Jose found four turtle eggs sitting in the grass in his backyard. He plans to take them to a nature center near his house where a scientist will help them. Jose needs to design a closed container to transport them to the nature center. Two important criteria are that the eggs must be kept warm—at a temperature between 27–32 degrees Celsius (C), and the eggs must be protected so the shells do not break. Jose wants to put a packet around the eggs that meet both criteria. He sets up three different possible combinations of water, calcium chloride, and baking soda in three different sandwich bags. Each bag represents a possible design for a packet. All three bags sit for the same amount of time.
Which design should Jose choose?
