In this lab activity, students design an experiment controlling one variable with the goal of growing a plant taller than a control plant.
In this lesson, students investigate forces such as pushes and pulls. Students use simple objects such as toy cars, cylinder blocks, tops, cubes, and yo-yos to experiment and observe movement. Students then classify the different types of movement such as up and down, side to side, and rolling. Specific vocabulary related to movement is introduced at the end of the lesson.
In this investigation, students will look at a number of videos, animations, and images in order to gain a better understanding of how hurricanes work. In the first part, students will learn about some of the satellites that researchers use to study and make forecasts about hurricanes. Then students will get a chance to look "under the hood" of a hurricane to see how these storms develop.
In this section students will learn about The Saffir-Simpson Hurricane Scale.
In this activity students will learn how researchers use satellite data to study and forecast hurricanes.
In this activity students will learn about advances in computer models and observational methods which have made it possible to learn more about how hurricanes develop.
In this activity students will examine some visualizations of cyclones that occurred south of the equator. Students will be asked to draw conclusions about how these storms differ from those that North Americans are familiar with.
In this unit students will learn about hurricane season and patterns of hurricanes.
In this instructional module, students will learn about hurricanes and how they form. They will also investigate the factors that influence strength and intensity of hurricanes and how warm ocean waters fuel them.
In this lesson, students will observe clouds in the sky for a week during science class and discuss what the weather is like when we see certain clouds. During the second week the students will observe the clouds at home and keep a journal of the clouds they see.
In this lesson, students are presented with fossils and other earth materials and given clues as to their origin. After identifying the fossils and materials, they will form a hypothesis as to how they were formed and what is was before preservation.
In this lesson, students discuss, observe, and "play" with familiar sports equipment to learn about motion. Students freely explore the equipment in small groups and record what they have learned about motion, then share and discuss with the whole group. A whole group chart is created at the end of the lesson to record what students have learned about motion.
In this activity, students are asked to develop a scenario where two businesses would be likely to engage in cuthroat competition with each other.
In this lesson, students participate in a guided discussion to direct them to think of complex machines that we use every day. They will also group machines into groups of similarities, identifying the six types of simple machines.
In this inquiry investigation, students will use basil to see if growing conditions will change the taste of the herb. Students will test basil in different growing conditions while also comparing it to a controlled variable. Students will keep a science journal of their investigation. Also, students will create a poster and lead their own poster session about the results of their investigation.
In this biology field investigation, students investigate the site of a local dsiturbance such as a tree fallen in a forested area. Students will identify plant and animal life within a specific area containing the fallen tree and compare it to an adjoining forested area. Students will map both areas. Students will write a lab report including their data and an interpretation of the current situation at the site.
In this activity, students will use a variety of chips to investigate how to classift objects based on their similarities and differences. Students will use technical writing to explain their keys and communicate their conclusions.
This activity can be students' first exposure to using Direct Measurement Videos in physics. Students will use a video to make measurements that will allow them to calculate the speed of a roller coaster. This activity will also help students understand the concept of average velocity.
In this inquiry investigation, students will use microscopes to observe slides of unknown tissues representative of the major groups found in the human body and then draw their observations in a science notebook. They will then work in groups to develop unique classification schemes for the tissues that are presented to the class.
In this lesson, students will act out open and closed circuits as a whole class with some students acting as the "motors" or "light bulbs." It is followed by individual journal writing and a class discussion.
