What kind of container would keep your ice water the coldest for a period of time? Conduct an investigation using different kinds of containers (you might even make your own). Use a thermometer and record the temperature of the ice water after 5 minutes. Can you test out different designs that will keep your water cold using materials found around the house?
Make a rocket out of household materials. Adjust the design of the rocket and/or the amount of baking soda or vinegar you use. Keep a log of what you observe. Measure how far your rocket goes based on the changes you make to the ingredients or the design of your rocket.

Place different objects in a container filled with water. Watch and record what happens to each of the objects. What objects floated? What objects sunk? Make a record of each object you used and whether it sinked or floated. What did the objects that sunk have in common? What did the objects that floated have in common?
