energy
4-PS3-1. Use evidence to construct an explanation relating the speed of an object to the energy of that object. [Assessment Boundary: Assessment does not include quantitative measures of changes in the speed of an object or on any precise or quantitative definition of energy.]
4-PS3-2. Make observations to provide evidence that energy can be transferred from place to place by sound, light, heat, and electric currents. [Assessment Boundary: Assessment does not include quantitative measurements of energy.] 4-PS3-3. Ask questions and predict outcomes about the changes in energy that occur when objects collide. [Clarification Statement: Emphasis is on the change in the energy due to the change in speed, not on the forces, as objects interact.] [Assessment Boundary: Assessment does not include quantitative measurements of energy.] 4-PS3-4. Apply scientific ideas to design, test, and refine a device that converts energy from one form to another.* [Clarification Statement: Examples of devices could include electric circuits that convert electrical energy into motion energy of a vehicle, light, or sound; and, a passive solar heater that converts light into heat. Examples of constraints could include the materials, cost, or time to design the device.] [Assessment Boundary: Devices should be limited to those that convert motion energy to electric energy or use stored energy to cause motion or produce light or sound.] *Order Potassium Chlorate from Frey Scientific (I need to find a lab grade test tube or ceramic & clamp) for Gummy Bear Energy Transfer* 1 What is energy? -Clips & images: What is energy? What do we mean by do work? -Journals: Table with Form / Generate / Application -For each type, watch clips and images, discuss, and fill in tables. -day 2: Bill Nye + Gummy Bear Energy Transfer -List All the Forms We Experience in Daily Life 2 How do we generate and transfer heat energy? -Clips & Images: How do we generate heat? -Clips & Images: What work can it do (emphasis transfer from warmer to cooler)? -Clips & Images: Can it be transferred to other forms of energy? -Day 2 Solar Bag -Draw diagrams of solar bag, including state change, density, and pressure changes. 3 Start Snap Circuits 1- What does mass measure? -density video -Pass out object cards (2 identical sets). Arrange 1 set in order of mass. Arrange the other in order of density. -Explanations in journal: How can two object that are the same size have different masses? Which has greater mass? Which has greater density? -Day 2: comparisons in groups: small balloon and solid of same size, cup of water and cup of air, water in 3 states, common materials 2 (1 day) What is gravity and how do we measure it? -review mass -slides and videos: gravity, weight https://www.youtube.com/watch?v=6MJ0lTEhoL8 -Gravity videos and slideshow: Does gravity push or pull? What does it push or pull on? What makes it stronger or weaker? -Visuals: Units & Weight: Do you think weight is the same everywhere (constant)? -Video: Mass is constant; weight is not. -Calculate mass and weight on different planets. -Spring scale demonstration and diagrams. 3 (2 days) Why do you need two measurements to calculate rate (v=d/t)? *Have students bring in scooter and skateboard for tomorrow. -Slides and Videos: distance, time, per -What does it mean when a car is going 35 mph? What does the per mean? -Put my bike on bottom bracket rack: Why is this measured in revolutions per minute? -Rate slideshow: Why do you need two measurement for rate (the amount of change) per (the time it took to change)? -Show different rate formulas: Why do they all mean the same thing? -Do a few task sheets to preview tomorrow -Day 2: Task sheets to calculate rate with either distance or time given. (# times legibly write name per minute / bike revolutions per minute on video loop / flat paper drop per second /tennis ball 3 bounces from desk height per unit of time / if time: 3 steps per unit of time / one pencil sharpened per unit of time / multiplication math facts per minute) 4 (1 day) How can you compare speed and distance if time is equal? -Have students scoot, skate, and walk for equal time. -How can you compare distance and speed because the time is equal / constant? -Velodrome Video Problem -Rote word problems. 5 (1 day) How can you compare speed and time if distance is equal? -How can you compare their speeds? -What is controlled? Measured? Manipulated? -How can you compare their speeds? -Is this a fair test? 6 (2 days) Calculate speed given distance and time -Slideshow: Units of Time and Distance. What units would you use for each scenario. -3 Act Math: Glowstick, Pencil -day 2: More 3 Act Math (skydiving problem?) and rote word problems. |
