Goal:
Find out what foods have protein Find out how protein moves through the digestive system
First: Find out how much protein is in each food (you will test 1-2 foods)
Gather 1 of everything: a tray, 1 food in a cup, forceps, a cup of water with a pipette, 1 protein test strip, 1 plastic portion cup Mass about 1 gram of food into the portion cup Break food apart with forceps spoon of fingers into tiny pieces Add 1 full pipette of water and mix with forceps or toothpick Put protein test strip in for 1 full second (one one thousand) Set strip next to food and wait for one full minute Check your test strip and record: Yes: blueish green to blue Pass your food to the next person and repeat with the next food Second: Track how protein moves through the digestive system
Use this graph and your table handout to track how the amounts of these two nutrients are changing as they move through the digestive system Protein and Amino Acids 2
This is the end of a protein molecule These are nutrients called amino acids
Talk to your partner about the following:
Q: How is the protein similar to and different from the amino acid nutrients? Q: What is happening to protein as it moves through your digestive track? Take a photo of your answer with your table’s ipad
Optional Extra: Use atom models to build and write the formula for the two amino acids shown above. Take a photo when you have made one or both.
Last - if there is time : Check your plants
Get out your Sprouting Seeds Data Gather a scale, the seedling tray that matches your seed number, the 3 small portion cups that match your number Use the scale and portion cups to carefully find the mass of (remember to subtract the mass of the cups): 2) squash seeds and record Notice: Did the seeds gain, lose or keep the same mass? Why do think that happened?
Protein
