..................................................... Use the following graphic organizer and pictures to help students keep track of which objects float and which objects sink. You may want to create your own larger graphic organizer to include more items. 1. Using the page of pictures‚ ask students to predict whether each item will sink or float. 2. Ask students to cut out the pictures of the things they are testing. If you are using additional items‚ provide a similar sheet with pictures of those

This experiment explores how salt and sugar affect the melting rate of ice in water. Research Questions: * Does adding salt to ice and water slow down‚ speed up‚ or not change the rate the ice melts in the water? * Is salt the only substance to have this effect? What about sugar? Knowing how to speed up the melting rate of ice is very important information for anyone who needs to de-ice roads or driveways after a winter storm.
