Using a colorful infographic handout and a guide sheet, hold a class discussion about how a bathtub can serve as a model for the greenhouse effect created by Earth's atmosphere. Participants will understand that as energy or matter is...

Begin a full lesson on climate change by demonstrating how carbon dioxide gas contributes to increased temperatures. Be aware that pressure inside the antacid-containing bottle in Activity 2 may cause the lid to fly off; keep viewers at...

Did you know you can conserve water by drinking tea instead of coffee? Learn about other products that use larger amounts of virtual water in an online lesson. Pupils complete a series of questions to test their understanding of the...

Bathymetry is not a measure of the depths of bathtubs! Through the three lessons, scholars explore two different types of maps and how they are made. The resource focuses on topographic and bathymetric maps and teaching the techniques...

Do you think chromatography paper suffers from separation anxiety? Young chemists make soap, slime, silly putty, and experiment with chromatography in this lesson. The material includes clear instructions for each experiment along with...

Students identify ways to conserve water. For this environmental lesson, students use a water use checklist to identify how much water they use in one day. Students analyze the data and brainstorm ways to conserve water.

Students examine an ecosystem. In this food web lesson plan, students discover the importance of sharks and what threat sharks actually pose to humans. They participate in class discussions and work independently on a couple of different...

Students investigate water hardness. In this water hardness lesson plan, students determine the water hardness in 4 samples of water after buffering each. By using titration and an indicator, students can determine the amount of calcium...

Students create a model boat. In this art instructional activity, students identify what makes a boat float and use milk cartons to create their own boat.

Students investigate water density. In this water density lesson, students conduct an experiment with food coloring, water and salt to see how the salt effects bodies of water.

Students investigate the states of matter. In this physics instructional activity, students use water and ice to demonstrate the characteristics of a solid and liquid. Students record their observations as the state of the water changes.

Students predict the change in water volume when adding marbles to a graduated cylinder. In this Chemistry lesson plan, students will need to make accurate water measurements to determine the fluid displaced by the marbles. The students...

Students determine the volume of water they displace. In this earth science lesson, students calculate the total water displaced by the world's population. They evaluate whether or not this value is enough to raise the sea level...

Learn about wastewater and recycled water with a science reading activity. After learners finish a two-page passage about conserving the water supply, they answer six comprehension questions about what they have read.

Students observe what happens when the pressure of a liquid is not distributed evenly on an object.  In liquid pressure lesson students view a demonstration and see how the pressure of a liquid works. 

Have your class explore density and buoyancy using this resource. Learners read the book Who Sank the Boat, and use several items, such as rubber balls, bottle caps, wood, and other household items to conduct an experiment. Using a tub...

After reading a picture book about planting and harvesting cucumbers, learners get a chance to examine some cucumbers of their own. First, they see photographs of a cucumber on a vine, and learn that it is part of the gourd family....

What do your learners know about mining? Invite them to read about all of the materials that come from mining that go into building a house. Additionally, they answer four questions at the bottom of the worksheet.

Students make and test predictions about sinking and floating, and classify objects according to whether they sink or float.

Students will determine whether various objects sink or float in water. They do not need to explain why objects sink or float. They are rather to be encouraged to observe that the same objects will sink or float every time, i.e., that...

Students explore the school and report back any leaks they see to the teacher. They are encouraged to do this at home and report any leaks to their parents.

Students explore the function of bone, muscle, and skin. Pasta and rubber bands are used to model how minerals and collagen contribute to bone strength. The effects of the reduction of these substances are explored in chicken bones.

Students listen to a read aloud about the life cycle of the pumpkin and discuss the process. They complete a life cycle booklet.
