This Engineering Design Challenge is intended to help students apply the concepts floating and sinking in an engineering design challenge.

Type: Lesson Plan

This lesson helps students explore different objects that may sink or float. The teacher will begin the lesson with two candy bars. The students will be able to touch and feel the weight of the candy bars and make predictions on whether the candy will sink or float. After the teacher performs the investigation students will be broken up into groups of three to four and will look at ten different objects and predict if they will sink or float. The students will record their predictions. Fill out a table with there findings and write about why there predictions were correct or incorrect. By the end of the lesson students should understand what a prediction is. They should also understand that objects with more air float.

In this two-session lesson, students will use a real telescope to observe how objects appear closer in an artificial night sky. Students will also create a telescope model that will represent how a specific constellation looks in the night sky. The students will be using a Science Journal or "My Space Book" to make a pictorial record of their findings.

Type: Lesson Plan

Students begin by looking at a picture of the stars to peek their interest in the topic and begin to form questions about the stars. Students learn the word "observation" and then use sight to view "star jars" within groups. The class then answers questions, forms ideas, and draws pictures about what they observe. The teacher guides students into understanding that the stars are scattered unevenly through the sky, and there are too many stars for anyone to possibly count.

This is part one of a two-part lesson series. Each lesson can be done independently.

Type: Lesson Plan

In this lesson, teachers show their students pictures of different events happening on Earth and asks if these events happen quickly or slowly, how students generated that judgment, and what happens on Earth after each event occurred. Students can explore a location around the school and record observations in their notebook about what events may be occurring in that location and if they are occurring slowly or quickly.

Type: Lesson Plan

In this project, each class "adopts" a tree and collects data about it over the entire year. Teachers maintain a class tree notebook that includes a picture of the tree and a description of the environmental characteristics on each observation day as students draw a picture of the tree that day in their personal science notebooks. Emphasis should be placed on the importance of water, sunlight, and food as essential to the tree's survival.

Type: Lesson Plan

Students make predictions and test and sort a variety of objects based on whether they sink or float.
