Protein

Monday, November 15th

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

Wait 1 full minute

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

Some: Yellowish green

None: Yellow

⁠

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

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):

1) corn seeds and record

2) squash seeds and record

3)bean seeds and record

Notice: Did the seeds gain, lose or keep the same mass? Why do think that happened?
