I will explain to kids that I have two different ice cubs to drop in the water; one made with ice, one made with canola oil. I will take the ice cube made with water and ask students whether they think it will float or sink? We will then test it out. After, I will grab the ice cube made of oil and ask students the same questions. Do you think the ice cube made with oil will float or sink? We will then test it and see if it floats or sinks. I will then ask kids, how is one ice cube floats and one sinks? I will then explain that today we will make an object that floats sink, and an object that sinks float.
Assessment of prior knowledge: After students have observed the attention grabber. I will use the white board to assess student’s prior knowledge. Several objects will be present on the white board. I will ask students; last class did this object float or sink? Students will then vote with their feet. Students that think it will float will head to one side, and ones that think it will float will head to the opposite. We will then check students’ answers by using the magnifying tool on the white
