Students explain how uneven heating of Earth affects wind and water currents. They describe the limits on current technology in predicting weather and how the Water Cycle is related to local weather.

Students begin with an overview of the Earth's interior and how volcanoes form. They learn how engineers predict eruptions. In a class demonstration, students watch and measure a mock volcanic eruption and observe the phases of an...

Sixth graders investigate a flower plant and the plant cycle. They extend observational skills when looking at a tree by observing, questioning and sharing ideas. They observe a living and nonliving flower and compare and contrast how...

Second graders conduct an a water cycle experiment. For this water cycle lesson, 2nd graders observe a puddle of water, they predict how it got there and what will happen to it.  Students watch a demonstration on the water cycle and...

In this succession worksheet, students build an ecosystem using a jar, water, bird seed, soil and a water plant. They predict what their ecosystem will look like in 3 weeks and draw a diagram. Students record their data over the course...

Sixth graders look at toys in space. In this gravity lesson, 6th graders make predictions about what different toys will do with zero gravity. They watch a space video and see what happens to these toys in space.

Students tour a cave and observe fractures in the cave's ceiling. They record characteristics of the fracture. They locate three major passages in the cave and ten major fractures.

Students explore the causes of erosion and observe how different surfaces erode differently. They recognize erosion and predict what type of erosion caused it. In addition, they predict the outcomes of erosion on different materials.

Students examine why humidity changes throughout the day. They study the concept of relative humidity, absolute humidity, and dew point temperature. They interpret phase diagrams and explain why relative humidity typically falls and...

Students predict and test different variables that would effect sugar cubes dissolving in water. In this dissolving lesson plan, students have 4 petri dishes with 4 different variations of sugar cubes and water. They predict which will...

In this chemical reaction worksheet, students experiment with soda and Mentos candy to observe a chemical reaction. Students describe the reaction, identify the investigation as descriptive or qualitative and make a prediction if the...

First graders ponder the question of how plants help their lives. They observe and compare properties of several different plants. Differentiate between living organisms and nonliving objects.

Students observe seeds growth and examine the different parts of the seedling. In this biology activity, students compare the growth of seeds planted in soil and in hydroponics. They record their observations in their science journal and...

A food web consists of complex food chains and the more complex the web, the better likelihood of survival. Learners compare and contrast food webs and food chains and discuss concepts like the predator-prey and consumer-producer...

Fourth graders investigate how the water cycle is vital for all living things to survive on Earth. They observe the teacher set up a simulation of the water cycle using a Plastic Earth Simulator, desk lamp, and water, and make...

Students create bleached designs with the sun's bright light. In this early childhood science lesson, students use their observation and prediction skills as they explore the sun's bleaching power.

Students design and create a worm and worm free compost tanks for observation of decay in ecosystems. They make predictions, care, and revist tanks using their journals for observation and data collection.

Third graders compare the bouncing height of different types of balls. In this science instructional activity, 3rd graders explain the importance of repeated experimentation in science. They record their result and share them with the...

Fourth graders observe what is happening when an Alka-Seltzer tablet is placed in a clear cup of water. They observe the release of carbon dioxide gas. Pupils answer the question of how much as is released by observing the experiment...

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...

Learners determine that the rate of reaction is affected by temperature, surface area, concentration of reagent, and addition of a catalyst or inhibitor. They observe that on December 3rd, 1984, 8000 people died when the chemical plant...

Third graders access prior knowledge of the monarch butterfly and discuss what they would like to know.  In this Monarch Butterfly instructional activity,students read Monarch Butterfly and discuss the life cycle of the butterfly....

Learners examine the observed world, molecular world, and the symbolic world of chemistry. They observe a demonstration of the conductivity of solutions, describe the properties of acids and bases, and predict the outcome of solution...

Learners build and observe a simple aneroid barometer to discover changes in barometric pressure and weather forecasting. They graph changes in barometric pressure for two weeks and make weather predictions.
