1 Colour Mixing Tools: Extras: Food colouring; water Key Science Concept: Primary colours mix to make secondary colours. Learning Resources, Ltd. 1

2 What to do: Fill the large test tube, almost to the top, with water. Add 5 drops of red food colouring, put the lid on the test tube and shake. Remove lid. Fill the small test tubes, about halfway up, with water. Add 3 drops of yellow food colouring to one of the small test tubes, put the lid on and shake. Remove lid. Add 3 drops of blue food colouring to the other small test tube, put the lid on and shake. Remove lid. Fill the eyedropper with red water and squirt it into the yellow water. Put the lid on and shake to see the new colour. Now mix red water with the blue water. Shake to see the new colour. Try mixing other colours together. Made in China.

3 Shiny Pennies Tools: Extras: Dull pennies; water; lemon juice; paper towels Key Science Concept: Lemon juice is an acid. Water is not an acid. Learning Resources, Ltd. 2

4 What to do: Use the tweezers to drop a penny in each small test tube. Fill the beaker with water. Use the eyedropper to transfer water from the beaker to one of the test tubes. Put the orange lid on the test tube. Pour some lemon juice in the other test tube. Put the yellow lid on the test tube. Wait 10 minutes, then use the tweezers to remove the pennies from the test tubes and place the pennies on the paper towel to dry. Which penny is shinier? The penny that was in the lemon juice is shinier because the lemon juice is an acid and the acid broke down the tarnish on the penny. Made in China.

5 Investigating Insects Tools: Extras: Insects Key Science Concept: Insects have 3 body parts, 6 legs and 2 antennae. Learning Resources, Ltd. 3

6 What to do: Take your magnifying glass outside to look for insects. When you find an insect, use the tweezers to pick it up and then put it in the test tube. Put the lid on the test tube. Use the magnifying glass to look at the insect up close. Look for 3 body parts, 6 legs and 2 antennae. Release the insect back outside and find another insect to look at up close. Do not keep the insect in the test tube for more than a minute or two. Made in China.

7 Seeds and Sprouts Tools: Extras: Variety of seeds; soil; water Key Science Concept: Seeds grow into plants. Learning Resources, Ltd. 4

8 What to do: Look at the different kinds of seeds using your magnifying glass. Fill each test tube halfway with soil. Put a small hole in the soil and use the tweezers to drop a seed in each hole. Add a bit more soil to cover the seeds. Fill the beaker with water and use an eyedropper to slowly add water to moisten the soil. Put the test tubes in the stands and place them near a window. Do not put the lids on the test tubes. Check the plants daily and make sure the soil is moist. Use your magnifying glass to look closely at the roots and sprouts as the plants start growing. Draw pictures each day to chart your plant s growth. Made in China.

9 What s That Smell? Tools: Extras: Cotton balls; variety of items with a distinct smell such as coffee, cinnamon, flower petals, vanilla, perfume, etc. Key Science Concept: Your sense of smell is one of your five senses. Learning Resources, Ltd. 5

10 What to do: Place one item to smell in each test tube. Ask a friend to sniff each test tube without looking. Can your friend correctly identify each smell? Repeat this experiment with new smells. Try pouring a bit of liquid, like perfume or vanilla, onto a cotton ball. Then, use the tweezers to drop the cotton ball into the test tubes. Clean the test tubes well (with soap and water) before reusing. Note: Always check with an adult before choosing items to smell. Made in China.

11 Sink and Float Tools: Extras: Water; small objects such as coins, cotton balls, cereal pieces, rocks, raisins, small toy pieces, cork, etc. Key Science Concept: Objects sink or float in water. Learning Resources, Ltd. 6

12 What to do: Fill the beaker with water. Select a few objects to be placed in the water. Predict which objects will float and sink. Use the tweezers to place objects into the water. Watch what happens to each object. Did you predict correctly? Repeat this experiment with new objects. Made in China.

13 Mixing Impossible Tools: Extras: Water; cooking oil; blue food colouring Key Science Concept: Oil and water do not mix. Learning Resources, Ltd. 7

14 What to do: Fill the beaker with water and add a few drops of blue food colouring. Place the funnel in the test tube and pour the blue water through until the test tube is half full. Use the eyedropper to squirt about 10 drops of cooking oil into the test tube. Put the lid on the test tube and shake. Place the test tube back in the stand and watch the oil and water separate. Clean your science tools with soap and water before using again. Made in China.

15 Dancing Raisins Tools: Extras: Clear fizzy drink; raisins Key Science Concept: The fizz in fizzy drink is called carbon dioxide. Carbon dioxide is a gas that creates bubbles. Learning Resources, Ltd. 8

16 What to do: Pour the fizzy drink up to the 1 line of the beaker. Use the tweezers to put five raisins into the beaker. Put the glasses on and use the magnifying glass to observe the raisins. Can you see the raisins moving in the beaker? Tiny bubbles from the fizzy drink collect on the raisins and cause the raisins to float to the top. When the bubbles pop, the raisins sink again. Made in China.

17 Colour Changing Celery Tools: Extras: Food colouring; celery stalk; water Key Science Concept: Plants absorb water and the water moves upward through plants. Learning Resources, Ltd. 9

18 What to do: Fill the beaker to the ½ line with water. Add 15 drops of food colouring any colour. Place the celery stalk in the water. Make a prediction about what will happen. Observe the celery as it starts to change colours. Try the same experiment with a white flower. Made in China.

19 Mini Volcano Tools: Extras: Bicarbonate of soda; vinegar; paper towels; red food colouring; water Key Science Concept: Acids and bases react to make bubbles of foam called carbon dioxide. Learning Resources, Ltd. 10

20 What to do: Place the beaker on a layer of paper towels. This is the volcano. Fill the beaker to the ½ line with water. Put the glasses on. Add 2 spoonfuls of bicarbonate of soda to the water and stir well. Pour some vinegar into the small test tube and add 5 drops of red food colouring. Put the lid on and shake. Use the eyedropper and squirt the coloured vinegar into the beaker. Watch the lava flow up from this mini volcano. Made in China.
