unit, they put their creativity to good use and then...

You can never be too young to get involved in composting or recycling. Here is a instructional activity that has been made for the very littlest learners and it's all about the importance of conservation. They'll sort compostable and...

Radioactive isotopes have a wealth of uses, but their waste may cause some concern. One of four free-response questions challenges learners to devise a waste removal strategy for medical radioactive substances. Other questions address...

It's the half-way mark! Pupils demonstrate understanding of unit standards by completing a mid-unit assessment. After reading an informational article about water management strategies, scholars complete a graphic organizer to identify...

How do animals adapt to weather changes? Provide your class with the ability to understand adaptations and body temperature as they participate in this hands on experiment, using fake fur and hot water. Pupils collect data and...

After nine lessons and activities about energy, here is the final assessment. The 20-questions include multiple choice, multiple choice with justification, short answer, answer analysis, and labeling diagrams to challenge learners.

Save the oceans! The 22nd installment of a 23-part NOAA Enrichment in Marine sciences and Oceanography (NEMO) program focuses on laws and marine policy. Pupils take part in an activity investigating fisheries stock data.

The earth is a delicate and fragile thing; Why not engage your class in a craft project that will make them aware of our environment? Earth Day is celebrated as recycled materials are used to create earth window hangings. Crayons are...

Don't desert a resource on the desert! Scholars work in groups to build on their ideas from the previous lesson to design a sustainable guest village in the Saguaro National Park. Each group produces a PowerPoint presentation to share...

Even rivers have tides. Older elementary schoolers will discuss the Hudson River and how weather, water craft, and the ocean cause tidal fluctuation. They will examine a series of line graphs that depict tidal fluctuation, then analyze...

Students view examples of different types of erosion. In this erosion lesson, students discuss the different types of erosion and how erosion changes Earth. Students explore erosion and the effect it has on engineering.

First of three lessons, this is a great start to a unit on energy. As you demonstrate, learners discover different types of energy and how it is converted from one form to another. They then focus in on the generation of electricity by...

Students understand that most substances may exist as solids, liquids, or gases depending on the temperature, pressure, and nature of that substance. This knowledge is critical to understanding that water in our world is constantly...

High schoolers map connections among raw materials. For this environmental stewardship lesson, students design strategies to minimize the use of raw materials and discuss how to use more sustainable materials.

Students explore the Law of Conservation of Matter using effervescent tablets.  In this mass and energy lesson, students investigate how mass is conserved in the reaction of effervescent tablets and water. They will discuss and...

Students will observe the amount of water in an open container over time and also examine the amount of water in a closed container over time. They then will compare and contrast the sets.

Young scholars observe and interpret historic photographs of water in New Mexico. They record observations, draw inferences, and compare water in New Mexico's past with water today. They create a class book or exhibition of the...

Students explore the importance of water conservation and investigate how plants clean water.

In this water conservation game, students collaborate with classmates to play a game about saving water. Students form groups and use the provided game boards and pictures to study water conservation.

Students investigate air and water pollution, and the conservation of natural resources.

Students identify the sources of water on Earth. In this life science lesson, students list the different plants and animals that live in the ocean. They explore marine objects in the lab and draw them.
