Ask "how do you know?" in appropriate situations.
|Sink or Float?|| |
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.
|"Handy" Constellations|| |
This lesson allows students to explore constellations, starting with Gemini. Students will learn about constellations and learn that there are more stars in the sky than anyone can easily count. Students will create a constellation of their own using the outline of their hand. At the end of the lesson, the students will understand that constellations can be viewed differently by others. A worksheet will be completed as a summative assessment.
|Observation: The Stars in the Sky|| |
This is part one of a thematic unit that will take approximately one week to complete with one hour for each day. Students begin be looking at a picture of the stars to peek their interest in the unit and begin to form questions about the stars as the unit goes on. 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.
|Night Journals|| |
This project engages students in data collection as they record their observations of the stars over a month-long period. Teachers keep a class journal (recording their own observations) and students will record their observations each night in their journals by drawing what they saw. Discussion and a follow-up activity involving marshmallows emphasize the multitude and placement of stars.
|Properties of Solids|| |
This lesson (intended to be used with other sorting lessons) allows students to understand the basic concepts of matter and properties of solids. This lesson involves the creation of a vocabulary chart with a child-friendly definition of matter and a Thinking Map with the varying properties of solids that students can use to sort different objects. Students explore two different objects and record their observations about the objects' properties.
|Some Things Happen Fast and Some Things Happen Slow|| |
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.
|Tree Observations|| |
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.
|Push and Pull Magnet Art – an Engineering Design Challenge|| |
This Engineering Design Challenge is intended to help first grade students apply the concepts of the various ways objects can move, and that the way to change the motion of an object is to apply a push or a pull. It is not intended as an initial introduction to this benchmark.
|How do Objects Move | Engineering Design Challenge|| |
In this unit, students explore and explain the many different ways that an object moves and how its properties affect its movements. In one lesson ("In What Ways"), students predict and test their predictions on how different objects will move when gently pushed on their desks. In "Do All Tops Spin Alike?," students use different materials to construct their own tops and test its movements. "Making Objects Move" introduces the concept of acceleration and allows students to use different sizes and types of balls and other materials to build tracks that will be used to stop the ball at a certain location. "Playground Equipment" gives an engineering experience by engaging students in a competition with a given scenario and asking them to design, test, and re-design (if necessary) a functioning piece of new playground equipment (the terms "force," "motion," "gravity," and "simple machine" are introduced).
|Observing and Sorting|| |
In this unit, students learn to make observations that clearly distinguish specific objects from others and how to sort items by different attributes (eg, color, size, weight).
These lessons allow students to explore how magnifiers work by using different types of magnifiers to observe classroom objects and their own creations.
